Don't Start It Never turn on your engine. If the petrol is still inside that tank and the motor has not been started, a tank drain is nearly always all it requires — and that gets determined in the next few minutes, not by how much was put in. Petrol in Diesel drains and flushes wrong-fuelled cars where they stand, all over Higher Walton and the rest of Lancashire, on the forecourt, by the roadside or on a drive. Contact us before all else starts, so you will see what happens after that. ## What to do now about petrol in a diesel - Don't crank it. Turned on anyway? Then do not believe it. Diesel in a petrol vehicle generally cannot run, and so the driver stops and the damage ends with them. Petrol in a diesel? It starts. It idles. It drives off normally, for a couple of miles. Motorists get that confused. It's not all right — that fuel system is wearing down every mile you cover. - Leave the ignition alone as well. Diesel has two jobs: it combusts, and before it burns it greases the high-pressure fuel pump and those injectors. Petrol manages the first but not the second. Flicking the ignition on is often enough to prime that system, which carries the petrol out of that tank then into just those parts. - Don't weaken it. Diesel tipped on top gets rid of nothing, and so all you get is more of what was already there, because percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Just petrol. The grade makes no difference. - A motor that has never shifted is the simplest one to sort out, so wait where you are if you reasonably can. Parked on the verge on Hoghton Lane? Hazards on, and keep it there. A tricky spot works for us better than a started motor. - Before you call, gather your whereabouts. Anything closest to you with a name on it, plus a postcode that starts PR5 4 — that's what determines whether our van shows up or circles. - Three details determine the entire job: the fuel you poured in, the ballpark quantity involved, and whether it has been going since. Our number is 0333 366 0103. Petrol in a diesel Renault Megane, sitting at Bamber Bridge since this morning? The afternoon has cost you nothing — fuel sitting in a tank is harmless. It was the trip in that sucked weakened diesel through your pump. Phone us before you collect the vehicle. ## Draining petrol from the diesel on a forecourt A fair portion of the work ends up finished at the pump, because that is where it mostly kicks off. If you are still on the forecourt at Texaco, that is usually where this drain takes place — we work on station forecourts all the time, with the owner's agreement. A forecourt is the only spot the mistake is spotted before your engine has run. The few seconds between seeing your receipt and reaching for the key settle how much requires rinsing. Anywhere other than the forecourt — a car park, a driveway, a lay-by — the car was started and moved to get there, so fuel was pulled from the tank, through your filter and into the high-pressure fuel pump. That means your lines and the fuel filter need cleaning as well as your tank. It's not a calamity, and we can still deal with it where the vehicle sits. Push the vehicle out of the way if the staff volunteer, and they normally will. The next customer gets through the pump, and that's worth doing. Four car lengths isn't worth a start. ## Parts our vans cover around Higher Walton As a village, Higher Walton gets a routine visit, while the areas round about go along on that same trip: School Lane and Coupe Green, Walton Summit and Gregson Lane, Holland Slack. If yours is not on the list that does not mean we never come — there are dedicated pages for the majority of towns in Lancashire, and the ones named above are simply the nearest neighbours. Phone to check rather than presuming — county lines especially, and wherever your phone tends to struggle with. This map shows the patch the page spans. Roadside, forecourt, driveway, car park: every bit of that is ground our engineers work on, and none of it asks your vehicle to travel to us. Put diesel in a petrol vehicle and mostly it will not run, so the person stops there and the damage stops with them. Flip it — petrol into a diesel — and the car fires up, idles and pulls away as though nothing had happened, whilst the high-pressure fuel pump works without the protection your fuel is meant to be supplying. That is the catch, and it is why your diesel Dacia Duster will have felt completely normal coming back from Higher Walton Church of England Primary School. They do. From behind the wheel there's nothing to caution you about, so nothing warns you. Phone us with about how far you travelled, and how hard; the second one matters more than the first. ## Higher Walton: stuck where you pulled up Not everybody has the chance to pull over somewhere sensible. If you worked it out after setting off and finished up by the verge on Blackburn Road, or in a lay-by somewhere with the hazards flashing, that's a normal call for us and not a rare one. Okay right there? Wait beside it. Not okay? Climb out and away from it. Do not start it up to reach a safer location. It'll go — a diesel on petrol normally obliges — and each mile of obliging pulls the mixture deeper into your fuel system. Our van driving to a tricky place is no trouble for us, and it is much better for the car than carrying on. ## A few miles on petrol in a diesel: now what? This is where the Preston Bypass comes in, under a mile from Higher Walton. A misfilled diesel will often take you onto it and some way along before anything feels wrong, and the signs when they arrive are generally a loss of power, a rough idle and smoke rather than a clean stop. Never restart it to reposition. Pull off at the next safe exit and turn off. Long drive? Anything close to the under 3 miles to the closest city and you should suppose the lot — filter, pump, injectors, all of that reached by the contamination. Say that on the phone, since it alters what goes in the van. Here's the entire mechanism. Diesel needs enough body to seal the tight gaps it goes through, and petrol takes that away. That is it. Which explains