Hi all, service time tonight. Bought 5 litres of oil for 05 STI gearbox and rear diff. Have i bought enough? Is it right that you put 4.2 litres in gearbox, 0.8 in rear diff.
Is it right to fill rear diff untill it comes out of the filler hole?

Bet you all thought i was going to ask what oil to use didn't you.

Cheers in advance.

 

Yes

 

What oil did you use? Same as earlier non widetrack sti's?

 

What oil does Sunaru recommend for a Sti with Suretrack rear diff?

90 PA or 75W-90?

I know for the gearbox/front diff it is 75W-90 but I have no idea for the rear.

Thanks!
