'It’s crazy’: Drivers reporting ‘juddering’ from their car after using new E10 petrol

E10 fuel was launched onto forecourts at the beginning of September in a bid to lower vehicle emissions. The Department of Transport said it could cut transport CO2 emissions by 750,000 tonnes per year, which is the equivalent of taking 350,000 cars off of UK roads.

Since then, drivers have reported many issues when using the new petrol, from their engine spluttering to lower fuel economy.

One driver on Twitter, Laura Broadbent, said: “Hi @SEATUK – have you had reports of the new E10 fuel affecting Seat Ibiza FR?

“Have lots of juddering since using it and it’s fine when I upgrade my petrol to E5!

In response, Seat’s official Twitter account responded saying it was “not a known issue” and advised the driver to book an inspection so the root cause can be found.

The Government stated that E10 petrol can marginally impact fuel economy when in use.

It is believed to only be around a one percent reduction, although it would be “almost unnoticeable” to most drivers.

Express reader Juan Sinclair said they had noticed a slight benefit from E10 petrol.

They claimed: “I haven’t noticed any difference with my ’05 Citroen, same performance, much smoother under 3,000 RPM and slightly better fuel consumption because I’m not down-shifting as much.

“However, the owner of my local garage says that some brands really don’t like it.

“He’s also seeing issues with vehicles that either weren’t being maintained properly or have been fitted with cheapo pattern parts.

“I think we need a lot more info about this because it sounds to me more like a car problem than a fuel problem.”

E10 petrol is blended with up to 10 percent renewable ethanol and made up of materials such as low-grade grains, sugars and waste wood.

The Government has praised E10 as being a “greener” fuel as a result.

At the time of its launch, Transport Secretary Grant Shapps spoke of the benefits of E10, especially in the lead up to COP26.

He said: “Every journey matters as we drive forward the green industrial revolution, which is why the rollout of E10 is so important.

“It’ll help us cut road greenhouse gas emissions and meet our ambitious net zero targets.”
