Don't Start It Do not fire up your engine. While the fuel is still sitting in the tank and your engine has not been started, a fuel drain is nearly always all it takes — and that gets decided in the next few minutes, not by how much was put in. Petrol in Diesel drains and flushes misfuelled cars where they sit, throughout Pikes Hill and the rest of Hampshire, on the forecourt, at the roadside or on a drive. Our technicians can show you what the next part will be. Phone — this goes ahead of anything else. ## What to try first about petrol in a diesel - Do not start the car — and do not trust it if it runs. Here is the part motorists get wrong about petrol in a diesel in particular. A petrol motor filled with diesel usually just will not run, and so the driver stops and the wear halts with them. A diesel given petrol generally starts, idles and moves off perfectly well for a couple of miles. It is not fine. It is eating into your fuel system while you drive. - Turning the car's ignition on often primes that system, and priming is what moves petrol out of your tank and into your pump and injectors. Those are the components diesel keeps oiled on its way through, before it burns. Petrol manages the burning and none of the protecting. Leave your ignition off. - Do not tip diesel on top to thin it. A diesel fuel system does not accept petrol by percentage as that advice presumes, and topping up takes out nothing — it simply leaves you a bigger tank of the same blend. The type makes no difference either: super unleaded is just petrol. - A car that hasn't shifted is the easiest one to sort out, so remain where you are if you safely can. Pulled up on the verge on Pikes Hill? Hazards on, then leave it there. A difficult location works for us better than a started engine. - Our van showing up instead of circling turns on two things: a postcode starting SO43 7, and whatever is closest to you with a label on it. Keep both ready before you dial. - Dial 0333 366 0103. Tell us what was put in, approximately how much, plus if the motor has started. These three facts shape your whole visit. ## Can petrol be taken from a diesel at a forecourt? Much of this work starts at a pump, which means a fair chunk of that gets finished there. If you are still at the forecourt at Esso, that's typically where this drain gets done — our technicians work on petrol station forecourts routinely, with the owner's consent. No place but the forecourt can this be halted with your engine still untouched. Everywhere else — a car park, a driveway, a lay-by — the car was switched on and driven to get there, which means fuel was sucked from your tank, through the filter then into your high-pressure pump. That's not a catastrophe, and our engineers can still put it right where it is. It does mean the fuel lines and the filter need rinsing as well as your tank, and that's settled by the few seconds between checking your receipt and going for the key. Move it out of the way if the attendants suggest it, and they usually will. The next motorist gets by the pump, and that is worth doing. Firing it to shift four vehicle lengths isn't. We are in car parks like the one outside Morrisons a lot, and it is hardly ever your fuel that complicates them. It is that bay. Motors both sides. Trolleys stacked up behind. At times a height bar at the entrance, which settles if our van gets to you at all. So say how penned in you are when you phone, and which way the vehicle is facing. If there is no space to work next to your BMW 3 Series, our technicians roll it without the engine. That isn't fuss over a handful of seconds: starts prime things, mixture comes out of that tank towards the pump, and a motor moved twice for a better spot is quietly a worse job than one nobody touched. ## Can we serve your end of Pikes Hill? Pikes Hill is a residential suburb, and so our vans get out to the town and to the areas near it on the usual trips: Custards, Lyndhurst, Emery Down, Goose Green and Bank. Our technicians still come. Those places above are just the nearest neighbours, and a page exists for most towns around Hampshire, so an absence from the list isn't an absence from our coverage. Phone and ask instead of guessing — borders above all, and wherever your phone may misread. This map outlines the area the page includes. Our technicians work by the road, on forecourts, on driveways and at car parks across all of that, and the car doesn't need to move to us. Every restart primes the fuel lines and drags more petrol through your filter and into the pump. So a wrongly fuelled diesel Nissan Qashqai on the zig-zags outside St Michael and All Angels CofE Infant School is an inconvenience, while the same car restarted three more times to be polite is a fuel system instead of a tank. Somebody will urge you to shift the vehicle out of that gateway and sort it out later. Don't. Leave it there, let everyone complain, then give us a call. ## Roadside stops around Pikes Hill Some drivers find no suitable spot to pull over whatsoever. If you noticed after setting off and ended up by the verge of Westwood Road, or in a lay-by somewhere with the hazards flashing, that's a routine call for us instead of an odd one. Wait by your car while it is safe to be in it, but clear of the car if it's not. Don't start it up to get to a better spot. It'll go — a diesel on petrol generally obliges — and each mile of obliging pulls that mix deeper into the fuel system. Driving on causes the car far more harm than a technician driving out to an awkward place, and that is no bother for us. What our technicians will want to know is whether the run there was brief and cold, since that's where petrol is slowest to burn fully — and whatever does not burn can slip past the piston rings then into the engine oil. Right up to the moment someone takes it home, a diesel Mercedes C-Class parked in the car park at Waterloo Arms with a tank full of petrol in it is a straightforward job. Nothing degrades whilst it waits, so park the car overnight and phone next morning. ## A few miles on petrol in a diesel: what next? Here