Everything you need to know about E10 Petrol

E10 petrol is the new petrol that has been introduced to the UK from xxxx. You will start to see it at petrol pumps and you may be wondering what this means for your car. Look no further, we have everything you need to know about E10 petrol.

What is E10?

E10 petrol contains up to 10% renewable ethanol, which will help to reduce CO2 associated with petrol vehicles and tackle climate change. This is all part of the UK Governments drive to hit their emissions targets as part of their major pledge to helping to reduce the impact of climate change.

Petrol in the UK currently contains up to 5% renewable ethanol (known as E5). E10 petrol is already widely used around the world, including across Europe, the US and Australia. It has also been the reference fuel against which new cars are tested for emissions and performance since 2016.

Reducing emissions

CO2 is one of the greenhouse gases that contribute to climate change and the main benefit of E10 petrol is that it reduces overall levels of CO2-based vehicle emissions. By blending petrol with up to 10% renewable ethanol, less fossil fuel is needed, helping us reduce carbon emissions.

The introduction of E10 petrol at UK forecourts could cut transport CO2 emissions by 750,000 tonnes a year – the equivalent of taking 350,000 cars off the road, or all the cars in North Yorkshire. Renewable fuel blends, such as E10 petrol, are generally introduced to reduce overall CO2 emissions. They have little impact on emissions associated with air quality and public health.

The production of renewable ethanol for blending with fossil petrol also results in valuable by-products, including animal feed and stored CO2.

Fuel Efficiency

Using E10 petrol can slightly reduce fuel economy (the number of miles you are able to drive on a gallon of fuel). You may see a reduction of around 1%, but it is unlikely to be noticeable in everyday driving.

Other factors – such as your driving style or driving with under-inflated tyres or a roof rack – have a much more significant impact on fuel economy than using E10 petrol.

The Big question - Is your car compatible?

Around 95% of petrol-powered vehicles on the road are compatible with E10 petrol and this figure is increasing all the time.

All new cars manufactured since 2011 are compatible with E10 petrol, and most cars and motorcycles manufactured since the late 1990s are also approved by manufacturers to use E10.

The following vehicles, however, may not be compatible with E10 petrol:

  • classic, cherished and older vehicles
  • some specific models, particularly those from the early 2000s
  • some mopeds, particularly those with an engine size of 50cc or under

You can check whether your vehicle is approved to use E10 petrol using our E10 vehicle checker, which covers cars, motorcycles and mopeds on the Gov.uk website

Classic vehicles

One thing we noticed, many manufacturerers of classic cars are not listed in the vehicle checker. Where older brands are no longer trading, the site cannot provide specific information on vehicle compatibility.

Owners of vehicles not listed in the vehicle checker should continue to use E5 (97+ octane) petrol, which will remain available in the ‘super’ grade.

One important factor to bear in mind is that the E10 can be slightly more corrosive to parts and rubber lines, the key watch out is also around the fact that it absorbs more water than normal fuel and therefore if your pride and joy is standing idle for months its vital to make sure you do not have E10 in the tank!
