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.
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.
Depending on what is discovered or found during an engine diagnostic you could end up having oxygen sensors replaced or other sensors that help monitor your engines performance and emissions to help it run at peak performance.
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 properly performed tuneup can in most cases result in an increase in gas mileage. It would not be unusual to see mileage increases of 40% in a worse case scenario.
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.

I like being able to research new ways to save on gas and I think you make a good point here. Another way, that is easy and cheap, is to keep your tires inflated to max air pressure. I check them each time I fill up and have seen an increase in 4-5 mpg over the last month alone.
That’s a great point. It’s so easy to forget the little things that make a big difference over time. Underinflated tires are a major drag on fuel efficiency, and just checking once a month is a great way to improve gas mileage and an easy way to save money.
Not only that, but you’ll know a lot sooner when you have a slow leak or a damaged tire. It’s far too easy to pick up a sharp object like a nail in the tire and not even know it. That happened to me on my Rendezvous the first month I had it. By checking your tire pressure, not only will your fuel mileage improve, but you’ll end up with a much safer vehicle in the long run, and make your tires last longer too.
