A new E10 petrol which will soon be introduced will not be compatible with certain cars.
The new unleaded petrol, which is set to come into effect in September in a bid to reduce carbon emissions, is already being rolled out on certain forecourts.
But certain cars that are older than 2011 may be at risk of damage or even voiding the owner's insurance, reports Birmingham Live.

This change is excepted to affect almost a million cars across the country and you can double check if your car is affected.
There are a number of ways that owners can check if their cars are affected by the change.
One of the ways is by using the Govenment's E10 checker where you put in your licence plate which tells you if your vehicle is not compatible.
However, according to the RAC, there will be makes of cars that will not be compatible with the E10 petrol and users should be made aware of them

Malcolm McKay, spokesperson for the Historic and Classic Vehicle Association, warned it was not all bad news.
He suggested E5 fuel would likely be available “for a while” due to the popularity for higher octane fuels.
He said: "It certainly hasn’t had as much publicity as the change from leaded to unleaded fuel.
"It's another of those things, I think that the classic car movement to an extent have been scared to make too much of a fuss.
"We’ve just got to find a way around it.
"E5 is still going to be available for a while but it's more a case of the Government has said it can be available.
"It’s then up to the oil companies and the suppliers to decide whether there is enough demand.
"But as it’s the higher octane fuel and there's quite a lot of younger cars that run a lot better and more efficiently on the higher octane fuel I think we will see it around for quite a long time.
