How Far on a 35-Liter Tank? Fuel Range Calculator

Fill the tank, reset the trip meter, read the number

Every driver has done the mental math: tank says half full, consumption is around 7 liters, how far can I actually go? This calculator gives you that answer without guesswork. Enter the tank size in liters and the average fuel consumption in L/100km - the result shows the full-tank range in kilometers and miles, plus the same figure for a half tank and a quarter tank. You also get a vehicle classification so you can quickly sense-check whether the numbers look right for your type of car.

The formula is straightforward: divide tank capacity by consumption rate, multiply by 100. A 60-liter tank with 8 L/100km gives 750 km. Real-world range is always a bit less because you rarely start from a truly full tank and you should not run to empty - the calculator shows theoretical maximum range, which is the right starting point for trip planning.

How to use the calculator

1
Enter tank capacity (liters) - find this in your owner manual, on the fuel filler cap, or look it up by model. Compact cars: 40-55 L. SUVs: 60-80 L. Trucks: 100-300 L. Motorcycles: 12-20 L.
2
Enter average fuel consumption (L/100km) - read it from the trip computer (long-term average, not instant). If you do not have a trip computer, divide liters added at the last fill-up by the distance driven since the previous fill-up, then multiply by 100.
3
Read the results - the calculator returns range at full tank, half tank and quarter tank, both in km and miles. It also shows the vehicle type and fuel consumption category so you can verify the inputs are realistic.

Vehicle type comparison - tank, consumption and range

The table below covers eight common vehicle categories with typical tank sizes, average consumption and the resulting full-tank range.

Vehicle type	Tank (L)	Consumption (L/100km)	Full-tank range (km)
Compact petrol (e.g. VW Golf, Toyota Corolla)	50	6.5	769
Compact diesel (e.g. VW Golf TDI, BMW 316d)	50	4.8	1,042
Family sedan petrol (e.g. Toyota Camry, Skoda Octavia)	60	7.5	800
Mid-size SUV petrol (e.g. Toyota RAV4, VW Tiguan)	60	9.0	667
Full hybrid (e.g. Toyota Prius, Hyundai Ioniq)	43	4.0	1,075
Large SUV diesel (e.g. BMW X5, Mercedes GLE)	80	7.5	1,067
Motorcycle (e.g. Honda CB500, Kawasaki Z650)	17	4.5	378
Sports car (e.g. Porsche 911, BMW M3)	64	13.0	492

Common mistakes when estimating range

Mistake 1 - Ignoring the reserve: The fuel gauge hits empty at about 5-10% of tank capacity, not at zero. A 60L tank that shows empty still has 3-6 liters left. But driving on reserve stresses the fuel pump and can leave sediment in the system. Always plan to refuel before the gauge hits the red zone.

Mistake 2 - Ignoring the winter penalty: Cold weather reduces range by 10-20% in petrol/diesel cars and up to 40% in hybrids and PHEVs. Engine warm-up burns extra fuel, heating the cabin draws power, and cold tyres have higher rolling resistance. If your summer consumption is 7 L/100km, budget 8-8.5 L/100km in January.

Mistake 3 - Using city consumption for a highway trip (or vice versa): Stop-and-go city traffic burns 20-40% more fuel than steady motorway cruising for petrol engines. Diesel engines handle city driving better but still see a penalty. If you know you will be doing mostly highway, use a lower consumption figure; for city driving, use a higher one.

Mistake 4 - Forgetting AC and heating load: Running the air conditioning adds 0.5-1.5 L/100km to consumption depending on outside temperature and AC intensity. Seat heating adds a smaller amount. On a 700 km road trip in summer with AC on, you might burn 5-8 liters more than the calculator suggests based on winter trip data.

Practical examples

Example 1 - Warsaw to Krakow (295 km): VW Golf petrol, 50L tank, consumption 7 L/100km. Full-tank range: 714 km. The trip is 295 km, so you can make it there and almost back before needing fuel. One fill-up covers the round trip.

