    You don't need to wait 10 years to figure out if an oil is good. Accelerated life testing is done in various industries to determine if a product is reliable. Aeorspace and defense certainly top the list. You don't put a billion dollar satellite into orbit if you don't think the components will last 15-20 years.
  • zr2randozr2rando Member Posts: 391
    a MILLION dollar satellite if they'd used regular dino and std filters...(robz3 you set yourself up for that one...)
    Just kidding,
    No question synth is better oil...and there is nothing wrong with doing everything to the best of one's ability and just hoping for a little good luck to go with it.
    It probably would on average make a engine last longer than it would have otherwise..
    I don't smoke either but might get a broken leg and die of infection, but I'd not be coughing..
    I say if it makes you feel good do it, and talk about it to all of us heah!!
    I think we should run a oil and filter store..

    the second site should settle arguments on how the filter plays it's part in the flow of the oil, and how it can affect the pressure.
  • bottgersbottgers Member Posts: 2,030
    Thanks for the sites. I stand corrected, restricting the flow through the filter does cause a drop in oil pressure. My face is red. Oh well, the reason I come on here is to learn as much as I can. That sure surprised the excretement out of me!
  • tsjaytsjay Member Posts: 4,591
    YOU DA MAN! Thanks for those links!

    I have scanned that second one so far, and I am deifinitely going to go back over it in more detail and also check out the others.

    I guess I can do that while bottgers changes his underwear. :)

    tsjay,
    Yes, it IS hard to walk a fine line between divulging your professional credentials in order to establish credibility and remaining anonymous at the same time. Obviously, you favored the former rather than the latter. Personally, I think your credibility would have shown through even if you hid your identity better because of the detail in your posts. There are plenty of us smart enough to spot the 'real thing' as opposed to some silly faker. >;^)

    Oh, and it's good to hear that you feel there are no filters on the market that are a ‘risk’ to engines. Such was not the case with some of the brake pads I encountered while I was in that business. Also, there are currently available automotive products like methanol dry-gas and some engine flushes that should NEVER be used and I feel they should be pulled off the shelves immediately.

    I'm sure that at least SOME of the Penske oil filters (available at K-mart) are made by WIX ... but their air filters appear to be Fram (orange foam rubber seal material) ... using the older paper without the signature orange fibers. I just bought one on sale for Dad's Mercury Grand Marquis for $3. >:^)

    As for the comments on synthetic oil, I'll post my responses in the appropriate thread.

    i just wanted to share the links with you guys, cause we all got into some heavy talk and theory about the related links the last few days. i personally enjoyed the debate, as i also feel i have met some new people that are civil and open minded as well.
    BTW, the links were posted for me in the silverado topic on the pickup board by my friends Obyone & Quadrunner500. they deserve the credit, and they are two of the best guys you will ever talk to.

    That's about as good an explanation on oil filters as I have ever seen. I think we have all

    Now which one is the best? he he
    Good Morning everyone
  • tsjaytsjay Member Posts: 4,591
    It's been a while since I posted anything about filter paper in general, so I thought I would toss this out in case anyone is interested.

    As I've told you before, we use a combination of several different cellulose fibers and some synthetics.

    The cellulose fibers are mostly wood pulp, but also in this category is cotton linters. This pulp is actually the fine cotton fibers from the cotton seed. The cotton seed oil mills remove this "hair" from the cotton seed prior to crushing the seeds to get the cotton seed oil. These fibers would otherwise soak up some of the oil and reduce the yield of the oil.

    Cotton linters are used much less frequently than they used to be because of their relatively high cost compared to wood fibers. They are very good fibers for filtration purposes.

    As for wood fibers, they really break down into two major categories: hardwoods and softwoods. In general, the hardwood fibers are much shorter and lower in diameter than the softwood fibers. We use the softwood fibers to give the sheet bulk and permeability, and the hardwoods are used to reduce pore size for efficiency of filtration.

    Our wood fibers come from literally all around the world. We get our nice big southern pine fibers from Florida, our nothern hardwood fibers from Canada, our Eucalyptus (hardwood) fiber from Brazil, some Scandanavian softwood from Sweden, and there's even a pulp we buy from Swaziland in Africa.

    This African pulp, believe it or not, is actually good old southern pine. Years ago, someone had the good idea that you might be able to transplant some US southern pine species to Swaziland, which is near the Equator, and, therefore, has a year-round growing season. The "crop rotation" is much shorter over there for these trees than it is in the southern US.

