How much gearbox oil?

[Dean_82]

In a rev3 turbo?
Also what oil is recommended? MT90 is not a option sadly as car is in having a clutch change now. I'm guessing they will have some at the garage its in. Its a Renault garage. The same oil they put in the Megane turbos an option?

You fill the gearbox with oil until it begins to run out the filler plug on the back of the box.

75w-90 synthetic gear oil is the stuff you want. The diff in a turbo box is sealed so you're not lubricating that, you're just lubing the gears. It's generally between 3.5l and 4l depending how much of the old stuff you drain out (ie how long you leave it dripping and how hot it was when you opened it!).

Yep 75w-90, loads are popular Redline, Motul, Silkolene etc http://www.opieoils.co.uk/c-673-75w-90.aspx
