Pause; leave the vehicle off. The next few minutes settle it far more than anything else: petrol in a diesel still unrun generally comes down to draining then flushing, on the spot. From now on, in order, for anywhere around Upper Street: ## Petrol in a diesel, motor off — the first minute Do these first, in this order. - Take the keys out. Even the ignition on its own can prime the system, drawing petrol out of the tank to exactly the components it damages, and so keep it off wholly. - Topping up with diesel seems like it dilutes the issue. It does not: nothing gets out, and that tank simply holds more of the same. - Visibility comes first beside moving traffic: put your hazards on, and only then deal with anything else. - Off the pump by hand. At a forecourt, ask the staff to help you roll the vehicle away from the pump. Don't start the vehicle to move it, however short the distance. - Which fuel, and roughly how much? Your receipt replies that, and that is where our first question starts. Do not bin it. Still on the move when you realised? Come off the M11 at the next junction if that's where you are, over 50 miles from Upper Street, and pull over somewhere sensible instead of pushing on to the services. Then begin at stage one. ## Has it run yet? The fork in every Upper Street fuel drain From this point on, everything comes down to a single answer. If the engine has not run at all: - The petrol is still inside that tank and nowhere else. - Where the car stands is usually where this work happens: a drain, then a flush. - This is as good as it gets — which is the entire point of step one. Run at all, however briefly: - The fuel lines and the filter now hold petrol drawn out of the tank. - Run it further and the petrol gets to the fuel injectors, having passed through the fuel pump first. - Flushing the lines, your filter seen to, and sometimes more: this job expands as the miles does. Diesel keeps your high-pressure pump and the injectors lubricated as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. Nothing is harmed by petrol that's only resting in a tank. Move the petrol, though, and it wears the very parts that move it. ## Upper Street, petrol in a diesel: have these prepared before you call A little planning is the difference between a technician that finds you and a technician that goes round. - Where you are. A postcode beginning NR11 8 is the ideal place to start. - Wherever you have parked, the road's name helps — whether that's High Street or somewhere else — and so does the name of a car park. - What a car park serves is the quickest way to find it, so mention the landmark — such as the one outside Tesco Express. - That it is a diesel, plus the make and model of your vehicle. - Say which was put in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Upper Street. - Roughly how much — in litres from your receipt, or by how long the nozzle was in. - Whether it's run. Then if it has, how far plus how hard. - The owner may have to authorise the work under some hire or company contracts — which is why it is faster to settle whose car it is before we arrive. Then call 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — does the trick too. ## The wait for a Upper Street fuel drain, and what to do in it Help, however well meant, is what does the harm whilst you wait. So stick to these. - Where the vehicle has stopped settles where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety before the car. - A kind passer-by doesn't fire it up. Nor does anyone wanting to check it still does the trick, or moving it a couple of yards. - Additives stay in your boot. Injector cleaner and two-stroke oil draw none of that petrol out again. - Siphoning petrol into a can by the kerbside is risky — and it still leaves whatever fuel has already gone beyond that tank. Don't drain it yourself. - Even your radio or the windows aren't worth turning the ignition on for. ## When the van arrives: the fuel drain, step by step - Our quote comes after three questions, not before them — what was put in, how much, and whether it's run — because those answers decide this job. - Clearing it is how the mixture gets taken from your tank. - The lines are rinsed. If it ran, that petrol has shifted beyond the tank, and your lines are holding it. - Cleaned, or swapped if your car has a serviceable one: the filter is sorted next. - Clean diesel in, and your system primed. - First start on fresh diesel. Once priming is complete, your engine is started and we make sure that it runs properly. The car has clean diesel running through it before we head off. The vehicle returns to normal use right away, and permanent damage is very unusual when it has been spotted soon. ## Back on the road around Upper Street after your fuel drain - Nothing special is needed after a start with clean diesel — normal driving is all. - Pull over and ring us back if anything looks wrong early on — a light on the dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - Hold on to the documents. A hire firm, a fleet manager or an insurer may ask what was done. - Check the label on the pump next time, not the colour of its handle. ## About Upper Street and where it is Upper Street is a small suburban area in Norfolk, situated near the coast and approximately 17.5 miles from Norwich.
