    "What is the oil capacity of the corvette ? I think it may need a lot because it is a high performance engine... ??"

    The manual calls for 6.5 qts. (with dry new filter)

    On the track, the video says you can put an extra quart (7.5 qt total) due to high lateral side loading which may induce an oil starvation condition at higher G load.

    When you guys run your synthetics, how often do you change filters? Do you trust the FRAM claim of 7k filter? If amsoil is so great why isn't everyone using it at least in newer cars? And for fun, consider my 87 volvo, so far as i know has used only "dino" with now 256K, 175 in each of its four little cylinders. Thanks for considering these questions. 58VW (yes we had one)

    I do oil filter changes when I do oil changes. FRAM has a mixed reputation. But over time (14 years) I ran FRAM PH8A filters in Toyota Landcruisers, one of which went app 250k miles and that was with 15k interval oil and filter changes. This one was dealer serviced and the valve covers were taken off every 15k for valve adjustment. The mechanics always reported (17 times) very clean innards. :) Mobil One 5w-30 and 10w30 when 5w-30 was not available.

    I run 12,000 miles intervals on one car with Amsoil. Based upon my results of the past few years I have gone from changing the filter at 6000 miles to just leaving it on. It didn't make any difference in the oil analysis. So, I just run the same oil and filter for the 12,000. I have come to the conclusion that fitlers are pretty much uselss in todays engines and todays oils, they capture very little in the way of wear metals and dirt and flow is more important then filtering ability IMO. So, I am switching slowly to all K&N filters for the flow. Currently using Amsoil filters.
  • ruking1ruking1 Member Posts: 19,826
    Yes, I don't know if oil filters are on topic but seem very hand in glove to me! First of all whether you use conventional or synthetic the best filter system is 1. bypass 2. normal 3. preoiler.

    Much of the wear (half and above) in todays engines are unmitigated, which can be mitigated by preoilers. Synthetic really only mitigates part of the wear, but over the course of an engines useful life can be significant.
  • pulgopulgo Member Posts: 400
    IMHO a preoiler only makes sense in a commercial vehicle or if you plan on keeping your car/truck for 300k miles/10 years or longer.

    An installed bypass system is US$ 500 or more, a preoiler in most cases closer to US$ 1000.

    I have an Amsoil dual filter bypass system on my 2001 Echo and after inquiring about the installed cost of a preoiler it seems cheaper to install a good used engine if and when the engine fails, probably not before 300k miles.

    On a tractor trailer costing US$ 100000 a preoiler seems like a minor investment and worth doing. For the general public it seems a waste of money unless done just for the heck of it.

    While I do not doubt that the products you cite cost what they cost, the fact of the matter is here are two references with the aftermarket prices quoted. I am mindful of the fact that oem vehicle manufacturers want their product to last a long time but as you have pointed out NOT that LONG. The goal is to sell product be it new cars every year or oil changes every 3k or less. :(:)

    So really the aftermarket costs can be way lower if there significant demand for them.

    Many of us are bicycle enthusiasts. I've ridden
    bicycles for over 60 years. (They're one of the
    very best forms of exercise, and I try to ride
    about 2,000 miles a year.)

    Anyway, to the point....chains and sprockets:

    Other synthetics may do as well, but Amsoil 75-90
    used for chain lube is EXCELLENT !

    Bike shops sell lots of high-priced chain lubes,
    and I've found the Amsoil beats them about three
    times over.

    If you love bicycling, you'll love Amsoil for
    your bike.
  • ruking1ruking1 Member Posts: 19,826
    The 75-90 is the synthetic gear lube that you speak? (for use in differentials?)
  • chispaschispas Member Posts: 94
    Yes, I probably have a spare gallon of 75 - 90
    kept at all times to use for its intended purpose.

    One day, about 20 years ago, I said, why not use
    it for chain lube....

    (Realize that a bicycle chain life varies in quality and what kind of environment it is used in.)

    My statement that Amsoil "gear lube" makes a
    most excellent chain lube came about because I
    simply decided to try it.

