[Vwdiesel] Air-cooled and diesel oil?

   There wasn't any change in head temps, just oil temps. I've read that before
about synoil supposedly not picking up the heat -- total nonsense, I think. If
it were true, head temps should have gone up. The bottom line is that virtually
*all* racing cars use synoil because the reduced friction gives them more power,
and reduced friction also means less heat.
