A drain and nothing else is nearly always what a vehicle needs while the fuel is still sitting in the tank and your engine has not turned over, which is why it's the next few minutes that count, not how much was put in. Petrol in Diesel travels to your car wherever it has stopped in Little Ann or the rest of Hampshire, on the forecourt, by the roadside or on a private drive, and drains and cleans it there. We will explain what the next step will be. Phone — this happens ahead of anything else. ## Your first five minutes: petrol in a diesel - Don't crank it. Started regardless? Then do not believe it. Diesel in a petrol vehicle normally cannot run, and so the driver stops and the wear ends with them. Petrol in a diesel? It starts. It ticks over. It moves off normally, for a few miles. Drivers get that reversed. It is not fine — that fuel system is wearing down every mile you cover. - Diesel combusts, and before it ignites it greases — that injection pump, those injectors. Petrol does only the burning. So leave your ignition off as well: turning it on is commonly sufficient to prime your system, and priming moves petrol from the tank into precisely those components. - Don't water down it. Diesel poured on top gets rid of nothing, so all you have is more of what was already there, because percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Just petrol. The octane makes no difference. - A vehicle that has never moved is the simplest one to handle, and so wait where you are if you reasonably can. Pulled up on the verge on Little Ann Road? Hazards on, and leave the vehicle there. An odd location works for us better than a started motor. - Before you ring, get your position. Anything next to you with a name on it, plus a postcode beginning SP11 7 — that's what settles whether the van shows up or circles. - Three details determine the entire call-out: the liquid you poured in, the ballpark measure of it, and if it has been turning since. The line is 0333 366 0103. Quarter past eight, a hurried top-up on the road in, and you realise close to eleven — by which time the diesel Volkswagen Golf has been left outside Andover for three hours. Call us then leave the vehicle just where it is. The run in is the part that counts here, because diesel has two jobs on its way through the engine: it combusts, and before it burns it greases the high-pressure pump and the injectors. Petrol does the first and not the second. So those couple of miles were driven with your pump working on a liquid that had shed a great deal of the protection it is designed around — which is why the thing our technicians ask is how many miles you travelled, not how long your car has been parked. ## On the forecourt: draining petrol from a diesel Forecourts are where the work often kicks off, and where a big portion of that ends. If you're still on the forecourt at Shell, that's typically where this drain happens — we work on petrol station forecourts regularly, with the owner's permission. Before the engine has run — the forecourt is the one location this gets stopped. Fuel drawn out of that tank and through the filter, all the way to the high-pressure pump, is what occurs when your engine is fired up and the car is moved to where it is now: the car park, the driveway or the lay-by, anywhere other than the forecourt. So the flush includes the fuel filter and the lines as well as the tank. That is still not a catastrophe, and we put it right where the car is. What settles it is whether the key was turned in the seconds after the till receipt was checked. The staff will usually happily roll the vehicle clear of the petrol pump so the next motorist can get through. It is worth doing. Four car lengths isn't worth a restart. Car parks like the one outside McColls are somewhere our technicians work in regularly, and the fuel is rarely the awkward part. That bay is: cars either side, a trolley shelter behind, sometimes a height barrier on the way in that determines if a van can get to you at all. So tell us how hemmed in you are when you phone, and which way the vehicle is facing. When we can't work beside the diesel Renault Megane we'll shift it without running it — and that isn't fussiness about a few seconds of running. Any start primes your fuel system and sucks more of the mixture out of your tank and on to the pump, so a motor shuffled twice into a better spot has silently grown into a bigger job than one left precisely where it stopped. ## Coverage around Little Ann As a residential suburb, Little Ann gets a steady visit, whilst its neighbours nearby come along on the same round: Abbotts Ann and Bulbery, Anna Valley and Red Rice, Upper Clatford. There are dedicated pages for the majority of towns across Hampshire, and the ones named above are simply the nearest neighbours — so yours being absent from the list means nothing whatsoever about if our engineers come. Ring us and ask instead of presuming, above all where you're on a border or anywhere your phone gets wrong. That map outlines the patch the page covers. The car never needs to travel to us. We work across every bit of that — roadside, forecourts, driveways, car parks. ## Stranded by the kerbside around Little Ann Not everybody gets a safe place to stop. A normal call for us and not a rare one: noticed after setting off, finished up by the verge of Saint Mary's Meadow or at a lay-by with your hazards flashing. Whether you sit by your car or keep clear of it hangs on if being there looks wise. Never fire up the motor to limp it somewhere safer — a diesel running on petrol will often oblige, and every mile it obliges for is pulling that mix further into the fuel system. We'll send our van to an inconvenient spot without any trouble, and for the car that's much better than carrying on. Straightforward job, this one — till someone takes it home. A diesel Nissan Qashqai sitting by The Poplar Farm Inn with petrol in the tank loses nothing by standing there overnight, so park it and ring us once it is light. Expect a query about the drive there, though. Brief and cold