I have heard many stories about engine oil in our trucks. I wanted to hear from you guys, what you run in your engines. I currently run 15w40 motorcraft oil and all filters and change every 5000 miles. Would like to go with T6 synthetic. Anybody had any problems with T6? plug oil coolers? recommended change interval?

T6 is a good oil, but not for much longer oil change interval. Even PAO's are shearing in the 6.0, including Amsoil according to analysis. Most oils are going to be just fine till 5k. I am testing an oil now in a truck that is seeing severe duty, Ill know more after they put some miles on it, but for the most part, just change it often.

I've been running T6 for about 4 years now, sometimes with Rev-X, and I've had no problems. I tried adding Archoil this time. Either way I still stick to changing it every 5K mi.
