E10 fuel is a new petrol made up of 10 percent bioethanol compared to the current 5 percent fuel. Initial estimates suggest the new petrol could reduce CO2 emissions by 750,000 tonnes per year, the equivalent of removing 350,000 cars off the streets.
When will E10 be introduced?
Last week the Government confirmed new E10 fuel would be introduced at petrol stations from September 2021.
This follows on from a consultation by the Department for Transport which had always planned to introduce the fuel this year.
The Petrol Retailers Association confirmed earlier this year they were expecting a late 2021 launch.
Can all cars use the new fuel?
The Department for Transport has warned around 95 percent of cars are approved for E10 fuel use.
Cars manufactured since 2011 are likely to be compatible with E10 fuel as long as they are approved by manufacturers,
However, classic vehicles and specific cars from the early 2000s may not be able to run the new fuel.
Hagerty Insurance has warned ethanol is hygroscopic meaning it absorbs more water from the atmosphere and pulls this into the fuel tank.

This can lead to extra condensation in fuel tanks which is something not recommended for classic vehicles.
Tests from the Department for Transport (DfT) identified degradation to fuel hoses and seals as an issue.
They also warned using the new field could damage fuel pumps, corrode carburettors and lead to blocked injectors.
The DfT has urged drivers to check whether the car is approved to use E10 fuel using a compatibility checker.
Will E5 still be available for older cars?
The Department for Transport has urged drivers who have vehicles that are not compatible with E120 fuel to continue using E5 fuel.
This will become the super grade petrol from September and will be available at petrol stations which sell two grades of petrol.
However, the DfT’s Introducing E10 report suggested E5 fuel will only be kept as the protection grade for an initial five years.
After this date, the regulation will be reviewed to decide whether the protection should be extended.
How much will it cost?
The AA has warned the switch could add around 1.6 percent to all drivers’ fuel costs because it is less efficient.
This means drivers will need to buy more fuel for each mile they travel which will see costs rise.
The Telegraph has also warned boosting E5 to the super grade could cost drivers an extra £100 per year.
