Motor off. Leave it like that — no moment on, no moving it anywhere. Has not been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever your car has stopped — and no other factor settles that as much as the next few minutes do. Here is the sequence of things from here, anywhere you are around Downall Green. ## Minute one: petrol in a diesel, motor off Do these before anything else, in this sequence. - Priming the system draws petrol from the tank towards the components it damages, and switching the ignition on can be enough to do that. So your keys get taken out, and your ignition stays off completely. - Do not top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture. - Near moving traffic? Then your hazards go on before anything else, and so the vehicle is easy to see. - However short the way, starting it to move it is the thing to avoid. On a forecourt, roll the car clear of the pump by hand instead, then ask the staff to lend a hand. - The first thing you will be asked is which fuel you put in and roughly how much — and the till receipt says both. Keep it. If you were still driving when you realised, stop somewhere sensible rather than pushing on for the services — on the Bryn Spur, under a mile from Downall Green, that means the next junction. Stage one follows. ## Every Downall Green fuel drain starts here: has the engine run? One answer is what everything after this point rests on. If the motor hasn't run at all: - Nowhere but your tank: that is where that petrol yet is. - Usually it's drained and rinsed right where the vehicle stands. - No spot is better, and it is why the first step matters so much. Run at all, however briefly: - Petrol has been pulled from your tank, through the fuel filter then into your lines. - On a bigger run it has reached the high-pressure fuel pump and the fuel injectors. - Mileage is what turns it into a larger job: the lines flushed, a filter seen to, and at times further work. That line falls there since diesel lubricates the high-pressure fuel pump and the injectors on its way through them — and petrol does not. Nothing is harmed by petrol that's only waiting in a tank. Move that petrol, though, and it grinds down the very parts doing the moving. ## Before you call about petrol in a diesel around Downall Green: what we need Whether the technician goes round or finds you comes down to a little planning. - Where you are. A postcode starting WN4 0 is the ideal start. - The street or the car park. A road name is a help — Elm Avenue, or wherever you have pulled up. - Car parks are located more easily by what they serve: say the one at Londis, and it's easy. - Make and model of the car, and the fact it's a diesel. - What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for Downall Green, and so tell us which. - About how much — in litres from the receipt, or by how long the nozzle was in. - The miles it did, and how hard, if it has run at all. - The owner may have to approve the work under some hire or company contracts — which is why it is quicker to settle whose motor it is before our engineers get there. Call 0333 366 0103 once you have got that ready — or, if the vehicle is at home, going nowhere, use . ## Downall Green fuel drain on its way? While you wait Stick to these: kindly meant help does the harm during the wait. - Where your car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before your car. - Not to roll it a few yards, not to check it is all right, not for a passer-by's favour: nobody starts it. - Additives remain in the boot. Injector cleaner and two-stroke oil draw none of the petrol out once more. - A home-made drain leaves your fuel that has already gone beyond your tank, and siphoning petrol by the road is dangerous besides. - Not for your radio, not for your windows: your ignition remains off. ## When the van gets there: the fuel drain, step by step - First, three questions: which fuel was put in, the quantity, and has it run? Those answers shape this job, and so our quote follows them. - Your tank is emptied. The tainted mixture comes from your tank. - Purging your lines comes next, because a motor that ran has petrol past that tank, inside the lines themselves. - Then the fuel filter: changed where there is a usable one, cleared where there is not. - Priming follows once clean diesel is in. - Starting the car. Once the fuel system is bled with clean diesel, our engineers start the engine and confirm it runs smoothly. Till it runs on clean diesel, our technicians remain with it. Your car goes back to normal driving straight away, and permanent damage is very rare if it has been noticed early. ## Downall Green, after your fuel drain: back on the road - Nothing unusual is needed after a start with fresh diesel — usual driving will do. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over then ring us back. - Keep your documents. A hire firm, 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 Downall Green itself Downall Green is a suburban area in Merseyside, situated near the River Douglas and characterised by semi-detached housing.
