Anyone knows if one can use 80W-90 or 75W-90 synthetic transmission oil in the differential ? I cant find any diff oil around atm, and am doing a tune-up tomorrow so I need to know. Also, I'd need to know how much of it goes in the diff.

Thanks!

 

Ahh.. one more thing - I will also be changing the oil and found Castrol GTX3, 15W-40. Is that ok ?

 

yes you can run synthetic... i run mobil one synthetic in my trans and diff. either viscosity is fine.

yes on the gtx

 

My question is: can I run the same oil for diff and tranny ? Also, is 80W-90 ok, or is it too thick ?

Thanks!

 

I'm using Castrol Synthetic 75w-90 out back and Castrol GTX 20w-50 up front - Bosch filter.

 

i have mobil 1 75w90 in my transmission and differential

80w90 should be ok

 

i use royal purple 75w 90 for both tranny and diff.

 

yes you can run the same oil in both

Thx

 

Yup, same oil for both is fine. The diff on the FD does not need any friction enhancers, etc. -- regular gear oil is what you want.

Nobody answered the capacity part. So I will tell it here (from experience): The capacity of differential on FD is about over 1.5L and below 2L. So that you know how many bottles to buy

I have put in Mobil 1, 75W-90, full synthetic transmission oil. Priced about $15 / liter.

Also changed brake fluid to ATE Super Blue and changed engine oil, filter and spark plugs. About spark plugs in a new thread...

 

$15/ liter?!?! is that US $?

Tranyy takes 2.6 quarts or 2.46 liters
Differential takes 1.4 quarts or 1.32 liters


Buy 4 liters and you will be fine!

 

Yes, US $. Expensive I think.
