Choosing engine, diff and gearbox fluids

[Andy_Mac]

I know the engine oil needs changing so I figured doing the other two at the same time since there is no record of when they were last done.

These are what I'm looking at at this point, very open to suggestions.

Engine

Probably overkill but want to do things right with this car.

Gearbox

Rear diff

Thinking the same as gearbox unless there is something better to use?

I use the same one for the engine oil.

Front and rear diff i use castrol syntrax 75w-90. Smells so bad. But binding was gone which is good.

Think you can use the same for manual tranny?

[Andy_Mac]

Yea was wanting syntrax but couldn't find it in any bigger than 1L, might try repco tomorrow and see if they do the bigger containers

[seith_31]

I dont believe you'll get anything bigger than the 1l stuff...

Try to wait for specials. If not it gonna break the bank...

I used the multitrax oil in my old WRXs as it was recommended in the owners manual. Was pretty good, even cleared up some slow syncro's i had. Its what they use at the stealership so it'll be what my GTB will have in it now as well (50k service done at armstrong by pervious owner) still nothing bad to say about it here.

[Andy_Mac]

Sweet, might just give the multitrack a go then

I'm running Edge 5w-30 for the motor and Syntrax in both gearbox and rear diff.

I got the oil way cheaper than that price on special at Repco.
