How do you read fuel economy MPG?
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. The result will be your car’s average miles per gallon yield for that driving period.
Is MPG gauge accurate?
As gas prices rise, drivers are paying closer attention to the fuel economy gauges that are found in most late-model cars as part of the trip computer. The only problem is that the gauges are inaccurate. In fact, Edmunds testing reveals that one such gauge claimed fuel economy 19 percent higher than the actual result.
What is good MPG for fuel economy?
The generally accepted standard has risen from a consumption of around 8.1 to 7.1 litres per 100km (35-40mpg) in the past to more like 5.6 to 5.1 litres (50-55mpg). As a rule of thumb, vehicles listed at less than 6.0 litres/100km are considered to have ‘good’ MPG.
How can I improve my MPG?
Fuel Economy Tips: How to Get More MPG
- 10 BEST FUEL ECONOMY TIPS.
- 1 – DRIVE STEADILY. Engines burn more fuel by accelerating and decelerating than by travelling at a constant speed.
- 2 – AVOID HEAVY BRAKING.
- 3 – STOP OVER-REVVING.
- 4 – CHECK YOUR TYRES.
- 5 – SLOW DOWN.
- 6 – TURN OFF THE ELECTRICS.
- 7 – DON’T COAST.
How far can I go on a full tank of gas calculator?
To calculate your car’s total range, multiply its average highway miles per gallon by its fuel capacity. For example, if your car averages 25 miles per gallon on the highway and has a 12-gallon fuel tank, its range is 25 x 12 = 300 miles.
How does the MPG readout on my car work?
That display shows the average fuel consumption over a given period of time. With that type of device you can see how much fuel, on average, your morning commute uses or how many miles per gallon you got on your last road trip.
How does the fuel economy gauge work on a car?
Roger Clark, senior manager of GM’s energy center, explains that the fuel economy gauge makes a calculation by counting the number and duration of pulses made by the fuel injectors as they squirt gasoline into the combustion chambers of the engine. The onboard computer system divides the distance the car travels by this estimated fuel consumption.
What does the Edmunds fuel economy gauge show?
In the Edmunds test, the fuel economy meter was compared to the actual gas mileage the car delivered. Fuel economy gauges, which show both average and current fuel economy, are standard equipment in 92 percent of 2011 vehicles, according to Edmunds data.
How are MPG ratings different from average fuel consumption?
There’s an important distinction to make here. EPA fuel economy ratings are only an estimation of average fuel consumption for a given type of driving, and many cars come with an average fuel consumption display. That display shows the average fuel consumption over a given period of time.
