Next Steps canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/cruwys-morchard-devon/ location: Cruwys Morchard county: Devon latitude: 50.897600 longitude: -3.603410 service: Petrol in a Diesel Car updated: 2026-10-17 --- # Petrol in a Diesel Car in Cruwys Morchard: What Happens Now Stop. Engine off. Keep it like that — no second on, no shifting it at all. Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever the car has stopped — and nothing settles that as much as these next few minutes do. From now on, in order, wherever you are in Cruwys Morchard: ## Petrol in a diesel, engine off — the first minute In this order, and before everything else: - The keys out of the ignition. Turning the ignition on can be enough to prime your fuel system, and priming draws petrol out of the tank towards the parts it damages. Leave it off altogether. - No diesel on top. More fuel in takes away none of that petrol — it only makes you with extra of the same mixture. - Get your car easy to see before anything else — hazards on — if there's traffic going past anywhere close to you. - The attendants will generally help you roll it clear of the petrol pump. Ask, then move it by hand — not under the motor, even for a few yards. - The first question we will ask is which fuel went in and roughly how much — and your receipt says both. Keep it. If you were still driving when you noticed, pull over somewhere safe rather than pushing on for the services — on the M5, under 10 miles from Cruwys Morchard, that means the next junction. Step one comes next. ## The fork in each Cruwys Morchard fuel drain: has it run yet? Everything after this stage depends on one answer. If it has never been started: - All the petrol remains inside your tank, and just there. - Where the car stands is normally where the work happens: a drain, then a flush. - This is the best case — which is the whole point of stage one. If your engine has run, even for a moment: - Petrol has been drawn out of the tank, through your filter and into your lines. - On a bigger run it has got to the high-pressure pump as well as the fuel injectors. - Miles is what makes it a larger job: the lines flushed, a filter seen to, and at times further work. Petrol doesn't lubricate. Diesel does, protecting the pump and injectors as it flows through, which is why the line sits where it does. A tank of petrol, left alone, hurts nothing. Pump the petrol, though, and it grinds down the very parts doing the moving. ## Cruwys Morchard, petrol in a diesel: have these ready before you call Get ready a little, and the technician finds you instead of circling. - EX16 8 and the rest of the postcode is the ideal way to begin telling us where you are. - Wherever you have parked, the road's name is useful — whether that's Northcote Lane or somewhere else — and so does the name of a car park. - Describe a car park by what it serves — the one at Morrisons, for instance — and it's far quicker to find. - Tell us what the car is — make, model — and confirm it is diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Cruwys Morchard page. - Roughly how much — in litres from your receipt, or by how long the nozzle stayed in. - The distance it did, and how hard, if it ran at all. - Sort who has the car before we turn up: some hire and company contracts want the owner to approve the work, and doing it faster first. Ring 0333 366 0103 once you have got that ready — or, if your car is at home, going nowhere, use . ## While you wait for a fuel drain around Cruwys Morchard The wait is where well-intended help does the harm. Stick to these. - Stay with your car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - Nobody — however kind — starts it, whether to see if it runs or to move your car a short way. - Additives stay in your boot. Injector cleaner and two-stroke oil draw none of the petrol out once more. - Siphoning petrol into a can at the kerbside is risky — and it still leaves whatever fuel has already gone beyond that tank. Do not drain the car yourself. - Not for the radio, not for the windows: the ignition stays off. ## When our van gets there: your fuel drain, step by step - Fuel, quantity, whether it has run: the replies decide the job, and that is why we give a quote after them instead of before. - That tank is emptied. The polluted mix comes out of your tank. - If it ran, your lines are holding petrol that has moved beyond your tank — so they are rinsed. - Where your car has a workable filter, it is swapped; if not, cleared. - Fresh diesel in, and the system primed. - Starting up. Once the system is primed with new diesel, our technicians start the car and make sure it runs correctly. The vehicle has clean diesel running through it before our engineers leave. When it has been spotted quickly, permanent damage is very unusual, and the vehicle returns to normal driving right away. ## Back on the road in Cruwys Morchard after your fuel drain - Drive normally. There is nothing unusual to do after it has been started on fresh fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over then ring us back. - Hold on to the documents. A hire firm, a fleet manager or an insurer may ask what was carried out. - Check the label on the pump next time, not the colour of the handle. ## About Cruwys Morchard and where it is Cruwys Morchard is a small hamlet in inland Devon, situated at an elevation of 222 metres, approximately 12.5 miles from Exeter.
