If there was a popcorn smilie on this board I would use it....very interesting... I can see where ya coming from there strokes.... syn is sometimes too slick for stuff like that to grip properly and still lubricate. say in a gearset. There is nothin' wrong about semi syn it defiently has its nitch... A couple people around here run bypass filters on full syn Amsoil in their diesel trucks getting 50-60k on an oil change. It is a proven fact that it doesnt break down as easy with pressure and or heat....but other than that its the same....
