Is AMSOIL worth the extra cost?
AMSOIL costs more up front, but it's built to go further between oil changes — often eliminating an oil change per year — so you buy it less often, which helps offset the price while adding protection. For a tuned, supercharged or towing build, the added wear and heat protection is exactly where a premium synthetic earns its keep.
