Diff oil or diff grease guys ??

[easy]

Just want to be sure I fill the diffs of the new RR with proper fluids.

What manufacturer makes the 100 000 or 300 000 diff fluids ?

Cheers

Use FG diff grease ( 100.000 WT ) in all 3 diffs. in front u fill it up to 100%, center 1 u fill up 75% and the rear diff 50%.

I just use a high quality synthetic grease. You can't put silicone in the diff it WILL leak out. If you are wanting better diff's look at the MCD LSD's.

It is possible to use a heavy weight silicon oil but it will start to leak - only slowly though.

I have been using 500,000 weight oil made by a company called Ultimate and distributed by Schumacher Racing. It was recommended by the MCD importer here in the UK as an alternative to using limited-slip diffs.

I no longer use a front limited-slip diff in any of my MCDs - I prefer to use the standard diffs filled with a heavy weight silicon oil. There is still plenty of front end traction and of course it the best bit is the cash saved in not having to buy limited-slip diffs for all of my cars!!!!!

The only thing to note is that the MCD limted-slip diff is stronger than the pre 2008 spec standard diffs.

Hi there

thank you guys for the ideas.

I tried the high heat and pressure grease and it is very very stiff.

Works perfectly.

Lucas makes some good greases too.
