Synthetic motor oil

    I'm waiting for the results of tests being done on a veggie based engine oil. There is a company on Colorado blending a non-toxic biodegradable oil from canola and other veggie oils. It is being tested in fleets including the US Postal Service.

    There is validity in whats being stated, I've been using Amsoil a few years before Armtdm has really wieghed researched heavily before deciding it's use, have found it to live up to it's statements has done well for me still is, I'm not saying anyone has to go out an use this product, synlube just apprising those here of it's existence.

    Quite noteworthy is fact that everyone has somewhat rushed and taken that quantum leap and embraced the coolant now marketed, everyone including automotive manuf, this developement was just a few years in the making and now has become the staple of which maintains the cars cooling feature, and yet we were preached every 30k or 2yrs max 3yrs change, because coolant transitions into a corrosive, when left to long didn't see much uproar over this technology seems accepted now wander what gives?

    Wander also whats the measuring line and or the touchstone we use to gauge whether one oil is better than another given we are not lubricating engineers or chemist, what sources do we rely on and do we have enough knowledge of all the products and competition to advocate one over the other as being better or best

    Does the fact that it is a mom and pop shop negate or nullify the products inferiority or superiority to that of a much larger enterprise that produces lubricants, is bigger better don't think so, time has a way of enlightening us, this company synlube has had a rather low profile over the years comparitive to its competition does that make it's product in and of itself unworthy, perhaps not, does it deserve some attn perhaps

    Given the depth of information and explanation into tribology and mechanic of an internal combustion and the major role oil plays, all things appear somewhat logical and reasonable, trying to educate someone prior to selling them their product I think is truly a good thing if anything the individual has a more informed understanding of automotive engineering and lubrications special role.

    I asked about comparisons to other oils and independent lab resutls!

    Well, their response follows exactly as sent to me. Rather arrogant too!

    Thank you for your interest in SynLube

    There are no tests that can compare our products to conventional
    Petroleum or Synthetic API Licensed oil that is designed to be used for
    3,000 to 7,500 miles, when our product's minimum service life is 50,000

    And 100,000 to 150,000 miles is NORMAL service life, with many vehicles
    have been driven up to 20 years or 300,000 miles without ANY OIL CHANGES

    You can contact any and all of our long time customers through our web
    listed in "Syn Uses".

    Our control tests are done for us by CTC, Southern California Auto Club,
    Automotove Institute in Prague, and SouthWest Research and San Diego

    Information not presented on our web is proprietary and therefore not

    In 26 years that we have offered our "Money Back" warranty, i.e. IF YOU
    INSTALL SynLube in YOUR vehicle and are not satisfied with its
    performance for ANY reason, just drain and send it back for a FULL
    REFUND, no limitations, no time limit, no mileage limit, and in over 26
    years and over 17,500 US customers and 34,000 European installations not
    one customer ever wanted a refund.

    Just try that with: Mobil 1, AMSOIL, Red Line or Royal Purple, Castrol,
    Pennzoil or Quaker State!

    Our oil makes that much NOTICEABLE difference, no amount of simple few
    minute bech tests can or does simulate what happens to real motor oil in
    real life operating conditions over 10 year interval, which is typical
    for our lubricant.

    You have to realize that our formulation which has been UNCHANGED since
    1985 still exceeds all specifications of ILSAC, API, ASTM and ACEA for
    2002 vehicles, some of these "regulatory" institutions did not even
    exsist in 1985 !!! And the basic formula remains esentially same since
    1969, It took 22 years of research to develop (1944 to 1966) most oil
    companies have not even had their synthetic oil available for that long!

    Typical motor oil specifications are for the MINIMAL performance that has
    to be met by FRESH OIL, there are no specifications for WEAR, fuel
    economy past 3,000 miles nor any long term catalyst or engine durability.

    The "bech" test engines used to API specifications are all obsolete, and
    only one of the "test" engines is still in production. The API SL
    specification for NEW 2000 model year vehicles is 30 months BEHIND
    schedule !!!

    I believe that spending $165,000 to test motor oil on engines that are
    not even in current production is total waste of time, money and
    resources, that is why our company test our products continuously in real
    life driving in real production vehicles.