    Was just passing along something. Try it !
  • ruking1ruking1 Member Posts: 19,826
    Yes I will, I have the Mobil One 75w-90! But I think just a different brand for chain lube purposes! :)

    BYE !!!
  • chispaschispas Member Posts: 94
    Bye !!!

    Before I go, when was the last time you threw a
    leg over a bike ?

    If you really ride, how many miles / year ??
  • chispaschispas Member Posts: 94
    I had a '76 Maverick with 200 c.i. six...

    Broke it in on Mobil l and kept it up for 86,000...

    The front harmonic balancer seal started leaking...

    When I tore it down, the seal was hard as a rock..

    Had to go to the Ford dealership and buy a new
    harmonic balancer because it was "cut" too
    deaply...

    Other cars/trucks I operated at that time were
    on Amsoil...

    Go ahead, say I didn't give Mobil 1 a good test.
    I did. It hardened that seal...

    Amsoil has never done that for me.
  • ruking1ruking1 Member Posts: 19,826
    For me, it is hard to go wrong with Redline, Amsoil, Mobil One! (Group Four)

    "Before I go, when was the last time you threw a
    leg over a bike ?

    If you really ride, how many miles / year ??"

    I don't really ride a lot! I would guess NTE 3700 per year.
  • shiposhipo Member Posts: 9,148
    ... to say that 1976 vintage Mobil-1 (or Amsoil) is the same as 2004 vintage Mobil-1 (or Amsoil) is like saying the 200 cid six in the Maverick is the same as the 3.0L Duratec V6 in the Taurus.

    It just ain't so.

    Best Regards,
    Shipo

    Just the kind of comment I'd expect...

    A damned lie !!
  • joatmonjoatmon Member Posts: 315
    ruking and I have had a few differences, but he is a long-time, well informed poster.

    We can debate here, but that sort of accusation is out of line.

    Jack
  • chispaschispas Member Posts: 94
    I agree !

    My APOLOGY !!

    Sort'a strange how worked-up people get about
    this subject...

    ALL I was trying to say was use a synthetic gear
    lube for chain lube...

    Geesh !!!
  • ruking1ruking1 Member Posts: 19,826
    I was agreeing with you!??? Are you dealing with issues that I am unaware? :(

    Currently, I used Mobil One 5w30 on my chains. To keep them clean, I shoot them with Simple Green or a like product and for those stubborn luggies, use an old nylon tooth brush. 75w-90 sounds pretty good and will probably not add any significant effort. So again since I have Mobil One 75w90 on hand I just go from one bottle to the other. :)

    WOW! That sounds a LOT to me! Unless you live in a warm climate and ride it year round!

    Perhaps you should be a contributor to UBI....

    This is off-topic, but UBI stands for United
    Bicycle Institute....

    Lots of people ask questions, and I've given
    advice....

    Perhaps you'd like to join in the discussions :

    Actually when I was on a county transportation board, I was able to give the bicycle advocates pretty widespread support. One of my fellow transportation board members I served with is a legendary bicycle advocate in these parts. :)

    I've tried to use Amsoil synthetic greases for
    bottom brackets and head bearings, and they
    FAILED...

    Bicycles are VERY hard on bearings, for example,
    at every tear-down for routine clean and lube,
    the bearings should be replaced, not re-used....

    Why ? Because ball bearings microscopicly elongate. They're not perfectly round after any
    use at all...

    Bicycles are extremely hard on bearings and the
    kind of lube used....

    Hi-temp automotive grease for disc brake wheel
    bearings is the "ticket", and petroleum based
    seems the best....

    Haven't ever figured out why ???
  • ruking1ruking1 Member Posts: 19,826
    You know all I can say is that if it works, IT WORKS!
  • chispaschispas Member Posts: 94
    "You know all I can say is that if it works, IT WORKS!"

    Just my home-baked idea, but, it seems like
    synthetic greases don't have the "shock-absorber"
    ability that petroleum provides.

    Big disappointment....didn't ever want to admit
    that synthetics were inferior in some kind'a way.
  • chispaschispas Member Posts: 94
    Let's be friends...O.K...??

    One thing the Amsoil dealer told me, I won't
    forget, the base stock for Amsoil is ester,
    produced from alcohol.

