    Has anyone heard of Red Line synthetic lubricants?
    I have been using them in my Legacy for the past three years. Are they a good oil? Also, are synthetics all that much better than standard oil? I drive a lot of miles everyday, and they are almost all highway miles. I change the oil and filter every 3000 to 4000 miles, and take very good care of my vehicle. So is it worth it? I like to think that I am helping to preserve the life of my engine by doing so. Any reply would be appreciated.

    If you will do a Search (on left) for "oil", you'll find lots of topics to look through. Some have a lot of discussion on synthetics versus standard oils.

    I see a new product at Pep Boys- Petromoly oil additive. It seems Moly has found a way to keep those particles suspended indefinately... I read an EPA study that showed improvement in gas mileage and emissions. Anyone tried it?
  • ccotenjccotenj Member Posts: 610
    in the engine oil topic too... so i'll respond here as well...
    said it before, i'll say it again...
    if all these various additives really worked, the major oil manufacturers would put them in their addpack and advertise the heck out of it... the fact that they don't should tell you something...

    Stay away from additives. Various independent lab studies have shown that none of them offer any significant benefits. In fact, Slick 50, Duralube, and Prolong are all currently involved in law suites over their products.

    What lubricants offer the best protection for your engine? Full synthetics do. Mainly because they flow better in cold temps, and they maintain their viscosity better in extremely high temps, unlike conentional and synthetic blends do. Stay away from synthetic blends also. None of them contain more than 10% synthetic, so no significant benefit is obtained. You can also run full synthetics longer between oil changes than conventional oils. If you change your conventional oil at 3K, you can run a full synthetic for 5 or 6K, if a good quality oil filter is used.

    What's the best oil filters? Recent testing showed that the Mobile 1 and Purilator Pure One were ranked as the best, respectively. And for all those years I'd been using Fram filters. You guessed it, the experts said that Fram filters are garbage.

    So, I've stopped using prolong, Fram filters, and I've started using a full synthetic motor oil, and Mobile 1 oil filters. We'll see.
  • markbuckmarkbuck Member Posts: 1,021
    Where did you learn that syn blends are not more than 10% synth? I haven't seen definative info anywhere.
  • bottgersbottgers Member Posts: 2,030
    You would ask me that. I read it on the internet somewhere. I'll see if I can find that site again and I'll post the address here.

    To Subrunut,
    Red Line Synthetic oils have been widely used in Racing Engines. Suppose to be a good product, but I have never used them.
    For the miles between changes, I'd say "overkill"! I drive excessive highway miles in upstate New York (Snow and Ice in the winter, and dust in the summer), run synthetic oil and change every 10,000 miles. Have a 4 year old car with 116,000 and have done nothing to motor yet. I think you have to balance the type of driving, condition of driving and miles between changes.
    If you change you oil with a good quality oil and filter every 3000 miles you should go and go and go with no problems without the synthetic.
    BUT, seeing you have already running it, and have been for 3 years I would hesitate in switching. I seen switching cause consumption increase along with other problems. Maybe you should consider increasing to 6 or 7 thousand between changes. Hope I haven't confused you with my rambling.

    Several months ago I posted a comment on the positive results I was receiving from Prolong. I continue to receive those results in my pick-up. In October I bought a new Ford ZX2, 5-speed for a commute car. After a few thousand miles I replaced the oil and filter and added 10oz. of a metal conditioner called Militec per their instructions. I have to say the positive results in terms of engine smoothness, quickness to start and reductions in engine noise especially on the freeway, have been impressive. The ZX2 is "short" geared, that is at 70 the engine is turning 3200 rpm because of the low (or short) gearing. Prior to the Militec, the engine produced a "booming" sound at 70 that wasn't present at 65 or 75, just 70. After the Militec, the sound almost completely disappeared. Militec's advertising says a treatment is good for 15K. So, I'll see how it lasts. I'll post more information later this year.

    Check out the AMS oil site. If Truckers and (BIG ) Fam tractors use AMS synthetic. Good enough for me.
    One trucker went 300,000 on one yes one oil change.

    So you really want to know about Slick 50, ProLong, Duralube, etc.? Do you find it interesting that the oil-additive companies like to use lots of testimonials but very few facts ("my Ford Whatever went xxx,xxx miles and I never had to change the oil... thank you Product X")? Sick of seeing the words "tested by an independent laboratory"; and then they never mention the name of the so-called "independent" laboratory?