    See our web "Test Cars".

    Dex-cool was developed by GM to cover up a problem with corrosion of their intake manifold gaskets with their V6 engines.. Ethylene glycol it seems was the culprit. I embrace it in my corsica because I don't want another $450 failure. My Toyota and Sentra will continue to get the ethylene glycol treatment.

    gsleve: Do you use Synlube??
  • dpwestlakedpwestlake Posts: 207
    Somehow getting back the price of the oil in the event your engine is destroyed doesn't sound like a great deal. especially if the manufacturer blames the oil and voids the warranty.
  • gslevegsleve Posts: 183
    No I have'nt, still researching it, the dexcool was developed in conjucction with texaco and synlube dexcool is a diluted version of synlubes version
  • adc100adc100 Posts: 1,521
    It was done under GM licence. Dex-Cool is a registered trademark of GM. As I said, due to their screw-up.

    I've read just about the entire sit and in all honesty it looks and sounds to good to be true to me. I found that there test vehicles were mostly 30yrs old ,they have about 15 cars on the road from the 80s to a 2001 suzuki esteem but the highest miliage is about 130k you can get 150k out of the bargen brands with the 3000 changes easy. My wife just purchased a 2001 tracker/suzuki and I emailed synlube for a price to convert. 150.00for the kit. I figured if I used the chevron synthetic 5Qt+purone filter 3.69Qt+4.99filter=23.45 I go 5000 changes she will drive close to 10k a year.I can do 6 oil changes for a total of three years at 140.70 bucks so using synlube for me would take 3yrs to break even.The only advantage I see is less oil in the enviroment.This is only a couple of issues. Theirs the less friction/wear/2-4%gas saving they say there oil promotes 3-10 times the life span of the engine. Chevron delo400 75-90 gear oil has a million mile warranty if you use it for the first fill and follow the manufactures change interval in your 18 wheeler and it petrolium based. I thought mobil had a car with a million miles on it with little engine wear? This synlube may be a great product but I'm not seeing the 30buck a quart benefit.
  • armtdmarmtdm Posts: 2,057
    What surprised me was the ATF change interval of 30,000. My new Buick has a factory fill severe service change of 50,000, 100,000 normal servce. Plus, Amsoil ATF says 2-3 times the recommended change interval. So, no great worthiness here!

    Their claim that the Teflon particles are so small and in a unique suspension sort of bothers me given that Teflon has never been proven to provide any benefit that I know of!

    "mixture of coolant and synthetic water", see:

    Well, once upon a time Microsoft advertised "32-bit mouse" for 32-bit Windows-95. Not better nor worse... but still border a fraud.

    My 2001 Honda Civic recommends ONLY 5W20 oil. To my knowledge, Amsoil is the only manufacturer making that weight oil in a synthetic. Like many others, I am not convinced that this light oil will provide long-term protection of the engine and want to at least use synthetic in this weight. Honda claims that synthetic is fine and 5W30 is ok if 5W20 is unavailable but should be switched back to 5W20 as soon as possible. Will 5W30 synthetic provide better protection and comparable viscosity to conventional 5W20 or am I better advised to stick with 5W20 in a synthetic? I'm hoping that the automaker's push to eke another mpg or two out of their cars by switching to lighter oil doesn't compromise their long-term reliability (Ford is recommending this oil in certain new models also)...
  • treyh1treyh1 Posts: 34
    An easy way to check is to find a 2000 Civic and see what Honda recommended. If it was 5w30 in 2000 models, and I suspect it was, then I'd go with 5w30, synthetic or not. This is a mileage game for their CAFE, not a benefit to the consumer.
  • rcarbonircarboni Posts: 290
    I don't think lighter necessarily means less protection. Synthetics typically have better additives and boundary lubricants. These are more important in reducing wear than the oil weight.