    The species of tree used to make the pulp is the major contributor to the differences in the various pulps we use, but the pulping process itself also has an effect on the fibers. Most of our pulps are produced in the "kraft" process.

    Some of our pulps are bleached and some are unbleached. The unbleached fibers are brown, but for automotive oil filters, where the paper isn't visible to the end user, who cares? Unbleached fibers are usually a little cheaper, since the bleaching process is skipped in the manufacture of this type of pulp.

    Later, Guys

    Hello everyone,

    I went though a few posts in this topic and was amazed to see how people here discuss and obviously know a lot about oils/filters.

    So I'll take the opportunity to ask the experts here a couple of questions. I don't know much about this topic so any pointers will be appreciated. Here it goes:

    1. I have 2001 Maxima. Driven rarely, and mostly on very short trips. I change the oil every 5K miles, and use Mobil 1 (5-30) since the break in period (1K miles). Is this often enough? Car doesn't burn any oil. Right now car is driven 5K miles in 6-7 months. Is that too long between oil changes?

    2. I also have a new Acura RSX-S. Car driven regularly 90 miles per day. One warm start in the morning (from a heated garage) and one cold start, normally, during the day. Manual says - change oil every 10K mils for normal conditions. Initial factory oil is not synthetic. Unlike my Maxima, I decided to follow the manual and wait for 10K miles before the first oil change. Is that too long? Also the car is high revving (up to 8K RPM) and burned 1QT of oil in the first 5K miles. Is that normal? I added a quart of Mobil 1 (5-30) to the factory non-synthetic oil. Is that ok?

    For anyone with any answer - thank you very much!
  • badrammanbadramman Member Posts: 61
    DO NOT mix synthetics with standard. They will separate and breakdown in the crankcase. The synthetic blends you see on the shelf have a "balancer" added to them so they mix correctly.
  • sgrd0qsgrd0q Member Posts: 398
    When you change the oil and switch from standard to synthetic, don't you have some oil stuck in the engine? So they'll get mixed anyway?
  • brorjacebrorjace Member Posts: 588
    badramman, That warning of yours is really overstated alarmism. As sgrdOq pointed out, each time you chamge your oil 10-20% of the old oil remains in the motor and you are essentially mixing them that way.

    Besides, all oils that are API certified HAVE TO BE compatible.

    But, this does not mean you should change often. Sticking with one brand/type is safest in the off chance that one oil's additive packages don't get along well with another.

    "the synthetic blends you see on the shelf have a "balancer" added"

    not accurate to my knowledge---a common mispeception!

    All API registered oils are compatable!

  • dmaverick1dmaverick1 Member Posts: 4
    I also just picked up an Acura Rsx type-s the other day, beautiful metallic blue, and my dealer recomended that I change the oil at around 3000km or 1900 miles because when the engine is new and breaking in, it creates more metallic particles wear than normal, and therefore doing an oil change earlier than scheduled is a good idea to remove all those excess metal particles sooner rather than later. I plan on switching to 5w-30 mobil 1 after the break in period. Can anyone suggest the best oil filter for the rsx type-s.
  • armtdmarmtdm Member Posts: 2,057
    the Maxima, 5000 is fine, I have owned a 95 and 98 went 12,000 between changes on them with great results. Even the short trips etc. 5000 between changes is fine, I have done that many times in different cars.

    Acura, I would go with a synthetic when you do change it. My current Buick has a indicator light, I did not go the full 7,500 (as suggested) the first time, changed to synthetic at 4400 analysis fine so I would not worry about it. Next change at 16,000 miles (oil will be in 12,000 miles) and I just changed the filter at the 6,000 miles (miles on the fitler or 10,500) mark.

    YOU Can mix dino and synthetics with no harmful effects.

    Where do these old wives tales come from????
  • spokanespokane Member Posts: 514
    You described the use of softwood and hardwood pulps, including eucalyptus pulp from the Amazon, for use in filter paper. Recognizing that wood pulp prices historically have huge price swings, sometimes within just a few weeks, are you able to keep you hardwood/softwood blend - and thus bulk, permeability, pore size, etc. - consistent from lot to lot?
  • tsjaytsjay Member Posts: 4,591
    Yes. We maintain the same furnishes regardless of the price swings. Some of our pulps are bought on contract, with the price fixed for a specified period of time. But, even if the price goes up, we maintain the furnish so that we have a consistent product.

    We have some fibers that can be directly substituted for others and some fiber combinations that can be substituted for a particular pulp, but this is to cover shortages, not to react to price changes.

