E10 Fuel, What you need to know

What is E10 Fuel?

In short, E10 refers to 10% Bio-Ethanol content in 95-Ron fuel, it’s been 5% (E5) for some time now and will be changing in all regular petrol across the UK throughout the summer.

Why is this happening?

It will help drop the C02 Emissions of the UK by some 750,000 tonnes according to The Bio-ethanol is created from renewable sources, mainly through sugar fermentation from the likes of corn, maize and wheat crops.

Do I need to do anything about it?

Well, for most people the answer is probably no. Around 95% of cars are compatible with E10.  If you drive a Ford car built after 1992, all but one car is compatible with the new fuel – the Mondeo 1.8 Sci, built between 2003-2007.

If you drive a vehicle other than a Ford and it’s older than 2011, we’d strongly suggest using the gov websites checker, here

If you drive a classic car, your vehicle may not be compatible with E10. Some filling stations will continue to sell high-octane fuel (97 Ron+) which is typically E5, however always check the nozzle before filling.  Some scooters, mopeds and bikes, particularly those less than 50CC may not be compatible. The same applies to some boats, mowers and other garden machinery. For those, please check with the manufacturer.

What are the downsides?

Fuel economy can be slightly adversely affected with E10, (officially reported to be 1%) however the greater risk is to classic vehicles whereby the ethanol can degrade rubber seals or fibreglass fuel tanks over time.  

What if I fill up by mistake?

Don’t panic, this shouldn’t pose a real risk for one tank (unless you are storing the car for a period) simply keep topping up with E5 to dilute the E10 down and this is safe.

Can I mix E10 and E5 fuel?


Does Cuff Miller seller E5 Petrol?

Cuff Miller has now swotcjed entirely to E10 Petrol.

I drive a classic but want to fill up at Cuffs, can I add anything to my fuel?

Yes, it is possible to add fuel stabiliser to E10 and E5 fuel which should help fight corrosion, although we have not yet evaluated any ourselves. We would still not recommend classic vehicles sit with fuel in the tank for any length of time if possible.

How do I check my vehicle is ok with E10?
