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 vehicles here.
Comments?
