India's nationwide rollout of E20 ethanol-blended petrol has raised concerns among vehicle owners, but industry experts have firmly stated that the fuel is safe—even for older vehicles manufactured before the mandate. Speaking at a press conference, executives from leading automakers and the former chairman of Engineers India Limited detailed years of scientific testing and a phased approach that led to the country achieving 20% ethanol blending by December 2025, five years ahead of schedule, according to Business-Today.
Background and Rollout
The ethanol blending programme was introduced through a phased, science-based approach after extensive consultations with automakers, testing agencies, and other stakeholders, Business-Today reported. Former Engineers India Limited chairman and managing director Vartika Shukla stated that ethanol blending in petrol rose from approximately 1.5% in 2013-14 to 20% by December 2025, enabling India to achieve its target five years ahead of schedule. "This ethanol blending in petrol has been not done overnight, it is a measured scientifically driven step-by-step process," she said. Shukla added that the programme was supported by "scientific evidence, extensive testing" conducted by automotive manufacturers, the Automotive Research Association of India (ARAI), and the Society of Indian Automobile Manufacturers (SIAM). She noted that the initiative follows practices adopted by countries including the US, Brazil, Canada, and Germany.
| Period | Ethanol Blending in Petrol |
|---|---|
| 2013-14 | ~1.5% |
| December 2025 | 20% |
Vehicle Safety and Testing
Vikram Gulati, country head and executive vice president of corporate affairs and governance at Toyota Kirloskar Motor, said vehicles and fuels in India undergo rigorous testing and certification. "Vehicles that are made available to consumers are extremely well engineered, well designed and have a very immense element of oversight through technically sound testing agencies," he said. Describing ethanol as "a very good fuel," Gulati noted it delivers high performance while reducing carbon emissions. Rahul Bharti, senior executive officer of corporate affairs at Maruti Suzuki India, addressed concerns about older vehicles originally designed for E10 fuel. "As a manufacturer, we have tested E10 cars... on E20 fuel for all parameters and we have not found anything of concern," he said. Bharti stated that the company built sufficient safety margins into vehicle design and testing to ensure no issues related to wear and tear, corrosion, or component life, even for pre-2023 vehicles using E20 fuel. Ashutosh Verma, chief business officer of Hero MotoCorp, said the company's extensive service data supports safety. "We analyze crores of service data that we have, and... there is no incidence whatsoever of any higher damage with vehicles that run on E20 than the vehicles that were running on fuels prior to E20," he stated.
Reducing Crude Oil Dependence
The ethanol blending programme has contributed to lowering India's crude oil imports, reducing the country's vulnerability during recent geopolitical disruptions, according to Business-Today. Vartika Shukla highlighted that the initiative helped cushion consumers and the economy when global crude oil supplies came under pressure. Vikram Gulati added that ethanol is a zero-carbon fuel derived from plants, making it beneficial in the context of climate change. The programme's success aligns with India's broader energy security goals, as blending reduces the volume of petrol that must be imported.
The E20 mandate, now in effect nationwide, is the result of years of collaboration between government agencies, automakers, and testing bodies. Industry experts continue to monitor the fuel's performance but maintain that the scientific evidence supports its safe use across all vehicle vintages. For commodity stakeholders, the rapid scaling of ethanol blending signals sustained demand for ethanol feedstock and a long-term shift in India's fuel mix, with potential implications for global ethanol trade flows and crude oil import requirements.
