We have discussed several times in the past the gains in fuel mileage that can be expected from different weight motor oils.
While wading through the NHTSA site I found a list of various technologies planned to meet the tighter Light Truck CAFE standard in 2005-2007. I assume the reference oil was 10W-30.
1% 5W-30
2% 5W-20
3.1% 0W-20
