A real dealer. A direct conversation.

An AMSOIL customer long before I became a dealer.
I’m Trey Campo. Before becoming an independent AMSOIL dealer, I used AMSOIL products for more than 10 years in all my personal vehicles and equipment—and throughout the commercial lawn-care equipment in my grounds-maintenance business.
That experience gives me a practical understanding of maintaining equipment for everyday life and work. Tell me what you drive or maintain, and I’ll help you find the relevant AMSOIL product information and buying options.
Choose with evidence
Make your decision with information you can check. Review official AMSOIL performance tests and the exact product’s applications and instructions. Test results apply to the products and conditions described.
From product question to the right next step.
01 · Identify your application
Start with your year, make, model and engine. Check the requirement for the component you are servicing.
02 · Choose your buying path
Shop directly, compare PC membership for personal use, or select the business program that matches your needs.
03 · Order through AMSOIL
Review the exact product information and complete your order on AMSOIL. Keep the product and service details for next time.
Clear answers before you buy.
Do I need a membership to buy AMSOIL?
No. You can shop through the AMSOIL link without joining the Preferred Customer program. PC membership is an option for eligible personal-use buyers who want its current benefits.
What does Preferred Customer membership include?
Eligible Preferred Customers receive up to 25% off standard online retail prices on eligible products. The U.S. program offers a $10 six-month trial or $20 annual membership before taxes. Review the official terms for current benefits, exclusions and eligibility.
Which AMSOIL account fits my business?
A retail/installer account is for eligible businesses selling products or installing them for customers. A commercial account is for products used in your business’s own vehicles and equipment. AMSOIL determines program eligibility.
How do I find the right AMSOIL oil for my vehicle?
Start with the official AMSOIL application guides and your owner’s manual. Confirm your engine, viscosity and required specifications. If the listing is unclear or your equipment has been modified, ask before ordering.
Can Trey help customers outside Spokane?
