What to do if your Sport is not E20 compliant
Fuel System Inspection: Get fuel lines, seals, gaskets, and O-rings checked at every service. Ethanol degrades non-resistant rubber components over time.
Fuel Filter Replacement: Replace your fuel filter every 10,000-15,000 km instead of the usual 20,000 km. Ethanol loosens existing deposits.
Monitor Mileage: Track your fuel efficiency. A 3-5% drop is normal on E20. If it exceeds 10%, consult your service centre.
Consider Upgrades: Some service centres offer ethanol-compatible fuel system parts. Royal Enfield offers E20 conversion kits at around Rs 1,700 for select older models.
Premium Fuel Option: Indian Oil XP100 (100-octane, ethanol-free) is available at select pumps at Rs 150+/litre for those who want to avoid E20 entirely.

Is TVS Sport E20 compatible?
The TVS Sport does not have official E20 compatibility confirmation. This model predates the April 2023 E20 mandate or was discontinued before TVS confirmed their E20-ready lineup.
Can I use E20 petrol in TVS Sport?
Using E20 in a non-confirmed Sport carries risk. Ethanol can degrade rubber fuel lines, swell seals, and cause injector deposits in bikes not designed for it. Get your fuel system inspected and consider replacing rubber components with ethanol-resistant alternatives.
What should I do about E20 with my TVS Sport?
Inspect fuel lines, hoses, and seals every 6 months. Replace fuel filters more frequently (every 10,000 km). Use fuel additives to slow ethanol-related corrosion. Contact TVS service for model-specific guidance on E20 readiness.
