Why am I getting so little MPG? ›

Key Takeaways. Old or dirty air filters can reduce engine efficiency, causing poor gas mileage. Faulty oxygen sensors can lead to incorrect air-fuel mixtures, lowering fuel efficiency. Underinflated tires increase rolling resistance, reducing fuel economy.

Aside from mechanical issues, other factors can affect gas mileage. Miskelley says bad alignment, improperly inflated tires, poor tread and driving habits can make a difference in how far a gallon of gas goes. "Poorly maintained tires can cause your car to pull harder and do extra work to get going," says Miskelley.

A good MPG is one that allows you to cover a good distance on the least amount of fuel. A good fuel consumption figure for a used car is around 40-60mpg. Cars that can achieve 40mpg are likely to help you keep fuel costs low, and anything above this is even more impressive.

The EPA says its test results are almost always very close to the automakers' numbers. When they don't match, a long discussion ensues. According to the rules, if the EPA retests a vehicle to assess an automaker's results, the fuel economy should be within three percent.

Yes, wheel alignment can significantly impact fuel economy. Proper alignment reduces rolling resistance, allowing your car to move more efficiently and consume less fuel. Misaligned wheels create additional drag and force the engine to work harder, thereby increasing fuel consumption.

If you have a clean fuel filter, better gas mileage will often follow. The reasoning is not quite the same as that with the air filter, but the common principle is anything other than gas or air in your combustion cycle will hurt your engine's efficiency.

As an engine ages, fuel economy will decrease somewhat. However, in most cases, this decrease in fuel economy has less to do with the age of the engine and more to do with how many miles you've driven and whether your vehicle has faulty or worn engine components.

At what speed is mpg the best? ›

Midsize conventional gasoline cars achieve their best fuel economy at 55 mph. The fuel economy of midsize conventional diesel cars declines gradually from 45 to 55 mph and then drops quickly thereafter. The midsize hybrid electric vehicle loses efficiency more evenly between 45 and 75 mph.

No, any fuel efficiency gained using premium fuel would stem from engine performance, not the gas itself. Buying premium gas won't have you visiting a gas station any less frequently, especially with a standard engine not designed to take advantage of premium gas.

The truth is, wherever you go and what kind you get can make a big difference in how well your vehicle runs. Not all gas stations hold themselves to the same standards, and there can be a significant variation in how they treat the fuel in their tanks and where they get it from.

The mpg figure simply refers to the number of miles you can drive using one gallon of fuel. As a rule of thumb, an efficient car will do more than 60mpg. Anything more than 50mpg can be regarded as decent fuel consumption, but if you're getting less than 25mpg, efficiency probably isn't your priority.

You might be purchasing a higher grade fuel, or lower grade fuel. Name brand fuels do add detergents or other additives to their fuel, but generally these additives do not affect the vehicles fuel mileage.

One of the most common reasons for decreased fuel economy is simply that your vehicle is getting older. As your vehicle ages, it starts to lose some of its efficiency. This is due to several factors, including wear and tear on the engine parts and the build-up of deposits in the fuel injectors.

As an engine ages, fuel economy will decrease somewhat. However, in most cases, this decrease in fuel economy has less to do with the age of the engine and more to do with how many miles you've driven and whether your vehicle has faulty or worn engine components.

The most common reason for the fuel gauge to malfunction in a car is due to a bad fuel sending unit. The fuel sending unit measures the amount of gas in the tank and communicates the level to the fuel gauge in your car's dashboard.
