Another Oil question

Post by Alspos »

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?

Synthetic motor oil in your gearbox??

I still dont know the difference between EPX and VMX trans oil.

But i do highly recommend Nulon G70 additive.

cheers

Man, do you think I can find 75/80 anywhere????? Faaar Out
They all have 80/90, but not thinner stuff. Bloody hell.
8 parts 80/90 gearbag oil + 1 part 20/50 engine oil = 660/9 / 770/9 = 73.33/85.55

Sounds like a good formula to me.......

Bloody Starions.......

I have also used 80w/90. Just have to wait for the gearbox to warm up a bit and it's fine. If you can only find 80w/90 then go with that.

Of course if you happen to stumble across some 75w/80 then grab it.
