Just got my Diff rebuilt on my caterham. Standard De-Dion rear end with 3.62 ratio sierra Diff.

What oil is recommended?

Cheers Steve

The assembly guide says "Caterham diff oil EP90"

It is available from their site, but when I bought the first fill package, it was Comma oil they actually provided.

I've just changed to Castrol Syntrax Limited Slip 75w-140 oil which I hope will make the diff a bit quieter and is OK for open diffs.

Sorry to be vague but i spoke to Opie Oils and he recommended a very unusual oil, he said it would help reduce Diff noise, which i would have to say it marginally does!
Don't be put off by the oil as it is Bright green!!
Infact i had to ring him back when it came through as i thought they had got it wrong!
If you mention the 'Green Oil' i am sure they will know which one, definately quieter than before changing it.
