Petrol in Diesel help across Northamptonshire
Our technicians are out across Northamptonshire around the clock, covering Northampton, Kettering and Corby and everywhere in between.
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 A43, A45 and M1 and the wider East Midlands road network well, so roadside call-outs are reached fast.

Any amount is worth draining. Modern common-rail diesels are far less tolerant than older engines.
