For instance, if your vehicle gets 30 mpg, it travels 30 miles per one gallon of gas. The mpg is usually higher on highways compared to city driving since city driving necessitates slower speeds, idling, and higher revolutions per minute rpm.
According to Autolist, most vehicles achieve at least five more mpg on the highway than in the city. You can also measure gas mileage in terms of gpm, which is the number of gallons needed to move a vehicle miles. The gpm helps determine the vehicle's fuel economy when taking other considerations into account. A hybrid is another fuel-efficient vehicle to consider. This option uses a gas and electric engine to operate. Its electric motor usually operates the vehicle slower speeds or when idling before it kicks over to the gasoline engine.
Hybrids can operate more efficiently and cleaner compared to gasoline-powered engines. Although they began as smaller cars, hybrids are available in larger vehicles and SUVs. Per Green Car Reports , the vehicle's history also affects fuel economy. A newer or well-maintained vehicle typically attains better gas mileage compared to one with numerous miles or in poor drivable condition. Change the oil and its filter regularly and keep the tires properly inflated to get better gas mileage.
Although it's tempting to look at a vehicle that gets 50 mpg on the highway and say it's fuel-efficient, you might not drive that same vehicle.
Examine the fuel economy rating for each specific type of vehicle to compare. For instance, with the Porsche Boxster, you get 25 mpg combined, while the Honda Accord LX achieves 31 mpg combined. You might think the Accord gets the better fuel economy; however, the 25 mpg combined with a sports car is a solid number. The EPA says these fuel-efficient passenger vehicles are the leaders in each class.
They're listed with mileage combined. Since a majority of those previous vehicles listed are electric, take a look at the best fuel-efficient gasoline-powered or hybrid vehicles. If your car has a trip odometer, reset it, or record the master odometer mileage. Drive your car as you normally would, and let your gas tank deplete to at least a half of a tank of gas. Get to the gas station and fill your tank again. Record the amount of gas it took to refill the tank.
Record the elapsed trip miles or new odometer mileage. Calculate Get the miles traveled from the trip odometer, or subtract the original odometer reading from the new one. Divide the miles traveled by the amount of gallons it took to refill the tank. Responses 0 How to Calculate Gas Mileage - 0. From Our Shop. Farmstead Raised Garden Bed.

Low-pressure tires are a common cause of worsening MPG because an underinflated tire has increased rolling resistance with the road and a slightly smaller effective diameter.
Modern cars come with a tire pressure monitoring system TPMS to notify drivers when their tires need more pressure, but the warning is only triggered after a significant loss of PSI. One of the easiest things you can do to keep up fuel efficiency is to regularly check your tire pressure and top-up with air as needed. Another smart option is to use Bridgestone Ecopia tires , which are made with fuel economy in mind. Ecopia tires feature a low rolling resistance tread designed to help you save both money and fuel with fewer trips to the gas pump.
Not only is it dangerous to drive with worn-out brake parts , but sticky brakes could also be causing your MPG to plummet. Brake drag means your engine must constantly fight with the brakes just to move, causing fuel efficiency to drop dramatically.
Be sure to check your brakes regularly — or simply bring your car into Firestone for a comprehensive brake inspection. Just like with low-pressure tires, misaligned wheels create resistance to traveling straight down the road. Constantly fighting this resistance requires more effort from the engine and hurts fuel economy.
Luckily, wheel realignment is a simple fix that can be done at any Firestone Complete Auto Care location near you.

Blog Categories Blog Home. Clogged or Damaged Fuel Injectors One of the most common culprits for a drop in fuel efficiency is dirty fuel injectors.
Old Engine Air Filter Engines must suck in air to power vehicles. Dirty Oxygen Sensor Whereas many older cars use carburetors to ensure the engine receives the proper ratio of air-to-fuel for combustion, all newer cars since about use oxygen sensors instead.
Clogged Fuel Filter Fuel filters block contaminants in the fuel from traveling throughout the engine where they could damage fuel injectors and other important parts. Worn Out Piston Rings The piston rings in your engine cylinders form a seal against the cylinder walls to create compression. Bad Ignition System Parts The ignition system includes coils, spark plugs, and wires that are responsible for combusting the air-fuel mixture in the engine.
