Petrol in a Diesel Car Ferryhill canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/ferryhill-durham/ location: Ferryhill county: Durham latitude: 54.689050 longitude: -1.556870 service: Petrol in a Diesel Car updated: 2026-10-21 --- # Petrol in a Diesel Car in Ferryhill: What Happens Now Stop, then keep your engine off — not on, and not for a second to shift it. Cleared and cleaned, just where it is: that's usually all an unrun diesel with petrol in it takes. Whether it stays that straightforward depends on the minutes ahead far more than on anything else. What follows is the sequence from here, anywhere in Ferryhill you are. ## Motor off: minute one with petrol in a diesel Go through the following in sequence, before you do anything else. - Take your keys out. Even the ignition on its own can prime the system, drawing petrol out of your tank to exactly the components it harms, and so leave the vehicle off completely. - Topping up with diesel sounds like it dilutes the issue. It doesn't: nothing comes out, and the tank just holds more of the same. - Close to moving traffic? Then your hazards go on before everything else, so the vehicle is simple to spot. - By hand, never on the motor: that is how it comes off the pump. Get the forecourt attendants to help you roll, whatever the mileage. - The first thing you will be asked is which fuel went in and roughly how much — and the receipt says both. Hold on to it. Realised on the move? Get off at the next exit if you are on the A1(M), under 3 miles from Ferryhill, and stop somewhere safe — not at the services further on. Stage one starts after that. ## Every Ferryhill fuel drain starts here: has the motor run? One answer is what everything after this point rests on. Not run, not even once: - Nowhere but that tank: that's where the petrol yet is. - Draining and flushing, on the spot, is normally all of that. - Step one counts for exactly this reason: it is the best position to be in. Run at all, however briefly: - Petrol has been pulled out of your tank, through the fuel filter and into the fuel lines. - A bigger run takes it all the way to your high-pressure pump and the fuel injectors. - Distance is what makes it a larger job: the lines flushed, a filter seen to, and at times more than that. Diesel keeps the high-pressure pump and your injectors lubricated as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. A tank of petrol, left alone, hurts nothing. Petrol being pumped is wearing the components that shift the vehicle. ## Calling about petrol in a diesel from Ferryhill: what to have prepared A little preparation is the difference between a technician that finds you and a van that circles. - Where you are. A postcode beginning DL17 8 is the best start. - A road name helps: Market Street, say, or whatever street you have stopped in. A car park does the trick too. - What a car park serves is the easiest way to find it, and so say the landmark — such as the one outside Asda. - That it is a diesel, plus the make and model of the car. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Ferryhill page. - How much. Litres from your receipt, or how long the nozzle was in. - Whether it's run. Then if it has, how far plus how hard. - Settle who has your car ahead of when our technicians turn up: some hire or company contracts want the owner to authorise this work, and doing it quicker first. Ring 0333 366 0103 then. Writing to works as well if it can wait, with the vehicle parked at home, going nowhere. ## Ferryhill fuel drain on its way? While you wait Help, however well meant, is the thing that does the harm whilst you wait. So hold to these. - Safety before the car. If it has stopped somewhere dangerous, get yourself clear of the traffic then wait away from it. If it is safe where it sits, wait with it. - A kind passer-by does not start it. Nor does anybody checking it still does the trick, or rolling it a few yards. - Additives stay in the boot. Injector cleaner and two-stroke oil take none of the petrol out a second time. - Clearing it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank remains put regardless. - The ignition remains off. Even for your radio or the windows. ## When the van arrives: the fuel drain, step by step - First, three questions: which fuel got in, the quantity, and has it run? Those replies shape this job, and so our price follows them. - Out of your tank comes the polluted mix: the tank is drained. - Petrol that has shifted beyond your tank travels in the lines if it ran, and the lines are purged to shift it. - Then the filter: changed where there's a serviceable one, cleared where there's not. - Priming follows after fresh diesel is in. - The first start on clean diesel. Once priming is done, the motor is started and our engineers check that it runs correctly. Our technicians wait until it is running on clean diesel. It is very rare for a vehicle spotted early to be left with long-term damage, and normal driving resumes right away. ## Once your fuel drain is done: driving in Ferryhill once more - Drive normally. There's nothing unusual to do once it's been started on fresh fuel. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle means pull over then call us back. - Keep your documents. A hire company, a fleet manager or an insurer may ask what was done. - The handle's colour isn't the thing to go by next time — the label on the petrol pump is. ## About Ferryhill, briefly Ferryhill is a town in County Durham, situated inland at an elevation of 163 metres, approximately 6 miles from the city of Durham.
