This is one of the most common questions of new owners that do some spirited driving. An Oil Cooler will help drop temps and give you the flexibility to do spirited driving if you wish without the oil temp worry. This topic has been beaten to death and a simple search would have yielded numerous threads with the same conclusion.

These engines produce a lot of heat. On track even with an oil cooler I can hit 280F if pushing hard for several laps on a fast track. We're not the only cars without coolers, Corvette's (non Z06) models have a similar issue and can push oil temps to 320F and coolant temps to 260F.

I don't really notice a power loss until 280F when the ECU intervenes. Prior to that there is a slight loss of throttle response and perhaps a very slight loss of power as the ECU adjusts the timing.

Your lucky you are not getting pounded by more people.

well i just thought it would be more convenient to get feedback from people that already understand this issue instead of going to the forum like a textbook. i did mention i already went through some posts but just wanted some personal feedback with my particular situation. For those who are bothered by me posting another oil temp thread, im sorry. I didn't realize there were THAT many posts already made about this.

We are trying to help. But that's the best joy of this site is research. That's majority of what I do. Page after page. Which in turn I've learn butt loads of goods along other people mistakes. That's why I haven't had a issue with my car yet.

Why you should not buy a 370Z

Same thread??

My non Z06 C6 had an oil cooler and it still ran 250-260s, people need to stop flipping out like little kids. I think water temp it got up to 230 or 240F.

Your 370 is not outrunning a GTR at 200F or 280F....

Just as a heads up, the OBDII system doesn't read the oil temp as one of its parameter. If you lose power, it's most likely because of the variable timing or car pulling time due to intake temp. It really isn't directly related to oil temp.

The ECU most definitely does read the oil temps. How else does it know to enable the two stages of limp mode at 280 and 300? Whether it uses coolant or oil temp to pull timing is currently a mystery to me, but it has to be doing one or the other well before 280.

Yes you are right the ECU does read it, but I meant it doesn't seem to have any direct correlation to pulling timing back like it would with coolant and air intake temp. Someone did mention it can change the VVTL, which is possible. Still from what I can see, ECU doesn't pull timing based on oil temp. Of course as oil temp goes up, your coolant and air temp already went up.

Remember limp mode is a rev limiter if I recall correctly, it doesn't just pull power

I cant drive the car in hot summer vegas weather..it easily reach 250F by that time i do feel a bit lag..oh well, still driving it though..

tjlazer · 08-08-2011, 01:50 AM

I hit 220 the other day doing some spirited driving on the highway in the scorching Seattle summer heat of 75 degrees. lol

I only flip out when the ECU shuts me down.

And for the record I did outrun a GT-R at NJMP by 0.4 seconds, granted he was on the stock tires and I was on slicks.
