I've found that taking it easy on the gas, like pretending that there's an egg between your foot and the gas pedal, has done me the most good in terms of savings. I already get pretty good mileage so I feel sorry for you guys with your trucks.
Same here, well - not the good mpg, but taking it easy on the throttle. I baby this truck, the engine never goes over 2500 rpms. It makes me sad to waste all the power the 5.7 has, but I can't keep it if I don't baby it...
