What happens if you put E10 fuel in a non-compatible vehicle?

As from 2011, all petrol vehicles must be able to take E10 – a type of petrol with 10 percent ethanol. Some vehicles built before 2011 can take E10, but it’s best to check your vehicle handbook to be sure, or visit the E10 compatibility guide.

Even if your petrol vehicle isn’t compatible with E10, it will still run as normal, but there is a risk of long term engine damage due to the corrosive nature of bioethanol.

If you have accidentally fueled your petrol vehicle with E10, it’s best to drain the fuel tank, flush the entire system and refuel with E5 as soon as possible.
