For comparison's sake, most modern trucks manage between 5.5 and 6.5 mpg. For most long-haul truck drivers, an increase in fuel economy of 54 percent would equate to a savings of around $25,000 per year at current diesel prices.
I have a 1997 Grand Cherokee Laredo with the straight 6 and the Quadradrive AWD transmission. The truck is bone stock and I'm currently getting roughly 18 mpg on the highway. I drive 80 miles a day for work and was wondering if anyone knew of ways to improve on my gas mileage.
