You are not going to wear out anything in your transmission because of the brand of lube...
All a 5 speed needs is any brand 85w90 gear lube and it will last just about forever.

Yep .. The dipsticks left something more to be desired ... While one gear oil may have more "magic" in it I've seen a gearbox failure because of a brand of gear oil being the culprit although Shock Proof did seem to quiet up my 6 speed when it was new ...

They all work.
I do prefer these two in the other two holes.
But I wouldn't get a tattoo of either of the brands.
(I have seen both Amsoil and Seafoam tattoos).
