Don't Start It Petrol in Diesel drains and cleans wrongly fuelled vehicles where they sit, on the forecourt, by the roadside or on a private drive, across Friday Street and the rest of East Sussex. The first thing to do is not to start the motor. When the motor has not yet been started and the petrol is still inside that tank, a fuel drain is almost always all it needs, and the next few minutes decide that, not how much was put in. We will tell you what the next move is. Phone — that comes ahead of anything else. ## Your next five steps: petrol in a diesel - Feed a petrol engine diesel and it will typically refuse to run at all, and so the driver stops there and so does the damage. Feed a diesel petrol and the engine starts, it ticks over, it pulls away — all right for several miles. Motorists have that reversed, which is the thing they get wrong about petrol in a diesel especially. So never fire it up. And if started, do not believe it: that fuel system is wearing as you drive. - Two jobs, diesel: it ignites, and on the way through it keeps the high-pressure fuel pump and injectors protected. Petrol only does the one. Which is why your ignition is left off also — turn it on and you frequently prime that system, and that's petrol leaving the tank for exactly those components. - That advice assumes a diesel fuel system copes with petrol by percentage. It will not. Put diesel on top and nothing at all is taken out; what you get is a bigger tank of the same blend. And no, the octane makes no difference — super unleaded is just petrol. - We would much rather get to a difficult location than have it started — so if you safely can, stay still. Nothing is quicker to sort out than a car that hasn't shifted. On the verge on Oak Tree Lane, that means hazards on then keep the car. - Before you ring, get your whereabouts. Anything closest to you with a label on it, plus a postcode that starts BN23 8 — that is what decides whether the technician turns up or circles. - Three answers settle your whole visit: the stuff you tipped in, the ballpark volume of it, plus whether anything has been running since. Our line is 0333 366 0103. ## Pump-side drains for petrol in a diesel A big chunk of this work ends up finished at a pump, since that's where it usually kicks off. Still at Esso? Then that is usually where it happens. Petrol station forecourts are normal for us, with the consent of the site. A forecourt is the only spot it can be halted before your motor has started. Everywhere else — a car park, a driveway, a lay-by — your car was started and driven to get there, which means fuel was sucked from the tank, through the filter and into your high-pressure pump. That's not a disaster, and our engineers can still put it right where it is. It does mean your lines and the fuel filter need cleaning as well as the tank, and that is determined by the few seconds between seeing the till receipt and reaching for the keys. Staff will normally chip in pushing it out from the petrol pump, which lets the next motorist get by. Accept the assistance. Shifting the car four bays does not justify starting the engine. ## Coverage near Friday Street Stone Cross, Langney, Blackness, Dittons, Jenkins Green — all of them on our journeys that bring us across to Friday Street too, a residential suburb. If yours isn't on that list it does not mean we never come — there are dedicated pages for most locations around East Sussex, and the ones listed above are simply the immediate neighbours. On a border, or somewhere your satnav can't find? Ring us to ask instead of assuming. The area this page covers appears on the map. Every bit of it is territory our engineers cover: a kerbside, a forecourt, a private drive, a car park. You do not bring the vehicle anywhere. You will be advised to shift the vehicle clear of the gateway and fix it later. Please don't. On the zig-zags outside Shinewater Primary School, a wrongly fuelled Skoda Octavia running on diesel is in the way, and that is all it is. Crank it three more times being helpful and you have turned a tank into a fuel system: every start primes the fuel lines, every prime pulls more petrol beyond the filter towards your pump. Let them moan. Call us. ## Stuck on the roadside near Friday Street Some drivers have no safe spot to stop at all. Set off, then noticed? Landed along the verge beside Friday Street, or parked in some lay-by with your hazards on? That is a common call here. Not an unusual one. Safe right there? Stay by it. Not safe? Step out and away from it. It will often oblige. A diesel running on petrol limps along perfectly willingly, and that is the catch: start it up to reach somewhere safer and that mix goes further into your fuel system with every mile travelled. However awkward the spot, it is no problem for us to get to it, and that's far better for the car than carrying on. Here's what a job in the car park at Farm @ Friday Street typically looks like. Our engineers arrive at the car, ask what went in, approximately how much, and whether the motor has run since — these three answers decide much of the work. Then the contaminated mix comes out of the tank, your lines get rinsed, and the fuel filter comes off where your BMW 3 Series has a replaceable one. Fresh diesel goes in and the system is bled. Then our technicians start the car, confirm it runs correctly, and you set off. ## A few miles on petrol in a diesel: now what? under 50 miles out of Friday Street, the M23 is what counts here. Some distance along, and onto it in the first place: a misfuelled diesel will usually do both before anything seems wrong. What you get then is rarely a tidy stop. Power ebbs away, your idle turns lumpy, and there may be smoke. Don't start it to move it. Pull off at the first sensible junction then turn off. It alters what we bring, and so tell us when you ring: on a longer run — anything near the under 25 miles to the closest city — assume the petrol has been through your filter, the pump and your injectors. A diesel injection system works hydraulically as well as chemically: