How to calculate car Mileage | Increase car mileage by 30%

Fuel prices are skyrocketing!

Petrol prices are rising daily in today’s world. Who wouldn’t want to save money in such a situation?

Improving your car mileage is the only easy way to save money on gas.

The less fuel your car consumes, the more money you will save.

But before you make any changes you should calculate car mileage.

And then make further decisions that will help you keep track of your car mileage.

Also, many people are concerned that their brand new car is not giving the desired mileage.

It varies from the company’s claimed mileage…

Why is it so?

We have covered that further.

Also, in the end, we have provided 10 expert tips and tricks to improve car mileage. 

So in this blog, we will look at

how to calculate car mileage, 

what are the reasons for the low mileage of your car, and how to improve your mileage by 30%, whether you are using a second-hand car or a new car.

Let’s get started!

How to calculate car mileage

1.To calculate your mileage, fill up your car tank till the auto cut off. Do not exceed the auto cut off-limit 

2. Reset the trip meter reading to zero by pressing and holding the selector knob run your car till the Also Note the  speedometer readings 

3. Then drive your car for approx 150 km, – 150 km is considered as an industry benchmark 

4. As you drive 150 km then again refuel the tank till auto cut off note the fuel consumed

5. Now the final step divides the distance travelled by the amount of fuel consumed.

In Our case, we have suggested driving the distances of 150 km,( please fill your travel distance by looking at the trip meter.) and divide it by the quantity of fuel consumed 


Car mileage = No. of Kms/ Quantity Of Fuel Used

Keep track of every time you fill up your tank. The other option, of course, is to review your monthly fuel bills and compare them to the previous month’s bills. This will assist you in keeping track of your vehicle’s mileage.

What are the reasons for the low mileage of your car

Do you know? 

In the initial days, a brand new car gives low mileage than the company claims.

Also, there is a huge difference in the company claimed mileage versus  practical know milage 

But what’s the reason?

Initially, the car engine is new,  Its parts like Piston, Fuel Lines etc aren’t fully lubricated.

As the time passes- by you drive; engine parts get lubricated and move freely and then you see an increase in your car mileage gradually.

About 800 to 1,000 kilometres are needed for your car to start getting better mileage. This is when the mileage is at its best and will stabilise, and it gets even better when the oil is changed at 7500 – 10,000 Kms.

Now let’s talk about 

What is the reason for low mileage in used cars?

As your car engine gets old it cools and fuel gets clogged up with dirt.

The heats up due to this and burns more fuel than usual.  

It is recommended to clean up the engine filter, change oil & and lubricate the engine parts to maintain the good health of the engine. And make your car fuel-efficient

10+ tips and tricks that can improve your car mileage by 30%

1.Fill up the fuel at night to save some fuel

The outside temperature is very high in the morning and afternoon. Additionally, after a certain distance, your car engine heats up, resulting in fuel evaporation.  While the temperature is low at night, your car remains cool, preventing evaporation and saving fuel.This small change will help you save extra fuel. 

2.Fill the tank only up to auto cut off

Fill the tank up to the point where the auto-shutoff kicks in. Overfilling the fuel tank beyond the automatic cutoff point causes the air chamber to become clogged.

As a result, the car engine will heat up. Finally, the heat will cause the fuel in the tank to evaporate.

3.Avoid sudden braking 

Driving your car at high rpm’s and then suddenly applying brakes. This may be fun for many people but it strongly affects your fuel consumption.

Because when you hit the brakes hard, your car’s transmission automatically or manually shifts down to the lowest gear to regain lost momentum. Fuel consumption increases with lower gears because the engine has to work faster.

4.Replace or clean the Air filter

Our air filters are frequently clogged, and as a result, they do not provide enough cool air to the engine.

To save money on gas, keep your engine cool. Otherwise, a lot of the fuel will evaporate before it can be used.

If your air filters are in good shape, clean them or replace them with new ones.  

5.Relax your left legs Avoid putting them on a clutch plate

Your clutch isn’t a place to put your foot down to rest. Even if you believe no pressure is applied, it most certainly is.

Your foot presses down on the clutch pedal, which causes it to take up the slack. This action has a significant impact on your fuel consumption.

It is recommended that you only use the clutch when needed.

6.Inflate your tyres properly 

It becomes hards for the engine to accelerate your car on an under-inflated tyre

It puts a heavy load on the engine. So to accelerate forward engine consumes more fuel than in a normal condition

It is recommended to install a tyre pressure monitoring system in your car so that if any of the tires has low pressure, the tpms will alert you. 

Also, tpms makes it easy for you to check your tyre pressure.

7.Reduces the weight possible.

The more weight in a car, the more energy is required by the engine.

To meet the energy demand, more fuel is consumed.

Check your boot space; we all tend to stuff things in there that we don’t need. Attempts to lose as much weight as possible

8.keep the speed consistence 

For as long as possible, try to maintain a constant speed. Unnecessary fuel is burned as a result of constant acceleration and deceleration. As a result, maintaining a constant speed allows you to save some fuel.

9.Smooth gear shift…. it’s a car, not a sports car!

Many people tend to swift gear so rapidly as if they are driving a sports car.

The frequent increase and decrease in RPMs consume more fuel.

Drive at a constant speed for best mileage.

At best – if driven at a constant speed of 80 Km/hr in 5th Gear on the highway is for best mileage in a petrol car 

For Diesel Cars – been a higher torque produced at lower rpm – as diesel burns more quickly – the power output on lower speed is better and hence gear change would be much different

Diesel cars also should be driven at 5 gear on a highway at the speed of 80 km/hr

10.Monthly routine check 

A routine check is a healthy practice to keep your car in good condition. 

check your engine oil, clean air filter, check tire tread, measure tyre pressure and fill it if needed. Add coolant, check wheel alignment, etc.
