The first thing to do is not to start your engine. While the engine has not run and the petrol is still sitting in that tank, a fuel drain is almost always all it requires, and the next few minutes determine that, not how much got in. One call to us will be enough: our team can tell you what happens after this. Make this right away. ## What now? Petrol in a diesel, step by step - Feed a petrol motor diesel and it will typically refuse to run at all, and so the motorist stops there and so does the wear. Give a diesel petrol and the thing starts, it idles, it moves off — all right for several miles. People have that reversed, which is the bit they get wrong about petrol in a diesel in particular. So do not fire it up. And having started, do not trust it: that fuel system is wearing as you drive. - Leave your ignition be also. Diesel does two roles: it burns, and before it ignites it protects the injection pump and those injectors. Petrol does the first and not the second. Turning the ignition on is often all it takes to prime your system, which draws this petrol out of that tank and into exactly those parts. - Topping up removes nothing. It gives you a fuller tank of the same mixture, since a diesel fuel system won't accept petrol by percentage in the way that guidance suggests — so don't add diesel on top to water down it. Type is beside the point too: super unleaded is petrol. - A vehicle that has never shifted is the quickest one to sort out, and so wait where you are if you sensibly can. Stopped on the verge on Fletchwood Lane? Hazards on, then leave the car there. A tricky place suits us better than a started motor. - A van showing up rather than circling hinges on two things: a postcode that starts SO40 7, and whatever is next to you with a sign on it. Get both ready before you phone. - Ring 0333 366 0103. Say what got in, approximately how much, plus whether the motor has fired. These three answers shape the full job. ## Can petrol be pumped from a diesel at the forecourt? Most of this work begins at the pump, so a big share of it gets completed on site. Still at Morrisons? Then that's generally where it gets done. Petrol station forecourts are everyday for us, with the agreement of the site. At the forecourt, this is caught with your engine never started, and no place else manages it. Everywhere else — a car park, a driveway, a lay-by — your car was started and moved to get there, which means fuel was drawn from the tank, through the filter then into your high-pressure pump. That's not a calamity, and we can still deal with it where it stands. It does mean your lines and your filter need cleaning as well as that tank, and that's decided by the few seconds between reading your receipt and reaching for the key. Clear of the petrol pump, the next customer can get past — so yes, let the attendants help you roll the vehicle. Worth doing. Starting it just to shift four car lengths is not. ## Parts our team reach in Ashurst Bridge These same rounds carry us to Netley Marsh, Foxhills, Rushington, Hammonds Green and Colbury along with Ashurst Bridge, which is a coastal village. Not on that list? That means nothing. The names above are simply the nearest few, and the majority of locations across Hampshire have a page of their own elsewhere on our site. Ring us and ask rather than assuming — county lines particularly, and anywhere a satnav may struggle with. The patch the page includes sits on this map. Roadside, forecourt, drive, car park: the lot is ground we cover, and none of that requires your vehicle to come to us. Hazards on. Ignition off. Ring us. It's twenty to nine at the gates of Hazel Wood Infant School, you are late, and your receipt reads unleaded — and though three miles in the BMW 3 Series seems like nothing, fuel is metered to demand, and a frantic dash demands plenty of it. ## Stopped by the kerbside anywhere in Ashurst Bridge? Some people find no sensible place to stop at all. Hazards going in a lay-by somewhere, or stopped on the verge beside Ashurst Bridge Road since you noticed after setting off — our engineers take that call so often that it's the normal kind. Whether you stay beside the motor or keep clear of it rests on whether staying nearby is safe. Don't fire up the engine to nurse it somewhere handier — a diesel running on petrol will usually oblige, and every mile it obliges for is dragging that blend further into the fuel system. A van driving to an awkward spot is no trouble for us, and it is much better for your car than driving on. Simple job, this one — until somebody drives it home. A diesel Peugeot 308 left at White Horse with petrol in the tank loses nothing by standing there overnight, and so park the car and call us once it's light. Expect a question about the trip there, though. Brief and cold is exactly where petrol battles to burn, and what will not burn can work past the piston rings and into the oil. ## A couple of miles on petrol in a diesel: now what? Here is where the local Nursling Spur Motorway comes into it — under 3 miles away from Ashurst Bridge. It will usually get you onto it, and some way along, before you spot a thing. Then it is some smoke, a rough idle and power ebbing away — not a neat stop. Wrongly fuelled diesels seldom give you one of those. The next sensible exit is the one to take. Turn off there, then leave the restarting alone. It alters what we bring, and so tell us when you ring: on a longer drive — anything approaching the under 10 miles to the nearest city — assume the petrol has been through your filter, the pump and the injectors. Fine on the way out, flat on the way back. If that is how that trip to Lower Larches went, that tank is where