Here Is What Happens Whatever you do, never switch the engine on, even for a moment, to move the vehicle. Pause; leave the vehicle off. Drained and rinsed, just where it is: that's generally all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes ahead more than on everything else. From here on, in order, for anywhere in Great Blakenham: ## Petrol in a diesel? What to do in minute one Work through the following in sequence, before you do anything else. - Keys out of your ignition. Switching your ignition on can be all it takes to prime the fuel system, while priming draws petrol out of your tank towards the parts it harms. Keep the car off altogether. - No diesel on top. More fuel in takes away none of that petrol — it only makes you with more of the same mixture. - Being seen comes first beside moving traffic: switch the hazards on, and only then deal with everything else. - The staff will usually help you push it away from the pump. Ask, then move it by hand — not on the engine, even for a couple of yards. - Keep the till receipt. It shows which fuel went in plus about how much, which is the first thing we will ask. If you were still driving when you realised, pull over somewhere sensible rather than pushing on for the services — on the M11, under 50 miles from Great Blakenham, that means the next exit. Stage one follows. ## The fork in every Great Blakenham fuel drain: has it run yet? What comes next rests on one answer, and only one. If it has not once been started: - The petrol is still inside the tank and nowhere else. - Where the vehicle stands is usually where the work is done: a drain, then a flush. - Being here is the best case — which is the whole point of stage one. Motor run, even briefly? - Your lines and your filter now carry petrol drawn from the tank. - Run it further and the petrol reaches the fuel injectors, having passed through the fuel pump first. - Lines flushed, your filter sorted, and sometimes more: the job expands as the mileage does. Petrol does not lubricate. Diesel does, oiling the high-pressure pump and injectors as it flows through, which is why the line falls where it does. A tank of petrol, left alone, hurts nothing. Once it is pumped, petrol begins wearing down whatever moves it. ## What to have ready when you call about petrol in a diesel from Great Blakenham A van that circles versus a technician that finds you: a little planning is the difference. - Where you are. A postcode beginning IP6 0 is the best start. - A road name is a help: Chalk Hill Lane, say, or whichever street you have stopped in. A car park does the trick too. - Car parks are located more easily by what they serve: tell us the one at East of England CO-OP, and it is straightforward. - Tell us what the vehicle is — make, model — and confirm it's diesel. - Tell us which got in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Great Blakenham. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - The miles it covered, and how heavily, if it ran at all. - Whose vehicle it is. Some hire and company agreements want the owner to authorise this work, and that's quicker settled before our engineers get there than after. Call 0333 366 0103 then. Email works as well if it can wait, with your car left at home, going nowhere. ## The wait for a Great Blakenham fuel drain, and what to do in it The wait is where well-intended help does the harm. Hold to these. - Wait with your car if it is safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll the car a couple of yards. - Anything from the boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - No DIY draining. Siphoning petrol into a can by the roadside is hazardous, and it leaves the fuel that has by now gone beyond the tank. - Ignition remains off. Even for your radio or the windows. ## Van arrived? The fuel drain, one step at a time - Three questions. What went in, how much, and whether it's run. Those replies shape the job, which is why the quote comes after them and not before. - Your tank is cleared. The polluted mixture comes out of your tank. - If it ran, your lines are carrying petrol that has moved beyond the tank — so they're cleaned. - Cleared, or swapped if the car has a serviceable one: the fuel filter is dealt with next. - Clean diesel goes in, and your system is primed. - We fire it up only after clean diesel has gone in and primed the fuel system, then check that it's running smoothly. We remain until it is running on fresh diesel. The car goes back to normal driving straight away, and long-term damage is very unusual if it has been spotted early. ## Great Blakenham, after the fuel drain: back on the road - Once it has been started on fresh fuel, there is nothing special to do: drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop then call us a second time. - The work may matter later with a hire firm, an insurer or a fleet manager. Keep the paperwork. - Next time, check the petrol pump. The label, not the colour of its handle. ## About Great Blakenham itself Great Blakenham is a village situated on the riverside in Suffolk, with an elevation of around 17 metres.