is exactly where petrol fails to burn, and what will not burn can slip past the rings and into the engine oil. ## Petrol in a diesel, and your car has travelled This is where the M3 matters, under 15 miles out of Little Ann. It will often take you onto it, and some way along, before you spot a thing. Then it's smoke, an uneven idle and power falling away — not a clean stop. Misfuelled diesels rarely give you one of those. Take the first junction that is sensible, pull up there, and don't start it to move it. Long drive? Anything close to the under 15 miles to the closest city and you should presume the lot — filter, pump, injectors, all of that arrived at by the contamination. Say that on the call, since it changes what goes in our van. ## About Little Ann Little Ann is a suburban area situated on the riverside in Hampshire, with a relatively low elevation of 59 metres. Little Ann lies near the city of Winchester, approximately 12.8 miles away, and is also close to nearby places such as Abbotts Ann and Anna Valley. Little Ann has a population of around 947 people and predominantly features detached housing. ## What our engineers do when our engineers get to you around Little Ann - The answers alter the work, which is why our technicians ask before giving a price: what went in, how much of it, and if your motor has run. - Your tank is drained of everything. - We flush the fuel lines and clean the fuel filter, so what's left in the fuel system is not what started the trouble. - Priming follows, once fresh diesel is in. - Our engineers fire it up and make sure it runs smoothly on fresh diesel. Then it's ready to pull away. There is no need to go to a garage at any point, since the work is all done where the car is, and when it's spotted soon, permanent damage is very rare. ## Little Ann AdBlue removal is a different job The fault isn't the same, though the opening step is — never start it — if what was put in was AdBlue rather than petrol. The protection a fuel system relies on is taken away by petrol, which weakens your diesel. Rust and build-up are what a diesel tank gets instead, as AdBlue is urea dissolved in water. AdBlue removal around Little Ann has a page of its own with the detail on it, including why it is often the more significant of the two. We cover both. Petrol in a diesel does its damage as a proportion, which is the reason we ask at all: the same few litres resting in a nearly empty tank make a far stronger blend than they would in a full one. And petrol is rated on how well it withstands igniting under pressure — the opposite of what a diesel wants — so a stronger mixture knocks more, smokes more, goes flatter. None of which means you need an answer prepared. Nearly nobody knows how full the tank was in a car collected two days ago, and our engineers work that out on site. Do call the hire or company firm first, though: some agreements want them to sign off the work, and that is far faster settled before than after. Then phone us about the Kia Sportage near Bury Hill Fort. ## What a petrol-in-diesel drain will cost around Little Ann Honestly, no single number fits on a page like this. The job changes. Here's what moves it: - Whether your engine has been run or driven. This is the main one. - Wrong fuel in, against what the tank holds — that ratio. - The kind of fluid in the tank, petrol or AdBlue. - Where your car is, and if a van can safely get to and work on it. Tell us the car, the amount and if it has run, and you'll get a clear answer instead of a range. Not pressing, with your car at home and going nowhere? Then does this job. That softness is your fuel failing to build pressure correctly, not the engine packing up — and with no warning for it, cars in that position generally get driven a second time before somebody rings. Do not. A few streets is all it got: throttle gone limp, idle turned uneven, and a diesel Ford Fiesta now sitting near Squash courts. Turn the car off then phone us. ## Questions our engineers hear about petrol in diesel around Little Ann ## I am on a forecourt in Little Ann. Can you drain the car on the spot? Much of what we do takes place nowhere else. So yes. Permission from the site is the condition. Given that, a forecourt like BP is somewhere we are regularly, along with the rest of them locally — so name yours on the call and you will hear if working there is possible. ## Is there a sensible quantity of petrol in a diesel? Whether the engine has run counts far more, though the ratio matters too, rather than the litres. Five litres in an almost empty tank is a separate matter from five in a full one — but either way, the thing that determines how much work is required is whether that mixture has been sucked through the fuel system. ## Petrol in my diesel, and I have driven the car Somewhere sensible, then stop, then turn off and keep it off. Driving takes the issue along — out of that tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one genuinely useful thing left to you is not restarting the car. ## Is a fuel drain going to void my warranty? No. Carried out correctly, clearing and purging is no modification at all, and the warranty from your manufacturer is untouched by it. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a disagreement with one. ## Can I just add two-stroke oil and drive home? What petrol has weakened isn't restored by two-stroke oil, which is an old remedy for a different problem. So no. Afterwards? Still petrol in your tank, and a pump that has to cope with the stuff. ## A main dealer for petrol in a diesel — essential? You don't need one. The vehicle is drained and flushed wherever it is, with no need to take it to a dealership. ## Standing next to it? Do not switch it back on. Already driven it? Then pull in somewhere sensible, turn off, and let it stay that way. This is recoverable from a lot more commonly than motorists expect, and a stationary, cold car is the best position to be in. At the roadside, on the forecourt or at home — call-out fuel draining around Little Ann and throughout Hampshire.
