Seriously?

Modern motor oil can survive way more than 240F. They are running warmer and warmer for emission and fuel economy reasons. Of course as the temperature goes up, it does deteriorate quicker. I am with the OP that it is in your head on this one. Also if you look at the ECU fuel settings, it doesn't pull timing from oil temp. It does it only if your engine is so hot that it soaks the air flow meter's temperature sensor, I highly doubt oil temp at 240F is enough to soak your engine by that much unless you are sitting still

Continuing to increase oil temps will only amplify the problem. Over the past couple weeks, my engine temps have crept northward of 220* which does not sit well with me. I typically baby my car, but even with my driving style, I still get oil temp spikes up to ~240*. I will be looking into getting an oil cooler put on my car in the coming weeks to alleviate this problem. While an oil cooler may be a necessity, it will help with peace of mind.
