Don't Start It Petrol in Diesel drains and cleans misfuelled cars where they sit, on the forecourt, by the roadside or on a private drive, throughout West Wittering and the remainder of West Sussex. The very first thing to do is not to start your engine. When the engine has not yet turned over and the fuel is still in your tank, a drain is nearly always all it needs, and the coming few minutes determine that, not how much got in. Our technicians will show you what the following move is. Contact us — it happens ahead of all else. ## Petrol in a diesel: what to try now - Never start the vehicle — and do not believe it when it runs. This is the part drivers have wrong about petrol in a diesel especially. A petrol engine given diesel typically just won't run, so the motorist stops and the harm halts with them. A diesel filled with petrol typically starts, idles and moves off perfectly well for several miles. It's not all right. It's wearing out the fuel system while you drive. - Leave your ignition off too. Diesel does two roles: it ignites, and before it combusts it protects that high-pressure fuel pump and those injectors. Petrol does the first and not the second. Switching the ignition on is commonly enough to prime your system, which draws that petrol out of that tank and into just those parts. - Never dilute it. Diesel added on top takes out nothing, so all you get is more of what was already there, because percentage is not how a diesel fuel system tolerates petrol. Super unleaded? Just petrol. The octane makes no difference. - We would much rather travel to a difficult place than have it started — so if you safely can, sit tight. Nothing is simpler to sort out than a motor that has not moved. On the verge on Elms Lane, that means hazards on and leave the car. - Get your location ready before you phone. A postcode beginning PO20 8 and whatever is next to you with a label on it is the difference between the van turning up and the van circling. - Call 0333 366 0103. Anticipate three points — what was put in, about how many litres, plus whether your car has been turned over. The responses determine whatever follows. Do not take it home. The commute has already sent a real load of petrol-thinned diesel through your high-pressure pump of your Renault Clio, and the drive back would roughly double it for no gain at all. Ring us from the platform if that's handier. Our engineers never need you hovering over the vehicle outside Nutbourne whilst our technicians get it done, and we'd far rather hear from you tonight than find out on Monday. ## At the forecourt: draining petrol from the diesel Plenty of this job begins at a forecourt, which means a big chunk of it is done on site. The drain typically gets done right there. Still on the forecourt at Shell? Given the owner's agreement, that is a spot our engineers work, and routinely. A forecourt is the one setting it gets halted before your engine has started. The few seconds between seeing the receipt and going for the keys settle how much needs cleaning. Everywhere other than a forecourt — a car park, a private drive, a lay-by — your car was fired up and driven to get there, so fuel was sucked from that tank, through the fuel filter and into your high-pressure pump. That means the lines and the filter require rinsing as well as the tank. It is not a disaster, and we can still deal with it where your car stands. Staff will usually help out pushing it away from the petrol pump, which lets the next customer get by. Welcome the offer. Four car lengths isn't worth the risk. The call our technicians like sounds like this: diesel BMW 3 Series, a few litres of unleaded, done a couple of miles, now turned off outside Co-op Food. What we are truly asking is how much fuel your pump has pulled — not how long ago it was. ## West Wittering and the towns beside it As a coastal village, West Wittering sees a routine call, and the areas nearby come with it on the same run: Rookwood and East Wittering, Shipton Green and West Itchenor, Somerley. Not on this list? That means nothing. The places above are only the closest few, and the majority of places around West Sussex have a page of their own somewhere on the site. Phone to enquire instead of presuming, particularly where you're on a boundary or anywhere a satnav misreads. Use our map for the area included on this page. The car doesn't need to move to us. We operate over all of it — kerbside, forecourts, driveways, car parks. A diesel pump meters fuel to demand, and a rushed morning dash needs plenty — so three miles in your Peugeot 308 feels like nothing and isn't. Twenty to nine by West Wittering Parochial Church of England School, running late, a receipt in your hand showing unleaded: hazards on, engine off, phone us. ## Kerbside breakdowns across West Wittering The chance to pull in somewhere suitable does not come to everybody. Set off, then noticed? Finished up by the verge of Elmstead Gardens, or stuck in some lay-by with your hazards going? That's a routine call here. Not an odd one. Okay right there? Sit beside it. Not safe? Move out and clear of it. Every mile a diesel obliges you for on petrol draws that blend further into the system — and oblige it often will, which is why your motor doesn't get restarted to limp somewhere better. However difficult the place, it is no problem for us to come to it, and that is far better for your car than driving on. ## A couple of miles on petrol in a diesel: what now? under 10 miles out of West Wittering, the local Waterlooville Bypass is what matters now. A misfilled diesel