While petroleum engines’ thermal efficiency (mechanical output to chemical energy in fuel) has improved since the dawn of the automobile era, it is not the only factor affecting fuel economy. The fuel economy is influenced by the overall design of the vehicle as well as its usage pattern. Because of differences in testing methodologies, published fuel economy varies by jurisdiction.
The Mobil Economy Run, which took place every year from 1936 through 1968 (excluding during World War II), was one of the earliest studies to measure fuel economy in the United States. It was built to deliver accurate fuel economy figures during a coast-to-coast test on real highways, with typical traffic and weather circumstances. The run was sponsored by Mobil Oil Corporation, and it was sanctioned and controlled by the United States Auto Club (USAC). The average fuel efficiency for new passenger cars in the United States improved from 17 mpg (13.8 L/100 km) in 1978 to more than 22 mpg (10.7 L/100 km) in 1982, according to more recent research. In the United States, the average fuel economy for new 2020 model year cars, light trucks, and SUVs was 25.4 miles per gallon (9.3 L/100 km). The US EPA classified 2019 model year cars (including EVs) as “midsize,” with fuel economy ranging from 12 to 56 mpgUS (20 to 4.2 L/100 km). However, in response to environmental concerns raised by CO2 emissions, new EU regulations are being implemented that will reduce average CO2 emissions of cars sold beginning in 2012 to 130 g/km, or 4.5 L/100 km (52 mpgUS, 63 mpgimp) for a diesel-fueled car and 5.0 L/100 km (47 mpgUS, 56 mpgimp) for a gasoline (petrol)-fueled car.
The average fleet consumption is not immediately changed by new vehicle fuel economy: for example, in 2004, Australia’s car fleet average was 11.5 L/100 km (20.5 mpgUS), compared to 9.3 L/100 km for new cars in the same year (25.3 mpgUS)
How can I figure out how much gasoline I’ll need?
If you’re using mpg (miles per gallon), the calculation for figuring out how much gas you’ll need is:
If the distance is 500 miles and the consumption rate is 20 miles per gallon, the total amount of fuel required is 500 / 20 = 25 gallons.
If you’re measuring consumption in gallons per 100 miles, the formula for determining the amount of fuel required is:
If the trip is 300 miles and the consumption rate is 5 gallons per 100 miles, you will require 300 / 100 x 5 = 15 gallons of gas.
Both methods work for metric quantities, such as kilometers and liters; just make sure you don’t mix them up. You may avoid making that mistake by using an online fuel calculator.
How much does a litre of petrol cost in the United Kingdom?
Fuel prices in the UK hit new highs in 2022, with the average price of petrol at 170.62 pence per litre (ppl) and diesel at 181.52 pence per litre (ppl).
Chancellor Rishi Sunak decreased fuel duty by 5p per litre until March 2023 in the Spring Budget, in a bid to match previous record prices of 167.3p for petrol and 179.9p for diesel.
This, combined with lower oil prices, resulted in a decrease in average pump costs in April 2022, however drivers did not benefit fully from the savings.
According to the RAC, the average price of fuel was 162.75p by the end of April 2022, down 0.5p per litre from the beginning of the month. In April 2022, the price of diesel remained unchanged at 177p (it was 177.44p on 1 April 2022 and 177.31p on 30 April 2022).
The average price in April came after three months of fuel prices continuously breaking new records. The highest ever increases in fuel costs occurred in March 2022. According to the RAC, the average price of a litre of unleaded petrol increased by 11.62p to 163.28p at the end of the month, while diesel increased by 22.06p to 177.29p.
The previous highest monthly increase for gasoline was 7.43ppl in October 2021, according to the report. The previous worst month for diesel was May 2008, when the price of a litre increased by 8.43ppl.
On November 22, 2021, the record was 147.72p for petrol and 150.96ppl for diesel. In December, wholesale and retail prices fell, but in January 2022, they began to rise again.

How much does a mile of driving cost?
A mile costs $0.53, according to the Internal Revenue Service. This is the amount you can deduct from your earnings for each mile you drive for work. This is the net cost of driving, expressed as a single number.
I’m not sure how the IRS calculates this figure, but it closely matches the estimate of the Automobile Association of America for the cost of owning a personal automobile.
The AAA calculates it by dividing the annual cost of financing, depreciation, insurance, inspection, registration, taxes, service and maintenance, parking, and tolls by the average miles driven.
These components are shown in the table below, along with how they differ amongst popular vehicle kinds.
How do you figure out the cost of fuel per mile?
