The next few minutes determine it far more than anything else: petrol in a diesel that has not run generally amounts to draining and cleaning, on the spot. From now on, step by step, wherever you are around Roundhay: ## Petrol in a diesel, engine off — the first minute Work through these first, in this order. - The ignition off, keys out. Turned on, your ignition can prime your system — and priming is what draws petrol out of the tank towards the components it damages. - No diesel on top. More fuel in takes away none of that petrol — it only leaves you with extra of the same mixture. - Visibility comes before the rest beside moving traffic: switch the hazards on, and only then think about everything else. - The attendants will usually help you roll it clear of the pump. Let them, and roll it by hand — not under the engine, even for a couple of yards. - Which fuel, and about how much? Your receipt replies that, and that's where our first question starts. Never bin it. If you were still driving when you noticed, stop somewhere sensible rather than pushing on for the services — on the Inner Ring Road, under 3 miles from Roundhay, that means the next exit. Step one follows. ## Roundhay fuel drain: has your engine run yet, or not? One answer is what everything after this stage depends on. Not run, not even briefly: - All the petrol remains in that tank, and only there. - Usually it is emptied and flushed right where the car is. - This, here, is the best spot to be in, and the reason stage one matters. If the engine has run, even for a moment: - From the tank, past the filter, into the lines: that's how far the petrol has got. - On a longer run it has got to your high-pressure pump as well as your injectors. - The job grows with the distance — lines rinsed, filter seen to, sometimes more. Petrol does not lubricate. Diesel does, oiling your high-pressure pump and injectors as it flows through, which is why the line falls where it does. In the tank, left alone, petrol does no harm. Once it is pumped, petrol starts grinding whatever moves it. ## Before you call about petrol in a diesel in Roundhay: what our engineers need Get ready a little, and the technician finds you instead of circling. - Your whereabouts: a postcode beginning LS8 2 works best. - The road or the car park. A road name helps — The Carriage Drive, or wherever you have pulled up. - What a car park serves is the easiest way to find it, and so say the landmark — like the one outside The Co-operative Food. - Tell us what your vehicle is — make, model — and check it is diesel. - Which went in matters: AdBlue is a separate job from petrol, and Roundhay has a page for it. So tell us. - The amount: your receipt's litres, or else how long you had the nozzle in. - If it has run, how far and how heavily — as well as whether it's run at all. - The owner may have to authorise the work under some hire and company contracts — which is why it's quicker to settle whose motor it is before our technicians get there. Call 0333 366 0103 once you've got that together — or, if the car is at home, going nowhere, use . ## Roundhay fuel drain on its way? While you wait The wait is where kindly meant help does the harm. Hold to these. - Your safety comes before the car. Somewhere dangerous? Get clear of the traffic and wait away from it. Safe where it is? Stay with it. - Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a couple of yards. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of that takes the petrol back out. - No DIY emptying. Siphoning petrol into a can at the kerbside is risky, and it leaves your fuel that has already gone beyond your tank. - Not for the radio, not for the windows: your ignition remains off. ## Step by step: your fuel drain when the van arrives - The price comes after three queries, not before them — what was put in, how much, and whether it's run — because those answers shape the job. - Next the tank is emptied, so the polluted fuel is taken out. - Rinsing the fuel lines comes next, since a car that ran has petrol past your tank, inside your lines themselves. - Where your car has a serviceable filter, it's swapped; if not, cleared. - Clean diesel goes in, then the system is primed. - Our engineers fire it up only after fresh diesel has gone in and primed your system, then make sure that it's running properly. Our technicians wait until it's running on new diesel. Your car goes back to normal driving right away, and lasting damage is very unusual if it has been caught soon. ## After your fuel drain: back on the road in Roundhay - After it has been started on clean fuel, there's nothing unusual to do: drive normally. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop then call us a second time. - The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to the paperwork. - The handle's colour isn't the thing to go by next time — the label on the petrol pump is. ## About Roundhay, briefly Roundhay is a suburban area in West Yorkshire, situated near the River Aire and close to the city of Leeds.
