Answered by Rambo S, Wrong Fuel Expert at Fuel Fixer International. ## What "local" actually means here It means the number is answered by the people who send technicians to Durham, and that coverage of DH1, DH6, DH7 and the surrounding districts is a dispatch area rather than a marketing claim.

The longer answer Diesel lubricates the high-pressure pump as it passes through. Petrol is a solvent and removes that film, so a diesel pump run on petrol can wear rapidly and shed metal particles downstream into the injectors. Diesel in a petrol engine is messier than it is destructive — heavy smoke, misfiring, stalling — because diesel will not ignite properly from a spark. Both need draining. Only one of them gets dramatically worse with every mile. **Short answer**: Yes, considerably. Petrol strips the lubrication a diesel high-pressure pump depends on; diesel in a petrol engine mostl **Cost**: From just £89 misfuel callout fee, quoted before we travel **Where**: Durham and DH1, DH6, DH7 and the surrounding districts **Hours**: 24 hours, every day ## What actually happens inside the fuel system Fuel leaves the tank through the lift pump, passes the filter, reaches the high-pressure pump and then the injectors. Petrol in a diesel system strips the lubrication that high-pressure pump depends on, and metal shed by the pump travels downstream into the injectors. That sequence is the whole story: cost depends on whether the engine ran, and for how long, not on how many litres went in. Durham sits at the centre of a wide rural catchment. Once you are out towards Consett, Crook or the coast, the nearest dealer is a long way off and a mobile drain is comfortably the faster option. ## What to do now Do not start it — that is the whole thing Everything else on this list is detail.
