The track folks love this stuff so figured I'd give it a shot for an HPDE in a few weeks...won't be hot but the VW MQB turbo 4-bangers run hot and have high oil temps in general and this stuff may help. I just removed the same volume of G13 coolant from the expanstion tank, added the VP product, and let it run with the heater on for 20 minutes after it was already warmed up.
