Here Is What Happens Stop, and keep the engine off — not on, and not for a moment to shift the car. The coming few minutes settle it far more than anything else: petrol in a diesel still unrun generally amounts to clearing and cleaning, on the spot. Wherever you are in Blindley Heath, here is the order things go from here. ## Petrol in a diesel? What to do in minute one Work through the following before anything else, in this order. - Priming the fuel system draws petrol from your tank towards the parts it damages, and switching your ignition on can be enough to do that. So your keys come out, and your ignition remains off completely. - Don't top it up with diesel. Adding diesel takes out nothing. You end up with a fuller tank of the same mix. - Get your car simple to see before anything else — hazard lights on — if there's moving traffic anywhere close to you. - By hand, never on the engine: that is how it comes off the pump. Get the forecourt staff to help you roll, whatever the distance. - Keep your receipt: the grade and the rough amount are printed on it, and they're what our technicians ask about first. Still driving when you realised? Come off the M23 at the next exit if that's where you are, under 5 miles from Blindley Heath, and stop somewhere sensible instead of pressing on to the services. Then start at step one. ## Has it run yet? The fork in each Blindley Heath fuel drain One answer is what everything after this stage depends on. Not run, not even briefly: - Only that tank has petrol in it for now. - Usually it's drained and cleaned just where your car is. - This is as good as it gets — which is the entire point of stage one. Run at all, even for a second: - Petrol has been drawn from that tank, through your filter then into your lines. - The high-pressure pump as well as your injectors get it on a longer run. - Mileage is what makes it a bigger job: the lines flushed, a filter seen to, and at times further work. The reason the line falls there: diesel lubricates the high-pressure fuel pump and the injectors as it flows through them, and petrol does not. Nothing is harmed by petrol that is just resting in a tank. Once it is pumped, petrol starts wearing down whatever moves it. ## Before you call about petrol in a diesel in Blindley Heath: what our technicians need Whether the van goes round or finds you depends on a little preparation. - The ideal start is a postcode — one starting RH7 6 — for where you have stopped. - A road name helps: St. John's Meadow, say, or whatever street you've stopped in. A car park does the trick too. - Or the landmark. A car park is easier to find by what it serves, such as the one at Co-op Food. - The vehicle. Make, model, and that it is a diesel. - What got in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Blindley Heath, and so say which. - How much. Litres from the receipt, or how long the nozzle was in. - Whether it has run. And if it has, how far and how hard. - Whose vehicle it is. Some hire or company contracts want the owner to authorise this work, and that is easier settled before our engineers arrive than after. Phone 0333 366 0103 then. Writing to works too if it can wait, with the vehicle parked at home, going nowhere. ## Blindley Heath fuel drain on its way? Whilst you wait During the wait, the damage comes from well-meant help — which is why these count. - Where the vehicle has stopped decides where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of the vehicle. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll 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. - Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank remains where it is regardless. - Even the radio or the windows are not worth switching the ignition on for. ## When our van gets there: your fuel drain, step by step - Fuel, volume, whether it has run: the answers decide the job, and that's why we give a price after them instead of before. - Emptying it is how the blend gets taken from your tank. - Your lines are purged. If it ran, that petrol has shifted beyond the tank, and the fuel lines are holding it. - Where your car has a serviceable filter, it's replaced; otherwise, cleared. - Bleeding your system comes once clean diesel is in. - The first start on clean diesel. Once priming is complete, your engine is fired up and our engineers make sure that it runs properly. The car has fresh diesel running through it before our engineers leave. Your car goes back to normal use right away, and long-term damage is very rare if it has been noticed early. ## After the fuel drain: back on the road in Blindley Heath - Nothing unusual is needed after a start with clean diesel — ordinary driving is all. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over then call us back. - Keep the paperwork. A hire firm, a fleet manager or an insurer may ask what was done. - Read the label on the petrol pump next time, not the colour of the handle. ## About Blindley Heath, briefly Blindley Heath is a village in Surrey, situated on the riverside at an elevation of 68 metres, with semi-detached housing being the predominant type of accommodation.
