Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever the vehicle has stopped — and no other factor settles that as much as the next few minutes do. Here's the sequence of things from now, wherever you are around Mayfield. ## Petrol in a diesel, motor off — the first minute First, the following — following this order. - Take your keys out. Even the ignition on its own can prime your fuel system, pulling petrol out of your tank to precisely the parts it damages, and so leave the vehicle off entirely. - A fuller tank of the same mix is all adding diesel leaves you, because it takes out nothing. So no more diesel. - Near passing traffic? Then your hazards go on before everything else, so the car is simple to see. - Off the pump by hand. At a forecourt, get the attendants to help you roll the vehicle away from the petrol pump. Don't crank it to move it, however short the way. - Which fuel, and about how much? Your receipt answers both, and that's where our questions start. Don't bin it. Still on the move when you noticed? Come off the M23 at the next exit if that's where you are, under 25 miles from Mayfield, and pull over somewhere sensible and not pushing on to the services. Then begin at step one. ## Has it run yet? The fork in every Mayfield fuel drain From this stage on, everything hinges on a single answer. Not run, not even once: - That petrol is still in that tank and nowhere else. - Where the vehicle sits is usually where the work is done: a drain, then a flush. - This is as good as it gets — which is the whole point of stage one. Engine run, however briefly? - From that tank, through your filter, into the fuel lines: that's how far the petrol has travelled. - On a longer run it has reached the high-pressure fuel pump and the injectors. - Flushing the lines, the fuel filter seen to, and sometimes more: this job grows as the miles does. Diesel keeps the high-pressure fuel pump and your injectors lubricated as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. A tank of petrol, left still, hurts nothing. Once it is pumped, petrol begins grinding whatever moves it. ## What to have prepared when you call about petrol in a diesel from Mayfield Whether the technician circles or finds you depends on a little planning. - Your whereabouts: a postcode starting TN20 6 works best. - A road name helps: High Street, say, or whatever street you've stopped in. A car park works too. - Or the landmark. A car park is quicker to find by what it serves, like the one outside Spar. - Say what your car is — make, model — and confirm it is diesel. - Which was put in counts: AdBlue is a separate job from petrol, plus Mayfield has a page just for that. So tell us. - The amount: your receipt's litres, or otherwise how long you held the nozzle in. - Has it run? If so, tell us how far it went, and the way it was driven. - Sort who owns your car ahead of when we arrive: some hire or company agreements want the owner to approve this work, and that is faster first. Then call 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## Waiting for a fuel drain in Mayfield: what to do The wait is where well-intended help does the harm. Stick to these. - Your safety comes before the vehicle. Somewhere exposed? Get clear of the traffic and wait away from it. Safe where it stands? Wait with it. - A kind passer-by doesn't crank it. Nor does anyone wanting to check it still works, or moving it a few yards. - Something from your boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol. - A home-made drain misses your fuel already gone beyond your tank, and siphoning petrol by the road is dangerous too. - Leave your ignition off — your windows and the radio included. ## Step by step: your fuel drain when our van arrives - Our quote comes after three questions, not before them — what got in, how much, and whether it has run — because the answers decide this job. - Then that tank is emptied, so the tainted fuel comes out. - The lines are purged. If it ran, the petrol has moved beyond your tank, and your lines are holding it. - The filter is sorted. Cleared, or swapped where the car has a usable one. - The system is primed on clean diesel. - First start on fresh diesel. When bleeding is complete, the engine is started and our technicians confirm that it runs correctly. Only once it's running on new diesel do our technicians head off. The car goes back to normal driving at once, and permanent damage is very uncommon when it has been caught quickly. ## Mayfield, after your fuel drain: back on the road - Started on fresh diesel, it needs nothing special of you. Just drive normally. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle means pull over and ring us back. - The work may come up later with a hire firm, an insurer or a fleet manager. Keep your documents. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Mayfield Mayfield is a rural village in East Sussex, situated inland at an elevation of around 136 metres.
