Hi guys

What is the correct fluid for front diff ?
Car has very low use.
Thx

I've used Mobil Delvac 75W90 in the past. Same as the gear lube in the tranny. Does not use much up there. Under a litre. IIRC.

Don't over fill, or it'll come out of breather vent on top, making you think something is leaking. Learn from others mistakes ��

FWIW (checking my records because I just did this in February) RMG in Sunnyvale used Redline 75-90w gear lube.

When in doubt go with the factory recommendation.

I used Delvac in the front diff, and the Porsche branded oil in the transmission - rumoured to be Shell PTX. I used the branded oil because it has better cold shifting characteristics, or at least that is the feedback from the people I have changed the oil for.

Cheers,
