Jeep had highway issues, i had to stay in OD 3250rpms the whole time to be at just 65mph. Used up half a tank. The temp gauge never went past 215, but i saw smoke and pulled over to see oil pissing out the rear main and my overflow tank boiling coolant. Let it sit to cool off and was fine. Didn't act like this on the way back either, steady 2250 rpms at 65 all the way, barely used a quarter tank.
