Engine off. Leave it that way — no second on, no moving it at all. Cleared then rinsed, just where it is: that's normally all an unrun diesel with petrol in it takes. Whether it remains that simple depends on the minutes to come more than on anything else. Anywhere you happen to be in Rollestone, this is how things run from now. ## Engine off: minute one with petrol in a diesel Do the following first, in this order. - Bleeding the system draws petrol from your tank towards the parts it damages, and turning the ignition on can be enough to do that. So your keys come out, and the ignition stays off completely. - A bigger tank of the same mix is all topping up gives you, since it removes nothing. So no more diesel. - Near moving traffic? Then your hazards come on before anything else, and so your car is simple to see. - However short the way, starting it to shift it is the mistake. On a forecourt, push the car clear of the petrol pump by hand instead, then ask the attendants to lend a hand. - The first question we will ask is which fuel went in and about how much — and the till receipt shows both. Hold on to it. Still driving when you realised? Come off the M27 at the next junction if that is where you are, under 25 miles from Rollestone, and stop somewhere safe instead of pushing on to the services. Then begin at stage one. ## Every Rollestone fuel drain starts here: has your motor run? Everything after this point depends on one answer. Motor not run at all? - Nowhere but that tank: that's where the petrol yet is. - Where the car stands is usually where this work happens: a drain, then a flush. - Stage one counts for precisely this reason: it's the best position to be in. Engine run, however briefly? - From that tank, past the filter, into the fuel lines: that's how far that petrol has travelled. - A bigger run carries it all the way to the high-pressure fuel pump and the injectors. - The further it went, the bigger this job — your lines, the filter, and sometimes more besides. Why the line falls there: diesel lubricates the high-pressure fuel pump as well as your injectors as it flows through them, and petrol does not. In the tank, left alone, petrol does no harm. Petrol being pumped is grinding down the parts that shift it. ## What to have ready when you call about petrol in a diesel from Rollestone A van that circles versus a technician that finds you: a little preparation is what separates them. - The best start is a postcode — one beginning SP3 4 — for where you have stopped. - A road name helps: Rollestone Road, say, or whatever street you have stopped in. A car park does the trick too. - Name a car park by what it serves — the one at Siam Smile Asian Supermarket, for example — and it is far easier to find. - Make and model of your car, and the fact it's a diesel. - Which went in counts: AdBlue is a separate job from petrol, plus Rollestone has a page for it. So tell us. - Roughly how much — in litres from the receipt, or by how long the nozzle stayed in. - Has it run? If so, say how far it went, and how it was driven. - The owner may have to authorise the work under some hire and company contracts — so it's quicker to settle whose vehicle it is before our engineers arrive. Next, 0333 366 0103. Not time-critical, the car parked at home with nowhere to be? Then works as well. ## Whilst you wait for a fuel drain around Rollestone Help, however well meant, is the thing that does the harm while you wait. So stick to these. - Stay with your car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - A helpful passer-by does not start it. Nor does anyone checking it still works, or moving it a couple of yards. - Additives stay in the boot. Injector cleaner and two-stroke oil take none of the petrol out once more. - No DIY clearing. Siphoning petrol into a can by the kerbside is dangerous, and it leaves your fuel that has by now gone beyond your tank. - Even your radio or your windows aren't worth switching your ignition on for. ## When our van gets there: the fuel drain, step by step - Three questions. What got in, how much, and if it's run. The replies shape the job, which is why our quote comes after them and not before. - That tank is drained. The contaminated mix comes from the tank. - Purging the fuel lines comes next, since a motor that ran has petrol past your tank, in the lines themselves. - The fuel filter is seen to. Cleared, or replaced where the vehicle has a workable one. - Clean diesel goes in, then the system is primed. - The first start on clean diesel. Once bleeding is finished, your engine is fired up and our engineers confirm that it runs smoothly. The car has new diesel running through it before we go. Permanent damage is very uncommon when it has been caught soon, so the car can go straight back to normal driving. ## Back on the road in Rollestone after the fuel drain - Started on new diesel, it needs nothing unusual of you. Just drive normally. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your 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 done. - Next time, trust the petrol pump's label rather than the colour of its handle. ## About Rollestone and where it is Rollestone is a suburban area in Wiltshire, situated on the riverside at an elevation of 86 metres, with detached housing being the predominant type of accommodation.
