I wouldn't worry about it. That temp is right in line with what I see in mine. I've been sending my oil off to Blackstone for analysis at each oil change, and the oil reports are coming back with no issues. The engine and the oil seem to be holding up just fine.

@extrashaky most people don't see the coolant temp gauge go up even during a 20 minute track session in the heat.

LOL I do UOA too! Mine always seem good too!

Was out at Buttonwillow Raceway this past weekend and even in the later sessions where ambient air temp was 102 degrees, with the car getting a full flogging, the coolant temp gauge needle never budged from it's usual place. I knew coolant temp had to be warmer; just figured the gauge was broken until I read this thread.

Many people start freaking out at oil temp over 200F for some reason. It NEEDS to get above the boiling point of water so it can boil off the contamination.

I disagree with this. Water does not need to be boiling for adequate rate of evaporation. Case in point - oil cooler thermostats are generally designed to maintain oil temp around 180-185 degrees Fahrenheit.

...but 220 is no biggie as long as pressure doesn't drop off. I don't know because I still don't have a pressure gauge

Like the other guy said it boils off as it gets close to 212, it doesnt just happen all at once. I just dont like how the ECU pulls power (I read that somewhere dont quote me, but my butt dyno seems to feel it, although it could just be AIT's getting too high in traffic aswell)

Any thermostat will open earlier than the desired peak temp to head off temp spikes. Local heating of the oil is going to be higher than what the overall temp is going to be as well, but getting the oil good and hot every so often (in my case, usually daily) is far better than having it cold. Yes of course there is such a thing as too hot, but the average person isn't going to see that outside of track use.

Most cars will pull timing a bit when things get too hot. You're usually going to have this stuff step in from coolant temp or IAT first though. Never had a car that didn't hate the hot ass summers around here...
