Read a fuel rating without guessing.

Start with the unit

Natural Resources Canada’s comparison tool presents vehicle fuel-consumption information and lets readers personalise distance and energy-price assumptions. For L/100 km, a lower number means less fuel used over the same distance. Use the exact model and configuration when consulting official ratings.

Work one example by hand

Suppose a vehicle uses 8 L/100 km and travels 12,000 km. The arithmetic is 12,000 ÷ 100 × 8 = 960 litres. At an illustrative CAD $1.70 per litre, the fuel-only total is CAD $1,632. These are chosen example inputs, not current fuel prices or a claim about a particular car.

Compare like with like

Do not compare one person’s city record with another vehicle’s highway rating as though they described the same journey. Keep the source, unit and use case beside each number. When a number is missing, leave the field open rather than borrowing a favourable value from another model.

Keep the result in its lane

An energy calculation is not the cost of owning a vehicle. It excludes purchase price, financing, insurance, maintenance, registration and resale. Our calculator intentionally isolates energy so its assumptions remain visible.