    Then read what well-known and identifiable expert sources, including independent research laboratories, state universities, major engine manufacturers, and even NASA have to say about them. Follow this link to find out more:

    Don't worry, it's a personal web page. The guy's not trying to sell you anything (and neither am I). Just trying to get the educated word out about PTFE and zinc-based oil additives.
  • guitarzanguitarzan Member Posts: 873
    Yes, that is a great article from "Road Rider that I like to refer to. It basically refutes all the claims of the Snake Oil people.

    I saw petromoly at PEP boys next to Slick50 etc. Their web site www.petromoly.com has an article that references an EPA study that had some positive conclusions. Its the only oil additive that has had the EPA review its effectiveness as far as I know (thats what they say). I don't use it, but I might try it if I had a car that was not passing emmission inspection, etc.
  • nismoskylinenismoskyline Member Posts: 6
    Just out of curiosity I went to the EPA (web site) and checked. As expected (and like most other snake oil salesmen) the PetroMoly claims are based on a very thin bit of truth, followed by a much greater dose of fanfare (i.e.--BS).

    First off, the product tested was not the additive, but their HP 5W-30 motor oil. In the very short term test (the only one conducted), statistically-significant emissions levels actually went up, not down.

    Incidentally, here's a quote from the first paragraph of the EPA report: "The testing reported herein was volunteered and paid for by Worldwide PetroMoly Corporation."

    Hmmm... go check out the above snake oil link. I think you'll find it an interesting read.
  • ccotenjccotenj Member Posts: 610
    someone finally found that link and posted it...

    one more time...

    if any of this stuff worked, the major oil manufacturers would put it in their add-pack and advertise the heck out of it. the very fact that they don't should tell people something.

    as far as the independent labs, if you look close enough at all their studies, you'll see that they are funded similarly to the epa one listed above.

  • bottgersbottgers Member Posts: 2,030
    If you're not using a full synthetic motor oil, you're not giving your engine the best possible protection. When compared to conventionals or synthetic blends, full synthetic flows better when cold, maintains its lubrication qualities better at high temperatures, and is less suseptible to combustion contaminents (carbon deposits). If you change your conventional oil and filter at 3,000 to 5,000 miles, you can go 6,000 to 10,000 miles between changes using full synthetics. You can definately save money using conventionals, but if you want the best, use a full synthetic.
  • ccotenjccotenj Member Posts: 610
    bob, sometime buy a quart of mobil 1 and a quart of dino of the same weight.

    pour it out.

    tell me you don't see a difference in how it flows. and it flows just as good after it's old. first time i poured a quart of 15-50 out of a mobil 1 bottle, it sold me.

    -Chris
  • marsha7marsha7 Member Posts: 3,703
    Folks, I do not dispute your claims at all, but I do admit to some (some?) old fashioned prejudice when it comes to engine lubricants. Somehow, being stuck in the past, like I am, I just find it hard to believe that anything but REAL oil will lubricate as well as, ...real oil. As my uncle used to say, he would use synthetic when there is no more coming from the ground. I hate to be stubborn or stupid, but I kind of feel that way myself. In terms of cold pouring, most of the time I use 5W-30. In Georgia, the 5 weight is thin enough for a cold engine, and 30 weight is thick enough for a hot engine. Sure, 50 weight is great for a hot engine, but 30 weight will do the job as well. The bottom line is, IMHO, not oil so much as regular oil CHANGES, to clean the junk out of the engine.

    I think I learned from some of my engineering classes that syntethic oil is FAR SUPERIOR than conventional oil HOWEVER, synthetic oil was designed for harsher operating conditions than automobiles so its debatable that you even really utilize the superior lubricating power of synthetic oil. You're better off sticking with conventional. Especially if you look at this in terms of cost. How much extra do you gain by paying extra for synthetic? Not much.
  • bottgersbottgers Member Posts: 2,030
    It depends if you're looking to get 100,000 miles out of your engine or 300,000 or 400,000 miles. Then it makes a huge difference.
  • johnyoojohnyoo Member Posts: 18
    I think with synthetics v. conventional oils you can look at it like this:
    Let synthetics=top of the line $6000 computer
    conventionals=Pentium II

    Let automobiles=normal user of computers(just checking e-mail, word processing, spreadsheets)

    The normal user can use the Pentium II or the $6000 computer, but how much of the $6000 computer's power is that normal user really going to use if you assume that the normal user doesn't change his behavior?

    Same w/ synthetics, how much of the extra lubricating power of synthetics do you really use in automobiles?

    I must admit though that I don't have any hard scientific data to support my point(i.e. wear and tear comparisons from conventional v. synthetics)

    I wonder if synthetic oils provide a placebo effect... How much wear and tear do you REALLY save over say 300,000 miles if you use a good quality filter and conventional oil compared with using that filter and synthetic throughout that 300,000 miles? If this difference isn't much then obviously conventional oils win out based on cost.