is where your M27 matters, under 3 miles away from Pikes Hill. Some way along, and onto it in the first place: a misfilled diesel will frequently do both before anything feels wrong. What you get then is seldom a tidy stop. Power ebbs away, the idle gets uneven, and there may be smoke. Take the first junction that is safe, stop there, and do not start it to reposition. Suppose the worst of it on a long drive. Anything close to the under 10 miles to the nearest city, and the contamination has been through your filter, through the pump, through the fuel injectors. Mention it when you phone. What our technicians bring changes. The pump is not turning, and so whatever the diesel Audi A3 did on the way to Foldsgate Inclosure, none of it is happening now. Nothing gets worse while it sits. Take your time over this — but don't drive the car home to buy any. ## A little about Pikes Hill Pikes Hill is a suburban area in Hampshire, situated near the riverside and close to the New Forest. Pikes Hill has a relatively low elevation of 48 metres and is located near several nearby places, including Custards, Lyndhurst, and Emery Down. Pikes Hill is characterized by its predominantly detached housing stock and is home to a population of around 802 residents. Pikes Hill is also within commuting distance to major cities, with Southampton just 7.9 miles away and London approximately 76.5 miles distant. ## Once our engineers reach you around Pikes Hill: what happens - Three things get checked before any price — the fuel that went in, the amount, and whether anything has been run since. Each answer changes the work. - Out comes the tainted fuel. - What is remaining in the fuel system should not be what started the trouble, and so the lines get cleaned and the fuel filter cleaned. - Our technicians pour new diesel in and bleed the system. - It's run with fresh diesel in it, and we confirm that it's running correctly. From that point, you're ready to drive away. Our technicians do everything wherever the vehicle has stopped, which means it never needs to be taken to a workshop, and if it has been spotted soon, it is very unusual for there to be lasting damage. Draining the Ford Kuga, changing the fuel filter where there is a serviceable one, purging your lines, putting fresh fuel through the full system: that's the job, and it is shaped by the worst of it waiting in your lines instead of in that tank by this point. Three things help when you ring from near Northerwood House — which side the filler is on, whether a van can stand alongside without blocking the road, and if the motor has run since you filled up. On-street is the usual spot our engineers work, and so the spot itself is seldom the problem. A narrow parking spot trumps a car driven somewhere more convenient. ## Pikes Hill AdBlue removal is a different job AdBlue instead of petrol? Then the first instruction is unchanged — the engine stays off — while this problem beneath it's a different one altogether. The lubrication a fuel system relies on is taken away by petrol, which thins your diesel. AdBlue is urea dissolved in water, and in a diesel tank it leads to corrosion and residue instead. Both are ours. There's a separate Pikes Hill page for AdBlue removal, with the details on it — including the reasons it often turns out to be the worse of the two. ## How much is a petrol-in-diesel drain in Pikes Hill? One price wouldn't be fair here, as this isn't one job. These are the things that change it: - Started? Driven? Either answer counts more than anything else on this list. - Wrong fuel in, against what the tank holds — that proportion. - Whether it was petrol or AdBlue. - Whether a technician can sensibly get to your car and work on it, which hinges on where your vehicle is. A firm answer instead of a range is what you get for telling us three things: your car, the quantity, and whether it has run. Not time-critical, with the car at home and going nowhere? Then works. ## Petrol in diesel: common queries in Pikes Hill ## Can you do a fuel drain at a petrol station around Pikes Hill? Yes, and it is where a fair share of this work happens. We attend Texaco and the other forecourts around town regularly, with the site's agreement — tell us which one you are at when you phone and we'll tell you whether our engineers can work there. ## How much petrol in a diesel is too much? It depends on the ratio instead of the litres, and much more on whether the motor has run. What decides how much work is required is whether that mixture has been pulled through the fuel system — because although five litres in an almost empty tank is a different situation from five in a full one, either way that's the question. ## I put petrol in my diesel and drove it. What next? Pull in somewhere sensible, turn off, and leave the car off. Not restarting it is the single most valuable thing available to you now. Driving does shift the trouble out of that tank then into the pump and injectors, yes, and it stays fixable much more frequently than motorists fear. ## My warranty — does a fuel drain void it? It isn't a change, so a drain and flush carried out properly does not void a manufacturer's warranty. What's likelier to start an argument is a diesel that has been run on petrol. One more reason for the motor to remain off. ## Two-stroke oil in your tank, and then home? What petrol has diluted isn't replaced by two-stroke oil, which is an old workaround for a different problem. So no. Petrol stays in that tank later on, whatever else goes in, and your pump gets no reprieve from it. ## Does petrol in a diesel have to go to a main dealer? You do not need one. The vehicle is drained and cleaned wherever it is, with no need to take it to a dealership. ## You, and your car, still together? The motor remains off. Switch it off somewhere safe and keep it off, if you have already driven it. This is recoverable from much more frequently than drivers fear, and a still, cold car is the best position to be in. Call-out fuel draining in Pikes Hill and across Hampshire — at the roadside, on the forecourt or at home.
