Gary Wilson, head of the Historic and Classic Vehicle Alliance (HCVA) has warned “time will tell” if vehicles have been affected in any way by the new petrol compound. He warned classic car owners were likely to know the true extent of E10’s effects by “spring” in a blow to motorists concerned for their vehicle’s safety.
“Obviously, there is more moisture in the air.
“Possibly there will be times over Christmas where we don’t use our cars as much.
“Most definitely, without a shadow of a doubt, give it six months to a year we are going to see some bigger problems coming along.
“Most problems can be rectified in a service but some of them won’t be.
“I imagine some of them will probably kill a car cost-wise.”
North West Workshop, YouTube creators specialising in car modifications and mechanics, also warned cars could become damaged just after winter.
This was because cars will be left doing nothing which could cause “corrosive water” to build up in the fuel tank.
They said: “Ethanol, if unused for a long period of time, can absorb corrosive water in the fuel tank.
“This means it could damage a car that is not used for a long period of time that contains that fuel.
“Such as a car that’s going to be stored over winter months and only used in the summer.”
Motoring experts at insurance firm Hagerty have warned incompatible vehicles could be damaged if drivers use E10 fuel incorrectly.
They warned ethanol can lead to “condensation in fuel tanks, fuel lines and carburettors”.
In some situations, this can also lead to “corrosion in brass, copper, lead, tin and zinc”.
Tests from the Department for Transport identified a range of issues such as degradation of fuel hoses and blocked fuel filters.
Cars may also suffer damaged fuel pumps, corroded carburettors and blocked injectors.
