The price of gas keeps going up. Here are a few do’s and don’ts to help you save money.

DO:

* Do inspect your vehicle's gas cap. A loose or damaged gas cap can cause your gas to vaporize.

* Do keep your tires properly inflated. When tires aren't inflated properly it can cost a mile or two per gallon.

* Do replace your vehicle's spark plugs on a regular basis as recommended in your owner's manual.

* Do replace your vehicle's air filter on a regular basis. Replacing a dirty air filter can improve gas mileage by as much as 10 percent.

* Do observe the speed limit. Gas mileage rapidly decreases at speeds above 60 MPH.

* Do combine errands into one trip. One longer trip is better than several short trips.

* Make your car's alignment is maintained.

DON'T:

* Don’t be an aggressive driver. Aggressive driving can lower gas mileage by as much as 33 percent.

* Don’t let your vehicle warm up for more than a few minutes. Sitting idle gets zero miles per gallon.

* Don’t carry unneeded heavy items in your vehicle. An extra 100 pounds can cut fuel efficiency by a percent or two.