  • brorjacebrorjace Member Posts: 588
    dmaverick: "I also just picked up an Acura Rsx type-s the other day ..."

    Nice car. If I was to buy a car tomorrow to replace my current Civic Coupe I'd be torn between an RSX Type-S and a Celica GT-S. But, I won't go into why I'm torn here and now ... >;^)

    "... and my dealer recommended that I change the oil at around 3000km or 1900 miles because when the engine is new and breaking in, it creates more metallic particles wear than normal, and therefore doing an oil change earlier than scheduled is a good idea to remove all those excess metal particles sooner rather than later."

    This is 'old school' thinking ... and there's a lot of solid common sense to it. A few years ago I would have agreed with it 100% ... but lately I've heard some Honda owners (and Ford owners) that have been told that their crankcase has been filled with a special break in oil at the factory. (see below) So, I'm a little reluctant to recommend EVERYONE do this.

    "I plan on switching to 5w-30 mobil 1 after the break in period. Can anyone suggest the best oil filter for the rsx type-s."

    Motor oil choice sounds fine. The factory OEM Honda filters come in two flavors (both are colored blue). The first is a made-in-USA Filtech filter which is very, very good and is probable the preferred filter for most Honda/Acura automobiles. The other filter which is replacing it is a made-in-Canada filter manufactured by Fram. I've chopped one for these apart and it appears to be Fram's typical (low) quality, cardboard end-caps and all. I'd avoid this one and choose something else.

    As far as aftermarket filters are concerned, Pure-One (Purolator's best), Baldwin, Hastings and Mobil1 are all very good. I've settled on Hastings because I've found a dealer who has them for $5 each (including S&H) along with some specialty automotive fluids I use. I usually like WIX (and its clones from NAPA and other sources) but the number for Hondas is rather small so I'd pick another instead.

    sgrd0q, I missed your questions the first time through. Some cars burn more oil during break-in than they will at any other time in their useful lives. So, some oil consumption at this point is normal. How much is normal? Well, the RSX 2.0 engine (even the block) is brand new so I don't know what it could be compared to. And of course, higher-RPMs are harder on oil and have to be factored into any oil consumption you might notice. Adding Mobil 1 to your crankcase during this time should be OK.

    Did you get a speech from the dealership about NOT changing your oil for the first few thousand miles (usually about 5,000 miles) because the car is filled with a special break-in oil? I've heard this from a few independent sources over the last year and a half for both Ford as well as Honda cars. Since I cannot see how the dealership can profit from turning away oil change customers, I'd tend to believe that this bit of advice is for real. Also, there was a bit about new Hondas being filled with a special, break-in oil on their factory website a while ago but they radically changed their site earlier this year and I have been unable to find the info since.

    --- Bror Jace
  • sgrd0qsgrd0q Member Posts: 398
    No - the dealer didn't tell me there was any special oil. The salesman told me there was no break in period for the RSX-S, and then told me to change the oil after 4K miles, "like any other car". I think he didn't know what he was talking about.

    The manual, however, recommends easy starts and stops for the first 600 miles. This is in the "Break-In" section. Also, in the same section it explicitly says the oil should not be changed before the first scheduled interval comes. Surprisingly, for normal driving conditions they recommend oil changes every 10K miles, and filter changes every 20K miles. (For extreme conditions they recommend 5K-oil and 10K-filter changes.)

    So after 5K miles I burnt 1qt, and added Mobil 1.

  • seeligseelig Member Posts: 590
    great to see someone in here that takes the time to give advice to others. on the subject of break-in oils, have you ever been aable to confirm what is in this oil that makes it special? this question has been banged on for quite some time on the pickup board, and none of us have ever found the answer to what makes this oil so special. there is a dye in it that we know of, and that apparently is to give the mechanic an easy way to find a leak, should that happen in the first few thousand miles. but when going to auto maker websites, and even emailing them, along with trying to buy the special break-in oil from the dealers, the results are nada. if you have any info that supports the break-in oil theory, would you please post your findings for us?
    thx
  • bidandsellbidandsell Member Posts: 43
    On my new Honda I did an oil analysis on the factory oil. Blackstone found extremely high Moly in it which they said they never saw in any other oil.
  • seeligseelig Member Posts: 590
    that the moly is from the prelube that is used for engine assembly, but why is it that the dealers don't have any. if it is so important for this "special" oil to remain in an engine for the recommended time, then what happens if a seal or oil pan gasket has to be replaced during this time? do they put "special" oil back in, or fresh oil like we use?
  • brorjacebrorjace Member Posts: 588
    Bidandsell, Moly, eh? Yes, I would agree that it's most likely from the engine assembly lube. This stuff is critical for bearings as well as cam lobes, etc ... when an engine is turned over for the very first time.

    sdr0q,
    I think the manual telling you NOT to change the oil before a certain time is a clue that they put a special oil in the crankcase at the factory ... but unfortunately, it's only a vague clue. Does Acura have a 800 number in your manual somewhere for Honda America? This would be a better, more definitive answer than anything you'll hear from a dealer ... even a good (non-sleazy) one.
    Either way, I'd use the "severe service" as a first change interval.

