The introduction of E10 fuel has been big news on the motoring scene since it came into effect last month, but what is E10 petrol, how will it affect you and your car, and is there any concerns about storing your vehicle when using this new fuel option? Here we answer all those important questions…

What is E10 fuel?

E10 fuel has now replaced all standard, unleaded and main grade petrol at pumps up and down the country. It’s one of the latest mandates enforced on the motoring sector by the government to make the industry more environmentally friendly.

E10 is a biofuel that consists of 90% regular unleaded petrol and 10% renewable, carbon neutral ethanol, compared to standard unleaded which uses just 5% renewable ethanol. This slight increase of renewable ethanol is hoped to dramatically reduce air pollution and CO2 emissions. 

The introduction of E10 is a part of the government’s bigger plan to lower greenhouse gas emissions to net zero by 2050.

Can E10 be used in all vehicles?

The blanket move to E10 across our nation’s forecourts has caused much controversy, mainly because not every petrol-powered vehicle can take E10 fuel.

Sources suggest that up to 95% of petrol-powered vehicles on the road today are compatible with E10, this includes all cars constructed post-2011. This however still leaves as many as 600,000 vehicles unable to use the new fuel.

Older cars, including classic models, can develop significant problems as a result of E10 usage. The higher concentration of ethanol can cause fuel tank condensation, corrosion and blockages, damage, and other degradation.

To check the compatibility of your car, van, motorcycle or moped, please use the government’s E10 online checker.

Could E10 affect how my car is stored?

For vehicles manufactured before 1996, there’s additional concerns about E10 usage in storage, especially if the vehicle doesn’t have a catalytic converter.

It is recommended that you use a lead replacement additive to stabilise the ethanol and prevent corrosion before storing your vehicle. Another option is to have your fuel tank fully drained or filled and sealed before storage.
