Here Is What Happens Stop. Engine off. Keep it like that — no second on, no shifting it at all. Petrol in a diesel that has not been run is normally a simple drain plus a flush, done right where the car sits, and what happens in the coming few minutes decides that far more than anything else. Here is the sequence of things from now, wherever you're around Royley. ## Motor off: minute one with petrol in a diesel Work through the following first, in this sequence. - The keys out of your ignition. Switching your ignition on can be enough to prime the system, while priming pulls petrol out of the tank towards the parts it damages. Keep the car off altogether. - Topping up with diesel sounds like it thins the problem. It does not: nothing gets out, and your tank just carries more of the same. - Visibility comes first near moving traffic: switch the hazard lights on, and only then deal with everything else. - The staff will generally help you push it clear of the petrol pump. Let them, and move it by hand — not on your engine, even for a couple of yards. - The first question you will be asked is which fuel went in and about how much — and your receipt shows both. Keep it. Noticed on the move? Get off at the next junction if you are on the A627(M), under a mile from Royley, and stop somewhere sensible — not at the services further on. Stage one starts after that. ## Each Royley fuel drain starts here: has the motor run? Everything after this point depends on one answer. If it has not once been started: - All the petrol sits in the tank, and just there. - The work is a simple drain and a flush, usually done where your car stands. - Step one counts for exactly this reason: it's the best spot to be in. Run at all, even for a second: - The lines and the filter already carry petrol pulled out of the tank. - On a longer run it has got to your high-pressure pump as well as the injectors. - Miles is what turns it into a larger job: flushed lines, a filter seen to, and at times more than that. Why the line falls there: diesel protects the high-pressure pump as well as the injectors as it flows through them, and petrol does not. In that tank, left alone, petrol harms nothing. Pump the petrol, though, and it wears the very parts doing the moving. ## Calling about petrol in a diesel from Royley: what to have prepared A little preparation is the difference between a technician that finds you and a van that goes round. - Where you have stopped. A postcode starting OL2 5 is the best start. - Name the street — Royley Crescent or wherever you have pulled up — or the car park. - What a car park serves is the quickest way to find it, and so say the landmark — like the one outside Lidl. - Tell us what your car is — make, model — and confirm it is diesel. - Say which went in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Royley. - About how much — in litres from your receipt, or by how long the nozzle was in. - The mileage it covered, and how heavily, if it has run at all. - Hire or company car? Some contracts want the owner's go-ahead for this work, and sorting it before we get there is quicker than after. Then ring 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick too. ## Waiting for a fuel drain in Royley: what to do In the wait, the damage comes from well-meant help — which is why these count. - Stay with the car if it's safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - No one — however helpful — starts it, whether to see if it runs or to move the car a short way. - None of that takes that petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives. - A home-made drain misses your fuel that has already gone beyond that tank, and siphoning petrol by the road is dangerous besides. - Not for your radio, not for the windows: your ignition remains off. ## When our van arrives: your fuel drain, step by step - Three queries. What went in, how much, and whether it has run. Those answers set this job, which is why our price comes after them and not before. - Clearing it is how the mixture gets taken from the tank. - Petrol that has moved beyond your tank travels in your lines if it ran, and your lines are flushed to shift it. - Where the car has a workable filter, it's replaced; otherwise, cleared. - The system is primed with clean diesel. - Our engineers start the car only after new diesel has gone in and primed your system, then confirm that it is running smoothly. Only when it's running on fresh diesel do we go. Lasting damage is very unusual if it has been spotted quickly, so your car can go straight back to normal use. ## Royley, after the fuel drain: back on the road - Drive normally. There's nothing special to do once it's been started on fresh fuel. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your cue to stop and ring us a second time. - Keep the paperwork. A hire company, a fleet manager or an insurer may ask what was carried out. - Next time, go by the petrol pump's label instead of the colour of its handle. ## About Royley itself Royley is a suburban area in Greater Manchester, situated near the river and characterised by semi-detached housing.
