"Every time that I slide a feeler gauge between the rocker arms and valve tappets to check the intake/exhaust valve adjustments, I am amazed at the amount of AMSOIL that clings to the gauge - even after the engine has sat for 3 or 4 days without being run. It was a noticeable difference over the petroleum oil that would rapidly run back down to the crankcase. My findings have convinced me that there is no other oil good enough for my racing engine."
