Application & Selection

How can I find the correct AMSOIL product for my vehicle or equipment?

Use the online AMSOIL Product Guide (enter year/make/model) and consult product data sheets for specifications.

Why are not all AMSOIL oils API-licensed?

AMSOIL prioritizes formulation flexibility to pursue performance improvements; some products are not licensed to avoid locking a formula. Where licensing is required, AMSOIL offers licensed products; always match the required spec for your application.
