Calculate fuel mileage by dividing the amount of miles traveled by the gallons used. Make sure you reset your odometer after refilling your tank. On your next refueling, note the gallons used.Know More
The most accurate way to determine gas mileage is to run your vehicle until it is completely out of gas. Doing this requires using a 1-gallon gas tank to refuel your vehicle just enough to get to a gas station.
By completely running your vehicle out of fuel and using a 1-gallon can to get you to a gas station, you have a very accurate way to measure your mileage. If your tank holds 16.9 gallons and you fill it with 16.7 gallons, you know that you have 16.9 gallons in your tank because the missing .2 gallons is from the one-gallon gas can. Make sure to reset the travel odometer after filling the tank.
Once your vehicle is completely out of gas again, simply look at your miles traveled, and divided it by your tank size (miles travel ÷ tank size = mileage).
Depending on the type of car, idling consumes between 0.08 and 0.13 gallons of fuel every 10 minutes. Turning off a car's engine when parked for more than 10 seconds can improve fuel economy.Full Answer >
Using the air conditioner instead of rolling down the windows improves fuel efficiency at higher speeds, primarily over 65 miles per hour, but decreases fuel savings at speeds under 65 miles per hour. Driving with the windows down makes cars fuel efficient in urban settings, such as city driving. However, many other factors, such as vehicle type and outside temperature, also affect fuel economy.Full Answer >
A vehicle should have a fuel system cleaning every 60,000 miles. However, this depends a lot on what type of car it is, and what the manufacturer recommends.Full Answer >
The amount of fuel needed for a road trip is roughly calculated by dividing the total amount of miles to be traveled by the vehicle's miles-per-gallon (MPG) rating. The amount of miles required is found by using services such as Google Maps or MapQuest, while a vehicle's MPG rating is listed in the owner's manual or can be directly calculated.Full Answer >
