Engine off. Keep the car that way — no second on, no moving it at all. Petrol in a diesel that hasn't been run is normally a drain and a flush, done where the car stands, and what you do in the next few minutes decides that far more than anything else. Wherever you are in Garden City, this is how things run from now. ## Petrol in a diesel, engine off — the first minute In this sequence, all before anything else: - The ignition off, keys out. Switched on, the ignition can prime the system — and priming is what moves petrol out of your tank towards the parts it harms. - A fuller tank of the same mixture is all adding diesel gives you, since it takes out nothing. So no extra diesel. - Near moving traffic? Then your hazards come on before anything else, so the vehicle is simple to spot. - The attendants will normally help you roll it away from the petrol pump. Let them, and move it by hand — never on your engine, even for a few yards. - Hold on to the receipt. It shows which fuel went in plus about how much, which is the first thing we'll ask. Still on the move when you realised? Come off the M56 at the next junction if that's where you are, under 5 miles from Garden City, and stop somewhere sensible instead of pressing on to the services. Then start at stage one. ## Has it run yet? The fork in every Garden City fuel drain From this stage on, everything hinges on a single answer. Motor not run at all? - All the petrol remains in that tank, and only there. - Usually it's emptied and purged right where the vehicle is. - Step one counts for precisely this reason: it's the best place to be in. Engine run, even for a moment? - Petrol has been pulled from the tank, past the fuel filter and into the fuel lines. - On a bigger run it has reached the high-pressure fuel pump and the injectors. - Mileage is what turns it into a bigger 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 your injectors on its way through them — and petrol does not. Petrol resting in a tank harms nothing. Pump the petrol, though, and it grinds down the very parts that move it. ## Garden City, petrol in a diesel: have these prepared before you call Get ready a little, and the van finds you instead of circling. - The ideal start is a postcode — one beginning CH5 2 — for where you have stopped. - The street or the car park. A road name helps — Sealand Avenue, or wherever you have pulled up. - What a car park serves is the easiest way to find it, so say the landmark — like the one at Aldi. - Tell us what the vehicle is — make, model — and confirm it's diesel. - What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for Garden City, so tell us which. - The amount: your receipt's litres, or otherwise how long you held the nozzle in. - The distance it did, and how heavily, if it has run at all. - The owner may have to authorise the work under some hire and company contracts — which is why it's faster to settle whose vehicle it is before our engineers get there. Next, 0333 366 0103. Not pressing, your car parked at home with nowhere to be? Then works too. ## Garden City fuel drain on its way? Whilst you wait Help, however well meant, is what does the damage whilst you wait. So hold to these. - Your safety comes before the vehicle. Somewhere unsafe? Get away from the traffic then wait away from it. Safe where it stands? Stay with it. - No one — however helpful — starts it, whether to see if it runs or to shift the car a short way. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it takes the petrol back out. - Siphoning petrol into a can at the roadside is risky — and it still leaves whatever fuel has already gone beyond the tank. Do not try a home-made drain. - Keep the ignition off — the windows and your radio too. ## The fuel drain, step by step, once our van gets there - Three questions. What was put in, how much, and if it has run. The answers set this job, which is why the price comes after them and not before. - Your tank is cleared. The tainted blend comes out of the tank. - If it ran, your lines are carrying petrol that has moved beyond the tank — so they are cleaned. - Then the fuel filter: swapped where there is a serviceable one, cleared where there's not. - Clean diesel in, and the fuel system primed. - Our engineers fire it up only after clean diesel has gone in and bled the system, then confirm that it is running smoothly. Only once it's running on fresh diesel do our technicians leave. The car goes back to normal driving straight away, and long-term damage is very uncommon when it has been caught soon. ## Garden City, after the fuel drain: back on the road - After it has been started on fresh fuel, there is nothing unusual to do: drive normally. - 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. - The paperwork answers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, read the pump. The label, not the colour of the handle. ## About Garden City, briefly Garden City is a village in Flintshire, Wales, situated on the riverside at a low elevation of around 8 metres.
