Gearbox and rear diff oil.
 

I'm sure this has been covered many of times but I'm struggling to find a definite answer. Apologies in advance

Planning on changing the transmission oil this weekend and was wondering if I actually need the LS grade oil for my rear diff.
I was going to get the millers crx 75w90 nt for the front diff/gearbox and the millers crx ls 75w90 nt for the rear diff.
Now I'm thinking motul 300 for gear box and 90pa for rear diff.
Any recommendations for a good trouble free oil.
Will be going in a 2003 STi Blobeye.

Many thanks.

John.

I changed my box and diff oil in my 03 sti a couple of months ago and used motul 300 and 90 pa, nice gear change and running great:)

Did you use synthetic or ester for the gearbox oil?

That millers is top, it's what I've bought inc LS for diff but you only need LS if you have dccd otherwise normal crx 75/90 nt is fine

Gulf competition is pretty good ....

Pretty sure its sythetic ester based and the 90 pa is for ls diff so as said above not needed unless you got dccd

So will 6 litres of the crx 75w90 nth be OK and will that be enough to do both front and rear diff.

Thanks.

Hi

If you don't have DCCD, then 5L of CRX 75w-90 NT will do the gearbox and diff.

Gulf Competition and Motul Gear 300 are other good options.

I was just going to send you a pm regarding oil Tim.
Would you say the millers is the top one to go for... I'm currently using millers in the engine.

Thanks.

John.

Hi John

Toss a coin, those three are all top oils. Some reckon the Millers is brilliant in their car, others say the Gear 300 improved the shifts and some like the Gulf.

Okay that's brilliant Tim, I will try and see what oil works best.
Thanks for the info. Just ordered some millers from you.
