Got a lesson in hot weather today. I rode inland about 25 miles from the central coast of California and hit temperatures of 105 degrees. Also got stuck with a group of fellow riders at a malfunctioning traffic signal and had to sit through 3 cycles of the light before we turned against the red when the traffic was clear. After going down the road for a few miles after turning at the signal, I pulled over and checked the oil temp. 255 degrees!!! And that's with an oil cooler. I'm running full synthetic but i expected better performance from the oil cooler. I guess it can only do so much even if you are moving.
