What Engine oil do you guys use in your 6.7's? is it worth the Extra $$ to use the Ford XO-5W40-5QSD SAE 5W-40 Full Synthetic Diesel Motor Oil. they sure are proud of that stuff it's quite a bit more $$ then the good ol Rotella T6. any pros and cons?

I use Rotella T6 with Archoil AR9100, seems to be working great for me.

Some like the Vavoline 5w40 full synthetic oil that is on sale at NAPA for approx 19 a gallon.

One benefit of full synthetic oil is cold weather starting.
