hi all just joined sau and got my new toy last weekend and i am in the hunt for some info but i will be using penrite hpr 15 on my r33 gts-t for its wide range of protection i used it on my old now 19yo r31 and no oil use and over 350,000ks
but and used it on my 2 cars before that (turbo coridas) they wernt the best but they lived till io sold them
well what is needed is a thin oil which flows easy hence as many have said the 0-20 and less range but not breakdown on high heat like a turbo and aussie conditions are as hot as they come as we all know so 40-60 range is needed for best protection .......
someone correct me if i'm wrong so i use hpr 15-60 becasue it does both well and only about 30 bucks for 5 ltrs
i seen this towards the front of the thread
Engine: Shell Helix Ultra (Synthetic) 15w-50 or 5w-40
Man Tranz: Shell Spirax CX 80w-90
Diff: Shell Spirax AX 80w-90
Power Steering: Shell ATF Dexron III
this written eariler in this thread and i would be thinking go a straight 80 oil for the GB for that should lead to a smoother shift
so this weekend its getting a total fuild change for some of this stuff could have been in it since factory so its goin to be engine, GB, diff , clutch, brakes , power steer this will cost me around 100$ but it will be ok for a will know its got good clean oil everywhere
and stageagirl oil $35 and $10 for a filter
