Looking to reduce your fuel costs and get the most out of each tank of gas? Knowing your car’s fuel consumption is a great way to do this.

Our first suggestion is to read the fuel consumption ratings published by Natural Resources Canada. They are a useful tool for comparing vehicles before you buy, but remember that they are based on standardized tests. If you want to know the precise fuel consumption of your vehicle throughout the year, you’ll need to know how to measure it.

Use your car’s on-board computer to calculate your fuel consumption

You’ve noticed that modern cars have a digital dashboard that tracks fuel consumption. Depending on the model, it can provide information such as average fuel consumption since new, last fill-up, start-up or last reset. Some of the more advanced models even offer real-time tracking to show how sudden acceleration or climbing a hill affects your fuel economy.

How accurate are these gauges? Automotive technology has advanced considerably in recent years, allowing you to get a quick and reliable estimate. However, it is also possible to calculate your consumption manually by following a few steps.

Calculate your consumption yourself

When you manually measure your car’s fuel consumption, focus on the figure in liters per 100 kilometers (L/100 km). To get an accurate estimate, fill up your tank and record how many kilometers you’ve driven before refueling at the next station. You can also reset your trip meter and drive until you reach a gas station to refuel. In any case, remember that accuracy is crucial in calculating the amount of fuel your vehicle uses.

This is where the math starts! First, note the amount of fuel you just put in your tank. Then, do the same with the distance you’ve driven since you last filled up. Now you can use a simple calculation to determine your fuel consumption.

Here’s an example: To fill up your tank, you needed 34.75 liters after driving 395.6 kilometers. Using the rule of three, the fuel consumption is calculated by multiplying 34.75 liters by 100 divided by 395.6 kilometers, which gives you a consumption of 8.78 L/100 km.

Do this calculation several times and compare the results with your trip computer reading to make sure they match. If it does, you can trust it!

In conclusion, there are many reasons why it may be important to monitor your fuel consumption:

  • It can help you assess the cost of operating your vehicle and plan your fuel expenses.
  • It can help you identify and resolve vehicle performance problems.
  • It can help reduce your carbon footprint by allowing you to reduce your fuel consumption.
  • It can help improve your driving efficiency by showing you how to drive more fuel efficiently.
