Stop; leave the car off. Emptied and flushed, just where it sits: that is usually all an unrun diesel with petrol in it needs. Whether it stays that straightforward rests on the minutes ahead more than on anything else. Anywhere you happen to be around Hawick, this is the order things go from here. ## Motor off: minute one with petrol in a diesel In this order, and before anything else: - Bleeding the fuel system draws petrol from your tank toward the parts it damages, and turning the ignition on can be all it takes to do that. So the keys get taken out, and the ignition remains off completely. - A fuller tank of the same mix is all topping up leaves you, since it takes out nothing. So no extra diesel. - Make the car simple to see before anything else — hazard lights on — if there is traffic going past anywhere close to you. - However short the distance, starting it to shift it is the thing to avoid. At a forecourt, push the car away from the petrol pump by hand instead, then ask the staff to lend a hand. - Hold on to the till receipt: the grade and roughly how much are printed on it, and they're what our technicians ask for first. If you were still on the move when you realised, pull over somewhere safe rather than pushing on for the services — on the A74(M), under 50 miles from Hawick, that means the next exit. Step one comes next. ## Every Hawick fuel drain starts here: has the motor run? From this point on, everything comes down to a single answer. If it has not once been started: - Just the tank has petrol in it for now. - The work is a simple drain and a flush, usually done where the car stands. - This is the best place to be in, and the whole reason stage one counts. Motor run, even briefly? - Out of your tank, through your filter, into the fuel lines: that is how far the petrol has travelled. - Run it farther and the petrol gets to your injectors, having passed through your fuel pump first. - The further it went, the larger this job — the lines, the filter, and sometimes more besides. Diesel keeps the high-pressure pump and the fuel injectors oiled as it goes through them. Petrol gives them nothing, and that's why the line is drawn there. Petrol sitting in a tank damages nothing. Pump that petrol, though, and it grinds down the very parts doing the moving. ## Before you call about petrol in a diesel around Hawick: what our technicians need A van that circles against a technician that finds you: a little planning is the difference. - Your whereabouts: a postcode starting TD9 9 serves best. - A road name is a help: Duke Street, say, or whichever street you have stopped in. A car park does the trick too. - Or the nearest landmark. A car park is quicker to find by what it serves, like the one at Aldi. - The make and model of your car, and the fact it is a diesel. - Which went in matters: AdBlue is a separate job from petrol, and Hawick has a page just for that. So say. - How much. Litres from your receipt, or how long the nozzle was in. - If it's run, how far and how heavily — and whether it's run at all. - The owner may have to approve this work under some hire or company agreements — which is why it is quicker to settle whose car it is before we get there. Then call 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## Waiting for a fuel drain in Hawick: what to do Stick to these: kindly meant help does the harm during the wait. - Where the vehicle has stopped settles where you wait. Somewhere exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of the vehicle. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a few yards. - Additives stay in the boot. Injector cleaner and two-stroke oil take none of that petrol out a second time. - No home-made emptying. Siphoning petrol into a can by the kerbside is dangerous, and it leaves your fuel that has already gone beyond that tank. - Even the radio or the windows are not worth switching your ignition on for. ## Van arrived? Your fuel drain, one step at a time - First, three queries: which fuel went in, the amount, and has it run? Those replies decide the job, and so our quote follows them. - That tank is drained. The tainted mixture comes from that tank. - Petrol that has moved beyond your tank sits in the fuel lines once it ran, and the lines are purged to clear it. - The filter is seen to. Cleared, or swapped where the car has a workable one. - The system is primed on clean diesel. - Our technicians fire it up only after clean diesel has gone in and bled your system, then make sure that it's running smoothly. Only when it is running on clean diesel do our engineers leave. It's very unusual for a vehicle spotted quickly to be left with long-term damage, and normal use resumes right away. ## Back on the road around Hawick after the fuel drain - Started on clean diesel, it asks nothing unusual of you. Simply drive normally. - Pull over and ring us back if anything looks wrong early on — a light on the dash, smoke from the exhaust, an idle that is lumpy, or a throttle with a dead spot. - Hold on to your documents. A hire company, a fleet manager or an insurer may ask what was done. - Check the label on the petrol pump next time, not the colour of the handle. ## About Hawick, briefly Hawick is a town situated in a picturesque riverside location within the Scottish Borders.
