Does driving slower save fuel?

Does driving slower save fuel?

The short answer: Nope. The reason: The common understanding is that going faster burns more fuel and therefore, the slower you drive, the less fuel your car will use, but this actually isn't true. … Any slower, and your transmission will automatically shift to a lower gear, which requires more fuel to maintain.

What speed is most fuel efficient?

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.

How can I get better mpg when driving?

“We found that limiting your maximum speed to 60 MPH reduces your fuel consumption by 10%,” said Simon East, CEO of DriveGain, “but that this only adds 2 minutes to the average journey time”.

Does driving in a higher gears save fuel?

If you accelerate gradually to a suitable cruising speed, it might not be necessary to change up by one gear and then into the next, and the next- you can simply skip a gear instead. Driving in a higher gear than necessary can also improve fuel economy, as long as the engine isn't struggling.

What is a good fuel consumption per 100km?

Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km.

Does cruise control use more gas?

RAY: Using cruise control on the highway does save fuel, for exactly the reason you say: It keeps you moving at a very steady speed. Continuing to move at a steady speed uses less fuel than accelerating. TOM: When you drive without cruise control, you tend to slow down, speed up, slow down, speed up, etc.

What is the best rpm for fuel economy?

It is likely to be geared for 2500 rpm or so at that speed, yet for maximum efficiency the engine should be running at about 1000 rpm to generate that power as efficiently as possible for that engine (although the actual figures will vary by engine and vehicle).
