Product Selection FAQs
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.