    If anyone does have more hard data on this I'd love to see it. I've been learning a lot from this topic so thanks!
  • ccotenjccotenj Member Posts: 610
    invalid analogy.

    i agree that most people never use their p-iii to it's capabilities. 99% of the time, the processor just sits there, waiting for something to do.

    but syn isn't like that. it's not sitting there, waiting to use it's capabilities. it's using them all the time.

    i've seen enough pictures of the insides of engines that used syn vs. dino to convince me. it's not just wear and tear. it's sludge buildup, etc. too. there's more than one factor involved.

    but it's a personal judgment call. you use what you feel comfortable with. frankly, i'm not using it so my engine will go 300K, since i get the "new car jones" before i ever get that far. i'm using it so that i get past the 50-100K mark, that engines like to expire in as well (personal experience there).

    -Chris
  • johnyoojohnyoo Member Posts: 18
    good point about syns working continuously.

    Obviously most analogies aren't supposed to be completely true. That's why it's "analogous" and not "identical. The only reason I focused on wear and tear was that most things I've read seem to focus on syns reducing wear and tear.

    There are definitely a lot of factors involved. I recently got a new car, (I guess it's already been 9 months!) so I'm trying to learn more about this area.

    I'm about to graduate college and start the process to becoming a professional engineer and if I learned anything it's that there isn't one right answer to most things. I think I've become less skeptical of synthetic oils from what I've been learning recently but I think until I start making more money I'll have to stick with changing my oil regularly! Thanks
  • 0patience0patience Member Posts: 1,712
    OK,after many oil analysis from engines that have run both organic and synthetic oils,there is some(very small) advantage to sythetics,but there are many drawbacks to synthetics,too.The main one is,if an engine has a minor leak,with a synthetic oil,it will become bigger(it flows out faster).If you would like more info on oil analysis,CAT has a oil anaysis program called SOS and they do extensive research and testing of oils.
  • marsha7marsha7 Member Posts: 3,703
    If I may followup on your comment about sludge buildup...

    I change oil every 4000 miles, and a new filter everytime. As I previously stated (maybe in another topic...hard to keep up) when my valve covers were removed at 165000, the cylinder head surfaces were clean as new, no sludge at all. However, to be intellectually honest, I never saw the inside of my cylinders, just the top of my heads. I am hoping my Y2K Intrepid will last at least 200000 miles. At 28000 miles yearly, and a 5 yr lease, it better last at least 140000 or it will not last until the final payment. Don't even talk to me about residual...LOL

    I have a 8 month old Toyota Solara and I have been religous about changing the oil at the proper times. About a year ago I was up late and saw an infomercial about Dura Lube and I have to admit it looked good. So I have purchase a quart to add at my next oil change. I am new to this post and I have read all 134 post and not too many of them even mention Dura Lube. Is that because it's a good product or not too many people have ever used it. Now as we all know, the oil companies are cooperating with the car manufactures because 50+ miles to the gallon engines have been around for years. Why are they not on the market because with prices how they are now many of us would be interested. Maybe the same reason car manufactures aren't attaching Dura Lube, Slick 50, etc. to their cars. Because oil companies would start losing money to synthetic chemical companies. Maybe I am way off base but it's just my two cents.
  • spnxspnx Member Posts: 37
    That's ok. You can redeem yourself by not putting Duralube in your engine ;-)

  • spokanespokane Member Posts: 514
    I can't criticize Dura-Lube but I find no reason to take either their ads or the 50-mpg conspiracy story too seriously.

    The Toyota Solara is an outstanding car. Its engine should hold up very well with regular oil/filter changes and normal periodic servicing of the cooling system. If you are prepared to spend something extra on assuring long life of the internal engine parts, suggest you consider the use of synthetic oil. Good luck.
  • ccotenjccotenj Member Posts: 610
    myself... but here goes again...

    if any of the additives worked, the major oil companies would put it in their add packs and advertise the heck out of it. every study that's ever been done that looks on this stuff positively has been funded by the manufacturer of the stuff. many independent studies have been done that point out the damage it does.

    as far as conspiracies... "as we all know"... ummm... given the cutthroatness of the car biz... you've been watching too much x-files... paranoia is a bad thing... you can get a 50+mpg gallon car now if you'd like to drive a geo metro...

