I've also read where you should wait until Oil Temp is @ 92C before hammering it.

Fastest way to do that is drive it quietly for a few kms, then stop and switch off. Start again after about 5 minutes 9or so). Temp will rise much quicker.

Drove a 6R GTI the other day, 2km to servo, stop/shut off/refuel then about 2 km to the destination. Oil Temp was at 75C when I arrived at destination.
