Petrol in Diesel help across Buckinghamshire
From High Wycombe, Aylesbury and Amersham to the smallest village, our Buckinghamshire technicians reach most call-outs within the hour.
Diesel engines rely on the fuel itself to lubricate the high-pressure pump and injectors. Petrol is a solvent, so even a few litres strips that lubrication and can grind metal parts together within minutes of running. Caught early, it is a straightforward drain and flush; driven on, it can mean a new pump, injectors and fuel lines.
We know the M40, M1 and A41 and the wider Home Counties road network well, so roadside call-outs are reached fast.