    Seelig,
    I used to haunt the use.net forums like rec.autos.Honda before "my-deja.com" was bought out by "Google.com" and I found a genuine tribologist there from North Jersey and we kicked around some theories as to what might be in a typical "break-in" oil. Even he wasn't sure. Theories ranged from a micro-polishing agent that would microscopically scour the cylinder liners allowing the rings to better mate to the walls as well as extra amounts of ZDDP in the oil to protect the metal while things were still very tight ... because the newer, SJ standard oils have less of this vital anti-wear compound.

    But, that's all they were, theories. We had no real clue as to what's in that stuff. Your idea of a dye is an interesting one, but you'd think that an oil leak on a brand new car would be pretty easy to spot, wouldn't you?

    The mystery continues, I gues ...

    --- Bror Jace
  • seeligseelig Member Posts: 590
    thank you for the courteous reply.......the dye thing is real, but like you say (and i agree) a leak should be obvious. we know for a fact that the silverado's all have a dye in the oil from the factory, but the "special" oil is a mystery.
    your micro polish theory is the best so far, but the engine builder would have to have the tight clearance dimensions on every moving part don't you think? otherwise there might be premature wear on parts that didn't need any of the lapping that other parts do. then again, any lapping compunds would be filtered out by the filter. would be nice if someone really knew the answer.
    thx
  • tboner1965tboner1965 Member Posts: 647
    But I've yet to read any engine overhaul instructions that say you have to purchase a special oil to break-in the newly rebuilt engine.

    I think Advanced Auto Parts "gives" you 5 quarts of Mobil 1 if you buy one of their reman'ed engines.

    I've not asked them, but wonder if you could request them to get you some of that break in oil. Or ask your dealer parts department.

    It seems reasonable that their might be they dye, and perhaps a mild friction compound in there. But who knows for sure?

    I've also heard there are more/less detergents in the first fill. Again, who knows for sure?

  • wtdwtd Member Posts: 96
    I see alot of people advocating changing synthetics at 5,000 miles and up. I wonder why than, when I had an oil analysis done on the Mobil 1 in my 98 truck that it came back with extremly high lead levels and most of the anti-wear additives were below normal. viscosity was also above normal showing the oil was starting to thicken. I only had 5,069 miles on this oil sample and it was mostly highway miles. I was also using an AC-Delco gold series filter. This truck only had 32,738 miles on it and has not been abused.

    My oil analysis has made me come to the conclusion that Mobil 1 cannot go much longer than conventional oils. I would bet that most of the other synthetics would be the same. Blackstone labs who did my analysis recommended dropping back to 4,000 mile changes and retesting.

    Are the people on here who advacate extending oil changes with synthetics, baseing their information on oil analysis or by manufactures's claims? I'm pretty disappointed in Mobil 1 right now and do not believe it is as good as it once was. I'm wondering if they went the route that Castrol did.
  • brorjacebrorjace Member Posts: 588
    I wonder how much of your oil analysis results have to do with the fact that Mobil 1 is formulated with such low amounts of additives like ZDDP to begin with? I wonder if Blackstone labs even figured this into their analysis?

    Think about it, the oil they USUALLY see is probably the 15W40 diesel heavy duty stuff that starts out at around 2% of ZDDP while Mobil 1 tri-synthetic starts out with about 0.75%. This might be why the level seemed awfully low to them.

    Try Valvoline Synpower Synthetic which has around 1.5% of ZDDP if you're unsure of the newer Mobil 1.

    The reason why new car engine builders don't spend extra time polishing the motor to the 9th degree is that it is too expensive. It's easier to get it to a certain (good) level and throw a friction modifier or whatever in the oil and let it break-in.

