A recent article in the LA Times , brings up, again, the wastefullness of most consumers when it comes to oil changes. AMSOIL dealers can take advantage of this campaign by providing oil that is proven to extend well past 3,000-miles. AMSOIL offers 3-tiers of motor oil that go way beyond the 3,000-mile mark. Most vehicle manufacturers today do not recommend changing your oil every 3,000-miles. Engines and oils have been improved to last much longer. AMSOIL Signature Series is guaranteed for up to 25,000-miles or 1-year in most applications AMSOIL XL Series is designed to be used up to 10,000-miles or 6-months in most applications AMSOIL OE Series is designed to be used with the vehicles oil-life monitor system or longest OEM recommendation (typically 5,000 - 7,500).
