1. Inappropriate tire pressure

Low tire pressure means more area of your tires touch the road, which requires the engine with more power, hence burn more fuel.

2. Inefficient oxygen sensors and clogged up air filters

They may cause up to 20% more fuel consumption than usual. The oxygen sensors work to make sure the air/fuel mixture gets balanced. The air filters can be clogged up over time. In this case, a simple unclogging service will effectively fix the problem.

4. Leaking fuel injectors

Fuel injectors take over the job of feeding the engine with necessary gasoline. When it’s leaking, less fuel will reach the engine, making it work less efficiently.

5. Abused air conditioner

Don’t always resort to the air conditioner when you can open the window to get fresh air instead, which is also healthier. At higher speed, consider closing your window to optimize the aerodynamics, resultantly reduce the drag that lessens the fuel economy.

6. Idling

Idling is when the engine is still on while the car itself does not move. People often do this when they’re waiting for someone, sitting in traffic jams or warming up their car. These may not cost much as you always think but in a long run it costs you a bunch. Remember, 30s is enough for your engine to warm up.

7. Old or low-quality engine oil

Good engine oil works to reduce friction in the engine. If your engine oil goes bad, it may consume 12% more fuel than usual. Check the car’s manual for oil change milestones and the correct type of oil.

We just summarise 7 most common causes of excess fuel consumption though, of course, there are still more factors adding up to the inefficient fuel burning. What do you think they are???
