Daves comments are not entirely in context here. We change our plugs very regularly, and most of us pre-mix, and turn our injectors off.

Andy made good points about the relative chemistry differences above.

Syn oils have much better and more linear behavior regarding heat. True, they might not SINK heat as well, but they maintain viscosity at much higher temps than Dino oils. Don't forget, the number you see on your gauge is an average, if you will. Things are much different at other points (seal points, bearing points), and proper viscosity is critical there.

Our engines are pretty lightly stressed compared to other race motors, and we should have plenty of cooling reserve.
