No probs. I'm 99.9% sure that's the right stuff, cos that's whats going into my car this weekend if all goes to plan

Yes, Castrol SAF-XA is the correct oil.

There's only one grade of the stuff so providing it's SAF-XA you can't go wrong. It also contains the friction modifier additive so there's no need to add that.

thanks but were can it from

Got mine from Repco. Other places would stock it too I'm guessing

Yeah. Any of those types of stores...
