General Info

AMSOIL is the first 100% synthetic lubricant to be API and SAE approved. Others may try to copy AMSOIL's quality, but none can or will. AMSOIL always strives to stay ahead of changes in your vehicles lubrication needs, offering OE change intervals all the way to 25,000 mile or one year (whichever comes first). Better protection, better mileage, better value, that's AMSOIL since 1972
