Fuel Saving Tips
Use this tip at your own risk... I've found that inflating my tires to tire manufacturer limits (usually 6-8 psi higher than car manufacturer label) increases my mpg by around 8%. Charting my mpg for several years shows that when the dealer decreases my psi to car mfr pressure, economy drops until I re-pressurize to tire mfr limits. I don't recommend this for high center-of-mass vehicles such as SUVs (but you should consider getting a smaller, more fuel-efficient vehicle anyway).
