7 Causes of Poor Fuel Efficiency

Obviously, it's been a rough year at the gas pump. Fuel prices are higher than ever and every fill-up is a bit painful as you watch the numbers go up so quickly. This is why fuel efficiency is so important. Whether you drive a hybrid or a gas-guzzler, you want to get the most out of every gallon.

If you are noticing a dip in your miles per gallon (MPG), there could be a number of different automotive issues hindering your fuel economy. These are problems you might want to be on the look out for and ready to address with necessary maintenance or repairs. Some are simple fixes. Others will need some professional attention from trained mechanics.

Here are a few common causes of poor fuel efficiency:

1. Tires

You will want to maintain proper air pressure in your tires to help maximize fuel efficiency. If the air levels are uneven or too low/high in all the tires, you may see a dip in your MPG. Tire tread depth and evenness can also affect fuel consumption. Keep your tires healthy and your gas tank will benefit.

2. Wheel Alignment

Misaligned wheels can also hurt your fuel economy. Your vehicle basically has to work harder while it's driving, so that is naturally going to consume more fuel. Get your wheel alignment checked regularly and adjusted as needed.

3. Exhaust/Emissions System

Your vehicle's exhaust and emissions system plays a critical role in fuel efficiency. If you have problems with your catalytic converter, muffler or any exhaust leaks, your engine won't run as smoothly and you will burn more gasoline.

4. Fuel System

Naturally, the fuel system itself could be to blame if you are losing mileage. There could be contaminants in the fuel tank or clogs in the fuel filter or lines. You may be overdue for a fuel system service.

5. Engine

Of course, any engine issues will likely lead to a loss of fuel economy. Keep up with your oil changes, replace worn spark plugs and keep your engine healthy to prevent wasted gas.

6. Transmission

Your transmission could also be a reason why you are losing fuel efficiency. Smoother shifting and torque control mean you are operating the vehicle more efficiently. If the transmission is struggling, then it will make the engine and everything else work harder more more fuel will be consumed. 

7. Other Factors

Sometimes the issue is not necessarily mechanical. The driver may just have a "lead foot" or there could be external factors at play. The more you drive in stop-and-go traffic or up steep hills, the more fuel you will burn. Driving in excess heat/humidity or freezing temperatures will also hurt your fuel economy. Pay attention to how, when and where you drive. There may be simple things you can do to help conserve a little gas each month.
