Rear Differential gear oil?
what do some of yall recommend for Rear Diff gear oil?
im going to be draining the stuff thats in my diff more so to check it and make sure all is well and that there are no metal shavings in there! im just curious to know whats the best stuff to replace it with! so whats yalls recommendations? |
Full synthetic is usually best in my opinion.Mobil 1 and Royal Purple are both good.
|
i already did a lil search on it before people start bashing me!
people say Redline 75w90! what are some other choices? i would just like to hear it from the guys who really push their cars to the limit than some pussy footers that dont! |

Mobil 1.
Or, just any 75-90 gear oil. |
Redline LightWeight ShockProof Gear Oil
I used to run the heavyweight, but my engine guy who also used to crew chief for an MX5 cup team suggested the lightweight was enough and that I would have less parasitic loss. If you run a clutch type diff, all bets are off. |
The shock-proof is too much.
my preferential hierarchy for 75w90: motul redline amsoil M1 dogshit royal purple |
oh, and change the oil in the front diff too.

Redline

Should I use the same stuff in the transfer case, or is that just distilled water?

I've been running Royal Purple for over a year and haven't noticed anything (good or bad). So I guess that is good? |