will frequently get you onto it and some distance along before anything seems wrong, and the symptoms when they appear are generally a loss of power, a rough idle and some smoke rather than a clean stop. Pull off at the next safe exit, turn off, and never start it to move it. Suppose the worst of it on a long run. Anything close to the under 10 miles to the nearest city, and the petrol has been through your filter, through your pump, through the fuel injectors. Tell us when you ring. What we bring alters. Injection pressure is the part being lost. Petrol thins diesel, and weaker fuel slips past the close-fitting components that are meant to build that pressure, so the farther a diesel Ford Kuga went, the less well it held. Fine on the way out and flat on the way back is how the run to Wittering Football Club went, then, and the tank is the place to look. Pull in somewhere sensible, switch off and call us. ## West Wittering itself West Wittering is a small coastal village in West Sussex, situated on the Manhood Peninsula near the city of Chichester. West Wittering has a low elevation of around 6 metres above sea level and is surrounded by other nearby places such as Rookwood and East Wittering. West Wittering is characterised by its predominantly detached housing stock and is located approximately 60 miles from London. West Wittering remains a quiet residential community with a population of around 823 people. ## What comes next when our engineers get to you in West Wittering - Our technicians find out what got in, how much, and whether your engine has run. The responses change the work, which is why our technicians ask before quoting. - The tainted fuel is drawn out of the tank. - What is remaining in the fuel system should not be what caused the issue, and so the lines get cleaned and the fuel filter cleaned. - Clean diesel goes in, and then the system gets primed. - It is started with fresh diesel in it, and we make sure that it is running correctly. Then it's ready to pull away. Everything is done where the car is, so it never has to be taken to a garage, and when it has been caught quickly, long-term damage is very unusual. ## AdBlue in the diesel tank instead, in West Wittering? Don't start it: that first instruction holds whether what was put in was AdBlue or petrol. What differs is this issue itself. Petrol does two things to diesel: thins it, and strips out the protection the system depends on. Urea in water, AdBlue, and in a diesel tank that leads to rust and build-up. Both are ours. There is a separate West Wittering page for AdBlue removal, with the full story on it — including the reasons it frequently turns out to be the worse of the two. Clattering? Ragged idle? White smoke, throttle gone soft? That's your wrongly fuelled Volvo XC60, a diesel, saying what is wrong with it. Stop wherever you happen to be, perhaps by Sir Henry Royce, and leave the restarting alone. ## West Wittering pricing for a petrol-in-diesel drain Our engineers can't put one price on this page frankly, as the job is not one job. What changes it: - Whether your motor 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. - Which was put in: unleaded or AdBlue. - Where the car is, and if a van can sensibly get to and work on it. A firm answer rather than a range is what you get for telling us three things: the vehicle, the quantity, and whether it has run. Motor at home, going nowhere, nothing urgent about it — is good for that. ## Petrol in diesel: common questions around West Wittering ## Can you do a fuel drain at a petrol station around West Wittering? A big part of this work happens there, so yes. Often, provided the site agrees: JET, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether we can work in that location is something we answer there and then. ## How much petrol in a diesel is too much? It hinges on the ratio instead of the litres, and far more on whether the motor has run. What settles how much work is needed is if that mix has been drawn through the fuel system — because although five litres in a nearly empty tank is a distinct matter from five in a full one, either way that is the query. ## I drove the vehicle after putting petrol in my diesel. Now what? Somewhere sensible, then stop, then turn off and keep it off. Driving is what moves the trouble from your tank into your pump and injectors — but it's fixable a lot more regularly than motorists expect, and the single most helpful thing you can do now isn't restart the car. ## Will a fuel drain void my warranty? No. Carried out properly, draining and purging is no modification at all, and the warranty from your manufacturer is unaffected by it. What is likelier to start an argument is a diesel that has been run on petrol. One more reason for the motor to stay off. ## Can I just add two-stroke oil and drive home? What petrol has weakened is not replaced by two-stroke oil, which is an old workaround for a distinct problem. So no. Your pump still has to put up with it, as your tank still has petrol in it later. ## A main dealer for petrol in a diesel — essential? There is no need to bring it to a main dealer, since our technicians drain and clean the vehicle wherever it is. ## Waiting next to it? The motor remains off. Driven it already? Then somewhere safe, stop, switch off, and no restarting it later. Cold and still, a motor is in the best position available — and drivers fear this much more than the recovery rate warrants. Throughout West Sussex and in West Wittering: call-out fuel draining, at home or on the forecourt or at the roadside.
