I have been running 5W40 full synthetic on it, just serviced it though so we'll see if it makes a difference. Truck hasn't been plugged in yet this winter, it has been getting colder but anything below -10C I plug it in. Its not as bad once it warms up.
EGT issue is only when I'm pulling a hill loaded. Empty I couldn't even get close to 1200. Cruising on flat ground with a trailer usually sits at 800F, without trailer 600F. It does take a good hill to hit 1200F with a trailer behind.
