Another Oil question
Posted: Wed May 12, 2004 6:29 pm
Another oil question cos I still can't quite figure out viscosity ratings.
Castrol website specifies VMX-M 75W/85 for the Starion gearbox
It also says you can use EPX 75W/80
In one of the lists of Starion things I have it lists EPX 80W/90 as gearbox oil. The 80W/90 of the Castrol site says use it in tractors,trucks and a few other things.
My question is, if you use the 80W/90 will it protect any better? Will it crunch until the box is warmed up more than 75W/80 will? Are there any other drawbacks, mine is just a street car?
