Here Is What Happens Whatever you do, never switch your motor on, even for a moment, to move the car. Pause; leave the car off. Hasn't been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever your car has stopped — and nothing decides that as much as the next few minutes do. Below is the sequence from here, wherever in Luton you happen to be. ## Petrol in a diesel? What to do in minute one Go through these in sequence, before you do anything else. - Take your keys out. Even your ignition on its own can prime the fuel system, drawing petrol out of your tank to exactly the components it harms, and so leave the car alone wholly. - A bigger tank of the same mix is all topping up gives you, since it takes out nothing. So no more diesel. - Hazards on. If you're anywhere near moving traffic, make your car simple to see before you do anything else. - However short the distance, starting it to shift it is the mistake. At a forecourt, roll the car clear of the petrol pump by hand instead, and ask the staff to lend a hand. - Which fuel, and roughly how much? Your receipt replies both, and that is where our first question starts. Don't throw it away. Still driving when you realised? Come off the M1 at the next exit if that is where you are, under 3 miles from Luton, and pull over somewhere sensible rather than pushing on to the services. Then start at step one. ## Has it run yet? The fork in each Luton fuel drain From this point on, everything comes down to a single answer. If it has not once been started: - No place but your tank: that is where that petrol yet is. - Where your car sits is normally where this work is done: a drain, then a flush. - This is the best place to be in, and the whole reason stage one counts. Engine run, even for a moment? - Petrol has been drawn from the tank, past the fuel filter and into your lines. - On a longer run it has reached your high-pressure pump and the fuel injectors. - The further it went, the larger the job — the lines, the fuel filter, and sometimes more besides. The reason the line falls there: diesel protects the high-pressure pump as well as the injectors as it flows through them, and petrol doesn't. Nothing is harmed by petrol that's just waiting in a tank. Once it's pumped, petrol begins wearing down whatever moves it. ## What to have ready when you call about petrol in a diesel from Luton Prepare a little, and the van finds you instead of circling. - Your location: a postcode beginning LU1 2 works best. - A road name is a help: George Street, say, or whichever street you have stopped in. A car park works too. - Car parks are located more easily by what they serve: tell us the one outside VS Food & Wine, and it's easy. - The make and model of the car, and the fact it's a diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has its own Luton page. - The amount: the receipt's litres, or otherwise how long you had the nozzle in. - The mileage it covered, and how hard, if it ran at all. - Whose motor it is. Some hire and company agreements want the owner to approve the work, and that is quicker settled before our technicians get there than after. Ring 0333 366 0103 once you've got that ready — or, if the car is at home, going nowhere, use . ## Waiting for a fuel drain in Luton: what to do Stick to these: kindly meant help causes the harm during the wait. - Where the vehicle has stopped decides where you wait. Exposed: away from it, away from the traffic. Safe: with it. Either way, safety ahead of your car. - Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll the vehicle a few yards. - None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives. - No DIY emptying. Siphoning petrol into a can by the kerbside is dangerous, and it leaves your fuel that has already gone beyond that tank. - Leave the ignition off — the windows and the radio too. ## The fuel drain, step by step, once our van gets there - Fuel, amount, whether it's run: the answers decide this job, and that is why you get a quote after them instead of before. - Out of the tank comes the polluted blend: the tank is emptied. - If it ran, the lines are carrying petrol that has shifted beyond the tank — so they are purged. - Then your filter: replaced where there's a usable one, cleared where there is not. - Priming follows once fresh diesel is in. - Starting the car. Once the fuel system is primed with fresh diesel, we start it and make sure it runs smoothly. The vehicle has clean diesel running through it before we go. If it has been spotted quickly, long-term damage is very unusual, and the vehicle goes back to normal driving at once. ## After the fuel drain: back on the road in Luton - Drive normally. There is nothing unusual to do once it's been started on fresh fuel. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop then call us a second time. - An insurer, a fleet manager or a hire company may ask what was done, and so hold on to the paperwork. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Luton itself Luton is a significant urban centre situated in the county of Bedfordshire, England.
