Never fire up the engine. If the fuel is still inside that tank and the motor has not been started, a tank drain is nearly always all it needs — and that's decided in the following few minutes, not by how much was put in. Petrol in Diesel drains and cleans wrongly fuelled vehicles where they stand, all over Rudgwick and the remainder of West Sussex, on the forecourt, by the roadside or on a driveway. Call us so our engineers shall show you what happens next before you attempt anything else. ## Now what? Petrol in a diesel, in order - Feed a petrol engine diesel and it will usually refuse to run at all, and so the motorist stops there and so does the damage. Feed a diesel petrol and the car starts, it ticks over, it pulls away — all right for a few miles. Motorists have that reversed, which is the thing they get wrong about petrol in a diesel in particular. So don't crank it. And if started, don't believe it: the fuel system is grinding while you drive. - Two things, diesel: it burns, and on the way through it keeps the high-pressure pump and injectors protected. Petrol only does the one. That is why the ignition is left off as well — turn it on and you frequently prime that system, and that is petrol leaving the tank for just those components. - Do not thin it. Diesel poured on top clears nothing, and so all you have is more of what was already there, since percentage is not how a diesel fuel system tolerates petrol. Super unleaded? Just petrol. The octane makes no difference. - Sit tight if it's sensible to. Hazards on, ignition off, keep the vehicle. Wherever you have stopped — the verge on Furze Road, anywhere — an awkward spot for us is better than a started engine, and nothing is simpler for us to sort out than a motor that never moved. - A van showing up instead of circling rests on two things: a postcode starting RH12 3, and whatever is nearest to you with a sign on it. Get both prepared before you dial. - Ring 0333 366 0103. Let us know what was put in, about how many litres, and also whether the motor has fired. Those three facts shape the full visit. The journey back would close to double it, for no purpose at all. One commute has already forced a real load of petrol-thinned diesel through the high-pressure fuel pump of your Volkswagen Passat. So leave it where it is. Phone us from the platform if that's quicker — nobody needs you standing over the car at Christs Hospital whilst we work, and tonight is better than finding out on Monday. ## Can petrol be pumped out of your diesel at a forecourt? It kicks off at a forecourt, typically. Frequently the work wraps up on site too. Still at BP? Then that is usually where it happens. Garage forecourts are routine for us, with the consent of the site. Before your engine has started — the forecourt is the single setting it ends up spotted. Anywhere else — a car park, a driveway, a lay-by — your car was switched on and moved to get there, which means fuel was sucked from your tank, through the filter and into your high-pressure pump. That is not a disaster, and our engineers can still deal with it where it stands. It does mean the lines and the fuel filter need rinsing as well as your tank, and that is settled by the few seconds between seeing the till receipt and going for your key. Staff will normally help out pushing it away from the pump, which lets the next motorist get by. Take the offer. Four vehicle lengths isn't worth a start. ## Coverage near Rudgwick As a rural village, Rudgwick gets a steady visit, and its neighbours close by come with it on that same journey: Bucks Green and Tismans Common, Ellens Green and The Haven, Rowhook. Not on this list? That tells you nothing. The names above are simply the closest few, and nearly all locations in West Sussex have a page of their own elsewhere on the site. Phone to ask instead of assuming — boundaries particularly, and wherever the satnav tends to get wrong. Look at the map for the area included here. The lot is territory our engineers work: a kerbside, a forecourt, a driveway, a car park. You do not drive the vehicle anywhere. ## Stuck by the kerbside somewhere in Rudgwick? The opportunity to pull in somewhere suitable does not come to everyone. Set off, then realised? Ended up on the verge on Church Street, or parked in some lay-by with the hazards going? That is a routine call here. Not an odd one. Whether you remain by your car or move clear of it turns on whether being in it seems sensible. Every mile a diesel obliges you for on petrol drags the blend further into your fuel system — and oblige it frequently will, which is why your motor does not get restarted to limp somewhere better. Driving on does the vehicle far more harm than our van coming out to an inconvenient location, and that's no trouble for us. You head off at the end, once our technicians have fired it up and made sure it runs correctly on clean diesel, with your system bled. Before that, in the car park at The Fox Inn, the tainted fuel comes out of the tank, the fuel lines get cleaned and the filter comes off where your Ford Focus has a serviceable one. Everything begins with three questions when our engineers get to your car: what was put in, how much of it, and whether it has been fired up since. ## Petrol in a diesel, and the motor has moved This is where the local M23 comes in, under 15 miles away from Rudgwick. Some distance along, and onto it in the first place: a misfilled diesel will usually do both before anything feels wrong. What you get then is rarely a clean stop. Power falls away, the idle gets lumpy, and there may be smoke. The first sensible exit is the one to take. Switch off there, then leave the restarting alone. Assume the worst of that on a long run. Anything approaching the under 25 miles to the nearest city, and the mixture has been through your filter, through the pump, through your injectors. Tell us when you phone. What our technicians bring alters. A diesel injection system works hydraulically