Pause there. Hasn't been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever your car has stopped — and nothing decides that more than these next few minutes do. From now on, step by step, for anywhere in Hailsham: ## Petrol in a diesel, motor off — the first minute Go through these in sequence, first. - Ignition off, keys out. Switched on, the ignition can prime the system — and priming is what draws petrol out of the tank towards the parts it damages. - A fuller tank of the same mix is all topping up gives you, since it removes nothing. So no more diesel. - Hazard lights on. If you're anywhere close to moving traffic, make your car easy to see before you do anything else. - Off the pump by hand. At a forecourt, get the attendants to help you roll it away from the petrol pump. Don't fire it up to shift it, however short the way. - The first thing you will be asked is which fuel went in and about how much — and your receipt shows both. Keep it. If you were still driving when you noticed, stop somewhere sensible rather than pushing on for the services — on the M23, under 25 miles from Hailsham, that means the next junction. Stage one comes next. ## Every Hailsham fuel drain starts here: has the engine run? From this point on, everything comes down to a single answer. Not run, not even once: - Only that tank has petrol in it so far. - Where the car stands is usually where this work happens: a drain, then a flush. - No position is better, and it is why the first step matters so much. Engine run, even briefly? - The lines and your filter now carry petrol pulled out of the tank. - The high-pressure pump as well as the fuel injectors get it on a bigger run. - Miles is what turns it into a larger job: flushed lines, a filter seen to, and at times further work. The reason the line falls there: diesel lubricates the high-pressure pump as well as the injectors as it flows through them, and petrol does not. Petrol resting in a tank harms nothing. Once it is pumped, petrol starts wearing down whatever moves it. ## What to have prepared when you call about petrol in a diesel from Hailsham Whether the technician circles or finds you comes down to a little preparation. - BN27 1 and the remainder of the postcode makes the ideal way to begin telling us where you are. - Name the road — High Street or wherever you have pulled up — or the car park. - What a car park serves is the quickest way to find it, and so say the landmark — like the one outside Tesco. - The vehicle. Make, model, and that it is a diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Hailsham page. - How much. Litres from your receipt, or how long the nozzle was in the filler. - If it has run, how far and how heavily — and whether it's run at all. - Settle who has the car before our engineers get there: some hire or company contracts want the owner to approve the work, and that is faster beforehand. Call 0333 366 0103 once you have got that together — or, if the car is at home, going nowhere, use . ## The wait for a Hailsham fuel drain, and what to do in it The wait is where well-intended help does the damage. Hold to these. - Where the car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before the car. - No one — however kind — starts it, whether to see if it runs or to shift your car a short way. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - Siphoning petrol into a can by the kerbside is risky — and it still leaves whatever fuel has already gone beyond the tank. Do not try a home-made drain. - The ignition stays off. Even for the radio or the windows. ## Van arrived? The fuel drain, one stage at a time - The price comes after three queries, not before them — what went in, how much, and if it's run — because those answers set the job. - Emptying it is how that mixture gets taken from the tank. - Purging your lines follows, because a car that ran has petrol past your tank, in your lines themselves. - Cleared, or swapped if the vehicle has a workable one: the filter is seen to next. - Fresh diesel in, and your system primed. - Starting the car. When the system is primed with fresh diesel, our technicians start the car and check it runs smoothly. The car has fresh diesel running through it before our technicians head off. The car returns to normal driving right away, and permanent damage is very uncommon when it has been noticed quickly. ## Back on the road around Hailsham after your fuel drain - Started on new diesel, it needs nothing special of you. Simply drive normally. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or the throttle hesitating: pull over and call us back. - Keep the paperwork. A hire firm, a fleet manager or an insurer may ask what was done. - Next time, trust the pump's label instead of the colour of its handle. ## About Hailsham Hailsham is a town in East Sussex, situated inland at an elevation of 31 metres, approximately 17.7 miles north of Brighton and Hove.
