The guys at Canton made a good point when I spoke with them today. Thier oil t-stat is set at 215-degrees. Why? So that any water (ie moisture) in the oil will burn off.

They said that this is especially true of cars that sit alot (like our cars) and they aren't fond of the lower temp t-stats.

The hard part is getting the oil to 215*. Unless the coolant thermostat is 195+ and the engine is run hard, it may not get there very often. If the thermostat is a bypass design (MOCAL, CV, etc.) then some oil will always go through the cooler.

Funny.. mine gets there all the time the way I drive.. lol

Around town my oil temp is fine.. it's only when really flogging that it goes up and I need a cooler.

heck, at Optima I think it hit 260-270 with Dave.. the year before (no cooler) it almost hit 300.

To be honest, if you're running synthetic, 215 is a good temp..

How many quarts are you running in Penny?

That pan is around 6... plus the lines, remote filter and cooler.. so maybe a bit less than 8