    --- Bror Jace
  • armtdmarmtdm Member Posts: 2,057
    I have done oil analysis on about 7 different cars over the years, no two engines are even remotely alike in the wear metals. Your engine may simply have a higher lead wear then others. If you think it is Mobil 1 change to another synthetic and see what the analyiss says at the same mileage. Your engien could simply break down oil more, cook it or whatever. The purpose of oil analysis is to see wha tis happenign and do oil changes based upon the results, which is exaclty what you are doing.
  • corvettecorvette Member Posts: 11,272
    Check the forums on VWVortex.com, in particular the 8v 2.0L forum. This is the base engine in the Golf, Jetta, and Beetle, and many owners are reporting high oil consumption (1 qt/1000 miles or higher), especially when the first oil change is done early (before 5,000 miles). The internal seals in this engine need the break-in oil for that period to seat properly.

    It might interest you to know that the oil change interval on that engine as well as the VR6 engine is: first change at 5,000, second at 10,000, then every 10,000 miles thereafter with regular oil. VW's official stance is that synthetic may be used if the owner so desires, but it isn't required. I don't know how long I will keep my Jetta, so I use synthetic oil at the normal interval (every 10k).
  • csandstecsandste Member Posts: 1,866
    I had posted this on the slippery slope discussion. I thought I'd copy it here because I think it might be a downside to extra high grade filtering papers. This is from the MiniMopar study. Obviously some of the contents of all of these filter studies are can be wrong, i.e. comments about fuzzy filtering media looking sub par when in reality that's what you want a filter to be.

    The comments about splitting may not be statistical, but like Toyota sludging they are troubling. Especially since the Champion Labs filter is made tougher and since other Champion Labs filters have no reports of these incidents.

    http://www.frankhunt.com/FRANK/corvette/articles/oilfilterstudy/oilfilterstudy.html
    "Mobil 1 M1-301
    Like the Champ filter, this filter is made by Champion Labs. However, it uses a unique end plate and a thicker can that make it the strongest filter available for wide distribution retail sale. It also uses a synthetic media,which inproves filtration and flow. I'm happy to say that this filter is NOT a fake. It is definitely a unique design. It uses a synthetic fiber element that can filter out very small particles
    and is very strong. It is rated just under the Purolator Pure One as far as filtering capability, but is still very much above conventional paper
    filters. It also has a very strong construction to withstand high pressure spikes during start-up. However, as with all Mobil 1 products, expect to
    pay 2 - 3 times as much for this filter.
    I have received many reports of these filters failing at high pressures. It seems that the seam where the backplate crimps to the case can split."
  • adc100adc100 Member Posts: 1,521
    I would trudt Mobil more than Blackstone. Their pre-Tri-Synthetic oil was capable of producing extremely low wear over 200K with 15K change intervals. I'm not gong to tell you that its better than Red Ling or Amsoil. But they aim to be the best and I don't believe they would let their product become less than the previous generation product. (they are not another Castrol)
  • tsjaytsjay Member Posts: 4,591
    No, "high density" (I suppose you mean media with small pores that trap the smaller particles)is not hard on the filter (couldn't cause the failure of the double seam of the base plate to the can, if that's what you mean).

    The paper could be totally clogged, and, if the by-pass valve in either the engine or in the filter itself, whichever the case may be, is working, then the worst effect of that would be unfiltered oil, not a catastrophic failure of the filter.

    Then why the reports of failure in Mobil filters, if the construction of the filter itself is reinforced by Champion Labs. Or is this just anecdotal?
  • zr2randozr2rando Member Posts: 391
    on the cartridge? Maybe they put the majority of the cost on the cartridge and are using slightly sub-quality cannister? Could also be that people are using them in the extended change interval which they SHOULD be intended for and maybe the hot/cold just finally gets to that crimp after so many cycles...I do the 3mo/3k thing so I really have never given ANY filter the opportunity to fail to temp stress problems, but I imagine the more often you push it the more often statistics catches up with you, even for premium filters...another good argument to change filters halfway through extended oil changes.
    If they leaked early on though, I doubt I would buy any more and write it off to VERY good advertising and not enough [non-permissible content removed] behind it.

    And it's a good day for ANY sports ain't it?
    Rando
  • csandstecsandste Member Posts: 1,866
    The filter test specifically says that the Mobil filter is built stronger than the others but still split, that's what I don't understand.

    Your comments about heating/cooling cycles in extended changes is interesting. Just like airliners become stressed after so many years.
  • tsjaytsjay Member Posts: 4,591
    If some Mobil 1 filters failed, it could have simply been a problem in the double-seam operation during manufacture. If the base plate and the shell are heavier gauge steel than ordinary filters, perhaps they are harder to double-seam. Maybe they are sealed by an entirely different process? I just suspect the problem was in the maufacuring process, even though the maker of those filters is as good as anyone in the business.

