Which gearbox oil?
 

Which gearbox oil do I need for my car? It's a 2004 non turbo blobeye, 5 speed manual gearbox.
After doing a little research I believe I need 75w90 fully synthetic. Is this correct?
Thanks.

Hi

You need a 75w-90 for the gearbox and diff and here are the ones we have.

If you want to go for the best, the Millers CRX 75w-90 NT, Gulf Competition, Motul Gear 300, Red Line 75w-90NS and Millers TRX are ideal for the gearbox. The Castrol Universal/Universal Plus/, Motul Motylgear and Fuchs Gear Syn are all decent alternatives. The Fuchs Syn 5, Millers CRX, Redline 75w-90 GL5, Motul Gear 300 and Gulf Competition are ideal for the diff. The Fuchs Sintopoid, Castrol Syntrax Longlife, Millers TRX, Motul Motylgear, Mobil SHC and Gulf Syngear are also good choices.

Thanks for the info, helped a lot! How much would you recommend buying? 4 litres?

The gearbox takes 3.5L, 0.8L for the diff.

Cheers Tim I will be buying at the end of this month :)

I have literally just (2 hours ago) changed the oil on my 2001 wrx. I used the motul 300. I cannot recommend it enough. The gearbox is transformed!!

It's very good stuff

I've just finished changing the gearbox oil on my MY99 Subaru Impreza WRx. After checking the manual bought 4L of Motul MOTYLGEAR 75W90 (manual said it took 4L).
The thing is, the oil isn't even on the "L" of the dipstick.

I had previously changed the rear diff with Motul 300, so I still have about 200ml of it, I was thinking of adding 100ml to the gearbox. What do you guys think? They are both 75w90, but as far as I know 300 is fully synthetic oil while the motygear is what they call "technosynthese".

Hi

Yes, add the Gear 300, they will mix fine.
