Change viscosity? High mile 4.6 2V burns oil

He lives in PA, where I have personally saw all 4 seasons in a day. Good reason foe me

Well then, how do the folks living in Canada get away with using my suggestion?

I’d use an ACEA C3 in 5w30 long before I went out of my way to toss some shekels into GM’s pocket. The M1 0w40 is a solid recommendation as well.

Not to mention going out of spec I’d rather go for the usually more stringent euro standards than Dexos.

Why all the seasonal changes? Use Euro 0/5w40 year round.

Didn't think it was all that much but I run 10w40 as it is cheaper with the frequent changes I do when towing. I'll change the oil 2 to 3 times when towing as we go across the country or close to it.

the Ford 4.6 is not know for being an oil burner. I would spend 5 dollars and replace the PCV valve on the passangers side valve cover first. This is a very well known issue. I bet that is your issue.

I’ll try 30W this time around. The spirits are flowin brother!!!

For what it's worth, I permanently moved to 5W-30 about 3 years ago for the higher HTHS.
My engines run even quieter and smoother than they did on the 5W-20 the vehicles were speced for.

I always ran 5W30 in my 4.6 2v.

Same.
