The Federation of British Historic Vehicle Clubs has released a statement on the introduction of E10 petrol in the UK.

E10 petrol contains up to 10% ethanol. Ethanol has been shown to cause damage to various part of our old cars, including degradation of rubber and plastic components, such as hoses, seals, fuel lines and filters. It also absorbs water from the atmosphere, potentially leading to condensation and corrosion in fuel tanks, lines and other metal components.
