The coming few minutes decide it more than anything else: petrol in a diesel still unrun generally comes down to draining and cleaning, on the spot. Here is the sequence of things from here, anywhere you are around Frogmore. ## Petrol in a diesel? What to do in minute one Do the following first, in this sequence. - Priming the fuel system pulls petrol from the tank towards the parts it harms, and switching your ignition on can be all it takes to do that. So the keys come out, and the ignition stays off altogether. - Do not top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture. - Get the vehicle simple to see first — hazard lights on — if there is moving traffic anywhere close to you. - The attendants will generally help you push it clear of the pump. Let them, and roll it by hand — never under the engine, even for a couple of yards. - Hold on to the receipt: the grade and the rough amount are written on it, and they're what our technicians ask for first. If you were still driving when you noticed, pull over somewhere sensible instead of pushing on for the services — on the M3, under 3 miles from Frogmore, that means the next junction. Stage one comes next. ## Each Frogmore fuel drain starts here: has the motor run? Everything after this stage rests on one answer. Motor not run at all? - All the petrol sits inside your tank, and only there. - The job is a simple drain and a flush, usually done where the car stands. - No spot is better, and it is why the first stage counts so much. Run at all, even for a second: - Petrol has been drawn out of the tank, through the filter then into the fuel lines. - On a longer run it has reached the high-pressure pump as well as the fuel injectors. - The job expands with the distance — lines flushed, filter seen to, occasionally more. Diesel keeps your high-pressure pump and the injectors oiled as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. In the tank, left alone, petrol does no harm. Once it is pumped, petrol begins wearing whatever moves it. ## What to have ready when you call about petrol in a diesel from Frogmore A little preparation is the difference between a technician that finds you and a van that circles. - GU17 0 and the rest of the postcode makes the ideal way to begin telling us where you are. - Wherever you have parked, the road's name is useful — whether that is Hartley Close or somewhere else — and so does the name of a car park. - Car parks are located most easily by what they serve: tell us the one outside Aldi, and it is simple. - The make and model of the vehicle, and the fact it is a diesel. - Say which was put in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Frogmore. - The quantity: your receipt's litres, or otherwise how long you held the nozzle in. - Whether it has run. And if it has, how far and how hard. - Hire or company car? Some agreements want the owner's go-ahead for the work, and sorting it before our technicians get there is quicker than after. Next, 0333 366 0103. Not time-critical, your car left at home with nowhere to be? Then works as well. ## Frogmore fuel drain on its way? Whilst you wait Stick to these: well-meant help does the damage during the wait. - Your safety comes before the vehicle. Somewhere unsafe? Get clear of the traffic and wait away from it. Fine where it sits? Wait with it. - Not to roll it a few yards, not to check it is all right, not as a passer-by's favour: no one starts it. - Additives remain in the boot. Injector cleaner and two-stroke oil take none of the petrol out again. - A DIY drain leaves your fuel that has already gone beyond that tank, and siphoning petrol by the road is hazardous besides. - Keep the ignition off — the windows and the radio included. ## When our van arrives: the fuel drain, step by step - Our price comes after three queries, not before them — what went in, how much, and whether it has run — because those replies shape this job. - Your tank is cleared. The contaminated mixture comes out of your tank. - Your lines are cleaned. If it ran, that petrol has shifted beyond your tank, and your lines are carrying it. - Then the fuel filter: swapped where there's a usable one, cleared where there's not. - Priming follows once fresh diesel is in. - The first start on clean diesel. Once bleeding is finished, the motor is fired up and our engineers confirm that it runs correctly. Our engineers stay until it's running on clean diesel. If it has been spotted early, lasting damage is very rare, and the vehicle returns to normal use straight away. ## After your fuel drain is done: driving in Frogmore again - Nothing special is needed after a start with fresh diesel — ordinary driving will do. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over and ring us back. - Hold on to your paperwork. A hire firm, a fleet manager or an insurer may ask what was carried out. - Read the label on the petrol pump next time, not the colour of its handle. ## About Frogmore Frogmore is a suburban area in Hampshire, situated on the riverside with an elevation of around 64 metres.