to look. Petrol thins diesel, and weaker fuel slips past the tightly fitted parts that are supposed to build injection pressure — so the further your Mercedes E-Class travelled, the less well it held that pressure. Stop somewhere sensible, switch off then call us. ## Where is Ashurst Bridge? Ashurst Bridge is a small village in Hampshire, situated near the coast and close to the cities of Southampton and Portsmouth. Ashurst Bridge has a low elevation of around 12 metres above sea level and is surrounded by nearby places such as Netley Marsh and Foxhills. Ashurst Bridge is characterized by its predominantly detached housing stock and is located approximately 72.9 miles from London. Ashurst Bridge remains a quiet residential community with a population of around 639 people. ## The visit in Ashurst Bridge, step by step - We find out what got in, how much, and if the motor has run. The responses change the work, which is why we ask before quoting. - Away goes the tainted fuel. - What is left in the system shouldn't be what started the issue, and so your fuel lines get cleaned and your filter cleared. - Your system gets bled, on fresh diesel. - It is fired up with clean diesel in it, and we make sure that it is running correctly. That has your car ready to pull away. There is no need for a garage at any point, as the work is all done where your car is, and when it is noticed soon, long-term damage is very unusual. ## AdBlue in a diesel tank around Ashurst Bridge is a different job AdBlue rather than petrol? Then the first rule is unchanged — the motor remains off — whereas this issue beneath it's a distinct one altogether. The protection a fuel system depends on gets stripped away by petrol, which dilutes the diesel. Urea in water, AdBlue, and in a diesel tank that leads to corrosion and build-up. Both are ours. There is a separate Ashurst Bridge page for AdBlue removal, with the detail on it — including the reasons it often turns out to be the worse of the two. Authorisation first, where there's a hire firm or a company behind the car — some agreements demand it, and settling that beforehand saves a great deal of time later. After that, phone us about the diesel Seat Leon close to West Totton Centre. You'll not know how full that tank was. Barely anyone does, two days into a car, and it gets worked out on site anyway. We ask because the damage petrol does in a diesel is proportional: a couple of litres in an almost empty tank make a much stronger blend than the same few in a full one, and since petrol is engineered to resist igniting under pressure, which is exactly what a diesel relies on, the stronger it gets the more the motor rattles and smokes and flattens off. ## Ashurst Bridge prices for a petrol-in-diesel drain Frankly, no single price belongs on a page like this. This job varies. Here is what moves it: - Whether the engine has been run or driven. This is the big one. - The tank's capacity, set against how much of the wrong fuel went into it. - Whether it's petrol or AdBlue. - Where the car is, and if a technician can sensibly get to and work on it. The car, the amount, whether it has run — give us those and the answer comes back straight and not as a range. Motor at home, going nowhere, nothing pressing about it — is fine for that. By now that tank is the least of that. Run a diesel and that mix goes into the filter, into the lines, into the pump, into the rail — and none of that leaves with the tank contents. A diesel Vauxhall Corsa that made it close to St. Matthews wants its system cleared. Emptying is not the same thing. ## Petrol in diesel questions from Ashurst Bridge drivers ## Can you do a fuel drain at a petrol station in Ashurst Bridge? Yes — forecourts are where a large portion of this takes place. Tell us which one you are at when you call and we'll tell you if our engineers can work there. With the site's consent our technicians visit Esso and the other forecourts around town all the time. ## How much petrol is too much for a diesel? It hinges on the ratio instead of the litres, and a lot more on whether your engine has run. An almost empty tank with five litres in it, against a full one with the same five: distinct scenarios, definitely. Either way, the work needed comes down to one thing, which is if the fuel system has had that mixture pulled through it. ## I drove it after putting petrol in my diesel. Now what? Switch off somewhere sensible, and keep it that way after you stop. Driving shifts the issue along — out of the tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one really helpful thing left to you is not restarting the vehicle. ## Will a fuel drain void my warranty? A manufacturer's warranty outlasts a drain then flush done to a proper standard, which is no change at all. What's likelier to start a disagreement is a diesel that has been run on petrol. One more good reason for your engine to remain off. ## Adding two-stroke oil, then driving home No. Two-stroke oil is an old workaround for a separate fault and it does not replace what petrol has diluted. Petrol stays in that tank later, whatever else goes in, and your pump gets no respite from it. ## Main dealers and petrol in a diesel No. Our technicians drain and flush the car wherever it is, so there is no need to bring it to a main dealer. ## You, and the car, still together? Never switch the car back on. Driven it already? Then somewhere sensible, stop, turn off, and no restarting the car later. This is recoverable from far more often than drivers expect, and a parked, cold vehicle is the best place to be in. At the kerbside, on the forecourt or at home — on-site fuel draining around Ashurst Bridge and across Hampshire.
