Not 100% sure yet, but with the technology of the ecoboost motors being very similar to diesel motors the T6 might actually be of better use in our motors.
This is just a thought no proof or anything of that sort, but the diesel oils are designed with a strong cleaning package to reduce or hold soot in suspension.
plus they are designed with a thought to strong sheer resistance and a few other points. Plus its A LOT CHEAPER

5 gallon jug is $20 and right now there is a $5 mail in rebate, and 1 quart bottles are $6 to $7 dollars, plus a 8 dollar filter puts you cheaper than the oil change specials for the normal mobil 1, Castrol Edge ect. Considering you still have to buy an extra quart of oil that puts you over $45 dollars usually.
I have no problem running a 0w-40 or 5w-40 in the summer at all. And only limited hesitation in the winter.
