What is E10? Government changes to petrol fuel specifications


From September 2021, the UK government will be implementing new standardisation rules to petrol with the introduction of E10 across the country.

E10 is a biofuel that consists of 90% regular unleaded petrol and 10% ethanol, it is more efficient than current petrol standards (95 octane) that are only 5% ethanol, more commonly known as E5.

As we see more electric and hybrid vehicles, E10 will also contribute to significantly cut (CO2) carbon emissions and will align the UK with other European countries such as France, Belgium, Germany and Finland where E10 has already been rolled out. 

Materials to produce E10 will be sourced and manufactured from within the UK and will be a step closer to reaching the government's aim of zero emissions by 2050.

Petrol stations will soon start to label its pumps with either E10 or E5 so drivers can easily identify which to use before refuelling.

So what vehicles are compatible with E10?

All new vehicles manufactured from 2011 can run on E10 along with a number of older cars from as late as the 1990’s, that have been approved to use the new petrol. 

It is encouraged that if your vehicle is compatible with E10 then this should be the preferred choice at petrol stations once available however, mixing E10 with and E5 is perfectly safe. 

What does this mean for FuelCare? 

With the production and roll out of E10, petrol will now contain more water, which will increase the need for fuel biocide like FuelClear™ MB15

FuelClear™ MB15 is equally effective in systems containing both fuel and water but unlike other fuel treatment biocides, the active ingredients in FuelClear™ MB15 are not deactivated by water.
