Driving in the highest gear possible without labouring the engine is a fuel-efficient way of driving. Driving at 60 km/h, a vehicle will use 25 per cent more fuel in third gear than it would in fifth. Travelling at fast rates in low gears can consume up to 45 per cent more fuel than is needed.
Which gear uses the most fuel?
3 – Use the highest possible gear
All cars are designed to start at the lowest gear, as that’s where you get the most power for acceleration, but driving at the highest gear will increase fuel economy. Fuel consumption will increase when you stay long at lower gears.
Which gears save fuel?
Virtually all manual and automatic transmissions have an overdrive gear that can be employed to save fuel. It’s usually the highest-numbered gear (or gears), and it lets the engine run at a slower speed (or lower rpm) while the car maintains the same road speed.
What is the best speed to save fuel?
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).
Why are higher gears more fuel efficient?
Almost always, a higher gear is more efficient on flat ground because you need almost no load on the engine. On a hill where you demand increased power, it may be more efficient to shift toward your torque peak, especially if you’re putting more than 50% load on the engine.
Does 5th gear save petrol?
Using your gears properly can also help reduce fuel consumption. Make sure you use higher gears at lower speeds such as 4th gear at 30mph, 5th gear at 40mph and so forth.
What gears for what speed km?

Does manual mode save gas?
In our tests, we’ve found that in some cars a manual transmission can improve gas mileage by a significant 2 to 5 mpg, compared with an automatic, and can cut a car’s price by $800 to $1,200. Manual transmissions often can also improve acceleration, sometimes significantly.
Can I drive in 4th gear?
Page 82 states that “Driving excessively in 4th gear will lead to a known but unpreventable condition called SMEF or Spontaneous Massive Existance Failure whereas your car will be taken from you and given to someone who knows how to drive stick.” Just messin’ with ya, you’re fine.
Does skipping gears save fuel?
Why does skipping gears increase fuel economy? It’s pretty simple; when you skip gears effectively and upshift, you’ll achieve an increase in speed. What that means is that you’ll be able to reduce the amount of time it takes to accelerate – this is an efficient driving technique for saving fuel consumption.
Does holding clutch save fuel?
No, it’s called coasting. You can do it by disengaging the clutch or putting it into neutral, which saves your clutch hand. It won’t damage your engine and will technically save fuel.
Does driving slow save petrol?
Drive smoothly
Aggressive driving such as rapid acceleration, speeding and braking can lower your fuel mileage significantly. So, accelerate smoothly, brake softer and earlier, and stay in one lane while it’s safe to do so.
Does fast driving waste fuel?
Speeding increases fuel consumption and decreases fuel economy as a result of tire rolling resistance and air resistance. While vehicles reach optimal fuel economy at different speeds, gas mileage usually decreases rapidly at speeds above 50 miles per hour (mph).
How can I reduce fuel consumption?
10 ways to reduce fuel consumption
- Keep tires pumped up. Tires that are underinflated have a higher rolling resistance on the road.
- Lose the weight in your boot.
- Drive with AC.
- Don’t go too fast or too slow.
- Remain steady when accelerating.
- Avoid braking aggressively.
- Cruise in top gear.
- Practice predictive driving.
Does more gears mean more speed?
A higher gear increases the speed of the wheel but decreases the torque (force) that the wheel produces (for a given engine speed). The faster the car goes, the faster the wheels need to spin but also the more force it needs to overcome air resistance.
How do I get fuel-efficient?
Fuel-efficient driving techniques
- Accelerate gently. The harder you accelerate the more fuel you use.
- Maintain a steady speed. When your speed dips and bursts, you use more fuel, and spend more money, than you need to.
- Anticipate traffic.
- Avoid high speeds.
- Coast to decelerate.
- More ways to use less fuel.
- Challenge yourself.
Does driving in a higher gears save petrol?
The faster an engine spins, the more fuel it uses, so allowing your car to reach excessively high revs in any gear is not good for fuel efficiency. It’s actually more economical to drive in a higher gear.
Is fuel saver for real?
It may sound silly, but they actually work. Yes, you can install a device into your vehicle to save money. Effuel seems to function like other performance chips, tracking driving habits and saving you money in gas. Most performance chips target the power of your engine, changing the way your engine uses power.
What is fuel shark?
Fuelshark claims to save you ten percent or more on gas, by simply plugging the $39.95 device into your cigarette lighter. The strange alienesque device glows blue, and according to the company, uses a capacitor to “stabilize your car’s electrical system”.
What is 5th gear used for?
The fifth gear is recommended for use in maintaining highway cruising speeds. Use of the fifth gear in city traffic is not recommended. The shift speed chart shows the speeds at which each upshift of the transmission should be made to get the best vehicle performance and fuel economy.
What is 2nd gear used for?
Second gear works just like the first gear, except you should only enter second gear once you’re done with the first. Good scenarios for second gear are when you’re on a slippery road and need to lower your speed for your tyres to get a better grip on the surface. You can also use 2 for engine braking downhill.