    I think Royal Purple has a 5W-20 product.
  • There are a few shops in the area that now provide Agip Oil. I asked one shop about it and wanted to see spec sheet. They were unable to find information but said if they found it they would save it or send copy to me. It's supposed to be 100% synthetic, made in Italy, and standard oil in Lambroghinis. They offered an oil change with this for 19.95. Bulk was all they use. Also offered choice of Castol or Valvoline for 14.95. They said the Agip was supposed to be much better than Mobil 1. I would appreciate any further info on Agip Oil. Thanks.
  • vadpvadp Posts: 1,025
    <<<They said the Agip was supposed to be much better than Mobil 1.>>>

    and couldn't provide any info to back up the statement.image

    Also check out their product line. Not impressive to say the least.

    You might want to take a look at the following link:

    There are some interesting specifications and data for different oils on that page.

  • bluedevilsbluedevils Posts: 2,554
    The Target store nearest my house (Detroit area) just dropped its price on Mobil1 from $3.89 a quart to $2.94. That is 60-70 cents a quart cheaper than I've ever seen Mobil1. I've checked one other Target near me, and it has NOT dropped its Mobil1 price like that.

    Just thought I'd mention it. Mobil1 users may want to check out their local Target store the next time they need to buy Mobil1.
  • adc100adc100 Posts: 1,521
    Are you sure it's not the new Mobil 1 blend.
    Like the "cyclops" How'd you do that??
  • Agip not that impressive. Motor Oil Primer was a great site. Havoline is one of the best Dinos and is what I use most of the time. Thanks again for the info.
  • armtdmarmtdm Posts: 2,057
    Not impressive at all. Poor descriptions, etc. etc. etc.
  • adc100adc100 Posts: 1,521
  • bluedevilsbluedevils Posts: 2,554
    No, it's not the Mobil Drive Clean Blend (their relatively new synthetic blend, right?). I've seen that stuff around town, but this stuff at Target is the silver bottle, "Mobil1" "Tri-Synthetic"-- green cap for 10W30, blue for 5W30, etc. It was $3.89 a quart at my Target, which was a decent price. I have no idea why they dropped it to $2.94.
  • adc100adc100 Posts: 1,521
    Need to get me some. I didn't think the "Drive Clean" stuff was their blend. I thought it was to cheap for that. Isn't that the stuffin the solid blue can?? Yhanks again for the info. What are you doing up at 04:30???

    Hey Mr Shiftright. Did you get that information I sent????
  • palfito01palfito01 Posts: 10
    Are Mobil and Amsoil synthetics virtually the same? Which one is better.

    I need 5W-20 and from what I have heard Amsoil is the only synthetic so far. Amsoil is telling you to change at 7,500 miles or 6 months, whichever is sooner. The 5W-20 weight Amsoil is different then the other Amsoil weight synthetics. Why do they recommend 7,500 miles and not 25,000 miles? What is the difference between the Amsoil 5W-20 and the Amsoil 5W-30. They have different change recommendations.

    Is Mobil coming out with a 5W-20 synthetic any time soon? Thanks.
  • armtdmarmtdm Posts: 2,057
    The Amsoil 5 W 20 is the XL label which was designed for the quick lube business where people are reluctant to go beyond 7,500 mile changes.(or 3000 for that matter) To capture that market they formulated the XL series of oil. The additive package is not as good ( meaning not as durable for extended use) as the other oils that are slated for 25,000.

    It's actually that simple!
  • rcarbonircarboni Posts: 290
    (I think we need to consolidate topics)

    Basically, the Amsoil XL oils are API approved, which is a bunch of marketing hype. Because of the lower levels of phosphorous and such, they don't recommend them as extended drain oils. They simply offer them to people who want a warm and fuzzy by staying within manufacturers recommendations. Here is a better explanation:

  • taasstaass Posts: 40
    This is not a synthetic blend. As adc100 noted, it is too cheap for that. It contains an additive package with slightly more robust detergents. I can't give details because I don't know the details, but that is what Mobil claims. I've used it before in other vehicles with no problems.
  • dhughes3dhughes3 Posts: 56
    Sorry, but I've always had great longevity from Chrysler engines, going over 200K in a couple of instances.
    Update on the synthetic oil vs lifter noise: I put in a quart of Rislone at my last oil change, and the duration and severity of the noise is decreasing with every start. I think the Mobil 1 truly must be the cause; just isn't keeping the lifters clean.
