Going to change my gearbox oil, car has done 65k miles, 5 1/2 years old. Been searching a lot over the last few days for an appropriate oil and it seems a bit of a mystery.
So far I've found these three 75W-90 oils that seem closest to OEM:
Shell Spirax s5 ATE
Mobilube PTX
Mobilube SHC
The first seems to be the OEM oil from what I can see and the second is the only mentioned in the PET, although only for the front diff on 4wd cars. And they seems impossible to get hold of in the UK in anything less than 20L containers.
Mobilube SHC seems to be the only option for me that's closest to OEM? (I'm not completely discounting other makes Redline, Motul etc but just don't know anything about them.)
Is it suitable for the gearbox? I'm hoping the 2nd gear change when cold will improve slightly because its bloody awful at the moment!
I'll also do the very occasional track day.
Any info would be great.
