Statement from https://www.gov.uk/guidance/e10-petrol-explained
‘During summer 2021, the standard (95 octane) petrol grade in Great Britain will become E10. In Northern Ireland, this will happen in early 2022.
The change in fuel applies to petrol only. Diesel fuel will not be changing.
Almost all (95%) petrol-powered vehicles on the road today can use E10 petrol and all cars built since 2011 are compatible.
If your petrol vehicle or equipment is not compatible with E10 fuel, you will still be able to use E5 by purchasing the ‘super’ grade (97+ octane) petrol from most filling stations.Petrol pumps will clearly label petrol as either E10 or E5.'
Almost all petrol powered vehicles in the road today can use E10, this includes all Hyundai models produced since 2005, with a number of our other models manufactured since the late 1990’s.
To support the reduction of CO2 associated with petrol vehicles and tackle climate change.
Using E10 petrol may slightly reduce your fuel economy and it is possible that you may see around a 1% reduction.
Your vehicle warranty will not be affected by the use of E10, this petrol is approved for use by Hyundai Motor Company. However, your Hyundai manufacture warranty will not cover failures or faults due to operation on fuels with an Ethanol content greater than 10% or from the use of fuels which do not meet the required standards.
If you believe your vehicle may be affected by this change, please contact your local Hyundai Dealer who can clarify the situation for you and advise on any current offers they have available across both New and Used Hyundai Vehicles including any relevant scrappage schemes.