as well as chemically: your fuel has to hold pressure, not only burn. Thin that fuel and pressure which should build then stay built bleeds past clearances instead, leaving the engine a poorer, later, less even delivery than it was designed around. Petrol thins diesel, and diesel has to be heavy enough to seal the precision parts it passes through — that's the whole process. It explains the ordinary Gravatt's Hanger call too: a diesel Mercedes C-Class that drove out without fuss and came back down on power, uneven at idle, possibly smoking a little. None of which is your engine failing, and that's the bit worth hearing. Your fuel has stopped behaving like diesel. Put your fuel right and it stops. ## Where's Rudgwick? Rudgwick is a village in West Sussex, situated inland at an elevation of 54 metres, with a mix of rural and residential areas. Rudgwick lies near the villages of Bucks Green, Tismans Common, and Ellens Green, and is approximately 22.7 miles from Chichester. Rudgwick has a population of around 1185 people, predominantly living in detached houses. Rudgwick is also within commuting distance of London, being around 31.9 miles from the city. ## What we do when our engineers arrive with you around Rudgwick - Our technicians establish what got in, how much, and if the engine has run. The replies change the work, which is why we ask before pricing. - Your tank is emptied of it. - What is remaining in the fuel system shouldn't be what started the issue, and so the lines get rinsed and the filter cleaned. - Fresh diesel goes in, and then the fuel system gets bled. - After it is turned on, our engineers check it runs correctly on fresh diesel. From there, you're ready to drive away. Our technicians do all of it wherever the vehicle has ended up, which means it never needs to go to a workshop, and if it has been noticed quickly, it is very uncommon for there to be lasting damage. Emptying the Audi A3, changing the fuel filter where there's a usable one, cleaning the lines, putting clean fuel through the full system: that's this job, and it is shaped by the worst of that waiting in your lines rather than in your tank by this point. Three things help when you ring from near Holy Trinity Church — which side the filler is on, whether a van can pull up next to without blocking the road, and whether the motor has run since you filled up. On-street is the commonest spot our technicians work, and so the location itself is hardly ever the issue. A cramped parking bay beats a car driven somewhere more convenient. ## Rudgwick AdBlue removal is a different job If what got in was AdBlue instead of petrol, the opening step is unchanged — do not fire it up — but the fault isn't. Thinned diesel, and no protection left for the system that depends on it. That is petrol. Rust and residue are what a diesel tank gets instead, because AdBlue is urea in water. Our technicians deal with both, and AdBlue removal in Rudgwick has its own page with the detail — including why it's often the more significant of the two. ## Rudgwick pricing for a petrol-in-diesel fuel drain Honestly, no single number fits on a page like this. The job varies. Here's what changes it: - Whether your engine has been run or driven. This is the key one. - How much of the wrong fuel got in, measured against how much that tank can hold. - Which got in: petrol or AdBlue. - Access: the vehicle's position, and if working on it there's safe for a technician. Tell us the vehicle, the amount and if it has run, and you'll get a clear answer instead of a range. If it's not time-critical — the car is at home and going nowhere — works too. The filter, your lines, your pump and the rail: that is where that mix is once a diesel has run, and it does not come back out with the tank contents. So that tank is not where most of the damage rests by this point, and a diesel Citroen C3 that got near Motte needs your system flushed rather than drained. ## Rudgwick motorists ask us these about petrol in diesel ## At a petrol station around Rudgwick, can you do a fuel drain there? A good share of this work takes place there, so yes. Regularly, provided the site agrees: Shell, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether we can work in that place is something our engineers answer straight away. ## How much petrol in a diesel is too much? Whether your engine has run matters far more, though the proportion matters too, rather than the litres. Five litres into a nearly dry tank is not five into a full one, no. But both land on the same question in the end: has that blend been pulled right through, or has it not? ## Petrol in my diesel, and I have driven it Somewhere safe, then stop, then switch off and keep it off. Not restarting it is the single most helpful thing available to you now. Driving does shift the problem out of your tank and into your pump and injectors, yes, and it stays fixable a lot more commonly than people expect. ## Will a fuel drain void my warranty? A drain then flush carried out correctly isn't a change and does not cancel a manufacturer's warranty. Another reason to leave it turned off: running a diesel on petrol is the thing more likely to cause a dispute with one. ## Adding two-stroke oil, then driving home Two-stroke oil solves a different problem, and an old one at that. Nothing it does puts back what petrol weakened. No. The tank still has petrol in it after that, and the pump still has to live with it. ## A main dealer for petrol in a diesel — necessary? Not at all. We drain and clean the vehicle wherever it is, so there's no need to take it to a main dealer. ## Still with the vehicle? Turned off is how it remains. Switch it off somewhere safe and keep it off, if you have already driven it. Cold and stationary, a motor is in the best place available — and drivers fear this much more than the recovery rate warrants. Throughout West Sussex and around Rudgwick: call-out fuel draining, at home or on the forecourt or at the roadside.
