Maruti Suzuki said on Saturday that E20 ethanol-blended fuel causes no damage to cars manufactured before 2023.
The announcement aims to calm public anxiety regarding the transition to higher ethanol blends. Many vehicle owners feared that fuel containing 20% ethanol [1] would corrode engines designed for the previous 10% standard.
Rahul Bharti, Corporate Affairs Senior Executive Officer at Maruti Suzuki India, addressed these concerns during a Press Information Bureau press conference in New Delhi. He said that the fuel is safe for older vehicles and does not lead to mechanical failure.
"E20 fuel causes no damage to cars manufactured before 2023," Bharti said [1].
India mandated E20 compliance for new vehicles starting in 2023 [2]. This shift was designed to reduce carbon emissions and decrease reliance on imported petroleum. However, rumors persisted that older models, which were originally engineered for E10 fuel, would suffer from accelerated degradation.
Bharti dismissed these reports, noting that the fuel does not impact the long-term integrity of the engine components. He specifically addressed the risks of material decay and mechanical friction.
"There is no problem in terms of wear & tear, corrosion with E20 fuel," Bharti said [3].
Industry experts have defended the rollout, citing years of testing to ensure compatibility across different vehicle generations. The company's statement suggests that the chemical properties of the 20% blend do not either compromise the seals, or the metal surfaces of pre-2023 engines [1].
"E20 fuel is safe for older vehicles," Bharti said [4].
“"E20 fuel causes no damage to cars manufactured before 2023."”
This clarification is critical for the Indian automotive market, where a vast number of legacy vehicles remain in use. By confirming that E20 fuel is compatible with E10-designed engines, Maruti Suzuki is attempting to prevent a mass panic of vehicle owners and avoid a potential surge in premature car replacements. This supports the government's broader energy strategy to scale ethanol blending without disrupting the existing transport infrastructure.