    -Chris
  • phelpsmphelpsm Member Posts: 21
    Watch getting a little rough with the comments... I am not criticizing anyone who doesn't want to use an additive, I don't know if they work or not, that's why I am here. And trust me, I am trying to do as much research as possible before I make my decision. But I honestly haven't seen too many posts that give more than just an opinion on whether they work or not. I have done a lot of research on the Internet and still I haven't found an overwhelming amount of articles that say that the additives are harmful. Actually I have found as many personal statements saying they work as I have found that say they are harmful. The money for the additive is not my concern (if it doesn't work) but I am concerned if at 100,000 miles I am going to have to get my engine majorly worked on. If anyone has any information about engine damage please post it.

    Oh, on a personal side… I am not paranoid… I do not watch the X-Files… I do not believe everything I see or hear (that's why I am doing the research)… But I do believe that many companies (including car manufacturers) will not make alliances with certain products or companies because of the fear of stepping on the toes of companies they are currently already in good relations with. Attaching an additive brand to their cars could earn them a few dollars, but upsetting the car manufacturer/oil industry relationship could cost them more money in the long run.

    I did find a very interesting article on the expected future of engine lubricants (partially supports my opinion, partially goes against it, take it for what it's worth) http://www.total.com/us/cahier/lubrifiant.html

    and, if you double post - delete the second post yourself...
  • bottgersbottgers Member Posts: 2,030
    The best thing you can do for your engine is to not use any additives, and use nothing but full synthetic motor oil. The most you'll get from any additive is no engine damage. None of them offer any benefits, whatsoever. Anything you read stating that these products will offer any kind of benefits will be printed by the companies that make them, or by people who think they're getting some kind of benny from them. I doubt if any of these people could prove that they're actually getting any bennies. Stay away from additives and use nothing but full synthetic. You won't be sorry.
  • ccotenjccotenj Member Posts: 610
    if you scroll up a little through this thread, you will find a link that will link you to some INDEPENDENT research on additives. i would suggest you read that. you will also read several posts that point out that the research that shows the "benefits" of these products is funded by the manufacturers of these products (as bottgers pointed out).

    use full syn. stay away from additives.

    i don't know what "car manufacturer/oil company" relationship (or conspiracy, as it was earlier referred to) you are talking about. i've seen many interesting theories proposed and advanced on message boards but this one is new to me. perhaps you'd care to enlighten me?

    and (in relation to the above), what would the oil companies have to lose in putting it in their addpack if it really worked? c'mon.

    you asked for an opinion, you got it. you also advanced a somewhat questionable "conspiracy theory" and said "we all know..." associated with it. you got a response to that as well. sorry if it offended you.

    -Chris
  • phelpsmphelpsm Member Posts: 21
    The only direct "independent" research I found was at this site: http://www.geocities.com/MotorCity/2195/snakeoil.html

    I have read the entire article and I agree, it sounds like the additives may be useless in engines and could possibly clog up a filter. I do agree with it and I most likely will just use a good synthetic (Thanks all for the advice).

    But I am going to play devils advocate just a bit. If I just came up with a new product that sounded like it had outrageous benefits, no one would buy it with out some sort of "proof". Now I bet I wouldn't have outside researchers beating down my door to do the research for me so I would probably have to pay someone to do it for me. Could I persuade them to skew the results? Possibly. But could they also give the results they felt were correct? Possibly. The link I put above is the only study I have found (on this site and throughout the Internet) and I would love it if I could get my hands on other studies. Also the study mentioned above was done in 1992. DuraLube was not mentioned in the study and I don't know if it was even out then. But 8 years is a long time for possible advancements and so I didn't know if there were any "good" engine additives out there. That was my whole point for asking the question at the start.

    And the word "conspiracy" was never used by me. I'll agree I used "as we all know" and that was my fault for saying that because it was incorrect.

    And Sorry about the oil company/car manufacturer ideas, it's just my opinion. I do have a few links that talk about how closely the two work together. Once again, take it for what it's worth.

    http://www.gasandoil.com/goc/news/nte82608.htm
    http://www.purvingertz.com/ogj071299.html
    Most of these articles are rather lengthy (like this post and I apologize for that) but they mainly talk about how the two groups are working together to lower pollution levels. Now this has nothing to do with additives but it does show how close the two groups are. That's all my earlier post was mean to say. I also have more articles if people are interested.

