Stop there. The coming few minutes decide it more than anything else: petrol in a diesel still unrun normally comes down to emptying then cleaning, on the spot. From now on, in order, for anywhere in Hatch Warren: ## Petrol in a diesel, engine off — the first minute Work through the following in order, first. - Keys out of your ignition. Turning your ignition on can be all it takes to prime the system, while priming draws petrol out of your tank towards the components it harms. Leave the car off altogether. - A fuller tank of the same mixture is all adding diesel gives you, since it takes out nothing. So no extra diesel. - Hazards on. If you're anywhere near moving traffic, make your car simple to see before you do anything else. - Off the petrol pump by hand. At a forecourt, get the staff to help you push it clear of the pump. Do not fire it up to shift it, however short the way. - Keep your receipt: the grade and roughly how much are printed on it, and they're what we ask about first. Still on the move when you noticed? Come off the M3 at the next junction if that's where you are, under a mile from Hatch Warren, and pull over somewhere sensible rather than pushing on to the services. Then begin at stage one. ## Hatch Warren fuel drain: has your engine run yet, or not? What happens after this rests on one answer, and only one. Engine not run at all? - No place but the tank: that is where the petrol yet is. - Normally it is drained and purged just where the car is. - No spot is better, and it's why the first step counts so much. If your engine has been run, even for a moment: - Some petrol has left the tank already, passed through your filter, and got into the lines. - On a longer run it has reached the high-pressure fuel pump and the injectors. - Distance is what makes it a bigger job: the lines flushed, a filter seen to, and at times further work. Diesel keeps your high-pressure pump and the fuel injectors oiled as it runs through them. Petrol offers them nothing, and that's why the line is drawn there. Nothing is damaged by petrol that is only sitting in a tank. Move the petrol, though, and it wears the very parts that move it. ## What to have prepared when you call about petrol in a diesel from Hatch Warren A little preparation is the difference between a technician that finds you and a van that goes round. - RG22 4 and the remainder of the postcode is the best way to begin telling us where you are. - The street or the car park. A road name helps — Woodbury Road, or wherever you have stopped. - Car parks are found more easily by what they serve: tell us the one outside Sainsbury's, and it's easy. - Make and model of the vehicle, and the fact it's a diesel. - Tell us which got in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Hatch Warren. - The amount: the receipt's litres, or else how long you held the nozzle in. - Whether it's run. Then if it has, how far plus how heavily. - Whose car it is. Some hire or company agreements want the owner to authorise this work, and that is quicker settled before our engineers arrive than after. Then phone 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — does the trick too. ## Whilst you wait for a fuel drain around Hatch Warren Stick to these: kindly meant help causes the harm during the wait. - Wait with the vehicle if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - Nobody — however helpful — starts it, whether to see if it runs or to shift the car a short way. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it gets the petrol back out. - A home-made drain misses your fuel already gone beyond your tank, and siphoning petrol by the road is hazardous too. - Not for the radio, not for the windows: your ignition remains off. ## When the van arrives: the fuel drain, step by step - Three queries. What was put in, how much, and whether it has run. Those answers decide the job, which is why the price comes after them but not before. - Out of that tank comes the contaminated blend: the tank is cleared. - If it ran, the fuel lines are carrying petrol that has moved beyond the tank — so they're purged. - Cleaned, or changed if your car has a serviceable one: your filter is seen to next. - Fresh diesel in, and the system primed. - Our technicians fire it up only after clean diesel has gone in and primed the fuel system, then make sure that it's running properly. Only once it is running on new diesel do our engineers head off. It's very uncommon for a vehicle spotted quickly to be left with permanent damage, and normal driving starts again right away. ## Hatch Warren, after the fuel drain: back on the road - Nothing unusual is needed after a start with fresh diesel — usual driving will do. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or the throttle hesitating: pull over then call us back. - An insurer, a fleet manager or a hire company may ask what was carried out, and so hold on to the documents. - Next time, check the petrol pump. The label, not the colour of its handle. ## About Hatch Warren itself Hatch Warren is a suburban area in Hampshire, situated inland at an elevation of around 145 metres, with detached housing being the predominant type of accommodation.
