    Will AMSOIL Motor Oils void the warranty
    of a new vehicle?

    Absolutely not! Manufacturers’ warranties are based
    upon the use of oils meeting specific API Service Classifications, for example, SJ/CF.
    (AMSOIL lubricants meet the current API Service requirements and, thus, are perfectly
    suited for use in any new vehicle without affecting the validity of the new vehicle

    What is the
    “AMSOIL Product Warranty”?

    Simply stated:

    AMSOIL, Inc. warrants that the
    use of its lubricants will not cause mechanical damage to any
    mechanically sound equipment when AMSOIL Inc. products are use
    in full compliance with the company’s recommendations and

    What is the Four Ball Wear Test? How good a
    predictor of engine wear is it?

    The Four Ball Wear Test puts one rotating ball against
    three fixed balls under specific conditions of pressure,
    temperature, revolutions per minute and duration. The test may
    be used to evaluate the friction- and wear-control ability of
    liquid lubricants or greases in sliding contact. The Four Ball
    Wear Test is a good laboratory tool for developing oils with
    good engine wear control.

    The results appearing on the
    AMSOIL Series 2000 20W-50 Racing Oil (TRO), Series 2000 0W-30 Motor Oil
    (TSO), and Series 3000 5W-30 Heavy Duty Diesel Oil (HDD) bottles were from
    testing done by a well known independent lab. Such a facility
    would not jeopardize its reputation by misrepresenting test
    results just because AMSOIL was paying for the tests to be

    AMSOIL ran literally thousands of
    tests in our own lab before we sent the product for testing.
    The independent lab’s results correlate very well with our

    Should I use oil
    additives with AMSOIL?

    No. AMSOIL is a solo act.
    Everything your engine needs for lubrication and protection is
    in the oil. Additives can upset the oil’s precise chemistry,
    or worse, interact with the oil in unpreductable and harmful
    ways. Save your money … and your engine. Skip the

    Will my oil
    pressure or idle rpm change when I switch to AMSOIL?

    They might. AMSOIL is a better
    friction reducer than conventional oils and friction directly
    affects oil pressure and idle speed. Less friction in the
    engine will lead to lower oil pressure and more rpms at idle.
    Since synthetic oil doesn’t have to “push” as hard to overcome
    friction as conventional oil does, the oil pressure drops. The
    engine still has adequate oil circulation, but like the heart
    of a person whose blood pressure is lowered through
    medication, the engine doesn’t have to work as hard for the
    end result.

    What is the NOACK Volatility Test?

    Volatility, measured by the principal European test
    called NOACK, is the amount of oil lost (the light molecules)
    over time at a given temperature and pressure. It has a direct
    impact on high temperature engine oil effectiveness —
    especially on viscosity, emissions and oil consumption.
    Today’s oils have a NOACK volatility limit of 22 percent.
    Volatility losses for the coming ILSAC GF-3 oils — due on
    store shelves just after the turn of the century — could
    quite possibly be limited to 15 percent for all grades.

    When an oil suffers from high
    volatility, and the lighter molecules evaporate, the oil
    thickens gradually getting out of “spec” and adversely
    effecting the performance of the lubricant and placing the
    engine at risk.

    I have driven
    diesels for as long as I’ve been driving. I am still hesitant
    in using AMSOIL mainly because I don’t understand how an oil
    can CLEAN (or keep clean) a diesel engine if you don’t change
    it regularly. Also, the main oil companies claim that
    synthetic oil left in too long will cause “deposits” in the
    upper cylinder or “rings” area.

    The answer here is a lengthy one, so settle in.
    Actually, your question is
    the one most often asked, in one form or another, about all both diesel
    and gasoline engines. It is
    the one that we, as AMSOIL dealers, must answer
    as the public in general has been so engrained with the
    concept that changing oil often is good and necessary, and
    changing even more often is better. Think about it. . . If
    everyone were to simply double their oil change interval from
    3,000 miles to just 6,000 miles, the amount of oil sold would
    be cut in half. Lubricating oil, in essence, is a by-product
    of producing gasoline. From a barrel of crude oil, gasoline
    (and other fuels) is refined as the main product (there being
    no substitute, at least not yet) Dispatching Services and everything else from
    lubricating oils down to the thickest of asphalts is a
    byproduct that must be gotten rid of. Therefore, the oil
    companies preach and advertise changing oil more and

