I earned an advanced degree in DIY Automotive, Motorcycle, and Small Engine Maintenance & Repair from “Help My Dad University”. I learned from my father that maintaining vehicles and equipment regularly keeps them operating at their peak and prolongs their usable life. Over several decades I’ve had the opportunity to work on passenger cars, light trucks, motorcycles, and various small engines. My experience reinforces what my dad taught me: Use good oil in your engines and they’ll last a long time. I believe Amsoil is the best oil available.