    In the filter report that individual said...

    "I have received many reports of these filters failing at high pressures. It seems that the seam where the backplate crimps to the case can split."

    We don't know the circumstances under which the failures occurred and have only second or third hand information that any failed at all. The guy doesn't say how many reports of failure he received and doesn't even say that he verified any of the complaints.

    In the AC Delco filter article a few posts back, it stated that when a filter blows up, it is never the filter's fault, because there should never be that kind of pressure in the filter unless something else failed, like the oil pump pressure relief valve.

    We just don't have enough facts here.

The filter is built like a Sherman Tank (550 psi burst pressure) There is a clam of 14-16 gpm flow and an efficiency 90%. Before you say anything- I believe a lot of this is advertising hype. My thought however is that the efficiency and high flow rate will make this filter suitable for at least a 8K+ oil change without a filter in between. I believe probably any filter is capable of doing this, I just like an extra margin.

    BTW I strongly recommend that if you own a GM product and use a PF-47 you upgrade up to the PF-52, which is almost 1 1/2 inches longer. And when you figure the entire 1 1/2 inches is extra length of filter media you get at least an increase of 50% filter area. So anong with everything else I also switched to the larger capacity filter. I looked very closely at the Pure One specs on page 929-930 of their (Pure One)filter application menu and eiher filter will work if the clearance is there. Again-I'm not claiming any breakthrough here-just information based on some most excellent discussions here- thanks.

    I agree with you about the mfg process being suspect if they have specifically made that a "heavy duty" componant (could easily be a problem with hot/cold expansion/contraction problem with that..looking back over the years I have had plenty of "heavy duty" items break or need regular maintenance just as easily as I thought "normal duty" items would have, the only difference was they were more expensive to fix/replace because of it. At $10 a pop, I would be calling them with any examples of failure that I had, and request some type of refund if it was actually a premature failure of any type,,there are too many $5-6 competitors to worry about it much though (or K&N as mentioned above), they don't own the market.
    The comment about a filter should hold it's own unless another componant causes failure is probably a good statement too, any internal bypass that does not bypass will be a filter killer, and would also cause leaks elsewhere as well which would indicate that the filter was just another victim of overpressure,,,but if it was only the filter...."hello, Mr Mobil1 do you have a minute?"

    I'm a Red Sox fan living in Yankee country so you can just imagine how I'm itchin' for the Yanks to get their butts handed to them ... even if I kinda like most of the individual players ... Roger Clemens excepted, of course. >;^)

    I put a K&N filter on my car ('95 Civic Coupe) and but I didn't like paying such a premium for such a small canister. That's my rational for not using a Mobil 1 filter either. Also, I did not find that welded-nut structure on the back of the K&N canister terribly helpful. Give me the standard, faceted end that a filter wrench can grip. >:^D

    BUT the K&N DOES flow more. I heard of Ford Contour SVT drivers preferring the K&N because the OEM Motorcraft filter starves the mtor for oil at high-RPM use because it is so restrictive. So, I'd believe their claims ... the ones about flow, anyway.

    Zr2rando, I generally like the WIX/NAPA filters but since I'm primarily a Honda man and the inner filter cartridge is rather small in #1334 (Honda part number) I generally avoid WIX/NAPA Gold (and Castrol and Penske ... same manufacturer even if they aren't identical) for Hondas ... but like 'em a lot for most other (domestic) applications. They are really, REALLY well made.

    Right now I've got a couple Hastings on my shelf (good size for Hondas) and I'll be sticking with them for a while ... especially since I get them for $5 each delivered to my door.

    Have you looked to try to find an oversize filter? I'm guessing that the chances are 99% one is available.

    Well, the LF-402 (I THINK that's the Hastings part number) is a really good size. I'm pleased.

    WIX has a #1344 which fits ... but I was told that the bypass filter opens at a much lower pressure than the #1334 and the larger (taller) filter rubs on part of the engine.

    Brorjace, you order the Hastings? I think they were the ones that years ago had cotton (depth media type) filters, who do you order from?
    I think I'm gonna try the Castrol plus for a couple and see how they look inside , the pf52 equivalent does not have a bypass in the filter and my trucks have the filter at a remote (always full of oil anyway so the antibackflow valve doesn't really matter either, guess I'm just checking the filter itself.

    You can probably find HAastings filters locally, not advertised much but specialty auto/truck shops stock them. Actually this site's HAstings filter prices are not bad.
