Ethanol-blended petrol faces complaints of engine damage across India

Across India, car and motorcycle owners are reporting problems with their vehicles after using petrol blended with 20% ethanol, known as E20. Common complaints include clogged fuel injectors, damaged fuel pumps, and contaminated petrol. The government introduced E20 as part of a plan to reduce pollution and cut oil imports. However, the transition has sparked debate about whether ethanol is actually causing these issues. Some experts argue that ethanol can absorb water and attract dirt, leading to deposits and corrosion in engines not designed for higher ethanol blends. They also point out that older vehicles may not be compatible with E20. On the other hand, fuel companies and some automakers say the problems are due to improper maintenance or pre-existing contamination, not the ethanol itself. They insist that modern vehicles are built to handle up to 20% ethanol. Consumer groups are calling for clearer information and better testing. The government has not yet released official data on the number of complaints. As the rollout of E20 continues, drivers are advised to check their vehicle's compatibility and use fuel from trusted sources. The debate over ethanol's role in engine damage remains unresolved, with both sides presenting competing claims.
