Tom Wood, spokesperson for Car and Classic said additives were “recommended” to help “avoid damage” around key car parts. He said additives were key to “break down any water in the fuel” which can help reduce the effects of damage to steel tanks and the vehicle’s engine.
However, he has still assured drivers should “not panic” about the update despite drivers showing massive concern over the changes.
Mr Wood said: “E10 fuel has been available in Europe for a while and now it’s confirmed that the pumps will have E10-grade fuel from September.
“Some have already started stocking the blend.
“So, what is E10-grade fuel? Well, in a nutshell, regular petrol will now carry a 10 percent blend of bioethanol; the alcohol element that is made from low-grade grains and sugars.

“If you do have to use E10 in your classic in an emergency (and frankly we recommend with E5 too) to use a fuel additive to help break down any water in the fuel that the higher ethanols can attract.
“Especially in classic car steel tanks and to avoid damage to your engine.”
Experts at Hagerty Insurance have urged owners to consider a range of fuel additives when topping up their car with E10 fuel.
The Federation of British Historic Vehicles Clubs recommends lead replacement additives such as Castrol’s Classic Valvemaster which can help prevent corrosion.
Hagerty said owners of modern classics should consider Millers Ethanol Protection Additive or Lucas Oil Ethanol Fuel Conditioner.
But, they urge drivers should check with their vehicle manufacturer or an owners club to find the best solution for their vehicle.
The RAC has previously estimated at least 600,000 cars will be incompatible with the new fuel.
As a general rule, cars which were built before 2002 were likely to be the most affected with all vehicles built after 2011 set to be compliant with the new fuel.
The RAC warned the dangers of putting E10 in an incompatible vehicle “depends on the vehicle”.
However, according to Hagerty, tests from the Department for Transport identified a range of possible issues.
These included degradation to duel hoses, blocked fuel filters and corroded carburettors.
