Why Is Indian Oil Warning Motorists About Ethanol-Blended Petrol and Water Contact?
About the Advisory
Indian Oil has begun displaying public notices at several fuel stations across India, alerting motorists that petrol now contains up to 15–20% ethanol. This change aligns with the Government of India’s E20 program — a national drive to blend petrol with ethanol for reducing import dependence and carbon emissions.
What the advisory says: Petrol now contains 15–20% ethanol. Customers are advised to ensure water does not come in contact with petrol, especially during car washes or rainy conditions. The notice highlights ethanol’s moisture-absorbing nature and recommends caution during refuelling and maintenance.
What Ethanol Blending Means for Drivers
Ethanol is an alcohol-based biofuel derived mainly from sugarcane and corn. When mixed with petrol, it improves combustion and helps reduce emissions. India’s E20 program was rolled out nationwide in 2023 and aims for 20% blending by 2025. However, ethanol is hygroscopic — meaning it can absorb moisture from the air. This property, while harmless in most conditions, can cause separation of water and fuel if stored improperly or exposed to heavy moisture for long durations.
Official clarification: The Petroleum Ministry has clarified that E20 petrol is safe for use in compliant vehicles and does not affect insurance validity. Claims that E20 damages engines or causes instant breakdowns are unfounded. However, motorists should ensure tanks are sealed properly and avoid filling from stations with visible water accumulation near nozzles or manholes.
Ground Reality at Petrol Pumps
Fuel dealers, especially in coastal and humid regions, have reported challenges during the monsoon. They say water condensation and storage humidity sometimes lead to complaints about misfires or poor mileage. Industry bodies have requested seasonal relaxation of ethanol blending during heavy rains, but officials maintain that modern dispensing systems are designed to handle humidity safely.
Practical tip: If you notice unusual engine behavior after refuelling — sputtering, hesitation, or reduced pickup — it’s advisable to get the fuel checked for water content. Always refuel at reputed outlets that maintain high storage standards.
Expert Observation
Indian-Share-Tips.com’s Technical Analyst Gulshan Khera, CFP®, who is also a SEBI Regd Investment Adviser, observes that the ethanol blending initiative marks an important shift toward sustainable energy. “While ethanol reduces carbon intensity, motorists must adapt to new fuel chemistry through awareness and preventive care,” he notes. Proper tank sealing, routine filter cleaning, and avoiding refuelling during heavy rainfall are practical steps for long-term vehicle health.
For readers tracking market developments in the energy and automotive sectors, ethanol blending has implications for listed refiners, sugar manufacturers, and vehicle OEMs. The shift toward biofuel usage is expected to boost ethanol producers’ earnings and align India closer to its 2070 net-zero emission target.

How Drivers Can Stay Protected
✅ Always refuel at trusted stations.
✅ Avoid topping off the tank immediately after rain.
✅ Keep the fuel cap tightly sealed.
✅ Schedule regular maintenance checks.
✅ If your car is older than 10 years, verify E20 compatibility with your dealer.
Investor Takeaway
The ethanol blending drive is a long-term sustainability reform, not a short-term risk. It may temporarily cause adjustment issues for certain engines, but overall, it supports energy diversification and rural income through higher sugarcane demand. Investors can monitor ethanol producers, refinery upgrades, and flex-fuel vehicle launches for medium-term opportunities.
