Worried about Ethanol & E10 Petrol?

Today’s fuels pose more danger to small engines, with ethanol blends becoming increasingly common. E10 petrol has become the standard in the UK. This means petrol now contains up to 10% ethanol.

STA-BIL protects against ethanol damage. The solution works safely and effectively in all petrol blends, including ethanol-blended fuel up to E85. This includes the new government standard E10 petrol.
