300 km Petrol Cost in India
Quick Answer
300 km at 15 km/l = ~20 litres. At ₹106/litre = ~₹2,120 petrol cost. A diesel car at 18 km/l takes ~16.7 L = ~₹1,550. Use the trip fuel calculator below for your exact mileage and tolls.

How much petrol is needed for 300 km?
The petrol required for 300 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 300 km trip needs about 20 litres. A more efficient car at 20 km/l drops this to 15 litres, and a diesel SUV at 14 km/l will use about 21.4 litres. Highway driving usually returns 10–15% better mileage than city traffic, so use a slightly higher km/l figure for outstation trips.
300 km trip cost examples
Worked example: Delhi to Jaipur (one-way ~300 km)
- Car: Honda City petrol, real-world mileage 17 km/l
- Petrol required for 300 km: 300 ÷ 17 = 17.65 L
- Petrol price: ₹106.5/L → fuel cost = ₹1,880
- NHAI tolls on NH-48 (2–3 plazas): ~₹350
Another quick scenario: a same-day client visit from Mumbai to Pune and back (~300 km round trip) in a Maruti Swift petrol at 22 km/l burns roughly 13.6 L of petrol — about ₹1,440 in fuel plus highway tolls. Weekend airport runs from peripheral cities (e.g. Pune to Mumbai airport and back) fall in the same 250–320 km bracket and use this same calculation.

Most diesel cars deliver 2–4 km/l better mileage than the petrol version of the same model, so the real diesel saving on 300 km is usually larger than the per-litre price gap suggests. Even so, the per-trip diesel saving on 300 km is typically only ₹300–₹600 — small enough that a petrol or CNG car often makes more sense for occasional weekend trips.
How to plan a 300 km road trip budget
- Add a 5–10% buffer over the calculated litres for AC use, traffic, and headwind.
- Most 300 km Indian highway routes have 1–3 toll plazas — budget ₹250–₹500 in tolls one-way; expressways such as Yamuna or Mumbai–Pune charge more per km.
- For same-day round trips, double the litres. Toll plazas often charge a discounted return-trip toll if you cross the same plaza within 24 hours.
- If you split fuel + toll among co-passengers, divide total trip cost by passenger count for an honest per-person figure.

Frequently asked questions
How much petrol is required for 300 km?
300 km divided by your car's mileage gives the litres needed. At 15 km/l, 300 km needs 20 litres. At 18 km/l it drops to 16.7 litres, and at 22 km/l (an efficient compact petrol or modern diesel) you only need about 13.7 litres. Use the trip fuel calculator above for your exact car.
What is the fuel cost for a 300 km car trip?
For a typical petrol hatchback at 15 km/l with petrol at ₹106/litre, a 300 km trip costs about ₹2,120 in fuel. A diesel sedan at 18 km/l with diesel at ₹93/litre costs roughly ₹1,550. Add ₹250–₹500 for highway tolls if your route has 1–3 toll plazas.
Is 300 km better for petrol or diesel?
For a single 300 km trip, the diesel saving is usually only ₹300–₹600 because diesel's higher capital cost is amortised over thousands of kilometres. If you mostly drive shorter weekend trips, a petrol or CNG car often makes more sense. For frequent 300 km+ runs, diesel starts to pay off.
How much toll should I budget for a 300 km highway trip?
Most Indian 300 km highway routes have 1–3 NHAI toll plazas. Budget ₹250–₹500 one-way for cars; expressways such as Yamuna Expressway or Mumbai–Pune charge more per km (₹450–₹700 for a 300 km segment). FASTag is mandatory and gives faster passage at the gate.
Can I use this calculator for a round trip of 300 km each way?
Yes. Toggle the round-trip option in the planner above to double the distance to 600 km, or run a 300 km calculation and multiply the fuel by two. Toll plazas often charge a discounted return-trip toll if you cross the same plaza within 24 hours, so the round-trip toll is usually less than 2× the one-way toll.
Which car mileage should I use if I don't know my exact figure?
Use the manufacturer's ARAI mileage and reduce by 10–15% for real Indian conditions. For example, a car rated 20 km/l usually delivers 17–18 km/l on highway. If you are unsure, start with 15 km/l for petrol cars and 18 km/l for diesel — that is the typical real-world average for a 300 km mixed run.
