Motor off. Leave it like that — no moment on, no shifting it anywhere. Has not been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever the car has stopped — and no other factor decides that more than the next few minutes do. Below is the sequence from this point, anywhere in Wannock you happen to be. ## Petrol in a diesel? What to do in minute one Do the following first, in this sequence. - The keys out of the ignition. Turning your ignition on can be enough to prime the system, and priming pulls petrol out of your tank towards the components it damages. Keep the vehicle off altogether. - Topping up with diesel sounds like it thins the trouble. It does not: nothing comes out, and your tank just holds more of the same. - Hazards on. If you're at all near moving traffic, make the vehicle simple to see before you do anything else. - However short the way, starting it to shift it is the mistake. At a forecourt, roll the car away from the petrol pump by hand instead, and ask the attendants to help. - The first thing we will ask is which fuel went in and roughly how much — and the receipt says both. Hold on to it. Still on the move when you noticed? Come off the M23 at the next junction if that's where you are, under 50 miles from Wannock, and pull over somewhere sensible rather than pushing on to the services. Then begin at stage one. ## Wannock fuel drain: has the engine run yet, or not? One answer is what everything after this point rests on. If it has not once been started: - No place but that tank: that is where the petrol yet is. - The job is a drain and a flush, normally done where the car is. - Being here is as good as it gets — which is the whole point of step one. If the engine has run, even briefly: - From the tank, through your filter, into your lines: that's how far the petrol has got. - The high-pressure fuel pump as well as your injectors get it on a bigger run. - The job expands with the miles — lines rinsed, filter sorted, occasionally more. Diesel keeps the high-pressure pump and the fuel injectors lubricated as it runs through them. Petrol offers them nothing, and that is why the line is drawn there. Petrol resting in a tank damages nothing. Pump that petrol, though, and it wears the very parts that move it. ## What to have ready when you call about petrol in a diesel from Wannock A little preparation is the difference between a van that finds you and a technician that goes round. - The best place to start is a postcode — one starting BN26 5 — for where you are. - Wherever you have parked, the road's name is useful — whether that's Wannock Lane or somewhere else — and so does the name of a car park. - Car parks are located more easily by what they serve: tell us the one outside Lidl, and it's simple. - Say what your vehicle is — make, model — and check it's diesel. - Tell us which went in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Wannock. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - If it has run, how far plus how heavily — as well as whether it's run at all. - Hire or company car? Some agreements need the owner's go-ahead for this work, and sorting it before our engineers turn up is quicker than after. Then call 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — does the trick too. ## The wait for a Wannock fuel drain, and what to do in it Help, however well meant, is what does the harm whilst you wait. So stick to these. - Your safety comes before your car. Somewhere exposed? Get away from the traffic then wait away from it. Fine where it sits? Wait with it. - A kind passer-by doesn't crank it. Nor does anyone wanting to check it still does the trick, or moving it a few yards. - None of that takes the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - A DIY drain leaves the fuel that has already gone beyond the tank, and siphoning petrol by the road is dangerous too. - Not for your radio, not for the windows: the ignition remains off. ## Van arrived? Your fuel drain, one step at a time - Our price comes after three questions, not before them — what was put in, how much, and whether it has run — because those replies decide this job. - That tank is drained. The contaminated blend comes out of your tank. - Petrol that has shifted beyond your tank travels in the fuel lines once it ran, and your lines are cleaned to shift it. - The filter is seen to. Cleared, or replaced where the vehicle has a serviceable one. - The system is primed on fresh diesel. - First start on fresh diesel. Once bleeding is done, your engine is started and our technicians check that it runs correctly. Our engineers remain until it is running on clean diesel. It is very rare for a vehicle caught quickly to be left with long-term damage, and normal driving starts again right away. ## After the fuel drain: back on the road in Wannock - After it has been started on fresh fuel, there is nothing special to do: drive normally. - Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or the throttle hesitating: pull over and call us back. - Keep the documents. A hire firm, a fleet manager or an insurer may ask what was carried out. - Check the label on the petrol pump next time, not the colour of the handle. ## About Wannock and where it is Wannock is a small village in East Sussex, situated inland at an elevation of 24 metres, and is located near the towns of Lower Willingdon and Filching.
