Anybody know how well this oil performs in a 6.7L Ford engine? With winter coming, I need to dump my 15w40 and go back to 5w40. I'm thinking ZDDP levels aren't high enough to satisfy Ford's spec. If so, what do you recommend using as a ZDDP additive to make the oil more stout.
I got 10 gallons of the stuff at a decent price and usually use T6 5w40 but that stuff is scarcer to find than a conservative in California. I have plenty of other turbo'd non diesel engines to use this stuff in if you don't recommend it but would like to give it a shot even if it needs some additives.
Thanks,
Drew
