Govt admits E20 impact on pre-2023 vehicle mileage
The government has admitted that E20 fuel, which has a higher ethanol content, can cause a small decrease in fuel efficiency (about 3-5%) for cars made before 2023.
However, they say that driving habits, tire pressure, and maintenance have a bigger effect on mileage than the type of fuel.
The government also mentioned that E20 fuel helps make engines cleaner and more efficient without causing any damage to vehicles.
They shared data from car and bike manufacturers showing that no extra damage was found in vehicles using E20 fuel.
The government has not decided to increase ethanol blending beyond 20% in petrol or to start blending it in diesel.
Government acknowledges a 3-5% reduction in fuel economy for pre-2023 vehicles using E20 fuel.
E20 fuel contributes to cleaner engine operation and improved emissions performance.
No abnormal wear and tear or compatibility issues reported with E20 fuel.
Manufacturer data shows no higher incidence of damage in vehicles using E20 fuel.
Government has not decided to increase ethanol blending beyond 20% in petrol or introduce it in diesel.
