Hello Jack

How are you doing? Is there any error code present in the vehicle at the moment? Here are the possible cause of why we have bad mileage.

1. Having bad oxygen sensors and air filters can reduce your gas mileage by up to 20%. The oxygen sensors help keep the proper mixture of air and fuel, and having this off balance can be inefficient. The air filters can get clogged and simply need to be unclogged to fix the problem. Air filters need to be cleaned so that the engine can work at its peak performance.

2. Your spark plugs are responsible for sparking combustion in your engine. If they misfire, or are working poorly, this can affect your gas mileage in a negative way.

3. Having bad fuel injectors can cause bad mileage. This is because the fuel injectors are responsible for putting fuel into the engine. If there is a leak of some sort, then less fuel will make it to the engine, and then in turn make it run less efficiently.

4. The type of motor oil that you are using can also affect your gas mileage up to 12%. You want to use motor oils that are high in reducing friction. Either use a synthetic oil or the oil that the car's manual recommends.

I'll be going out and please leave your response. I'll get back to you as soon as possible. You have a good one! Thank you
