One reader said they would “pick E5 every time” as it was “better for combustion and efficiency”. Readers were reacting to motoring YouTube channel ‘Number 27’ who warned E10 could come with fuel efficiency issues.
Reader Backfire added: “This is what happens when politicians, not engineers, get involved with this stuff.
“All these ‘green’ panic moves will cost the country, and therefore us, a fortune.”
Other road users likened the latest E10 update to Labour’s ‘dash for diesel’ in 2001.
Motorists were given financial incentives for cars that emitted fewer CO2 emissions.
E10 fuel was launched back in September in a bid to reduce vehicle emissions.
The DfT has previously said the new petrol would reduce CO2 emissions by around 750,000 tonnes.
They warned this would be the equivalent of removing 350,000 vehicles off the road in one go.
The RAC warns cars built before 2002 are advised to not use E10 fuel as they will likely be incompatible.
However, E10 compatible parts were only mandated from 2011 meaning many more older vehicles may be unable to use it.
