Ok ppl, i posted a thread about gearbox oil asking which one to use in my recently aquired Sti V-limited. After a lot of suggestions i thought syntrax would be good. Castrol Syntrax that is (also know as driveline). So went down to Halfords and found it but got a bit confused?

Is it: Syntrax Universal 75w90 ? the green top one-but doesnt say its for manual? it said PREMIUM gear oil.

but there was also another one with a manual g/box logo something: syntrax sm-5? that said SYNTHETIC gear oil and had a RED top.

if i get really impatient i may jus put some premium

which one?

 

As long as you don't have an adjustable center diff (not sure on the v-limited) you'll be fine with castrol syntrax drive line.

 

Driveline in my suretrac equiped 6 speed, works a treat (green top)

 

Thanks guys, yeah the green top one the exact name is 'Driveline Syntrax Universal' Grade stated on the back is 75w90 from Halfords at £10.99 for 1L, apparantly thats all I needed for a top up and have done it now with the aid of a small funnel (didnt even need a hose). I have heard that overfilling it is a good idea but i only topped it up to F on the dipstick. What do you guys think?

 

overfilling the five speed didn't seem to do any good on my old box (hence why I put a 6 speed in there) broke it in three weeks anyway.
Don't think any of us could "prove" it helps or not..

what do you use on a ra box with dccd? thanks

 

I'm def changing mine for syntrax on 6 speed, but wonder if I should leave silkolene 75w90 in my rear diff or would that also prefer Castrol? Its a R180 diff.

Cheers

 

i will be putting silkolene BOA 90LS in my rear diff and redline heavywhight shockproof in my gearbox,version 3 sti ra.
