Frequently asked questions
When should I switch to High-Mileage Motor Oil?
A good rule of thumb is at or around 75,000 miles — the widely accepted threshold to begin a more robust preventive-maintenance program for maximum engine life.
Is this right for my older Tundra, Tacoma or 4Runner?
It's an excellent fit for high-mileage Toyota and Lexus engines: targeted seal, deposit and wear protection. For ultimate performance and protection regardless of miles, Signature Series remains AMSOIL's top choice.
What's the drain interval?
Up to 12,000 miles or 1 year, whichever comes first, in normal service (see your owner's manual for severe-service schedules). Always change the filter when changing oil.
