High performance Holdens in Australlia appear to use 10W-40, 15w40, 15W-50, and 20W-50. In the same exact LS1 motor.

As mentioned in other posts recently, the factory fill and recommended oil for HSV Holdens is M1 10w30, which as others have said is a little thin imo. The LS1s down here seem to suffer the same piston slap and oil burning problems they have in the USA.

I thought in one of the BB's that folks were running Mobil 1 5W-50 (Not available in North America), or a regular 15w40/20W-50, to minimise the oil burn/piston slap issues?
