Unleaded in Diesel help across Flintshire
We're on call across Flintshire every day of the year, with regular jobs in Connah's Quay, Holywell and Deeside.
Standard unleaded (E10) and super unleaded are both petrol, and either one will damage a diesel fuel system if it is circulated. Ethanol in E10 also attracts moisture, which adds to the risk of corrosion if the mix is left in the tank.
Breakdowns on the A548, A541 and A55 are reached quickly, and we attend lay-bys, services and car parks as well as forecourts.