    He described if you'd drop a rubber band into a
    glass of alcohol, the robber band would soften
    and practically dissolve.

    That's how he explained why my gaskets and seals
    never gave any trouble, but petroleum based oils
    tend to harden and shrink them.

    Made sense...

    This is over on the Town Hall "Oil Change Fiasco"
    thread....

    (Just an example, I'm simply trying to "help",
    and am not here to get into any kind of arguments.)

    ______________________________________________

    "I thought Jiffy Lube had to buy from Pennzoil"

    I've used Pennzoil chassis lube for lots of years.

    Was helping a friend last summer change-out the
    ball joints on his old Lincoln. From the color
    of the grease around the grease fittings I could
    tell that his car was using something like the
    cheapest Pennzoil.

    I asked him, where do you get your car greased ?

    He said Jiffy Lube.

    So, I asked, did you know that Jiffy Lube uses
    the cheapest Pennzoil greases, there are much
    better that Pennzoil makes, but they have to use
    what Pennzoil "tells them to" ?

    He said, "I didn't know that."

    "Well, now you know."

    I wish they'd stop using the term "dino" oil---oil comes from plants not dinsaurs. I know, switch to decaf Shiftright--lol!
  • highenderhighender Member Posts: 1,358
    you are right.......

    maybe a very small percentage of the hydrocarbons come from dino flesh....

    but it does denote the time line/origen

    how about lets try to figure out a new, better term, and keep using it....and perhaps in a few years it will be listed in websters..... seriously...... !

    websters added 20,000 new meanings last year, and took away a few too....some words too archaic or obtuse that nobody living is using it... :-)

  • malachymalachy Member Posts: 17
    Yesterday I changed the oil on my 2004 Hyundai. I chose to use Mobil 1 based on all the positings. I could not go with the Amsoil. If the stuff is so great, why don't I find it in stores? I am afraid it will void may warranty if Hyundai goes looking for a reason to shaft me!

    I would be tempted to use it on my 97 Golf. Will I hose my engine (78k) if I convert this late in the game?
  • chispaschispas Member Posts: 94
    I know you mean well....

    Amsoil (because of its base stock) can actually
    swell gaskets and seals....

    Stop leaks....

    I've proven it in old junkers...

    Keep on "preachn'" ....
  • highenderhighender Member Posts: 1,358
    do you think AMsoil will be better for my SUburban 5.7 V8 vortec engine...with 16,000 miles on it ?? I thought of changing to synthetic oil at the next oil change.

    any body else have any feedback ???

    thanks .
  • chispaschispas Member Posts: 94
    Those synthetic oil studies at the above site :

    http://neptune.spacebears.com/cars/stories/oil-life.html

    Will give both of us a lot of information.

    I have no idea what the final conclusions will
    be.

    Let's stay "open minded".
  • joatmonjoatmon Member Posts: 315
    Vortecs seem to throw out lots of Copper (and Iron). Therefore, I wouldn't use a synthetic looking for a longer drain, unless you go to a bypass filter setup.

    My advice, use Pennzoil every 4k or so, or Schaeffer's or Castrol blend every 5 or 6k.

    The spacebears test added lots of fresh oil between the change interval which means that the results may not relate to your situation if you're not using a lot of oil between changes.

    GM dealers sell Delco UPF-44 filters that seem to have great filtering ability and great flow, a tough combination to find.

    BTW, w/ a 5.7, I guess your Suburban is at least 5 years old. And 16k on it?

    Of course, you should change oil/filter at least once a year regardless of mileage.

    Happy Motoring,

    Jack

    I would not have any concerns with Redline, Amsoil or Mobil One. Mobil One 5w30 is the OEM fill for my Chevy 5.7 L V-8. 385 hp/torque. I have been doing 15k intervals with (AC Delco PF44 oil filters, picked up an armful at the Daly City, CA, KMart :)) since app 1k miles and now have INXS of 57k. :)
  • csandstecsandste Member Posts: 1,866
    I use Wal-Mart house brand in my Hyundai. I change at 4000 mile intervals. If I went to a synthetic I'd stretch it out to 6K with a group III or 7500 with a PAO. I've had nearly thirty cars during my driving career and oil failures may account for three deaths, early trades. And that's a stretch--oil leaks with a Plymouth Arrow, oil seals with the infamous Mitsu. 3 liter six in a Caravan--same thing happens with any oil--crappy engine, and a mid-sixties Corvair that kept throwing belts. I also bought an 88 Festiva that had 28K on the car. Bet the guy changed oil once. Ran it out to 110K and swapped in a used engine ($600 with new clutch)--still going strong when the brakes needed major repair at 160K-- the synchros were beginning to go so I donated the car. Still wish I'd hung onto it.

