Default Re: Mileage

We all own a Hummer because we love the truck and not because it gets good gas mileage! If you only put about 7,500 miles a year on your truck it would take about 5+ years to recover an investment of $2,000 today if you could achieve a 3 mpg improvement.

The best improvements in mpg will be achieved by how we maintain and drive the truck: don't load it up with excess baggage and weight, use cruise control on open roads, accelerate at a reasonable rate, coast to stops instead of braking, check tire inflation often, don't run oversized tires, change oil, air filter, etc. often.

Probably the only aftermarket item that will improve mpg is a cold air intake. Not sure how much but maybe there are test that have been done that you can Google.
