Unleaded in Diesel help across Surrey
Our technicians are out across Surrey around the clock, covering Staines, Leatherhead and Farnham and everywhere in between.
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.
We know the M3, M23 and A3 and the wider South East road network well, so roadside call-outs are reached fast.
