There are many reasons that can cause your car to consume excess fuel.High fuel consumption simply reveals that your car is not running as efficiently as it should,which also implies that you are losing money because you keep filling up more often.

Here are some possible reasons your car is using too much fuel 

1)Incorrect tire pressure
It’s also one of the easiest things to correct. Make sure to use the manufacturer’s recommended pressure levels stamped onto the driver’s side doorplate and not the “maximum pressure” numbers shown on the tire itself.

2)Bad oxygen sensors and Air filters
They can reduce your fuel 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.

3)Spark plugs
They are responsible for igniting the mixture of fuel and air in your engine. If they misfire, or are working poorly, this can affect your fuel consumption in a negative way.

4)Bad fuel injectors
It is responsible for putting fuel into the engine. If there is a leak, then less fuel will make it to the engine, and then in turn make it run less efficiently.

5)Air conditioner
A lot of fuel can be wasted in powering the system when used frequently.If the weather is not too hot, consider turning off the air conditioner and drive with your windows open. At higher speeds, close the windows to reduce drag.

A.c uses fuel and having the windows down causes drag, which uses up fuel too.Here’s what to do
At low speeds, the fuel used to compensate for drag is less than the fuel used to power your a/c, so open the window.

6)Idling
Idling is when you have your engine on, but you are parked and not moving. Common places where this occurs is when you are trying to warm up your car,while waiting to pick someone up or when stucked in the traffic.30 seconds is enough to warm up the engine.

7)Motor oil
The engine oil can also affect your fuel mileage by 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.

Overall, these are the major reasons why your is consuming more fuel , but the list goes on even further than this.
