Oil Change Intervals

According to Lubes 'n' Greases Automotive Editor David McFall (February 2003), the average gasoline engine oil change interval in Europe approached 10,000 miles. He credited a tiered motor oil rating system that distinguishes the higher quality oils from the lower quality oils, which allows European vehicle manufacturers to encourage longer oil drain intervals, if a higher quality oil is used.

No standards currently exist in the U.S. that distinguishes premium synthetic oils, such as AMSOIL, from conventional motor oils. There is no motor oil rating system that will actually rate oils as to their quality level and drain interval capabilities. Unfortunately, in the U.S., motor oils are only required to pass a minimum quality standard, which leaves consumers uncertain about how often to change oil.

U.S. consumers deserve the same motor oil rating system that Europeans have! Until that happens, you can rest assured knowing that for over 35 years AMSOIL has been manufacturing premium long-life synthetic motor oils and countless motorists have successfully used AMSOIL at the oil drain interval recommendations (271 kb pdf) of AMSOIL, Inc. — AMSOIL is a proven top-tier motor oil!

Best Oil Change in America Labeled "a Flat-Out Bargain!"

In a subsequent article (March 2003), David McFall writes: "Amsoil, which claims to be the world's largest independent marketer of synthetic engine oil, stakes its reputation on longer drain intervals … and backs it up with a full replacement engine warranty. Moreover, it has done so for three decades without a single proven case of oil-related failure in an engine covered by its warranty." McFall added, "Purists can sniff that Amsoil's data isn't derived from a controlled field study, but the sheer mountain of vehicle miles over three decades, and the absence of any confirmed performance, wear or maintenance issues, speaks volumes." McFall labeled AMSOIL, "a flat-out bargain" and credited AMSOIL for providing an environmental bonus.
