Motor off. Keep the car like that — no second on, no shifting it at all. Cleared and flushed, right where it is: that is generally all an unrun diesel with petrol in it needs. Whether it remains that simple depends on the minutes to come more than on anything else. Here is the sequence of things from now, wherever you are in Old Drumchapel. ## Engine off: minute one with petrol in a diesel In this sequence, all before anything else: - Pull your keys out. Even your ignition by itself can prime the system, drawing petrol out of your tank to precisely the parts it harms, so keep it alone completely. - Do not top it up with diesel. Adding diesel takes out nothing. You are left with a fuller tank of the same mixture. - Being seen comes before the rest beside moving traffic: put the hazard lights on, and only then deal with anything else. - Off the pump by hand. At a forecourt, get the staff to help you roll the car clear of the pump. Do not fire it up to shift it, however short the way. - Hold on to the receipt. It says which fuel got in plus about how much, which is the first thing we will ask. Still driving when you noticed? Come off the M8 at the next junction if that's where you are, under 3 miles from Old Drumchapel, and stop somewhere sensible rather than pushing on to the services. Then begin at stage one. ## Old Drumchapel fuel drain: has the engine run yet, or not? From this point on, everything hinges on a single answer. If your motor hasn't run at all: - That petrol is still in that tank and nowhere else. - The work is a simple drain and a flush, normally done where the car is. - Stage one counts for precisely this reason: it is the best place to be in. Run at all, even for a second: - Some petrol has left the tank already, gone through the fuel filter, and reached the fuel lines. - Your high-pressure pump as well as the injectors get it on a longer run. - The further it went, the larger this job — the lines, the fuel filter, and sometimes more besides. That line falls there because diesel lubricates your high-pressure pump and the fuel injectors on its way through them — and petrol does not. In your tank, sitting still, petrol does no harm. The components that move it are grinding the moment petrol is being pumped. ## Calling about petrol in a diesel from Old Drumchapel: what to have ready A little planning is the difference between a technician that finds you and a van that goes round. - Where you are. A postcode starting G15 6 is the ideal place to start. - The road or the car park. A road name helps — Firdon Crescent, or wherever you have pulled up. - Car parks are found more easily by what they serve: say the one at Aldi, and it's simple. - Say what your car is — make, model — and check it is diesel. - Tell us which got in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Old Drumchapel. - How long the nozzle was in, or the litres from your receipt — either gives us how much. - Has it run? If so, say how far it got, and how it was driven. - Whose motor it is. Some hire or company contracts want the owner to approve the work, and that's easier settled before our engineers arrive than after. Ring 0333 366 0103 once you have got that together — or, if your car is at home, going nowhere, use . ## Old Drumchapel fuel drain on its way? Whilst you wait The wait is where kindly meant help does the damage. Stick to these. - Wait with your car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - A helpful passer-by does not start it. Nor does anybody checking it still works, or moving it a few yards. - No additives. Two-stroke oil, injector cleaner, something from the boot — none of it takes that petrol back out. - A home-made drain misses the fuel already gone beyond your tank, and siphoning petrol by the road is dangerous besides. - Leave your ignition off — the windows and the radio too. ## Van arrived? Your fuel drain, one stage at a time - Three questions. What went in, how much, and if it's run. The replies set this job, which is why the price comes after them and not before. - That tank is emptied. The polluted blend comes from that tank. - The fuel lines are cleaned. If it ran, the petrol has moved beyond that tank, and your lines are holding it. - Where your car has a workable filter, it's replaced; otherwise, cleared. - Clean diesel goes in, and the fuel system is primed. - Our engineers fire it up only after fresh diesel has gone in and bled your system, then make sure that it's running properly. Your car has fresh diesel running through it before our engineers leave. The vehicle goes back to normal use right away, and lasting damage is very rare if it has been caught quickly. ## Old Drumchapel, after your fuel drain: back on the road - Started on fresh diesel, it needs nothing unusual of you. Just drive normally. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over and call us back. - The paperwork covers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - The handle's colour is not the guide to go by next time — the label on the petrol pump is. ## About Old Drumchapel, briefly Old Drumchapel is a suburban area situated on the River Clyde, with a mix of residential and local amenities, and is located near the neighbouring areas of Blairdardie, Drumchapel, and Linnvale.
