Here Is What Happens Whatever you do, don't switch your engine on, even briefly, to move the car. Stop; leave it off. Petrol in a diesel that has not been run is typically a drain plus a flush, done right where the vehicle sits, and what you do in the next few minutes decides that far more than anything else. From now on, step by step, for anywhere in Heathpark: ## Engine off: minute one with petrol in a diesel In this sequence, all before everything else: - Keys out of the ignition. Turning your ignition on can be enough to prime the system, while priming draws petrol out of the tank toward the parts it harms. Leave the car off completely. - A bigger tank of the same mix is all adding diesel gives you, since it takes out nothing. So no extra diesel. - Hazards on. If you are anywhere close to moving traffic, make the car easy to see before you do anything else. - Off the pump by hand. On a forecourt, ask the attendants to help you roll it clear of the pump. Do not crank it to move it, however short the distance. - Keep your receipt: the grade and roughly how much are written on it, and they're what our technicians ask about first. Still on the move when you realised? Come off the M5 at the next junction if that's where you are, under 10 miles from Heathpark, and stop somewhere safe and not pressing on to the services. Then begin at stage one. ## Has it run yet? The fork in every Heathpark fuel drain One answer is what everything after this point depends on. Engine never run at all? - Just that tank has petrol in it so far. - The work is a drain and a flush, usually done where the vehicle stands. - This, here, is the best spot to be in, and the reason step one matters. If your engine has run, even briefly: - Out of the tank, past the fuel filter, into the fuel lines: that is how far the petrol has got. - On a bigger run it has reached your high-pressure pump as well as your injectors. - The further it went, the larger the job — the fuel lines, your filter, and sometimes more besides. That line falls there since diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol doesn't. In the tank, sitting still, petrol does no harm. Once it's pumped, petrol begins wearing down whatever moves it. ## What to have prepared when you call about petrol in a diesel from Heathpark Whether the technician goes round or finds you comes down to a little planning. - EX14 1 plus the remainder of the postcode is the best way to start telling us where you are. - A road name is a help: Devonshire Road, say, or whatever street you have stopped in. A car park does the trick too. - Car parks are found more easily by what they serve: say the one at Lidl, and it's easy. - Say what the vehicle is — make, model — and confirm it's diesel. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Heathpark page. - How long the nozzle was in, or the litres on the receipt — whichever gives us how much. - Whether it's run. And if it has, how far plus how heavily. - Hire or company car? Some contracts want the owner's go-ahead for the work, and sorting it before we get there is faster than afterwards. Next, 0333 366 0103. Not time-critical, the car left at home with nowhere to be? Then will do as well. ## While you wait for a fuel drain in Heathpark The wait is where well-meant help does the harm. Stick to these. - Safety before the vehicle. If it has stopped somewhere dangerous, get yourself away from the traffic and wait away from it. If it's safe where it stands, stay with it. - A kind passer-by does not crank it. Nor does anyone checking it still does the trick, or moving it a few yards. - None of that takes that petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives. - A DIY drain misses the fuel that has already gone beyond the tank, and siphoning petrol by the road is hazardous besides. - Even your radio or your windows aren't worth switching your ignition on for. ## When our van gets there: your fuel drain, step by step - First, three questions: which fuel was put in, the quantity, and has it run? Those answers shape the job, and so our price follows them. - Your tank is emptied. The polluted mix comes out of the tank. - Petrol that has moved beyond that tank sits in your lines once it ran, and the fuel lines are rinsed to shift it. - Cleaned, or swapped if the car has a usable one: the filter is seen to next. - Priming comes once fresh diesel is in. - We fire it up only after fresh diesel has gone in and bled the system, then check that it is running properly. The vehicle has clean diesel running through it before our engineers go. Permanent damage is very uncommon when it has been caught early, so your car can go right back to normal driving. ## Heathpark, after your fuel drain: back on the road - Started on clean diesel, it needs nothing special of you. Simply drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop then call us once more. - The work may matter later with a hire company, an insurer or a fleet manager. Hold on to your documents. - The handle's colour is not the guide to go by next time — the label on the petrol pump is. ## About Heathpark, for a moment Heathpark is a suburban area situated on the riverside in Devon, with an elevation of around 94 metres.