    The fact is that when you look at
    synthetic oils, they do not deteriorate like fossil-based
    oils do. Their molecular structure, being formulated to be
    tighter and to have specific properties lasts longer and does the job
    better (unlike petroleum oil
    refining which simply separates out the base constituents into
    the different product categories). Although AMSOIL came out with
    the first API approved 100% synthetic oil back in 1972, every
    major oil company is now pushing a synthetic oil, probably seeing the
    writing on the wall!!! They don’t necessarily push it hard, as
    they still have a main business to support, but they must be
    part of the pack to get the experience and marketing position
    for the future. You may be aware of the API SJ (ILSAC
    GF-2) category of oils that just came out late this past
    summer. The next generation of oils, GF-3, is expected to have
    such a level of performance requirements that the oil will
    have to be at the very least a blend of petroleum and synthetics to
    meet these requirements. This gives you a picture of why the
    oil companies are posturing as they are.

    As for extended drains, even our diesel
    oil is only recommended initially as a 15,000 mile/1 year oil
    drain for most diesels. Some diesels, however, such as the
    Volvo VE D12, have a recommended change interval by the
    manufacturer of 25,000 miles. Mack, Cummins and others are
    likewise designing engines for extended drains as the truck fleets demand
    it! Our oil meets these manufacturer’s requirements and
    can be used for these extended drains as the manufacturers
    build in better filtration.

    Filtration is of the utmost
    importance to achieve more of a drain interval, coupled with
    oil analysis. Oil analysis determines the condition of the
    oil, and if you can determine that the oil, whether it is
    after 15,000 miles, 50,000 miles, or 100,000 miles, still
    meets the manufacturer’s specifications for oil to be used in
    a particular engine, why change it???

    Most oil filters filter only to
    25 microns (one micron=.000039″). The finest tolerances in a
    typical engine is in the 5 micron range. AMSOIL’s by-pass filters filter 98%
    efficient – one pass – at 3 microns. They will filter down to
    less than one micron, but at a much less efficiency rating. As
    a result, you are capturing dirt that will not only cause
    wear, but also keeping dirt out of the oil stream where it
    works to deteriorate the oil’s additives. Changing the by-pass
    filters once per year (or every-other full flow filter change)
    typically keeps them working in top condition (but even if
    they get fully stuffed up, you aren’t hurting the engine as
    you would still have the full flow filters). In addition, the
    AMSOIL by-pass filters hold
    water, which is a by-product of the combustion process. Water,
    mixed with other combustion by-products form acids and help
    deteriorate oils and additives.

    As you stated, the oil cleans the
    engine, but the oil also acts as a conveyor of the dirt and
    other contaminants (metals, water, etc.) to the filter. If the
    filter can not remove the contaminants, or does not have the
    capacity (gets stuffed up and the by-pass valve clicks open
    and dirt is continuously circulated) then you have problems.
    But if the dirt is conveyed and held out of harms way, then
    the oil can do its principal job (lubrication) longer and the
    engine will last longer (less dirt in tolerances, smoother
    operation and better performance).

    But oil analysis is the key
    to extending drains past the base 15,000 miles/one year
    period. With oil analysis, I’ve seen people go over 200,000
    miles without an oil change. You change full flow filters and
    by-pass filters, and the make-up oil sweetens the additives
    and helps keep the oil in spec. The oil remains within the
    manufacturers specification, proved by the analysis, and no
    warranties are effected. The oil analysis is actually better
    than a stack of receipts from cases and cases of oil!

    As for the deposits, this is a
    typical oil company reference to synthetic oils where other
    oil manufacturers utilize the same additive packages as in
    their regular petroleum oil which is formulated for shorter
    oil change intervals. Once the additives have deteriorated
    and/or the oil filters have clogged, the circulation of dirt
    and acids cause the build-up around the rings, ring seal is
    compromised, and oil getting by the rings carbons up the upper
    cylinder area.

    It is a fairly complicated
    process, and much of it just requires you to think about how
    the world is and who is telling you what. Most mechanics who
    preach 3000-mile/3 month oil changes were preached to by the
    oil supplier and the same television ads you read with the
    “pay me now or pay me later” lines. The only real way you will
    be convinced that you have been fleeced is the same way I
    convinced myself that big oil has been leading us down the
    prim-rose path, and that is by just trying AMSOIL. AMSOIL
    sells oil analysis kits and when you see how easy the engine
    starts in cold weather, and how the amount of wear is reduced
    (do an analysis on the oil you have in there now at 3,000
    miles, then try AMSOIL and do one at 3,000 miles, or more, and
    see the difference) you will be convinced of the