Example 2 - London to Edinburgh (663 km by road): Toyota Prius hybrid, 43L tank, consumption 4.5 L/100km. Full-tank range: 956 km. The Prius makes it non-stop with range to spare - no fuel stop needed on the motorway.

Example 3 - Motorcycle weekend trip (400 km): Honda CB500, 17.5L tank, consumption 4.2 L/100km. Full-tank range: 417 km. Just barely enough for 400 km, but only if you start full and conditions are perfect. Refuel at the 200 km mark to be safe.

Example 4 - SUV towing a trailer: BMW X5 diesel, 80L tank, normal consumption 7.5 L/100km, towing consumption 11 L/100km. Normal range: 1,067 km. Towing range: 727 km. A 340 km reduction - factor this in when planning stops on a caravan holiday.

Example 5 - City delivery van: Ford Transit diesel, 70L tank, city consumption 12 L/100km. Full-tank range: 583 km. With multiple stops and idling, real range is closer to 500-550 km. Budget for a daily fill-up on busy delivery routes.

Example 6 - Hybrid in winter: Toyota RAV4 Hybrid, 55L tank, summer consumption 5.5 L/100km, winter consumption 7.5 L/100km. Summer range: 1,000 km. Winter range: 733 km. Plan an extra fuel stop on winter road trips compared to summer.

FAQ - Frequently asked questions

How accurate is this range calculator?

The calculator gives the theoretical maximum range based on the numbers you enter. Real-world range is typically 5-15% lower because: you rarely start with a perfectly full tank, you should not drive to empty, driving conditions (hills, wind, traffic) vary, and AC or heating adds consumption. Use the result as an upper bound and plan conservatively - especially for remote routes with few fuel stations.

Where do I find my tank capacity?

Three reliable sources: (1) the owner manual - look in the specifications section, usually listed as "fuel tank capacity"; (2) the fuel filler cap or door - some cars stamp the capacity there; (3) the manufacturer website or a marque-specific forum. If you know the exact model and year, a quick web search for "[model] fuel tank capacity" is usually faster than digging out the manual.

How do I calculate my actual fuel consumption?

Fill the tank to the brim and reset the trip meter. Drive normally. At the next fill-up, note how many liters you added (that is what you consumed) and check the trip meter distance. Formula: consumption = (liters added / km driven) x 100. Example: added 42 liters after 560 km = (42/560) x 100 = 7.5 L/100km. Repeat over 3-4 fill-ups and average the results for a reliable figure.

Does speed affect range significantly?

Yes. Aerodynamic drag increases with the square of speed, so fuel consumption rises sharply above 100 km/h. A car doing 120 km/h uses roughly 20-25% more fuel than the same car at 90 km/h. Going from 90 km/h to 130 km/h can cut range by 30%. On a 600 km motorway trip, driving at 110 km/h instead of 130 km/h can save 5-8 liters of fuel and extend range by 60-80 km.

How do I convert MPG to L/100km?

Use the formula: L/100km = 235.21 / MPG (UK gallons) or L/100km = 282.48 / MPG (US gallons). Examples: 40 MPG (UK) = 235.21 / 40 = 5.9 L/100km. 30 MPG (US) = 282.48 / 30 = 9.4 L/100km. UK and US gallons differ (1 UK gallon = 4.546 L, 1 US gallon = 3.785 L), so always check which MPG figure you are working with.

Why does the fuel gauge not show how much fuel is left accurately?

Fuel gauges use a float sensor in the tank that is not perfectly linear. Most manufacturers intentionally calibrate the gauge to drop slowly at the full end (so the tank "feels full" longer) and drop faster near empty (to warn you earlier). This means half on the gauge is rarely exactly half in the tank. The "empty" warning light typically comes on with 5-10% of capacity remaining - usually 3-6 liters for a 50-60L tank. Never rely on the gauge alone for precise range planning.
