Is the magnesium a concern?
I've cut my consumption in half by switching to 5w30 in my expedition. I went from 1qt/2000 miles to 1qt/4000 miles in a very predictable and consistent way.
the only exception to this was the Pennzoil platinum 5w30. the consumption rate of that 5w30 was the same as all of the 5w20's I have run.
it is very worth your while to try a grade switch.
this is still the 2v engine in 2012, yes?
