I Killed My Rb25... Again:(

But everybody, even Redline recommend to use their Shockproog oils in gearboxes. All sorts of claims about helping synchros etc. But look at their website (US) and it says not to be used in synchro gearboxes...but Aus says to use it. Plus too many tales of things going bang.

I will stick with Castrol for everything, its just what im comfortable with and to date has been good to me The only other engine oil i have used is Mobl 1, but cant find anywhere is Vic that sells the higher viscosity that it is available in

aussie site is rubbish. i have a number of emails form redline in the US and form the BITOG forum. Not a good idea, and hence why so many people have issues. their shockpoof has to many friction modifiers for the GB thats the issue. I would use their MT90. Nothing wrong with Syntrax and Syntrans GB/Diff fuilds from castrol good stuff.

Not a fan of their engine oils.

German Castrol is top shelf, only import though for us. GC is rated as one fo the best and has extensive UOAs to back it up.
