Redline is the best, i just put it in my car...

[wld808]

i made a deal with redline at my workplace and we be stocking it within the next couple weeks.

very rare to find suppliers in syd for that stuff.

i just used castrol epx80w90. seems to work fine for me

i did a search on this a couple of months ago and found most guys in here to be using redline.

i did some reading and research on my own as well, looking @ neutral websites and see what they have to say abt redline and its was always positive.

i went ahead with it and no regrets whatsoever

expensive but well worth it. its gunna stay in your diff for 2 years so might as well get something top of the line.

Is there a guide anywhere on how to actually change your diff fluid?

Cos i have a feeling mines never been done, and want to do it

[Duncan]

no guide yet, so take some photos when you do it

Theres just the usual filler on the top at the rear of the diff, and a plug on the bottom. make sure you can open the filler plug before you let all the oil out....

takes about 1.5litres of 80w90 oil.

i can't get any Redline up here in Bundaberg

i've tried all over

[knore]

Ok so how do u get the fluid in if the inlet is right at the top?

The filler is on the top and the drain is on the bottom...

But you don't want to drain all the oil only to find that you can't open the filler...

[EnricoPalazzo]

most bottles have a filler in them which u can pull out and use to fill it with. Otherwise u need a oil pump

[Steve]

filler hole should be on the side of the diff - just pour it in until it comes out the hole - then its full.

I use castrol 85 weight, works fine (no dramas yet). I have a 2 way diff, so I am a bit wary of oils like shock proof.

will better fluid help a sometimes open wheeling diff?

[strutto]

If your talking about the stock 33 diff, I wouldn't of thought so considering the viscous coupling and fluid is contained seperately from the actual diff oil...

[EnricoPalazzo]

yeh talkin about stock viscous diff

[Busky2k]

Yup strutto is correct, it doesnt matter what fluid you use, because a viscous coupling unit is not affected by the oil so you can just use any GL5 rated oil as you please. Mechanical/clutch style diffs in commodores etc are sensitive to the fluid's coefficient of friction so you must use a specified differential oil in those...