    All the rest of the cars had non-engine related problems that caused me to unload 'em. Sloppy front ends, major brake jobs, transmission failures, etc.

    Lessons-- Some people go nuts over oil worrying about oil, lots of people abuse their cars by never changing it. Most cars engines given a 4K change cycle with any SL oil will last a lot longer than the cars that surround them.
  • ahlinahlin Member Posts: 30
    How many months can I go with this oil? Should I change at 6 months even if I only have about 5000 miles? Am wondering about how long you can go when you have not reached the 7500 mile mark?
  • chispaschispas Member Posts: 94
    You may consider calling Amsoil in Wisconsin for
    their advice.

    Their number that I use for ordering is :

    1-800-956-5695

    I'm sure they can transfer your call to someone
    in customer service.

    (I'm currently using the Amsoil 5 - 30 that is
    recommended for 25,000 miles or up to one year.)
  • chispaschispas Member Posts: 94
    For some reason that I'll never know, my last
    purchase of Amsoil products caused their accounting department in Superior, Wisconsin to call me.

    They politely informed me that my bank had returned their charge against my ATM card.

    I inquired "Why?"

    They said, "There was no reason given."

    I had already received the products, and here was
    Amsoil trying to get payment.

    But they were VERY polite.

    I asked, "Give me instructions, and I'll mail a
    check today."

    As soon as that check and some others cleared,
    I moved to another bank. I'd had some other
    problems at the bank about that same time.

    This little "episode" was handled very well by
    Amsoil.

    UPS saves me going to Wal-Mart....

    Standing in some of their checkout lines, sometimes for an hour, is a "pain".

    I pick up the phone, spend about 3 minutes,
    and bingo. Five or six days later, here
    comes UPS.

    Love it

    For chainsaws and line trimmers, I've been using
    the Amsoil 100 to 1 2-cycle oil for over 10 years.

    This mix cuts down considerably on "blue smoke" that 2-cycle engines throw out. (Don't have to
    smell as much oil "stink".)

    If anyone has used Amsoil 100 to 1 vs. some other
    similar oil, I'd be interested in hearing their
    comparisons. Particularly if another brand
    reduces "blue smoke" better than Amsoil.
  • chispaschispas Member Posts: 94
    Anyone using this should be warned....

    The spark plug deposits will be a BRICK RED !!...

    I've never seen this before...

    So, I showed the mechanic at my local small engine
    repair shop what a strange color....

    He laughed, "Yes, there are some oils that contain
    an additive that will cause that bright red color."

    If you look at this chart, there WON'T be anything
    that will cover such a "brick red"....

    As quoted several posts above:
    "Vortecs seem to throw out lots of Copper (and Iron). Therefore, I wouldn't use a synthetic looking for a longer drain, unless you go to a bypass filter setup."

    The wear metals, in all probability, will be way to small in size to cause any additional wear. they certainly are too small to be captured by a full flow filter and as the engine breaks in these wear metals gradually decrease as well. I have a GM that throws off lots of copper too but over the first 50,000 miles it has decreased dramatically and I go 12,000 mile oil change intervals. From 400 ppm at first change to under 75 ppm now with the same interval. it is primarily dirt that causes wear.

    I recently purchased a used 2003 Econoline E350 12-passenger van, and the manual recommends 5W-20 oil. Does this seem like a very narrow range? We had a 1996 Ford 15-passenger van previously, before it was totalled, and its manual specified 5W-30 oil, which sounds more reasonable. I have been using Mobil 1 5W-30 in my '98 Passat, and was going to use Mobil 1 in the van. Would there be a problem if I used 5W-30 in the van ? Thanks.