your fuel has to hold pressure, not only burn. Dilute that fuel and pressure which should build then stay built leaks past gaps instead, leaving the motor a poorer, later, less even delivery than it was built around. Petrol dilutes diesel, and diesel has to be viscous enough to seal the precision parts it flows through — that's the full process. It accounts for the ordinary Adur Park call too: a diesel Audi A4 that went out without fuss and came back down on power, uneven at idle, possibly smoking a little. None of which is the motor failing, and that is the bit worth hearing. The fuel has stopped behaving like diesel. Put your fuel right and it stops. ## Friday Street itself Friday Street is a suburban area in East Sussex, situated near the coast and approximately 19 miles from Brighton and Hove. Friday Street lies close to nearby places such as Stone Cross, Langney, and Blackness, and is characterised by its semi-detached housing stock. Friday Street has a population of around 7147 people and is located at an elevation of 22 metres above sea level. Friday Street is also within commuting distance of London, being around 51 miles from the capital. ## What we do when our engineers arrive with you around Friday Street - Our technicians establish what went in, how much, and whether the engine has run. The responses alter the work, which is why our engineers ask before quoting. - We empty the tank of all the polluted mixture. - What is left in the system should not be what caused the problem, so the fuel lines get rinsed and your filter cleaned. - Your system gets primed, on fresh diesel. - The motor is started and checked to confirm it runs correctly on new diesel. The car is then ready for you to pull away. We do everything wherever your car has ended up, which means it never has to go to a workshop, and if it has been noticed early, it's very unusual for there to be lasting damage. Our technicians flush your lines rather than only clearing your tank, and the reason is that diluted fuel has already got to the filter and the pump: it was a start and a drive, however short. The distance truly helps — pulled off the forecourt, receipt read, a diesel Ford Focus parked up by Shinewater Sports Centre a few hundred yards later is about as well as this goes once the engine has turned. Call us then leave it off. ## AdBlue in a diesel tank around Friday Street is a different problem AdBlue rather than petrol? Then the opening step is unchanged — your motor remains off — while the issue underneath it is a separate one altogether. Petrol weakens the diesel and strips the lubrication the fuel system depends on. AdBlue? Urea dissolved in water. Put that in with the diesel and you get corrosion instead, plus residue. AdBlue removal in Friday Street has a page of its own with the full story on it, including why it's often the more significant of the two. We handle both. Petrol in a diesel does its damage as a share, which is the reason our technicians ask at all: the same few litres resting in a nearly empty tank make a far stronger mixture than they would in a full one. And petrol is rated on how well it resists 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. Almost nobody knows how full your tank was in a motor picked up two days ago, and our engineers work that out there. Do ring the hire or company firm first, though: some agreements want them to sign off the work, and that is far quicker settled before than after. Then phone us about the Mercedes C-Class close to Langney Shopping Centre. ## How much is a petrol-in-diesel drain in Friday Street? One figure wouldn't be fair here, since this isn't one job. These are the things that change it: - This is the main one: whether the motor has been run, or driven. - How much of the wrong fuel got in, weighed against how much the tank takes. - AdBlue or unleaded, whichever was put in. - Access: the car's position, and whether working on it there's sensible for a van. A straight answer instead of a range is what you get for telling us three things: the vehicle, the quantity, and whether it has run. For your car at home that's going nowhere and is not pressing, is fine too. ## Petrol in diesel: common questions around Friday Street ## I am on a forecourt in Friday Street. Can you drain the vehicle here? Plenty of what our engineers do gets done nowhere else. So yes. Tell us which one you're at when you ring and we'll tell you whether our technicians can work there. With the station's permission we attend Morrisons and the other forecourts around town all the time. ## Is there a safe quantity of petrol in a diesel? Ratio settles it rather than litres — and more than either, whether the engine has run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same query in the end: has that mixture been pulled right through, or has it not? ## Petrol in my diesel, and I have driven the car Somewhere sensible, then stop, then switch off and leave it off. Driving takes the issue along — out of the tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you isn't restarting the vehicle. ## Fuel drains and manufacturer warranties A manufacturer's warranty outlasts a drain then flush done to a good standard, which is no modification at all. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it turned off. ## Two-stroke oil in your tank, and then home? No. Two-stroke oil is an old fix for a separate fault and it doesn't restore what petrol has weakened. The pump still has to cope with it, because the tank still has petrol in it after that. ## Main dealers and petrol in a diesel You do not need one. The vehicle is drained and flushed wherever it is, with no need to take it to a main dealer. ## Is the vehicle still with you? That engine remains off. Driven it already? Then somewhere safe, stop, switch off, and no restarting it after that. Cold, stationary, going nowhere: that is the best position to be in. Drivers fear this much more than they need to. Throughout East Sussex and in Friday Street: mobile fuel draining, at home or on the forecourt or at the kerbside.
