Drivers are being urged to check that their vehicles will be compatible with the new eco-friendly E10 fuel being launched in the UK this Autumn.
The new E10 fuel is scheduled to be introduced from September 2021, replacing E5 fuel as the standard petrol grade.
In preparation for this The Department for Transport (Dft) is running a nationwide E10 fuel UK awareness campaign this summer to inform motorists of the fuel changes, promote the benefits of E10 petrol and to advise drivers to use the online checker to see if their vehicle will run on the new E10 fuel.
The campaign will feature on fuel pump labels throughout the country. It will also incorporate targeted digital, radio and social media advertising in a bid to get drivers ready to use e10 petrol later this year.
The Department for Transport (Dft) is launching a nationwide awareness campaign from mid-June to inform motorists of the fuel changes, promote the benefits of E10 petrol and to advise drivers to use the online checker to see if their vehicle will run on the new E10 fuel.
E10 is a biofuel made up of 90% regular unleaded and 10% ethanol.
As the new E10 fuel, contains twice as much renewable ethanol as existing E5 petrol, it makes the fuel less polluting compared with the current E5 petrol.
Ethanol is an organic chemical compound, naturally produced by the fermentation of sugars from a range of plants, including sugarcane and grains.
The plants grown to become the biofuel will reportedly absorb more carbon dioxide as they grow, than what will be released into the air during fuel production and combustion.
This makes ethanol a more environmentally friendly compound than traditional fuels such as petrol (gasoline) and diesel fuel. As ethanol partially offsets the greenhouse gas emissions produced by its production and use,
Some other key benefits of ethanol are:
- Ethanol is non-toxic
- Ethanol is easy to source
- Ethanol production results in valuable by-products such as high protein animal feed and stored CO2 which can help reduce the need to import these products
E10 petrol is already widely used around the world, including across Europe, the US and Australia.
As mentioned, ethanol partially offsets the greenhouse gas emissions produced by its production and use. Converting to E10 fuel as the standard petrol grade will potentially cut transport CO2 emissions by 750,000 tonnes a year.
The UK government estimates the use of E10 petrol could cause a drop in carbon emissions equal to the effect of taking 350,000 cars off the road every year.
E10 petrol can slightly reduce fuel economy (the number of miles you are able to drive on a gallon of fuel).
However, most drivers are unlikely to notice much difference when using E10 fuel in place of E5 as the fuel efficiency reduction is only around 1% - 1.6% - For the average driver, this equates to no more than half a tankful per year.
Other factors such as driving style or carrying unnecessary additional weight would have a more significant impact on fuel economy.
Once E10 is introduced, it’s expected to be the cheaper petrol out of E10 and E5 as it will become the standard petrol grade fuel type across UK forecourts so, widely available.
It is estimated that some 634,000 cars will not be compatible with E10 fuel when it launches in September.
Whilst all cars produced after 2011 are pre-approved to use the E10 petrol fuel. Older vehicles, including classic cars and some from the early 2000s are not compatible with E10 fuel and will continue to need E5 fuel.
As some vehicles will not be compatible to run on E10, supplies of E5 petrol will be maintained in the super petrol grade form of premium unleaded fuels. This means fuels such as Shell’s V-Power petrol and BP’s Ultimate fuel will still only have up to five percent ethanol.
E10 fuel will become the standard fuel type for petrol cars only – It is not suitable for diesel cars.
Diesel – B7 fuel, will still be available at fuel stations for motorists to fill up their diesel vehicles.
Putting E10 fuel in a non-compatible car may make the car difficult to start, and may cause pre-detonation (knocking) in older engines.
If you use E10 fuel in a non-compatible car over a long period of time, it may well cause lasting damage to the engine. Bioethanol has corrosive properties and according to the Department for Transport (DfT) potential issues include:
- Blocked fuel filters
- Damaged fuel pumps
- Degradation to flexible fuel hoses
- Corroded carburetors
E10 compatible cars: Can you use E5 fuel or mix E10 and E5 fuels?
If your vehicle is E10 compatible, there’s no reason that you can’t mix the E5 and E10 grades of petrol.
It’s perfectly safe to mix E5 fuel and E10 fuels in the same tank or fill up with E5 if E10 is not available.
To check if your vehicle is e10 compatible, ahead of the introduction of e10 petrol this Autumn, the Government has launched a new online tool.
The new online tool for checking if your car, van, motorcycle or moped will be compatible with the new E10 fuel can be found at Check if your vehicle can run on E10 petrol - GOV.UK (www.gov.uk)
E10 fuel will not affect whether you are able to drive in, or have to pay to enter, a clean air zone (CAZ), low emission zone (LEZ) or ultra-low emission zone (ULEZ); this is determined by your car’s Euro emissions standard and not by the fuel used.
