Have you ever considered how to get more miles per gallon of gas or diesel? The main tip for improving gas mileage is to stay on top of your vehicles maintenance. We all lead a busy life and it is easy to forget vehicle maintenance and by forgetting we often do not get better 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.

It may be found that your diesel engine has a defective glow plug or your gas engine has a clogged or dirty fuel injectors then your engine performance will be poor.

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.

A weak battery or alternator can affect your charging system putting more of a load on your engine and decrease your gas mileage.

Most tuneups done in a reputable shop will result in an increase in gas mileage. You could expect to see increases of 40% if certain components are replaced.

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.
