- I added the SC at 150k, it has always ran like a champ, and these motors are known to handle moderate levels of boost without any issues, especially with appropriate fuel mods.
- I don't beat on the truck, but I didn't put the SC on it for looks. It gets romped on occasionally.
Thanks for the tips on the Motorkote, I will forgo that until I find an oil that helps with wear numbers. I plan on jumping up to an xW-40, does it matter much whether it's 0W, 5W, or 15W? I am reading conflicting arguments on that point. I'm not concerned with fuel mileage or any of that, maximum protection is my goal.
I’d recommend a full syn 5W-40 that is CK-4 rated. Delo XSP, Delvac 1 ESP, Rotella T6 are solid options and readily available.
An A3/B4 rated oil is also a solid option. 0W oils will tend to be lighter and less shear stable compared to a 5W oil.
