Experts at H&H Classics warn drivers will need to top-up with the more expensive E5 fuel if their vehicle is incompatible with the new E10 petrol. H&H says “most classic cars” will be affected by the new E10 changes.
They have warned drivers should be using E5 fuel even if rates have dramatically increased over the past week.
Damien Jones, Head of Sales at H&H Classics said: “Most classic cars are indeed incompatible with the new E10 petrol.
“However, you can still buy E5 petrol, albeit it in a more expensive, higher octane guise as Super Unleaded.
“There are no plans at present to stop selling Super Unleaded which most petrol stations stock.

Prices have increased by just over £5 across the rest of the UK with some areas such as Scotland seeing lower £4.70 rises.
Before the launch of E10, the AA warned prices could even rise by up to £15 for classic car owners.
They predicted E5 rates could rise from 135.4p per litre to 163.9p once E5 was moved to the Super Unleaded pump.
This would see the cost of filling a 55-litre tank rise from £74.47 to £90.15.
They said: “The Government and fuel providers have had a long time to smoothly roll this change out and they seem to have done so without much drama for most motorists.
“However, for the unlucky 600,000 plus drivers who now have to pay up to 10 percent more for their fuel, depending where in the UK they refuel, this is potentially just the beginning of their cost increases”.
E10 fuel was launched last week in a bid to cut CO2 emissions on the road.
The new fuel is set to cut CO2 emissions by around 750,000 tonnes which is the equivalent of removing 350,000 cars from the road.
