Hi everyone, I need some advice from you knowledgeable people. Which oil do you recommend for the gearbox, front differential, rear differential.

The book says 75W90 GL5. I guess fully synth.

Also if you are there Iggy, did you change the oil for the gearbox and diffs. when the engine was re-built ? Have not done many miles since the re-build so may not need to change the oils if you did it. 

Still loving the car Iggy !!!

Hi

Yes, you need a 75w-90 GL5 oil.

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

The Millers CRX NT, Motul Gear 300, Red Line 75w-90NS and Gulf Competition are ideal as top end options. The Millers TRX Synthetic/EE Nanodrive, Mobil SHC, Castrol Syntrax Universal Plus and Valvoline Synpower TDL are good, but a step down from the top oils. Fuchs Gear Syn, Motul Motylgear, Millers TRX Semi and Castrol Universal are good, cheaper options.

Cheers

Tim

Thanks oilman, from your recomendations I guess the RB320 has non-limited slip diffs in both axles ?

Also can I use the same oil in the gearbox and both diffs ?

best regards

Hi Sheena

As far as I am aware, it has mechanical rather than plated LSDs, mechanical diffs don't need LSD oil.

Yes, you can use the same oil in the gearbox and diff.

Cheers
