These two tips together can provide a 14% boost in your miles per gallon, effectively reducing what you pay for gas.
Low tire pressure can reduce your gas mileage by up to four percent, as well as uneven tire wear that will cost you later. Tires lose pressure over time, up to 1 psi per month, even when they are in perfect shape. Also, changes in temperature can cause a drop of 1 psi for every 10 degrees.
The right pressure for your tires can usually be found on the data plate inside the driver's door jamb.
The second tip ? ...
Dirty air filters can cause your gas mileage to drop up to ten percent. And, they usually cost less then $40 to replace, sometimes under $20. You can do it yourself, or most oil change facilities will install them for a nominal fee.
Can you afford to be paying for 14% less gas mileage than you should be getting ?
