Signs have started appearing at petrol stations warning drivers of a change to petrol that could impact their vehicles.
By the end of summer, a new E10 blend of petrol will be sold in the UK as a replacement for the standard (95 octane) Scots are used to.
However, some cars will not be compatible with the new unleaded fuel, meaning all drivers are being urged to check the new advice to avoid a disastrous trip to the garage.
According to the Government's website, only cars that were made after 2011 can use the new fuel blend that will be on display from September 1.
The site also said that pumps for E5 and E10 will be "clearly labelled" and there will be no changes to diesel.
One of the signs on display in a Sainsbury's forecourt reads: "Unleaded petrol changing on the 1st of September from £5 to E10.
"E10 will be suitable for most vehicles, please check before use."
However, although 95 per cent of petrol engines can use E10, some drivers will have to continue using E5, which can be bought as super-grade (97+ octane) fuel at most filling stations.
Pumps for E5 and E10 will be "clearly labelled" and there will be no changes to diesel, the Government's website added.
E10 petrol contains up to 10 per cent renewable ethanol, which will help reduce carbon dioxide emissions that come from petrol vehicles and help tackle climate change.
Petrol in the UK currently contains up to five per cent renewable ethanol (known as E5).
E10 petrol is already widely used across Europe, America and Australia.
By blending petrol with up to 10 per cent renewable ethanol, less fossil fuel is needed, helping to reduce carbon emissions and meet climate change targets.
Offering E10 petrol on forecourts in the UK could cut transport emissions by 750,000 tons a year. That is the equivalent of taking 350,000 cars off the road or all the cars in North Yorkshire.
If your vehicle is compatible with E10 petrol, there’s no reason why you can’t mix the two grades of petrol (E5 97+ and E10 95+). It’s perfectly safe to mix them in the same tank or fill up with E5 if E10 is not available.
People can find out if their car is compatible with the new blend by using the Government's official vehicle checker at E10 vehicle checker.
The following vehicles, however, may not be compatible with E10 petrol: Classic, cherished and older vehicles; some specific models, particularly those from the early 2000s; some mopeds, particularly those with an engine size of 50cc or under; and boats, lawnmowers and chainsaws.
If you put E10 in your non-compatible vehicle by mistake, it "should not be a major problem" if you only do it once - but make sure you pick the correct fuel the next time, the website explains.
