What to use?
I would like to purchase it this morning..
How'd you go? I dont recall having to get any but that TB or VS guys have talked about it. LT would know .
Maybe volvo brand was the one to use .
I am going to use Penrite 75-90 fully synthetic gear oil.
Bought it today, ran out of time to get it in the box, will get it in there tomorrow.
The Penrite 75W-85 Fully Synthetic is pretty close to the original Volvo specs. Not too sure on the 75W-90. Shouldn't be much difference
