‘No benefit’: E10 petrol slammed over fuel economy issues as drivers struggle to find E5

3 mins read


When E10 was introduced in September, there were fears that the increased ethanol content could have an effect on the vehicle. A number of car mechanics had warned that the new petrol could damage rubber and metal seals.

Express.co.uk reader Brock.the.Elder spoke of how the new grade of petrol is affecting how their car runs.

They claimed: “Had my new car a week and on E10 as recommended fuel, it can use both so mixing them would be a problem.

“However, sometimes the car is sat on the drive for a prolonged amount of time without use so as a precaution I use E5 until the problems with this new fuel are ironed out, if ever.

“Question is – Is this fuel the same blending as in Europe?

Both petrol and diesel hit their highest prices ever in the past few weeks, with latest RAC figures showing a further increase from the peak.

They found the average price of a litre of petrol to be 145.06p and a litre of diesel costing drivers 148.61p.

Some drivers have also spoken about returning to using E5 fuel, which was reclassified as super unleaded when E10 was introduced, now costing an average of 156.13p.

Another user, Tony Margiocchi, said: “I have found that my car does fewer MPG, anyone else found that?

“As a result it seems the only people to benefit from this con is the fuel companies and car manufacturers and soon probably garages for engine repairs. 

“Guess this latter bit is part of Boris’s thinking that these green initiatives will create jobs.”

E10 was introduced on September 1 to help lower the rate of emissions released by vehicles.

It is blended with up to 10 percent renewable ethanol and could cut 750,000 tonnes per year, which is the equivalent of taking 350,000 cars off of UK roads.

The Government warned drivers that using E10 can marginally impact fuel economy, generally believed to be around one percent.
