8 Common Causes Of Poor Fuel Economy
Is poor fuel economy wreaking havoc on your budget? When a full tank is taking you half the distance it used to, it’s time to take a look at what could be impacting your careful efficiency.
Poor fuel economy is a sure sign that your vehicle isn’t running at its best and you need to establish where the problem lies. Unfortunately, it’s not always easy to find the source of the problem because many factors can play a part. In addition, the issue could be caused by a number of things, so it takes patience to get to the bottom of your car’s gas-guzzling ways.
Here are a few of the factors that influence your car’s fuel efficiency:
Defective fuel injectors
If your fuel injectors are faulty and insufficient fuel is being injected into the engine, your car won’t run efficiently. A less efficient engine means increased fuel consumption.
Clogged air filters
Air filters and oxygen sensors ensure that the ratio of air and fuel going into the engine is correct for optimum performance. If they’re clogged or damaged, the ratio is affected, which can damage your engine and will increase the amount of fuel your car is using.
If your tyres are under-inflated, it affects the car’s traction on the road, which in turn affects fuel consumption. Improperly inflated tyres can increase consumption by up to 20%, as well as damage to your suspension, so check them regularly.
Faulty spark plugs
If the spark plugs in your car aren’t sparking correctly due to wear and tear or damage, it affects combustion. The result? Increased fuel consumption.
The wrong oil
If you aren’t using an oil that reduces friction or the oil recommended by the manufacturer of your vehicle, you could be paying the price with poor fuel economy.
Idling for too long – more than 30 seconds at a time – has a severe impact on how much fuel your car uses. Ideally turn your car off or put it in neutral to save fuel and, of course, money.
Bad driving habits
If you’re one of those people who enjoys revving hard and taking off at speed, your exuberance could be the cause of your car’s thirst for fuel. Avoid aggressive acceleration and revving.
Poor fuel economy could be caused by one or a combination of these factors. Consult the experienced team at ABS Auto to improve your car’s fuel efficiency.
