You might have found yourself reading about the new E10 Petrol that is becoming the standard grade in Petrol forecourts shortly in the UK. If you are finding yourself wondering what can be used, please be assured that Regular unleaded 98, 95, 95 E5 or E10 petrol can be used in most petrol garden machinery products; however do not use any petrol containing more than 10% ethanol. This will cause corrosion damage to fuel system components.
What is E10?
E10 is a fuel made of 10% Ethanol (Hence the name E10) and 90% regular unleaded petrol. Ethanol is an alcohol that can be made from plants, including wheat and sugar beet. Current petrol used to contain 5% Ethanol with the other 95% being unleaded petrol.
The reason for the change is that the UK government argues that the use of E10 will have environmental impacts with the reduction of CO₂ emissions. They state that by doubling the renewable component (ethanol) in fuel then a reduction of 750,000 tonnes of CO₂ emissions, which could be around the same as taking 350,000 cars off of the road.
Are there any problems?
Ethanol is also a hygroscopic – which means it absorbs water from the atmosphere, leading to condensation in fuel tanks if the machine remains unused for long periods of time.
Information issued by the Federation of British Historic Vehicle Clubs confirms that the increased acidity, conductivity and chloride content of ethanol in E10 can cause corrosion and tarnishing of metal components (such as carburettors & fuel pumps), these problems occur when petrol is left in the machine over an extended period of time, so there is no need to drain your fuel immediately but to negate any problems with using older aged fuel you can use our fuel stabiliser that is for sale here >
