Knowing How to Calculate Average of Car will help you figure out why your car seems to gulp fuel way too fast or just wanted to know if your car provides good value or not. You don\u2019t need a special divide or tool to calculate that, just follow easy steps with patience to find the exact car average.\u00a0<\/span><\/p>\n

What Does “Car Average” Actually Mean?<\/span><\/h2>\n

Car Average means fuel efficiency, how many kilometres your car travels on 1 litre of petrol or diesel. So, here is an example, if your car gives 15 km\/l, it means 1 litre of fuel lets you drive 15 kilometres.\u00a0<\/span><\/p>\n

If the number is getting higher then your car is giving you great mileage and saving your money on fuel. Every car brand shows an “official” mileage figure but real-world average can be different because of your driving style and road conditions. That\u2019s why calculating the average of a car by yourself is a good idea.<\/span><\/p>\n

Mileage (km\/l) =<\/b> Distance Travelled \u00f7 Fuel Used<\/span><\/p>\n

Example:<\/strong> You drove 450 km and used 9 litres \u2192 Average = 450 \u00f7 9 = 50 km\/l<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Tank-to-Tank Method\u00a0<\/span><\/h2>\n

1.Fill Your Tank Completely<\/b><\/h4>\n

Fill the tank to the top when you go to the petrol pump. Don\u2019t let them stop filling until the nozzle clicks and stops automatically.\u00a0<\/span><\/p>\n

2.Note Your Odometer Reading<\/b><\/h4>\n

Check your dashboard, it shows the total distance, write it down somewhere. For example: 12,500 km.<\/span><\/p>\n

3.Drive Normally<\/b><\/h4>\n

Use your car as you did before whether city driving, highway, office trips. Let the fuel drop to lower before you return to the pump.<\/span><\/p>\n

4.Fill Up Again Completely<\/b><\/h4>\n

Again fill the tank to the top with fuel at the petrol pump and note exactly how many litres were put in. For example: 9.5 litres.<\/span><\/p>\n

5.Note the New Odometer Reading<\/b><\/h4>\n

Check the total distance on the dashboard (odometer) again. If it shows 12,950 km. subtract the first reading to the current reading and you get the travel distance to put into the formula.<\/span><\/p>\n

6.Apply the Formula<\/b><\/h4>\n

Mileage = 450 km \u00f7 9.5 litres = <\/span>47.4 km\/l<\/b> \u2014 that’s your real-world car average!<\/span><\/p>\n

Other Ways to Calculate Car Average<\/span><\/h2>\n

Trip Meter Method<\/span><\/h3>\n

Reset the trip meter to zero after a full tank fill. After refueling next time, divide the trip meter reading by litres added. Same formula, less maths.<\/span><\/p>\n

Mileage Tracking Apps<\/span><\/h3>\n

Apps like <\/span>Fuelio, Drivvo,<\/b> and Road Trip track every fill-up and calculate your rolling average automatically over weeks and months.<\/span><\/p>\n

Car’s MID Display<\/span><\/h3>\n

Maruti, Hyundai, Tata cars have a Multi-Information Display (MID) that shows mileage of the car. But it’s not an exact average number.\u00a0<\/span><\/p>\n

Pro tip: For finding the most reliable results of the car’s average, calculate over 2-3 full tanks. A single tank result can give you wrong numbers because of unusual driving. One long highway trip or a week of only short city rides will give you totally different numbers.<\/span><\/p>\n

What Affects Your Car’s Average?<\/span><\/h2>\n

You might calculate 17 km\/l one month and only 12 km\/l the next \u2014 without changing anything obvious. Here are the main factors that affect how to calculate average of car in real conditions:<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n
Factor<\/b><\/td>\nWhat Happens<\/b><\/td>\nImpact<\/b><\/td>\n<\/tr>\n
City vs Highway<\/span><\/td>\nStop-and-go city traffic burns more fuel than smooth highway driving<\/span><\/td>\nHigh<\/span><\/td>\n<\/tr>\n
AC Usage<\/span><\/td>\nRunning AC constantly can reduce mileage by 10\u201320%<\/span><\/td>\nHigh<\/span><\/td>\n<\/tr>\n
Tyre Pressure<\/span><\/td>\nUnder-inflated tyres burn more fuel to move forward while creating high resistance.<\/span><\/td>\nMedium<\/span><\/td>\n<\/tr>\n
Driving Speed<\/span><\/td>\nBest efficiency is usually between 60\u2009\u2063\u2212\u2009\u206380 km\/h. It drops the mileage point after surpassing the 100 km\/h.<\/span><\/td>\nHigh<\/span><\/td>\n<\/tr>\n
Engine Health<\/span><\/td>\nDirty air filter, old spark plugs, or low engine oil all reduce mileage<\/span><\/td>\nMedium<\/span><\/td>\n<\/tr>\n
Car Load<\/span><\/td>\nMore passengers or heavy luggage means the engine works harder<\/span><\/td>\nLow\u2013Mid<\/span><\/td>\n<\/tr>\n
