Hasn't been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever your car has stopped — and no other factor decides that more than the next few minutes do. What follows is the sequence from here, wherever in Hornsea you happen to be. ## Motor off: minute one with petrol in a diesel Do the following first, in this sequence. - Take your keys out. Even the ignition on its own can prime the system, pulling petrol out of your tank to exactly the parts it harms, so keep the vehicle off wholly. - Do not top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mixture. - Get the vehicle easy to see first — hazard lights on — if there is traffic going past anywhere close to you. - However short the way, starting it to move it is the mistake. At a forecourt, roll the vehicle away from the pump by hand instead, then ask the attendants to lend a hand. - Hold on to the receipt. It says which fuel was put in plus roughly how much, which is the first thing we'll ask. On the M62, under 25 miles from Hornsea, the next junction is the location to come off; anywhere, the first safe place to stop. Do not push on to the services. Then go back to step one. ## Each Hornsea fuel drain starts here: has your motor run? From this stage on, everything hinges on a single answer. Not run, not even briefly: - That petrol is still inside that tank and nowhere else. - A drain and flush, on the spot, is usually all of it. - This is as good as it gets — which is the whole point of stage one. If it has been started, even for a second: - The lines and the filter already carry petrol pulled out of that tank. - The high-pressure pump and the injectors get it on a longer run. - Miles is what turns it into a bigger job: the lines flushed, a filter seen to, and at times more than that. Why the line falls there: diesel protects your high-pressure pump and the fuel injectors as it flows through them, and petrol does not. Nothing is damaged by petrol that is only waiting in a tank. Move the petrol, though, and it wears the very parts doing the moving. ## Hornsea, petrol in a diesel: have these prepared before you call A little preparation is the difference between a van that finds you and a technician that goes round. - Where you are. A postcode beginning HU18 1 is the best place to start. - The street or the car park. A road name helps — Newbegin, or wherever you have stopped. - Describe a car park by what it serves — the one outside Co-op Food, for instance — and it is far quicker to find. - Say what the vehicle is — make, model — and check it's diesel. - Say which was put in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Hornsea. - How much. Litres from the receipt, or how long the nozzle was in the filler. - The distance it did, and how heavily, if it has run at all. - The owner may have to approve the work under some hire and company agreements — which is why it's faster to settle whose motor it is before our engineers get there. Call 0333 366 0103 next. Writing to is fine as well if it can wait, with the vehicle left at home, going nowhere. ## The wait for a Hornsea fuel drain, and what to do in it In the wait, the damage comes from well-intended help — which is why these matter. - Safety before the vehicle. If it has stopped somewhere dangerous, get yourself clear of the traffic then wait away from it. If it's safe where it sits, wait with it. - A kind passer-by doesn't start it. Nor does anybody checking it still works, or rolling it a few yards. - Additives remain in the boot. Injector cleaner and two-stroke oil draw none of the petrol out once more. - A home-made drain leaves the fuel that has already gone beyond that tank, and siphoning petrol by the road is dangerous besides. - Not for your radio, not for your windows: your ignition remains off. ## Van arrived? Your fuel drain, one stage at a time - Three questions. What went in, how much, and whether it has run. Those replies set the job, which is why our quote comes after them and not before. - Draining it is how the blend gets taken from your tank. - Petrol that has moved beyond your tank travels in the lines if it ran, and the lines are flushed to clear it. - Cleaned, or replaced if the car has a workable one: your filter is seen to next. - Bleeding your system follows after clean diesel is in. - Starting it. When your system is primed with clean diesel, our technicians start it and make sure it runs correctly. The car has fresh diesel running through it before our engineers head off. If it has been spotted early, long-term damage is very rare, and the vehicle goes back to normal driving right away. ## Hornsea, after your fuel drain: back on the road - Drive normally. There's nothing special to do once it has been started on fresh fuel. - Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot. - Your paperwork covers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - The handle's colour isn't the guide to go by next time — the label on the petrol pump is. ## About Hornsea, briefly Hornsea is a coastal town in the East Riding of Yorkshire, situated approximately 13 miles south-east of Kingston upon Hull.