Although it is more accurate to calculate gasoline costs when you have a log with fuel and mileage data, you can use estimations if you don’t have access to past data. To calculate yearly fuel cost per mile, divide total real or expected fuel expenses by actual or estimated annual miles driven. For instance, if you drove 15,000 miles last year and spent $1,600 on gas, your fuel cost is 1,600 divided by 15,000, or 10.67 cents per mile.
How much does it cost to drive a car in the United Kingdom per mile?
How much does it cost to drive a car in the United Kingdom per mile? Driving a car now costs roughly 47p per mile, as calculated by dividing average annual auto operating costs of 3,556 by average annual car mileage of 7,600 miles.
What is a good fuel consumption average?
MPG stands for miles per gallon, and it refers to how much gasoline you use in relation to the distance you go. The brand and model of the car, as well as whether it’s new or used, all influence MPG. There are also additional factors to consider, such as the size of the vehicle, the engine, and the driving conditions. The most significant factor, though, is your driving style. Diesel cars are more fuel efficient than gasoline cars on average. Finding a car with a high MPG is usually a good choice because it reduces your running costs and increases your fuel efficiency, especially on longer trips.
The MPG you’ll receive depends on a number of factors. Here are few that have an impact on your MPG:
Regular oil changes, wheel alignments, and progressive acceleration and careful turning are all recommended for getting the most out of your MPG. After all, you’ll get the most out of your car if you take care of it.
Keep in mind that automobile technology is constantly improving, and the inclusion of’stop start’ is an example of how newer models have been optimized for fuel efficiency.
The commonly acknowledged norm has risen from roughly 8.1 to 7.1 litres per 100km (around 60 miles) (35-40mpg) in the past to more like 5.6 to 5.1 litres per 100km (around 60 miles) (35-40mpg) (50-55mpg). Vehicles with an MPG of fewer than 6.0 litres/100km are deemed to have a ‘good’ MPG.
If your MPG does not appear on your dashboard, a smart tip is to drive the car for a decent number of miles (100 is a good number), then fill up whatever you’ve used. Divide the number of miles you drove (in this case, 100) by the amount of gas you used after filling up the tank for the second time. You’d get 50 miles per gallon if you drove 100 miles from a full tank and were able to fill two gallons.
30 MPG is considered good for a used petrol automobile, whereas 60 MPG is usual for a hybrid or electric vehicle.
When looking for a used car with decent MPG, it’s critical to look into the vehicle’s history, as engines that have been well-maintained are more efficient and provide higher fuel efficiency ratings than engines that have been neglected.
These records will show you what has been replaced and how often oil changes have been conducted, as well as the overall condition of the engine and vehicle. The MPG of a vehicle with a lot of miles on it but has been properly maintained is unlikely to be affected by the amount of miles on the vehicle.
It’s also recommended to choose a tiny city automobile, even if it doesn’t have much power or isn’t ideal for long distance trips. It’s also a good idea to buy a car with a license plate no older than 2014 because you can almost guarantee that the car and engine are still in good condition, and the car may even have some of the same fuel-saving features as a new vehicle. You want something that is efficient, affordable, and has low operating costs, as this will save you a lot of money in the long run on fuel and maintenance.
A good MPG for a new automobile is roughly 50 to 60. This enhanced fuel economy contributes to lower operating expenses and lower road tax due to lower CO2 emissions.
Here are five of the most fuel-efficient automobiles on the market today, according to What Car’s featured blog.
Overall, having a decent mpg car depends on the type of car you want, the type of driving you’ll be performing, and the location you’ll be driving. You probably don’t care about the mileage if it’s a weekend car, but if you’re planning to use it on a daily commute, you’ll want greater mpg.

Is 10 kilometers per litre a good number?
litres per 100km (litres/100km) is the first (and most popular) reference. This is the amount of fuel required for an automobile to travel 100 kilometers. It’s commonly referred to as ‘fuel economy.’ On this one, the lesser the indicated number of litres, the higher the fuel economy.
Kilometers per litre (km/1-litre) is another technique to look at a car’s fuel consumption that isn’t as popular in Australia. The larger the number of kilometers traveled, the more fuel-efficient the vehicle.
In Australia, petrol is the most extensively utilized fuel, but diesel is gaining popularity. Diesel sales have nearly doubled in the last decade, and the notion that diesel is only for filthy, stinky vehicles is long gone.
Diesel engines are, on average, more fuel efficient than gasoline engines. Instead of spark plugs, they use compression ignition, which results in a more efficient fuel burn. This necessitates a more advanced engine design, which is one of the reasons diesel cars are more expensive than gasoline cars.
Modern turbocharged diesel engines offer a lot of pulling power and are commonly turbocharged (also known as torque). It can shift gears faster than a gasoline engine and runs at lower revs per minute. As a result, it consumes less gasoline at each stage than a comparable petrol engine.
