My 2008 Carrera S is reaching 30k miles and I like to change its manual gearbox oil. I did some research and it appears that 3 quarts of Mobil Delvac Synthetic Gear Oil 75W-90 should do the job. I wonder if this is correct?

 

just buy a gallon, believe it takers just over 3 qts. I changed mine recently, not too hard, just takes a little time. Take the fill plug out first in case the bottom plug doesent..
I used swepco, no difference from stock fill IMHO

 

Which Swepco did you use?

Thx

 

Swepco 201,,pelican parts has it,,never seen gear oil blue,,it did take some of the notchiness out of going into 2nd.

 

Cool! Thx.
