E10 petrol is a type of unleaded fuel that contains up to 10% renewable ethanol, which is a biofuel made from fermenting corn and sugarcane. This fuel is considered more environmentally friendly than regular petrol because it reduces carbon dioxide (CO2) emissions associated with petrol vehicles and helps tackle climate change. E10 petrol has already been rolled out across many European countries, including the UK, and is widely available at petrol stations. However, it is important to note that not all vehicles are compatible with E10 petrol. Some older vehicles and certain models may not be able to use this fuel, and using it in incompatible vehicles can cause damage to the engine. Therefore, it is recommended to check the vehicle manual or use an online compatibility checker before using E10 petrol.
