So after a lot of people saying on the GTO FB page that royal purple should be given a miss, I decided to drop the stuff out of my diff and replace with Castrol syntrax and some Redline modifier and what a massive difference, so much quieter and no knocking, should have done it when I replaced last year won't be using royal purple ever again.

I noticed same, Royal purple is a no no caused me problems when used in my MonaroAde
My diff was knocking a bit,so i changed the oil (castrol)and it went quiet,but wasnt locking reliably. I bought a kaaz to be sure.
When I pulled the stock diff carrier out this is what greeted me. I didnt see any white metal in there ;-)
So yea I was glad I bought the kaaz, It was very harsh at first,but now its bedded its lovely. 2nd car ive put a kaaz in.

Would this be Castrol Syntrax 75W 140 by any chance? Can you give a clue as to how much Redline modifier you added please? Tamfp4073 said:

It attacks the white metal parts in the diff that causes diff problems
Well I've never heard of that before, I wonder if that's affecting my Truetrac?I might just change the oil to an old mineral type and see what happens.
I've use Royal Purple in my Monaro for 65k miles and it's still running sweet at 113k miles.
Monkfish were users of Royal Purple - good enough endorsement for me.
to Royal Purple.
