A friend of mine has an 03 Tahoe and complains of poor gas mileage. I have
an 01 and get better mileage than his. Both are 5.3 liter plants.
City mileage: 17 (mine) vs. 14 (his)
Is this because of the "Flex Fuel" change to the engines? Here in Houston
there are no "Flex Fuel" stations. So it's kind of an overkill to sell those