the ordinary Kathleen Ferrier Memorial Garden call — a diesel BMW 1 Series, out there without a murmur and back down on power, lumpy at idle, maybe a bit of smoke. Injection systems work hydraulically as well as chemically, and so your fuel has to hold pressure and not just burn; weakened, it leaks past those tolerances instead of building, and delivery comes weaker, later, less even than the motor was engineered about. Not a failing engine, though. Fuel that has stopped behaving like diesel. Put that right and it stops. ## A little about Higher Walton Higher Walton is a village in Lancashire, situated on the riverside at an elevation of 31 metres, with terraced housing being the predominant type of accommodation. Higher Walton lies close to the city of Preston, approximately 2.8 miles away, and is near other local places such as School Lane and Coupe Green. Higher Walton has a population of around 1286 residents and is located in the North West region of England, about 186.8 miles from London. ## What follows when we reach you around Higher Walton - We ask first, quote after. What got in? How much? Has the motor run? Those responses change what the work really is. - That tank is drained completely. - Fuel lines are flushed through and your filter cleared, leaving nothing in the fuel system that caused any of this. - Your system gets bled, on fresh diesel. - After it's started, we check it runs correctly on fresh diesel. After that it is ready to pull away. There is no need to go to a garage at any point, since the work is all done where the vehicle is, and when it's spotted quickly, long-term damage is very uncommon. ## AdBlue in your diesel tank by mistake, around Higher Walton? If what got in was AdBlue rather than petrol, the first rule is unchanged — never crank it — yet the problem isn't. Diluted diesel, and no lubrication left for the fuel system that depends on it. That's petrol. AdBlue? Urea dissolved in water. Put that in with your diesel and you get rust instead, plus deposits. Our engineers handle both, and AdBlue removal around Higher Walton has its own page with the detail — including why it's frequently the more serious of the two. The slimmer petrol nozzle fits a current diesel filler neck with practically no resistance at all, which makes this mechanical rather than sloppy. Unfamiliar spots see most of that for that reason. So: fuelled up by Higher Walton Community Centre without thinking, in a diesel Citroen C3 you have had for two days? Phone us where you are. Hire and courtesy cars usually get driven further before anybody spots it, and distance determines how much petrol gets to the fuel injectors. ## Paying for a petrol-in-diesel drain in Higher Walton One price wouldn't be honest here, as this isn't one job. These are the things that shift it: - Started? Driven? Either answer matters more than anything else on this list. - How much of the wrong fuel was put in, against how much your tank takes. - AdBlue or petrol, whichever got in. - Where your car is, and if our van can sensibly get to and work on it. The vehicle, the amount, whether it has run — give us those and the answer comes back clear rather than as a range. Motor at home, going nowhere, nothing time-critical about it — is ideal for that. Drain it then put fresh diesel in — that's the suggestion you'll get, generally from a person certain, and it is only half right. Do precisely that to a diesel Kia Sportage close to Walton-le-Dale Young People's Centre and it would start, which is what makes the advice sound plausible. What occurs next is the trouble: the engine at once draws the petrol still waiting in your filter and the feed lines straight back through your pump, because draining a tank does nothing about fuel that has already left it. Call us instead. Our technicians flush the system and take your filter off where the car has a working one, which is the difference between your car being repaired and the car simply starting. ## Petrol in diesel: everyday questions in Higher Walton ## At a petrol station around Higher Walton, can you do a fuel drain there? Yes, and it's where a big portion of this work gets done. Tell us which one you're at when you phone and we will tell you if our engineers can work there. With the owner's agreement we visit another forecourt nearby and the other forecourts locally routinely. ## A couple of litres of petrol in a diesel — too much? It rests on the proportion instead of the litres, and much more on whether your engine has run. Five litres in a nearly empty tank is a different situation from five in a full one — but either way, the thing that determines how much work is required is if that mixture has been pulled through the system. ## Petrol in my diesel, and I have driven the car Stop somewhere safe, switch off, and keep it off. Driving is what shifts the problem from the tank into your pump and injectors — but it is salvageable much more frequently than motorists expect, and the single most valuable thing you can do now is not restart it. ## Fuel drains and manufacturer warranties It isn't an alteration, and so a drain and flush carried out correctly doesn't void a manufacturer's warranty. Running a diesel on petrol is the thing likelier to cause a dispute with one, which is another good reason to leave the car turned off. ## Can I just add two-stroke oil and drive home? Two-stroke oil solves a different issue, and an old one at that. Nothing it does puts back what petrol thinned. No. That tank still has petrol in it after that, and your pump still has to put up with it. ## Main dealers and petrol in a diesel Wherever the vehicle is, our technicians drain and clean it there, so a trip to the main dealer does not come into it. ## You, and the car, still together? Shut off is the way the car remains. Switch it off somewhere sensible and leave it off, if you have already driven it. Cold, parked, going nowhere: that is the best position to be in. People fear this much more than they need to. Emptying misfilled motors, Higher Walton and the rest of Lancashire, wherever they are. Kerbside. Forecourt. Home.
