What to do if your Santro is not E20 compliant
Regular Servicing: Get your fuel system inspected at regular intervals. Ask your mechanic to check fuel lines, seals, gaskets, and O-rings for signs of wear.
Fuel Filter Replacement: Replace your fuel filter more frequently, every 15,000-20,000 km instead of 30,000 km.
Monitor Mileage: Track your fuel efficiency. If you notice a drop beyond 10%, consult your service centre.
Consider Retrofit: Some service centres offer ethanol-compatible fuel system component upgrades. Costs vary from Rs 2,000-8,000 depending on the vehicle.
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.
