YOUR MILEAGE DROPPED? The Hidden Truth Behind India’s E20 Fuel ExperimentIs your bike or car giving lower mileage after the E20 fuel rollout? Is ethanol really better, or are we part of a nationwide experiment?
In this video, we break down the science behind India’s ethanol blending program using official data and real-world comparisons. You’ll learn why petrol contains 34 MJ/L of energy while ethanol contains only 21 MJ/L, and how that difference can affect fuel economy. We also explain why E20 may reduce mileage compared with traditional petrol, why ethanol attracts moisture, and how humidity can contribute to corrosion and fuel system issues in some vehicles.
We also compare India’s rapid rollout with countries like Brazil, the United States, and Thailand, showing how each adopted ethanol blending differently over time. Finally, we fact-check the viral claim that ants are attracted to ethanol-blended fuel and explain what actually happens during ethanol production.
This video is intended to explain the technology, the policy, and the science behind ethanol-blended fuels so you can make informed decisions.