  • bottgersbottgers Member Posts: 2,030
    The slickest thing about any additive is their marketing. Right now, Prolong has the slickest marking strategy, and just by coincidence, they happen to be the the most recent company to come up with a new additive. Hmmmmmmmm......
  • ccotenjccotenj Member Posts: 610
    first, sorry for attributing the conspiracy word to you. i picked it out of the wrong post, and i apologize.

    that being said...

    if they are working together to reduce pollution levels, it's kinda counterintuitive that they would be withholding an engine that got greater mpg.

    in the business world, many disparate groups work together towards a common goal (like in this example, lower pollution levels). that doesn't preclude them from making other alliances to make a buck. as a general matter of fact, they would. they have a responsibility to their shareholders (no altruism there, the ceo wants to keep his job). also, if 2 groups are shutting another out, we have these neat little anti-trust laws in the us.

    independent research is the only research that is worth a darn.

    lastly, no one has yet posted any type of rebuttal to the simplest fact i keep bringing up. if this stuff worked, why don't the major oil producers put it in their product? it's a cutthroat world out there. why wouldn't they take advantage of something that worked?

    anyway... i wouldn't put it in my car. but you should feel free to do so. good luck.

    Why do FRAM filters contain PTFE? are they not supposed to be "DANGEROUS" to the engine?
  • ccotenjccotenj Member Posts: 610
    in the interest of both sides (see, i can be fair...)

    i wouldn't use it. note that they make no claims as to the effectiveness of ptfe. just "for those who like to use teflon based additives".

  • johnyoojohnyoo Member Posts: 18
    ccotenj,
    "Why don't major oil producers put it in their product?"
    That's not really a great rebuttal. (Please don't take this offensively) Logically, you're saying that you know all the reasons that they don't. There could be a multitude of reasons such as it costs too much to put it in and if they raised the price of their oil people might not buy it for fear that it's gimmicky could be one reason. There can be just as many reasons for why they don't place additives as there are reasons for why they could.

    But, I do agree with you in that I think I would like to see some more evidence before I jump on the additive bandwagon.
  • ccotenjccotenj Member Posts: 610
    nope.

    logically, i'm saying the marketplace moves on "new" "improved" "better" and so on. the way to nirvana when you are marketing a product that is essentially the same as the next guys (and let's face it, all the major brands are essentially the same, with minor differences in addpacks that 99.9% of consumers couldn't tell you) is product differentiation (and brand loyalty, but that's a sociological issue).

    as far as price pressures, it could be marketed as a separate type. there's enough of us out here who pay 4 bucks a quart for mobil 1. if independent research was shown that product x that had additive y in it was better, it would sell.

    btw, i'm not offended. :) if everyone agreed with one another, it'd be a boring cyberworld. i can take as good as i give!

    For now, I will continue using 100% "crude" in my engine. Assuming we are all here a few years from now, I will report on the progress of my engine in terms of repairs. While I maintain my belief about using real oil, I will certainly have egg on my face if my engine wears out at 100K with two years left on the lease, and the mechanic says to me, "remember all those folks on the 'net who recommended synthetic? why didn't you listen to them back in 2000?"
  • butch11butch11 Member Posts: 153
    Snake oil salesmen have been around since the very beginning of the auto age. Most auto user manuals say not to use them because they will not provide any benefit and some manuals state they may harm the engine or negate the warranty. Remember a post from an "engineer" from one of the SO firms-he said after adding their product-due to the reduction in friction,the engine would not generate enough heat to keep the car warm in the winter. SO proves PT Barnum's adage, "there is a sucker born every minute." I sell medical systems-we have SO salesmen in this market also-I love to talk to them-talking to idiots really provides a ego boost.

    Synthetic oil makes sense if you live in a extremely cold climate-like northern MN or Canada. Also if you really push an engine to the redline, then synthetic makes sense. If not, use a good quality dino oil and quality filter-see the filter study. Have 92K on my current accord-my old one has over 250K and is not burning oil.

  • bottgersbottgers Member Posts: 2,030
    If you plan on keeping a car for only a year or two, dino is fine. If you plan to keep the car for years and plan on putting several hundred thousands of miles on it, then synthetic is a must. You can pay a little more for synthetic now and avoid paying a lot more later, either by rebuilding your engine, or replacing your car.
  • 0patience0patience Member Posts: 1,712
    There is some benefit to synthetics,small,but some.It is not worth the extra money though.How many engines have you torn down?How many have you torn down that ran synthetic and how many with a good service schedule with regular oil?I can tell you,that there is little difference between the two.A good maintenance program,regular oil and filter changes and save the money.
  • marsha7marsha7 Member Posts: 3,703
    You do not know how refreshing your comments are to me. I was beginning to think that nobody used crude oil except me. Having observed a large number of cylinder head sludge, due to the lack of ANY oil changes, and the condition of my own with regular 3-4000 miles changes, I believe that regular changes are the answer, and crude is the product to use. My 175,000 Acura Legend (best car I ever owned) had to be sold because of all the add-on pollution crap that needed replacement and was very expensive, but the engine itself ran like a charm.
