 Amsoil synthetic lubricants. Folks, Amsoil works different than other synthetic and conventional oils. It actually runs to heat and friction and won't release and run back into the oil pan until the engine cools. Its ester additives also condition oil seals, keeping them pliable so it prevents and sometimes will actually stop oil leaks, prevents engine wear, and extends your drain intervals. Best part is it's available for all internal combustion engines.
