If you have not fired up the motor yet, don't. A fuel drain and nothing else is nearly always what a motor needs while the fuel is still inside the tank and the engine has not yet been started, which is why it's the next few minutes that count, not how much was put in. Petrol in Diesel comes to the car wherever it has ended up in Branchton or the rest of Inverclyde, on the forecourt, at the roadside or on a driveway, and drains and flushes it there. Phone and then our technicians will explain what happens from here before you try any more. ## What to do first about petrol in a diesel - Give a petrol engine diesel and it will generally refuse to run at all, and so the motorist stops there and so does the harm. Feed a diesel petrol and the thing starts, it idles, it drives off — fine for a couple of miles. Most people have that muddled, which is the part they get wrong about petrol in a diesel specifically. So don't start it. And once started, never depend on it: that fuel system is wearing down while you drive. - Flicking the ignition on frequently primes that system, and priming is what pulls petrol out of that tank then into the pump and injectors. Those are the components diesel keeps greased on its way through, before it burns. Petrol does the burning and none of the oiling. Leave the car's ignition off. - Do not tip diesel on top to water down it. A diesel fuel system will not tolerate petrol by percentage as that advice presumes, and topping up clears nothing — it merely hands you a larger tank of the same blend. The octane makes no difference either: super unleaded is just petrol. - We'd rather get to a difficult spot than have it started — so if you safely can, stay put. Nothing is quicker to sort than a motor that hasn't moved. On the verge on Kirkwall Road, that means hazards on then keep the car. - Have your whereabouts ready before you dial. A postcode beginning PA16 0 and whatever is nearest to you with a name on it is the difference between the van showing up and the van circling. - Call 0333 366 0103. Expect three points — what was put in, roughly how many litres, and if the car has been started. The answers settle all that happens next. Quarter past eight. A rushed top-up on the drive in. At about eleven it occurs to you, and by then your diesel Renault Megane has stood at the nearest station for three hours. Phone us then keep it where it stands. What is key is the run in, as diesel both combusts and — before that — lubricates the pump and the injectors, whereas petrol only ever burns. Those few miles ran your pump on a fuel robbed of most of its protection, and no volume of standing in a car park gives any of it back. Hence the question about distance rather than hours standing, and hence the instruction to leave the keys where they are until our engineers arrive. ## Clearing petrol from a diesel at a forecourt Pumps are where this job mostly starts, and where a good part of that closes. The drain typically happens there and then. Still on the forecourt at BP? Given the station's consent, that's a place our engineers work, and routinely. Nowhere else except a garage can the mistake be spotted with your engine still unrun. Everywhere else — a car park, a drive, a lay-by — the vehicle was started and moved to get there, which means fuel was sucked from your tank, through your filter and into your high-pressure pump. That's not a disaster, and we can still sort it out where it sits. It does mean the fuel lines and the filter need cleaning as well as your tank, and that is determined by the few seconds between seeing your receipt and going for your key. The staff will usually happily wheel the vehicle away from the pump so the next driver can get by. It is worth doing. Four vehicle lengths is not worth the risk. The complicated part is that bay, not the fuel. Motors either side of you, a trolley shelter behind, and now and then a height bar on the way in that decides if a technician can get to you at all — so when you call from a car park like the one outside Co-op Food, say how much space there's around you and which way round the vehicle is. Those our technicians cover regularly. Should there be no space to work alongside the diesel Volkswagen Passat, it gets rolled with the engine off, and not out of fuss over a few seconds of running: priming occurs at every start, more of the blend departs your tank for the pump, and two shunts into a nicer bay have quietly made a harder job of what was simply a motor standing still. ## Will we cover your side of Branchton? Branchton is a residential suburb, so our vans get out to it and to the villages near it on the same journeys: Fancy Farm, Smithston, Ravenscraig, Spango and Braeside. We do come. The names above are just the immediate neighbours, and a page is there for most places across Inverclyde, so an absence from the list is not an absence from the coverage. Near the boundary, or anywhere your phone misreads? Call us and enquire rather than presuming. The map shows the ground this page spans. The car doesn't need to move to us. We work across every bit of it — roadside, forecourts, driveways, car parks. ## Stranded by the roadside around Branchton Not everyone gets the chance to pull in somewhere suitable. If you realised after setting off and landed on the verge on Stromness Place, or in a lay-by somewhere with your hazards going, that's a normal call for us instead of an unusual one. Wait with the vehicle when it is safe to wait in it, yet out of it if it is not. Every mile a diesel obliges you for on petrol pulls that mix further into the fuel system — and oblige it often will, which is why the motor does not get restarted to limp somewhere handier. Carrying on does the vehicle far more harm than our van heading out to an inconvenient location, and that is no problem for us. Your Mercedes C-Class stays where it is in the car park outside The Burns Lounge for the whole