Kendall GT has been one of the "racing oil" favorites for years, and is one
of the preferred brand of the Porsche folks. It supposedly has a much higher
content of one additive (zinc, I believe) that is better for wear
characteristics. When you have oil-cooled engines, oil brands become more of
a heated topic!!

Ron,
Just for fun, I went through all my Amsoil lit, and don't
find Kendall oil anywhere. My guess is it isn't one of the
leading brands, but that is just a guess, maybe it is a
truly superior oil and Amsoil is afraid of it! :)
