Dirty or Worn Spark Plugs Dirty or worn out spark plugs affect the way your engine burns fuel in the combustion chamber. Worn out spark plugs causes gas to be left unburned, wasting it. In turn, this waste means your getting fewer miles per gallon.
Creating a 100 mpg car is actually quite easy. Engineers have designed vehicles that were capable of several times that amount. The problem is that those vehicles could barely qualify as ” cars ,” much less a vehicle that can take a family of four to the movies.
2021 Most and Least Efficient Cars
|Most Efficient Cars by EPA Size Class (excluding electric vehicles)|
|EPA Class||Vehicle||Combined MPG|
|Midsize||Toyota Prius Eco 1.8 L, 4 cyl, Automatic (variable gear ratios) Hybrid||56|
|Large||Hyundai Ioniq Blue 1.6 L, 4 cyl, Automatic (AM-S6) Hybrid||59|
Much depends on the type of vehicle you prefer, but if any car gets 35 mpg , then you might consider that good . Others are satisfied with 30 mpg , but if you have a large SUV or pickup truck, getting 20 mpg is outstanding.
The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).
Going slower technically saves fuel because at high speed your engine needs to work harder to overcome drag from wind resistance, your tyres and transmission, and that drag increases exponentially the faster you go. Reduce your speed, then less power (and thus fuel ) needs to be expended to overcome that drag.

The Toyota Prius is especially known for its fuel efficiency, achieving up to an estimated 50 mpg on some models. Now, Toyota has come out with the 2020 Toyota Corolla . This new Toyota car offers hybrid and non-hybrid engine options that boast a fuel economy good enough to rival the Toyota Prius .
A normal petrol engine just has trusty old gasoline and no fancy electric motors. While the Prius gets around 60 mpg , something that gets at least 30 mpg might classify as good . Here are some cars that get at least 30 mpg from the last few years: 2014 BMW 328i (35 mpg highway, $21,000)

But with all that being said, a good MPG figure to aim for is anything between 50 and 60MPG. This will ensure that your car is efficient and economical, which means low running costs and car tax rates.
Getting 15 MPG driving around town might be entirely acceptable for some people as good fuel economy . For others, this might be low. For example, a 2019 Porsche Boxster gets 25 MPG combined city and highway, while a 2019 Honda Accord LX gets 31 MPG combined. But 24 MPG combined for a sports car is not bad.
20 Simple Tricks For Better Gas Mileage Ditch the MPG ratings. Lay off the damn loud pedal. And the brake. Don’t speed. Get the junk out of your trunk. Don’t fill up your tank. Turn off your A/C. Idling in traffic.
