The 0W30 improves mileage due to the otherwise lighter viscosity. Thinner oil, easier to pump through thus less parasitic loss. That being said, personally I'd be concerned with running the lighter oil. I know 5W vs 0W is not a huge difference, and the warm viscosity (30) is the same between the two. Having put together my share of motors, knowing what's going on in the bottom end puts a different perspective on the need for oil pressure
. I'm sure the 0W30 works fine, it just wouldn't be the place I personally would go to increase mileage. And for the record rjdelp7, nice ride! it's not typical that we see a 1st gen Expedition in that condition in the north east
