Traveling 400 miles in Texas with one thing in mind. Economy. I was driving the family car, a '02 Tahoe (14/17mpg with a Vortec V-8) and gained a mere 3 mpg. I kept the speed low, sped up on downhills, coasted up hills, and pulsed to an extent. I kept the A/C off (to the great chagrin of my mother) and all vehicle conditions were ideal, although stock.

In 98 deg. Texas weather, is it advisable to block the grille? I understand AC won't work well, but hey, $4.00/gal? Crazy becomes wise at that point.

What did I do wrong? Why only 3 extra MPG? Should I have P&G'd more? With the auto tranny in the Tahoe, it decelerated rapidly with no gas, and popping it into N every 8 seconds for 6 hours seems a very bad idea. Advice?

Thank you for the 3 mpg, but I want more!
