Stop there. Petrol in a diesel that has not been run is usually a drain and a flush, done right where your car stands, and what happens in the next few minutes determines that more than anything else. Wherever you are around Tobermore, this is the order things go from now. ## Petrol in a diesel, engine off — the first minute Before anything else, these — in this sequence. - Take your keys out. Even your ignition by itself can prime the fuel system, pulling petrol out of your tank to exactly the components it harms, and so leave it off entirely. - No diesel on top. More fuel in takes away none of that petrol — it only leaves you with extra of the same mixture. - Being seen comes before the rest beside moving traffic: switch your hazards on, and only then deal with everything else. - Off the petrol pump by hand. On a forecourt, ask the staff to help you push the car away from the petrol pump. Don't fire it up to move it, however short the way. - Keep your receipt: the grade and roughly how much are printed on it, and they're what our engineers ask for first. Noticed on the move? Get off at the next exit if you are on the M77, over 50 miles from Tobermore, and pull over somewhere safe — not at the services farther on. Stage one starts after that. ## Each Tobermore fuel drain starts here: has your motor run? What happens after this turns on one answer, and just one. Not run, not even briefly: - Only that tank has petrol in it for now. - A drain and flush, on the spot, is usually all of that. - This is as good as it gets — which is the whole point of stage one. Engine run, even briefly? - From that tank, through your filter, into the lines: that's how far that petrol has travelled. - Run it further and the petrol gets to your injectors, having passed through your pump first. - Lines flushed, your filter seen to, and sometimes more: the job expands as the distance does. The line falls there because diesel protects your high-pressure pump and the fuel injectors on its way through them — and petrol does not. A tank of petrol, left still, damages nothing. Once it's pumped, petrol begins wearing whatever moves it. ## Calling about petrol in a diesel from Tobermore: what to have ready Get ready a little, and the technician finds you rather than circling. - Your whereabouts: a postcode starting BT45 5 serves best. - The road or the car park. A road name helps — B842, or wherever you have pulled up. - What a car park serves is the easiest way to find it, and so say the landmark — such as the one outside the local shops. - That it is a diesel, plus the make and model of your vehicle. - Which went in counts: AdBlue is a separate job from petrol, plus Tobermore has a page just for that. So tell us. - How much. Litres from your receipt, or how long the nozzle was in. - The miles it covered, and how hard, if it ran at all. - Hire or company car? Some agreements need the owner's go-ahead for this work, and getting it before we get there is faster than afterwards. Phone 0333 366 0103 once you have got that ready — or, if the car is at home, going nowhere, use . ## The wait for a Tobermore fuel drain, and what to do in it Stick to these: well-meant help does the harm during the wait. - Safety before the vehicle. If it has stopped somewhere exposed, get yourself clear of the traffic and wait away from it. If it's safe where it is, wait with it. - No one — however kind — starts it, whether to see if it runs or to shift the vehicle a short way. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol. - A DIY drain leaves your fuel already gone beyond that tank, and siphoning petrol by the road is dangerous too. - Not for your radio, not for your windows: the ignition stays off. ## Step by step: your fuel drain when our van arrives - Fuel, amount, whether it has run: the answers set this job, and that is why you get a quote after them rather than before. - Then the tank is cleared, so the contaminated fuel is taken out. - The fuel lines are purged. If it ran, that petrol has moved beyond your tank, and the lines are carrying it. - Where the car has a serviceable filter, it is replaced; otherwise, cleared. - Fresh diesel in, and your system primed. - First start on fresh diesel. Once bleeding is done, your engine is started and we make sure that it runs smoothly. Only when it is running on fresh diesel do our engineers go. The car goes back to normal driving straight away, and permanent damage is very uncommon if it has been spotted soon. ## Tobermore, after your fuel drain: back on the road - Once it's been started on fresh fuel, there is nothing special to do: drive normally. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your signal to stop and call us a second time. - Keep 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 the handle. ## About Tobermore, for a moment Tobermore is a small locality in County Londonderry, situated inland at an elevation of 52 metres.
