Increasing Miles per Gallon

by Pete Roberts

How do you get more miles per gallon of gas or diesel? The number one factor for increasing gas mileage is to keep up on your vehicles maintenance. With everyone leading busy life styles it is often easy to overlook car maintenance and by doing this you are often failing to get the best gas mileage.

When was the last time you vehicle has had a tune up? If it has been a few years or your vehicle is running or idling a little rough or your miles per gallon has decreased you may be wanting to schedule an automotive tuneup.

A tune up usually involves a diagnostic engine test. Spark plugs and air filters are often replaced and sometimes corroded or cracked or defective spark plug wires are replaced. Often gas metering and airflow adjustments are made.

If your diesel engine has a defective glow plug or your gasoline engine has a blocked or dirty fuel injectors this can further deteriorate engine performance.

It may be discovered on an engine diagnostic that you have a faulty oxygen sensor that needs to be replaced or other sensors that help keep your engines performance and emissions at optimum levels.

You may also find you have a weak battery or alternator affecting your charging system and this can have an effect on you vehicles mileage.

A complete tuneup can usually result in getting more miles per gallon. It would not be unusual for a vehicle worse case that has a bad oxygen sensor to get better gas mileage of 40%.

If your looking to do it yourself on a few improvements properly inflated tires can improve gas mileage a few percent. Replacing a dirty air filter can increase gas mileage up to ten percent. Adding a fuel additive every few thousand miles can help keep your engine clean but always check your owners manual before using additives. These are just a few items you can do at home or on the road that can help you get more miles per gallon.
