    About Indian Fuel Types

    Common fuels

    • Petrol (Gasoline)
    • Diesel
    • CNG and AutoLPG (where available)
    • Premium petrols: XP95, XP100

    What is E20?

    E20 is petrol with 20% ethanol. Use it only in E20‑compliant or flex‑fuel vehicles. Older engines may see slightly lower mileage.

    How we calculate cost

    Formula: distance ÷ mileage × city fuel price.

    • Choose fuel type and city.
    • Enter one‑way distance and mileage; toggle round trip if needed.
    • Or skip the city list and type the pump price yourself.

    Why prices vary by city

    • State VAT and local cess — already inside the pump price we use
    • Freight and dealer commission
    • Crude price and INR–USD exchange rate

    Benefits, disadvantages and engine compatibility

    Petrol

    • Benefits: Refined, quieter engines; wide availability.
    • Disadvantages: Lower mileage than diesel.
    • Engines: Spark‑ignition (SI). E20 requires E20‑rated components.

    Diesel

    • Benefits: Higher torque and mileage for long trips.
    • Disadvantages: Higher NVH; DPF care on short trips.
    • Engines: Compression‑ignition (CI) with turbo & after‑treatment.

    CNG

    • Benefits: Low running cost and emissions.
    • Disadvantages: Reduced boot space; slight power drop.
    • Engines: Bi‑fuel SI engines (Petrol/CNG) with factory or approved kits.

    AutoLPG

    • Benefits: Cleaner than petrol; good urban availability in some cities.
    • Disadvantages: Fewer stations than petrol/diesel; range anxiety.
    • Engines: SI engines with LPG kits (homologated).

    E20 (20% ethanol petrol)

    • Benefits: Lower fossil fuel use; potential price advantage.
    • Disadvantages: Slightly lower mileage; not for non‑compliant vehicles.
    • Engines: E20‑compliant SI engines; check fuel cap/manual.

    Premium petrol (XP95/XP100)

    • Benefits: Helps high‑compression/turbo engines avoid knock.
    • Disadvantages: Costlier; limited gains on regular engines.
    • Engines: SI engines designed for higher octane (check manual).

    More about fuel pricing in India

    What drives price changes?

    • International crude benchmarks (Brent/WTI)
    • INR–USD exchange rate
    • Central excise duty and state VAT
    • Freight, logistics, dealer commission

    Improve your mileage

    • Keep tyres at recommended PSI
    • Smooth throttle; avoid sudden braking
    • Remove unnecessary weight/roof racks
    • Service regularly; clean air filter, right oil grade

    E20 compatibility

    Most new vehicles (2023+) are E20‑ready. Check your fuel lid/manual or manufacturer website.

    What’s in a litre price?

    Base fuel price + central excise + dealer commission + state VAT and local levies. Composition varies by state and over time.

    FAQs
    • How often do prices change? Depends on market conditions and OMC policies.
    • Why is CNG priced in kg? Energy content differs; vehicles report mileage in km/kg for CNG.
    • Is premium petrol worth it? Helps engines designed for higher octane; minimal gains otherwise.
    • Why no official live API? No free public API from OMCs; we maintain a city list from public reports.
