Here Is What Happens Stop. Engine off. Keep the vehicle that way — no moment on, no shifting it at all. The next few minutes determine it far more than anything else: petrol in a diesel that has not run usually comes down to clearing then cleaning, right there. From here on, in order, for anywhere around Gibraltar: ## Engine off: minute one with petrol in a diesel In this order, and before everything else: - The ignition off, keys out. Turned on, the ignition can prime your system — and priming is what moves petrol out of your tank into the components it harms. - Don't top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mix. - Make your car simple to see first — hazards on — if there's traffic going past anywhere close to you. - The attendants will usually help you push it clear of the petrol pump. Ask, and move it by hand — never under the motor, even for a couple of yards. - Keep your receipt. It shows which fuel was put in plus about how much, which is the first thing we will ask. Noticed on the move? Get off at the next junction if you're on the M1, under 10 miles from Gibraltar, and stop somewhere sensible — not at the services further on. Stage one starts after that. ## The fork in every Gibraltar fuel drain: has it run yet? One answer is what everything after this stage rests on. Motor not run at all? - The petrol sits inside your tank, and just there. - Usually it's emptied and rinsed just where your car is. - Step one counts for precisely this reason: it's the best spot to be in. Engine run, even for a moment? - Petrol has been pulled out of the tank, past your filter and into the fuel lines. - Run it farther and the petrol gets to the fuel injectors, having passed through your fuel pump first. - The further it went, the bigger the job — the fuel lines, the filter, and sometimes more besides. The line falls there because diesel protects your high-pressure pump and your injectors on its way through them — and petrol doesn't. Petrol resting in a tank damages nothing. The components that shift it are grinding the moment petrol is being pumped. ## What to have prepared when you call about petrol in a diesel from Gibraltar Get ready a little, and the technician finds you rather than circling. - MK43 9 and the rest of the postcode is the ideal way to start telling us where you are. - Wherever you have pulled up, the road's name is useful — whether that is Home Road or somewhere else — and so does the name of a car park. - Car parks are located more easily by what they serve: tell us the one outside Lidl, and it's simple. - That it is a diesel, plus the make and model of the vehicle. - Tell us which went in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Gibraltar. - How much. Litres from your receipt, or how long the nozzle was in. - Whether it's run. And if it has, how far plus how hard. - Sort who has the vehicle ahead of when we turn up: some hire and company contracts want the owner to authorise this work, and that is faster first. Then ring 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick as well. ## Gibraltar fuel drain on its way? While you wait Hold to these: well-intended help causes the damage during the wait. - Your safety comes before the vehicle. Somewhere dangerous? Get away from the traffic then wait away from it. Safe where it is? Wait with it. - Nobody — however helpful — starts it, whether to see if it runs or to move your car a short way. - Additives remain in your boot. Injector cleaner and two-stroke oil take none of the petrol out once more. - A DIY drain leaves the fuel that has already gone beyond that tank, and siphoning petrol by the road is risky besides. - Keep your ignition off — the windows and your radio included. ## When the van gets there: the fuel drain, step by step - Fuel, volume, whether it's run: those answers decide the job, and that's why you get a quote after them instead of before. - Your tank is drained. The polluted mixture comes out of your tank. - Petrol that has shifted beyond that tank travels in the lines once it ran, and the lines are purged to shift it. - Where the vehicle has a workable filter, it's replaced; if not, cleared. - The system is primed with clean diesel. - We start the car only after fresh diesel has gone in and bled the system, then make sure that it is running correctly. The car has clean diesel running through it before our technicians go. It is very rare for a vehicle caught quickly to be left with lasting damage, and normal driving resumes straight away. ## After your fuel drain is done: driving around Gibraltar once more - Once it's been started on fresh fuel, there is nothing unusual to do: drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop then ring us again. - The work may come up 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 the handle. ## About Gibraltar Gibraltar is a small village in Bedfordshire, situated inland at an elevation of 41 metres, approximately 45 miles north of London.
