I was doing some research on recommended oil temp's in race applications and
got the following advice from a technical contact at Valvoline. I though
the list might find it useful, so...

>Mr. Evans,
>If you are using the Valvoline SAE 20W-50 Racing Motor Oil, 225 deg F
>should be no problem. Most cars on the road today have a 190 deg F
>thermostat. The oil temp is usually 30-50 deg F higher than the coolant
>temperature that the gauge in the automobile is measuring. The oil has to
>reach 212 def F to burn off condensation and other contaminants in the oil.
>If 225 deg F is all you are seeing, no problem. Keep on going. If the
>temperature get above 260-270 deg F, back off. Thank You.
