How much petrol is needed for 400 km?
The petrol required for 400 km depends only on your car's mileage. The formula is simple: distance ÷ mileage = litres needed. At 15 km/l (typical hatchback or sedan), a 400 km trip needs about 26.7 litres. A more efficient car at 20 km/l drops this to 20 litres, and a diesel SUV at 14 km/l will use about 28.6 litres. Highway driving usually returns 10–15% better mileage than city traffic, so use a slightly higher km/l figure for outstation trips.
400 km trip cost examples
Worked example: Delhi to Agra and back (~440 km)
- Car: Maruti Swift petrol, real-world mileage 18 km/l
- Petrol required for 400 km: 400 ÷ 18 = 22.2 L
- Petrol price: ₹106/L → fuel cost = ₹2,355
- Yamuna Expressway tolls (return): ~₹830
Other 400 km scenarios that use the same calculation: Bengaluru–Mysore–Coorg loop (~400 km in a Hyundai Creta diesel at 17 km/l burns ~23.5 L = ~₹2,185), Mumbai–Nashik–Igatpuri–Mumbai (~400 km weekend loop), and a city sales rep with 4–5 client visits across a metro area summing to ~400 km. For an exact number, plug your car's mileage into the calculator above.

Most diesel cars deliver 2–4 km/l better mileage than the petrol version of the same model, so the real diesel saving on 400 km is usually larger than the per-litre price gap suggests. Even so, the per-trip diesel saving on 400 km is typically only ₹400–₹800 — small enough that a petrol or CNG car often makes more sense for occasional weekend trips. For frequent 400 km+ runs, diesel starts to pay off.
How to plan a 400 km road trip budget
- Add a 5–10% buffer over the calculated litres for AC use, traffic, and headwind.
- Most 400 km Indian highway routes have 2–4 NHAI toll plazas — budget ₹350–₹700 one-way; expressways such as Yamuna, Mumbai–Pune or Delhi–Meerut charge more per km.
- One refuel stop is usually enough — most cars cover 400 km comfortably on a single tank, but a quick top-up at the midway pump avoids running on reserve.
- For round trips, double the litres. Toll plazas often charge a discounted return-trip toll if you cross the same plaza within 24 hours.
- Use the trip fuel calculator above to compare petrol, diesel, and CNG cost for your exact car and city fuel rate before you leave.
