Fluids

[john]

What have you guys used in the front & rear diffs, as well as the 5mt? It's about that time.

5mt - I made a big mistake the first time I change the fluid and used a heavier weight. It felt like the car lost 50 hp.

Now running the standard Valvoline with the recommended weight.

So 75w-90. I'm going to look for a synthetic for the tranny & rear diff, I believe. And some Castrol GC 0w-30 for my motor.

Careful running syn in the tranny, as I've read that our trannys require a certain additive to keep the gears from slipping out. Some of the .com'ers have had this problem.

If you do, make sure the syn has the right additives that your tranny requires.
