Gearbox & Diff Oil Change - Opinions?

[dave_t]

Got a couple of days off towards the end of the week so i plan to do some general maintenance on the S15, starting with a gearbox & diff oil change.

edit:- i should add i do plan on taking it to the nurburgring, and attend a couple of track days in the not so distant future, so that's one of the reasons i want to put 'some of the good stuff" in there.


Now since iv'e been involved in SR's, iv'e always been recommended to use Redline shock proof for the gearbox (never inquired about the diff)

What is regarded as the best to use, what are you guys using?

It's certainly not the best because it's not the dearest but I've always used /fuchs boa 90 and the diff has been great...

For anyone thats interested, here is what Tim @ Opie Oils suggested:

"Hi David

Your car would require a 75w-90 for the gearbox and diff and here are the ones we have.

http://www.opieoils.co.uk/c-673-75w-90.aspx

If you want to go for the best, the Millers CRX 75w-90 NT, Gulf Competition, Motul Gear 300, Redline MT90/Lightweight Shockproof and Millers TRX are ideal for the gearbox. The Castrol Universal, Motul Motylgear and Fuchs Gear Syn are all decent alternatives. The Fuchs Syn 5, Motul Gear 300LS, Millers CRX NT LS, Gulf Competition LS and Redline GL5 are ideal for the diff.

Regards

Tim"

how did you get on with the above dude ?

im thinking of going for the millers 75w90 for the gbox and the ls for the diff (have a 2 way) .

I run redline lightweight shockproof in mine. Runs much smoother with it in. Also as Lupix said Fuchs syn 5 in the diff
