Understanding fuel consumption ratings
Fuel consumption ratings give consumers reliable information about the relative fuel efficiency of vehicles. You can use this information to compare the fuel consumption of different models and then choose the most fuel-efficient vehicle that meets your everyday needs.
Use the fuel consumption ratings search tool to compare the fuel consumption information of different models. The vehicle with the best fuel consumption ratings and lowest estimated annual fuel cost can save you fuel and money for years.
You can also use the annual Fuel Consumption Guide, which is put together by Natural Resources Canada with the help of Environment and Climate Change Canada. The guide gives model-specific fuel consumption information about light-duty vehicles.
Remember, the lower the litres per 100 kilometres (L/100 km) rating, the better the fuel consumption. And the higher the miles per gallon (mpg) rating, the better the fuel use.
Your fuel consumption will vary
Fuel consumption ratings show the fuel consumption that may be achieved if you drive in fuel-efficient ways and properly maintain your vehicle. The ratings help you compare the fuel consumption of different vehicles. However, it is impossible for a laboratory test to simulate all conditions that drivers may experience. Your vehicle’s fuel consumption will vary from its published fuel consumption ratings, depending on how, where and when you drive.
The following factors will affect the fuel consumption of your vehicle:
- How you accelerate
- How fast you drive
- The age and condition of your vehicle
- Temperature and weather
- Traffic and road conditions
- Using air conditioning and other powered accessories
- Using all-wheel and four-wheel drive
Also, there may be fuel consumption differences in the same make and model because of small variations in vehicle manufacturing. And some vehicles do not get their best fuel consumption until they have been driven for about 6,000 to 10,000 km.
Published ratings are a useful tool for comparing vehicles before you buy. But keep in mind that they’re based on standard tests and may not accurately predict the fuel consumption you will get on the road.
Use fuel-efficient driving techniques to reduce your vehicle’s fuel consumption and carbon dioxide emissions by as much as 25%.
