Check your tire pressure

Having the pressure of your tires inflated to the PSI indicated on the placard on the drivers door frame of your vehicle can assist greatly in increasing your mileage. Also increasing the PSI by 2-3 may assist as well. This works by slightly decreasing the contact patch of the tire to create less rolling resistance. HOWEVER it is not recommended to use the PSI stamped on the tire nor to inflate past 5 over on the placard (LT tires and load carrying trucks are an exception). Doing so can dangerously decrease the contact patch of your tire decreasing your grip when you least expect it as well as cause abnormal tire wear.

Cruise it!

If your vehicle has cruise control use it! We know in the mountains opportunities for that are slim but we can help our vehicle be more efficient by leaving earlier and not being in a hurry. You may work around the corner but those pedal to metal 3 miles will cost you in the long run. Take it easy and cruise keep that lead foot at home.

Wash your vehicle

Most people would be surprised how much washing a vehicle can help fuel savings. Vehicles are tested in a wind tunnel for drag. As you drive any caked up dirt, snow, etc disrupt the air flow around your vehicle and cause drag making your vehicle consume more fuel. So rinse your vehicle off every so often. And if you treat it to a wax the savings will add up even more.

Lighten the load

Always have tons of junk in your truck bed or trunk? Try seeing what you may be able to leave at home. The more weight your vehicle is carrying the more it has to lug around and the more fuel it uses.
