Pause there. Petrol in a diesel that has not been run is typically a drain plus a flush, done where your vehicle sits, and what happens in the next few minutes determines that far more than anything else. From now on, step by step, wherever you are in Kilwinning: ## Petrol in a diesel? What to do in minute one In this sequence, all before anything else: - Keys out of the ignition. Turning the ignition on can be all it takes to prime the fuel system, and priming pulls petrol out of your tank towards the components it harms. Leave the car off altogether. - A bigger tank of the same mixture is all adding diesel leaves you, because it removes nothing. So no more diesel. - Visibility comes first beside moving traffic: put your hazards on, and only then deal with anything else. - By hand, never on the motor: that's how it comes off the pump. Get the forecourt attendants to help you push, however short the miles. - Which fuel, and about how much? Your receipt answers both, and that is where our first question starts. Don't bin it. On the M77, under 10 miles from Kilwinning, the next exit is the place to come off; anywhere, the first safe spot to stop. Do not press on to the services. Then go back to step one. ## Has it run yet? The fork in each Kilwinning fuel drain From this point on, everything hinges on a single answer. Engine never run at all? - Nowhere but your tank: that's where that petrol still is. - Usually it is drained and purged right where the car stands. - This is as good as it gets — which is the whole point of step one. If your motor has been run, even briefly: - Out of your tank, through your filter, into your lines: that's how far that petrol has travelled. - The high-pressure fuel pump and the injectors get it on a longer run. - The farther it went, the bigger this job — your lines, the fuel filter, and now and then more besides. Why the line falls there: diesel protects your high-pressure pump as well as the fuel injectors as it passes through them, and petrol doesn't. A tank of petrol, left alone, damages nothing. The components that move it are wearing the moment petrol is being pumped. ## What to have prepared when you call about petrol in a diesel from Kilwinning A little preparation is the difference between a van that finds you and a technician that goes round. - Where you are. A postcode starting KA13 6 is the ideal start. - A road name helps: Lauchlan Way, say, or whichever street you have stopped in. A car park works too. - What a car park serves is the quickest way to find it, so mention the landmark — like the one at Co-op Food. - Say what the vehicle is — make, model — and check it is diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Kilwinning page. - How long the nozzle was in, or the litres on the receipt — either tells us how much. - Whether it has run. And if it has, how far plus how hard. - Sort who owns your car ahead of when our technicians get there: some hire and company contracts want the owner to authorise this work, and doing it quicker beforehand. Next, 0333 366 0103. Not time-critical, your car parked at home with nowhere to be? Then will do too. ## Waiting for a fuel drain around Kilwinning: what to do The wait is where well-intended help does the damage. Hold to these. - Safety before the vehicle. If it has stopped somewhere unsafe, get yourself away from the traffic then wait away from it. If it is safe where it is, wait with it. - No one — however helpful — starts it, whether to see if it runs or to shift the car a short way. - Anything from your boot, oil made for two-strokes or injector cleaner: no additive lifts that petrol. - 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. ## The fuel drain, step by step, once the van arrives - Our quote comes after three questions, not before them — what got in, how much, and if it's run — because the answers decide the job. - Then your tank is cleared, so the polluted fuel is taken out. - Rinsing the lines comes next, since a motor that ran has petrol past that tank, in the fuel lines themselves. - Your filter is dealt with. Cleared, or replaced where your car has a workable one. - Fresh diesel in, and your system primed. - Starting up. Once the system is primed with clean diesel, our technicians fire it up and make sure it runs properly. Only once it's running on fresh diesel do we go. When it has been spotted early, long-term damage is very uncommon, and your car returns to normal use right away. ## Back on the road around Kilwinning after the fuel drain - After it's been started on clean fuel, there is nothing special to do: drive normally. - Watch the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle tells you to pull over and ring us back. - Hold on to the documents. A hire company, a fleet manager or an insurer may ask what was carried out. - The handle's colour is not the thing to go by next time — the label on the petrol pump is. ## About Kilwinning Kilwinning is a coastal town in North Ayrshire, situated on the eastern shore of the Firth of Clyde, with a mix of terraced housing and other residential areas.
