Causes of Poor Gas Mileage

Suppose you filled up the car not too long ago, and you start it up expecting to embark on a long journey without running into any problems. Then out of the blue, you notice the car grumbling and slowly coming to a stop. You look down only to find the fuel gauge pointing at “E”.

Worsening gas mileage can be pretty irritating, especially if it has drastically dropped within a short period. You may have noticed that you’re stopping at gas stations more frequently than usual, which wastes not only your time but also your cash.

While decreased gas mileage is a natural occurrence for aging cars, it’s abnormal for recently purchased vehicles to suck up more gas than usual and could be a sign of a possible underlying issue causing your wallet to run out at a faster pace. 

Luckily, you can resolve many issues by taking proper measures and avoiding bad habits that harm your car. And by determining the causes of worsening gas mileage and eradicating them, your car- and mostly your wallet- will be very grateful for it.

1.   Underinflated Tire

A tire with low pressure is considered one of the most common reasons for lousy mileage. Thankfully, it’s an easy fix and can be easily avoided by maintaining a regular tire checkup every few weeks or so.

Your car automatically warns you when your tire pressure gets too low, but you might want to inflate your tire before the warning shows up. Low tire pressure causes the engine to burn through more fuel than usual, and the car will only warn you about the pressure when it’s way below the recommended level. So you might be unknowingly wasting gas due to a simple error.

2.   Faulty Ignition System Parts

Whether it is the spark plug, ignition coil, or plug wire, a faulty ignition system component can negatively impact the engine combustion, thus leading to lower mileage. The common culprit is usually a defective spark plug. If the spark plug isn’t functioning accordingly, it will cause the engine to misfire, leading to fuel going down the drain without being burnt and used.

Luckily, there are many signs that indicate if the ignition system is to blame. If you notice your vehicle experiencing rough idling, stumbling, and decreased engine performance overall, you might consider examining your ignition system. 

3.   Filthy Air Filters

Air filters provide the engine with a constant oxygen flow. For the car to “breathe” and burn fuel, you must occasionally replace these filters to prevent dust and dirt accumulation.

If the filters are clogged and filthy, the engine will struggle to keep up with the effort required to maintain the same speed, which leads to increased fuel consumption.

4.   Harmful Driving Habits

That’s right, flooring it when you see a speed bump or pothole, revving the engine up to seem cool, and driving around full speed as if your life depended on it shockingly takes a toll on your car’s health. So consider that the next time you decide to drive recklessly.

Smashing your car into a pothole head-on can severely mess up your wheel alignment and suspension, causing resistance and reduced gas mileage, while extensive braking and accelerating wastes a ton of gas.

5.   Wrong Engine Oil Type

Despite the popular misconception about heavy-weight engine oil being unable to seep through leaks, this type of oil can put a strain on the engine due to the increased friction in the engine’s interior. 

High-mileage engine oil, however, is used for both oil leakage and consumption and is considered the best option for various types of vehicles.
