Here Is What Happens Not for a second, and not to move it: your engine remains off. Stop there. Hasn't been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever your car has stopped — and nothing settles that as much as the next few minutes do. Wherever you happen to be in Ballyclare, this is the order things go from here. ## Petrol in a diesel, engine off — the first minute Work through these first, in this order. - Keys out of your ignition. Switching the ignition on can be enough to prime the fuel system, while priming pulls petrol out of your tank towards the components it harms. Leave it off altogether. - No diesel on top. More fuel in takes away none of the petrol — it just makes you with more of the same blend. - Hazards on. If you're anywhere close to moving traffic, make your car simple to see before you do anything else. - However short the way, starting it to shift it is the mistake. On a forecourt, roll it clear of the pump by hand instead, and ask the attendants to lend a hand. - Which fuel, and roughly how much? Your receipt replies that, and that is where our questions start. Never bin it. If you were still driving when you noticed, stop somewhere safe rather than pushing on for the services — on the M77, over 50 miles from Ballyclare, that means the next junction. Stage one follows. ## Has it run yet? The fork in each Ballyclare fuel drain From this stage on, everything comes down to a single answer. If it has never been started: - The petrol is still in the tank and nowhere else. - A drain and flush, on the spot, is usually the whole job. - This, here, is the best position to be in, and the whole reason step one counts. Run at all, however briefly: - Petrol has been drawn out of your tank, past the fuel filter then into the lines. - On a longer run it has got to the high-pressure fuel pump and your injectors. - Lines flushed, your filter seen to, and sometimes more: the job grows as the distance does. The reason the line falls there: diesel lubricates your high-pressure pump as well as the fuel injectors as it flows through them, and petrol doesn't. In that tank, left alone, petrol does no harm. The parts that shift it are wearing the moment petrol is being pumped. ## What to have ready when you call about petrol in a diesel from Ballyclare Whether the technician goes round or finds you comes down to a little preparation. - The best place to start is a postcode — one beginning BT39 9 — for where you are. - The street or the car park. A road name is a help — B738, or wherever you have stopped. - What a car park serves is the easiest way to find it, and so mention the landmark — such as the one outside the local shops. - Tell us what the car is — make, model — and check it is diesel. - What was put in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Ballyclare, and so tell us which. - How long the nozzle was in, or the litres from your receipt — either tells us how much. - Whether it has run. And if it has, how far plus how hard. - The owner may have to authorise the work under some hire and company contracts — which is why it's faster to settle whose motor it is before our technicians get there. Then phone 0333 366 0103. If it can wait — the car is at home and going nowhere — works too. ## Whilst you wait for a fuel drain in Ballyclare Hold to these: kindly meant help causes the harm during the wait. - Your safety comes before your car. Somewhere dangerous? Get clear of the traffic then wait away from it. Fine where it is? Stay with it. - Not to roll it a few yards, not to check it is all right, not for a passer-by's favour: no one starts it. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of that gets the petrol back out. - Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond the tank remains where it is regardless. - Even your radio or your windows are not worth turning the ignition on for. ## When our van arrives: the fuel drain, step by step - First, three questions: which fuel got in, the amount, and has it run? Those replies decide the job, and so our quote follows them. - That tank is drained. The tainted blend comes out of the tank. - The lines are cleaned. If it ran, that petrol has moved beyond your tank, and your lines are carrying it. - Where your car has a workable filter, it's changed; if not, cleared. - Bleeding the system comes after fresh diesel is in. - The start. With fresh diesel in and the fuel system bled, it's fired up and tested to be sure it runs smoothly. Till it runs on fresh diesel, our technicians stay with it. When it has been spotted quickly, long-term damage is very rare, and your car returns to normal use straight away. ## Ballyclare, after your fuel drain: back on the road - Nothing unusual is needed after a start with fresh diesel — ordinary driving is all. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and call us once more. - The work may matter later with a hire company, an insurer or a fleet manager. Keep your paperwork. - Next time, trust the petrol pump's label instead of the colour of its handle. ## About Ballyclare itself Ballyclare is a town situated inland in County Antrim, Northern Ireland.
