What is the fuel capacity of a petrol car?
Petrol cars typically hold about 40–60 liters (approximately 10–16 gallons) of fuel in the tank, but the exact capacity depends on the model and market.
The question hinges on how much fuel a car can store, which varies with vehicle size, design priorities, and regional regulations. This article outlines common ranges, explains what drives the differences, and shows how to find the precise capacity for a specific car.
Typical tank sizes by vehicle type
Manufacturers balance range, weight, interior space, and cost when sizing a fuel tank. The ranges below reflect common patterns in contemporary passenger vehicles.
Approximate ranges by category (liters and gallons):
- Subcompact and city cars: about 40–45 L (10–12 gal)
- Compact to mid-size sedans: about 45–60 L (12–16 gal)
- SUVs and crossovers: about 60–70 L (16–19 gal)
- Full-size pickups and large SUVs: about 90–130 L (24–34 gal)
Actual capacity varies by model, trim level, and regional requirements. For precise figures, check the vehicle’s spec sheet or the fuel-filler door label.
How to verify the exact capacity for a specific car
Even within the same category, tank sizes can differ from one model to another. The official capacity is typically published by the manufacturer or listed in the owner’s manual. Some cars also print tank size on the fuel-filler door or inside the glove box.
- Check the owner’s manual or the manufacturer’s official website for the exact capacity.
- Look at the fuel-filler door label, which sometimes includes the tank size and recommended fuel type.
- When refueling, estimate remaining capacity by noting how many liters are added from empty to full; this is an approximate method.
Knowing the exact capacity aids in trip planning, fuel budgeting, and understanding range under different driving conditions.
Summary
Across modern petrol cars, tank sizes generally fall in a broad range from about 40 to 60 liters (10–16 gallons) for standard passenger vehicles, with larger SUVs and trucks often reaching 70–130 liters (19–34 gallons). For a precise figure, always refer to the vehicle’s official specifications.
