I have used a lot of different greses over the years on my
buses. Prolly had the best luck with the red Amsoil synthetic, but I
haven't found a souce for it up here in Iowa and have back slid into
using the grease in the Meiserstatz kits. I grew up raised on MoS2
and had a gallon bottle of moly additive for the engine oil that you
put like a teaspoon in each oil change for the air cooled Vdub motors.
YMMV
