Truck Mileage Per Litre in India: Claimed vs Real kmpl, and How to Measure Yours

Every brochure shows a mileage number. Few working trucks match it exactly. Read the claim as a stated range for a new truck, then measure the truck you are actually running.

Stated Ranges for the 16-Ton Class

A 2026 comparison of new 16-ton trucks lists stated ranges such as about 8 to 10 km/L for a Tata LPT 1618, about 9 to 11 km/L for an Ashok Leyland Ecomet 1615 HE, about 9 to 11 km/L for a BharatBenz 1617R, and about 10 to 12 km/L for an Eicher Pro 2116XP. The same comparison uses 10 km/L as an average in its fuel-cost examples. These are stated figures for new models, not a guarantee, and a table-only column should be read cautiously. Heavier multi-axle trucks sit much lower. One owner on a heavy-truck forum reported roughly 3 km/L on highways. For how the 1615, 1618, and 1617 compare on power and service, see the model comparison (/blog/tata-1615-vs-ashok-leyland-1618-vs-bharat-benz-1617).

What Changes Real Mileage

Load, route, driving style, tyre pressure, maintenance, and engine age all move the number. A full load and a ghat section will not match an empty highway run. See the GVW and payload guide (/blog/gvw-ulw-payload-truck-explained) and the tyre guide (/blog/truck-tyre-life-retreading-cost-per-km). A used truck can also differ from a new one of the same model, so measure it instead of copying the brochure.

Fuel Cost Per Km

Cost per km = diesel price per litre divided by kmpl. This example uses an assumed ₹90 per litre, not today's pump price. At 8 kmpl that is ₹11.25 per km. At 10 kmpl it is ₹9.00 per km. At 12 kmpl it is ₹7.50 per km. A gap of about 2 kmpl changes fuel cost by roughly ₹2 to ₹3 per km in this example. Put in your own diesel price before you use the figure.

How to Measure Mileage

1. Fill the tank completely at the same pump and note the odometer.
2. Drive a normal trip with a typical load.
3. Fill the tank completely again. Note the litres added and the new odometer reading.
4. kmpl = kilometres driven divided by litres added.
5. Repeat across 3 to 4 fills, including loaded and empty legs, then average them.

On a Used Truck

Ask the seller for actual kmpl on their routes, loaded and empty, and compare that with the stated range for the model. A large gap is a question, not an automatic no. Running-cost context for the whole truck is in the total cost of ownership guide (/blog/truck-total-cost-of-ownership-india-used-commercial-vehicle).
