E20 Petrol Debate: MP Questions Government Over Engine Damage Claims
There's a big discussion happening in India about E20 petrol, which is petrol mixed with ethanol.
The government says there's no proof that this mix is causing widespread problems with car engines.
But a Member of Parliament named John Brittas thinks the government is being sneaky by saying 'widespread' problems don't exist, which doesn't mean there are no problems at all.
He also points out that there are warnings at petrol stations about water contamination in this type of petrol.
The government says they've done a lot of research and talking to experts before making this petrol blend.
But people are worried because E20 petrol might make cars use more fuel and not perform as well.
Member of Parliament John Brittas accused the government of avoiding the issue of engine damage from ethanol-blended petrol by focusing on the word 'widespread'.
The government claims there is no verified evidence of widespread engine damage or performance issues due to ethanol blending.
Brittas argues that the absence of widespread failures does not mean there are no failures at all.
Public notices at petrol stations warn about water contamination in E15-E20 petrol, contradicting the government's claim that no advisories have been issued.
E20 petrol can reduce fuel efficiency because ethanol contains less energy than petrol.
