Petrol in a diesel that has not been run is typically a simple drain plus a flush, done where your vehicle stands, and what happens in the next few minutes settles that far more than anything else. What follows is the sequence from this point, wherever around Newmilns you happen to be. ## Petrol in a diesel, engine off — the first minute Do these first, in this order. - Take the keys out. Even the ignition on its own can prime the fuel system, drawing petrol out of the tank to exactly the components it harms, so keep the car alone entirely. - Do not top it up with diesel. Adding diesel takes out nothing. You are left with a bigger tank of the same mix. - Get the car simple to see first — hazards on — if there is traffic going past anywhere near you. - The staff will usually help you push it away from the petrol pump. Ask, and move it by hand — never under the motor, even for a few yards. - Keep your receipt. It shows which fuel got in and roughly how much, which is the first thing we'll ask. Still on the move when you realised? Come off the M77 at the next exit if that is where you are, under 10 miles from Newmilns, and stop somewhere sensible and not pressing on to the services. Then start at step one. ## Has it run yet? The fork in every Newmilns fuel drain From this stage on, everything comes down to a single answer. Not run, not even once: - The petrol sits in the tank, and only there. - Draining and flushing, on the spot, is normally all of that. - This, here, is the best spot to be in, and the reason step one counts. Motor run, even for a moment? - Out of the tank, through the fuel filter, into the lines: that is how far the petrol has got. - A longer run takes it right through to the high-pressure pump and the fuel injectors. - The further it went, the bigger this job — the 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 flows through them, and petrol does not. In your tank, sitting still, petrol does no harm. Once it is pumped, petrol begins grinding whatever moves it. ## Before you call about petrol in a diesel in Newmilns: what our technicians need Whether the technician goes round or finds you comes down to a little planning. - Where you have stopped. A postcode starting KA16 9 is the best start. - The street or the car park. A road name is a help — Craigview Road, or wherever you have pulled up. - Car parks are located more easily by what they serve: tell us the one outside Co-op, and it's simple. - The make and model of your vehicle, and the fact it is a diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Newmilns page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - The mileage it did, and how hard, if it has run at all. - Hire or company car? Some agreements want the owner's go-ahead for this work, and sorting it before our technicians arrive is faster than afterwards. Then phone 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## Waiting for a fuel drain in Newmilns: what to do Help, however well meant, is what does the damage whilst you wait. So hold to these. - Your safety comes before the vehicle. Somewhere exposed? Get clear of the traffic then wait away from it. Safe where it stands? Wait with it. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's favour: nobody starts it. - Additives stay in your boot. Injector cleaner and two-stroke oil draw none of the petrol out again. - Siphoning petrol into a can by the roadside is risky — and it also leaves whatever fuel has already gone beyond the tank. Don't drain the car yourself. - The ignition remains off. Even for the radio or the windows. ## When the van gets there: your fuel drain, step by step - First, three questions: which fuel was put in, the volume, and has it run? Those replies shape this job, and so our price follows them. - Out of that tank comes the contaminated mix: the tank is drained. - Your lines are purged. If it ran, the petrol has moved beyond the tank, and your lines are carrying it. - Where your car has a serviceable filter, it is swapped; otherwise, cleared. - Fresh diesel goes in, then the fuel system is primed. - Our engineers fire it up only after new diesel has gone in and primed the system, then make sure that it is running properly. The car has fresh diesel running through it before we leave. Lasting damage is very uncommon when it has been noticed early, so your car can go straight back to normal driving. ## Back on the road in Newmilns after your fuel drain - Drive normally. There's nothing special to do after it has been started on fresh fuel. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle stumbling: pull over and ring us back. - An insurer, a fleet manager or a hire company may ask what was done, so hold on to your paperwork. - The handle's colour isn't the thing to go by next time — the label on the petrol pump is. ## About Newmilns and where it is Newmilns is a town situated on the banks of the River Irvine in East Ayrshire, with a mix of semi-detached housing and other residential properties.