job, which typically goes like this. First we ask what got in, about how much, and whether the motor has run since, because much of the work rests on those answers. That tank is emptied of the tainted mix, the fuel lines are flushed, and the filter comes off if it's a replaceable one. With new diesel in and your system primed, your car is started and checked, and once it's running correctly you pull away. ## So you've run it? Petrol in a diesel after a few miles This is where your M8 comes into it — under 10 miles away from Branchton. It will often get you onto it, and some way along, before you feel a thing. Then it is some smoke, a lumpy idle and power ebbing away — not a neat stop. Misfilled diesels rarely give you one of those. Don't restart it to reposition. Come off at the next safe exit and switch off. Long drive? Anything approaching the under 25 miles to the nearest city and you should assume the lot — filter, pump, injectors, all of that arrived at by the petrol. Say that on the call, as it affects what goes in the van. ## A bit about Branchton Branchton is a coastal suburban area in Inverclyde, situated near the towns of Fancy Farm and Smithston, with Ravenscraig to the east. Branchton sits at an elevation of 88 metres, overlooking the coastal landscape of the Clyde estuary. Branchton has a mix of housing types, but semi-detached homes are the most common, reflecting the area's residential character. Branchton is located approximately 22 miles west of Glasgow, Scotland's largest city. ## When our technicians get to you in Branchton: what happens - We establish what got in, how much, and whether your engine has run. The responses shape the work, which is why our technicians ask before giving a price. - Away flows the tainted mixture. - Our engineers clean your fuel lines and clean the filter, so what's remaining in the system isn't what started the issue. - Priming follows, once new diesel is in. - Once it is turned on, our technicians make sure it runs smoothly on new diesel. That leaves your car ready to drive away. Everything is done where the vehicle is, so it never has to go to a garage, and when it has been spotted early, permanent damage is very rare. Why so direct about leaving the keys alone? Since your pump is before the fuel injectors, and a worn one sends whatever it loses on with the fuel. Call us. Leave the BMW 5 Series near Ravenscraig Stadium. ## AdBlue in your diesel tank by mistake, in Branchton? Do not fire it up: that opening instruction stands whether what went in was AdBlue or petrol. What changes is the problem itself. The lubrication a fuel system relies on is stripped away by petrol, which dilutes your diesel. Corrosion and residue are what a diesel tank ends up with instead, because AdBlue is urea dissolved in water. We deal with both, and AdBlue removal in Branchton has its own page with the details — including why it is usually the more significant of the two. A throttle gone soft, white smoke, a lumpy idle, knocking: that's a misfilled diesel Citroen C3 telling you what's wrong. Do not restart the vehicle to find a better spot — switch off where you have stopped, close to St. Andrew's Parish Church or anywhere else. ## Budgeting for a petrol-in-diesel drain in Branchton What changes the price is listed below, because the job is not one job and our technicians can't frankly put a single price on this page. - Started? Driven? Either answer counts more than anything else on this list. - The tank's capacity, set against how much of the wrong fuel went into it. - AdBlue or petrol, whichever was put in. - Where your car is, and whether our van can safely get to and work on it. Tell us what the vehicle is, how much got in, and whether your engine has run. A clear answer comes back, not a range. For the car at home that's going nowhere and is not urgent, works too. ## Branchton motorists ask us these about petrol in diesel ## Can you do a fuel drain at a petrol station in Branchton? Much of what we do happens nowhere else. So yes. Routinely, provided the site consents: Tesco, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our engineers can work in that place is something our engineers answer on the spot. ## A couple of litres of petrol in a diesel — too much? Litres aren't the measure. Ratio is, and much more than either, it matters if anything has been run. Five litres in a nearly empty tank is a different case from five in a full one — but either way, the thing that determines how much work is required is whether that mix has been pulled through the fuel system. ## Petrol in my diesel, and I have driven the vehicle Turn off somewhere sensible, then keep it that way after you stop. Driving is what shifts the issue from that tank into your pump and injectors — but it's salvageable much more regularly than motorists expect, and the single most helpful thing you can do now is not restart the car. ## Will a fuel drain void my warranty? A drain then flush carried out properly isn't a change and doesn't void a manufacturer's warranty. Another good reason to leave it switched off: running a diesel on petrol is the thing more likely to cause an argument with one. ## Can I just add two-stroke oil and drive home? No. Two-stroke oil is an old workaround for a different fault and it does not put back what petrol has diluted. The pump still has to put up with it, since the tank still has petrol in it later on. ## Do I need a main dealer for petrol in a diesel? There's no need to take it to a franchised dealer, since we drain and clean the vehicle wherever it is. ## Still with the vehicle? Leave the car shut off. Turn it off somewhere sensible and keep it off, if you have already driven it. Cold, stationary, going nowhere: that's the best position to be in. People fear this far more than they need to. Call-out fuel draining in Branchton and throughout Inverclyde — at the roadside, on the forecourt or at home.
