E85 fuel introduction in India: what it means for motorists

With E85 fuel launched at the Indian Oil retail outlet in New Delhi last week, the Union government is pushing for ethanol blending in the fuel as a means of reducing import costs in times of the current crisis in West Asia and reducing dependence on fossil fuels.

The central government’s aggressive push for higher ethanol blending also fits in with India’s goal of net zero greenhouse gas emissions by 2070.

So far, the rollout has begun at 48 public sector retail outlets in the country, giving flex-fuel vehicle users access to this cleaner fuel.

Speaking at the launch event of E85 fuel in New Delhi, Union Minister for Petroleum and Natural Gas Hardeep Singh Puri said, “Ethanol blending has increased from 1.53% in 2014 to 20% today, achieving the target five years ahead of schedule, saying this transformation has helped save more than $1.84 trillion out of nearly 20 billion metric million in foreign currency oil imports”. Petrol with ethanol is also exempt from central excise duty,

Currently, India has more than 26 million registered two-wheelers, making it the most dominant form of road transport in the country. Approximately 50 million registered four-wheelers (including passenger cars, jeeps, taxis and commercial goods carriers) ply its roads.

Here we break down the details of E85 fuel and its impact on costs:

What are E85 and E100 fuels?

E85 and E100 are high ethanol fuel blends that contain higher amounts of anhydrous (anhydrous) ethanol. While E85 consists of 85% ethanol and 15% gasoline, E100 contains 93-95% ethanol. In addition, E85 fuel is introduced for use in flex-fuel vehicles. The initiative aims to facilitate the adoption of Flex-Fuel Vehicles (FFVs), which are capable of running on ethanol blends from E20 to E100 without limiting consumers to a single blend.

Aiming for nationwide expansion, E85 fuel should be available in 500 retail outlets by December 2026 and around 5,000 retail outlets by December 2027. The Ministry of Petroleum was mulling plans to increase the blending level of ethanol aggregate in India to nearly 26 percent by 2030-31.

What are flexible fuel vehicles?

A flex-fuel vehicle is typically understood as a vehicle that has the ability to run on different fuel variants. In the current context, the FFV should be able to run on E 20, E 85 and E 100 fuels. The vehicle’s engine and fuel system automatically detect the ethanol content and adjust fuel injection and ignition timing accordingly. FFVs have special fuel sensors that can detect the percentage of fuel in the vehicle. Later, engine control software optimizes performance for the specific quality of fuel injected into the vehicle.

Additionally, these vehicles come with fuel system components that prevent corrosion from high ethanol fuel.

Can regular vehicles (or E20 vehicles) use E85 fuel?

The straight answer is ‘No’. This is because these vehicles must require special fuel-flex engines with significant changes to the fuel system and engine calibration. An E20-compliant vehicle means that the engine and fuel system are hardened enough to handle up to 20% ethanol blended into regular gasoline.

The E85 formula requires completely different engine tuning, larger injectors, ethanol-resistant materials throughout the fuel system, and sensors that can detect the mixture ratio and adjust on the fly.

Putting E85 into an E20 rated vehicle would risk running lean, corroding the fuel system and damaging the engine over time.

For the uninitiated, vehicles manufactured under Bharat Stage VI (Phase-II) from April 23 onwards are E20 compatible as mandated by the government.

Fuel-flex vehicles for consumers

The automotive industry in India is in its nascent stage when it comes to flex-fuel vehicle catering options for the general consumer. So far, Hero Motocorp, Suzuki and Maruti Suzuki Motocorp have released fewer models that comply with E85 fuel standards.

Fuel Cost Comparison: E85 vs Gasoline

Here is the breakdown according to the current fuel price in Delhi:

Fuel Price/Litre E20 (regular petrol) ₹ 102.12 E85 ₹ 82.12

E85 costs ₹20 less than regular E20 petrol in Delhi. However, ethanol has a lower energy density than gasoline, so a flex-fuel engine will burn more of it to cover the same distance. E85 compatible vehicles can be expected to get 25-35% less fuel consumption than an equivalent E20 vehicle.

As noted above, E85 actually costs more per mile assuming normal fuel economy.
