I've no idea about gearbox oil but I've just searched using "Oil" and "GT4" and he reckons an oil change needs 8.5 litres which stacks up with my OPC charging for 9 when they did mine recently.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

I was also wondering which gearbox oil to use and what quantity my gearbox takes (2002 C4 facelift). I've read different quantities on the web up to 4 litres. About 8.5 litres for the engine oil.

I feel sure someone will come along with definitive info at some point today! I shall watch this space (I'm guessing it will be GT4, it's like fishing...patience, patience) :roll:
