Don't Start It Don't turn on the engine. While the petrol is still inside the tank and your engine has not turned over, a tank drain is almost always all it requires — and that's determined in the following few minutes, not by how much got in. Petrol in Diesel drains and cleans wrong-fuelled vehicles where they stand, across Lower Eythorne and the rest of Kent, on the forecourt, by the roadside or on a private drive. We shall tell you what your next stage is. Call us — it goes before anything else. ## Petrol in a diesel: what to try next - Do not start it — and do not depend on it if it runs. Here is the thing motorists get wrong about petrol in a diesel especially. A petrol motor filled with diesel typically just won't run, and so the motorist stops and the wear ends with them. A diesel fed petrol generally starts, idles and moves off just fine for several miles. It is not all right. It's wearing out that fuel system as you drive. - Two tasks, diesel: it combusts, and on the way through it keeps your high-pressure fuel pump and injectors protected. Petrol only does the one. That is why the ignition is left off too — flick it on and you usually prime your system, and that is petrol leaving the tank for exactly those components. - Never weaken it. Diesel added on top removes nothing, and so all you have is more of what was already there, since percentage is not how a diesel fuel system handles petrol. Super unleaded? Still petrol. The octane makes no difference. - Sit tight if it's safe to. Hazards on, engine off, keep the vehicle. Wherever you have stopped — the verge on Shooters Hill, anywhere — a difficult location for us beats a started motor, and nothing is easier for us to sort out than a motor that never moved. - Before you phone, get your location. Anything closest to you with a sign on it, plus a postcode that starts CT15 4 — that is what determines whether our van shows up or circles. - Dial 0333 366 0103. Tell us what got in, approximately how many litres, and if the car has started. Those three answers settle the whole call-out. Nothing about the hours since has cost you anything. Fuel in a tank is inert, and so a diesel Volkswagen Golf parked at Shepherds Well this morning is no worse at five than it was at nine — what pushed weakened diesel through your pump was the run in. Ring us before you set off to fetch it. ## On a forecourt: removing petrol from your diesel A good share of this work gets done at the pump, since that is where it mostly begins. We work on station forecourts regularly, with the station's permission, so if you're still at Esso that is normally where this drain takes place. At the forecourt, the mistake gets spotted with your motor never started, and nowhere else does that. Anywhere else — a car park, a private drive, a lay-by — the vehicle was fired up and moved to get there, which means fuel was sucked from the tank, through the fuel filter then into the high-pressure pump. That's not a catastrophe, and we can still deal with it where it sits. It does mean the fuel lines and your filter need cleaning as well as your tank, and that's determined by the few seconds between seeing the receipt and going for your key. Clear of the petrol pump, the next customer can get past — so yes, let the staff help you wheel the vehicle. Well worth doing. Starting the car over four vehicle lengths? No. The complicated part is the bay, not the fuel. Motors either side of you, a trolley shelter behind, and occasionally a height limit on the way in that decides if a technician can reach you at all — so when you phone from a car park like the one at Co-op Food, mention how much clearance there's about you and which way round the vehicle is. Those our technicians cover frequently. Should there be no space to work next to the diesel Renault Megane, it gets moved with the engine off, and not out of pedantry over a few seconds of running: priming happens at every start, more of the mixture exits that tank for the pump, and two shunts into a better bay have quietly made a worse job of what was merely a car sitting still. ## Coverage around Lower Eythorne Being a residential suburb, Lower Eythorne gets a steady call, while the areas round about go with it on that same run: Upper Eythorne and Eythorne, Elvington and Barfrestone, Frogham. If yours isn't on this list it doesn't mean we never come — there are separate pages for the majority of towns across Kent, and the ones listed above are just the immediate neighbours. Ring us to check instead of assuming — borders especially, and wherever your phone can misread. The map is the area the page covers. All of it is ground we serve: a kerbside, a forecourt, a drive, a car park. You don't drive your car anywhere. Hazards on. Motor off. Phone us. It's twenty to nine at the gates of Eythorne Elvington Community Primary School, you're late, and your receipt reads unleaded — and even though three miles in your Skoda Octavia seems like nothing, fuel is metered to demand, and a hurried dash asks for plenty of that. ## Lower Eythorne: stuck where you pulled up The opportunity to pull over somewhere suitable doesn't fall to everybody. Hazards flashing at a lay-by somewhere, or stopped on the verge beside Wigmore Lane because you worked it out after setting off — our technicians take that call regularly enough that it is the normal kind. Sit with the car while it is sensible to sit there, yet clear of it if it isn't. Never fire it up to get to a safer place. It will go — a diesel on petrol usually obliges — and each mile of obliging draws that mixture deeper into the system. However awkward the location, it is no trouble for us to come to it, and that is a lot better for the vehicle than pressing on. ## So you've run it? Petrol in a diesel after a couple of miles Here is where your M20 comes in, under 10 miles away from Lower Eythorne. A misfilled diesel will often get you onto it and some distance along before anything feels wrong, and the symptoms when they come are usually a loss of power, a rough idle and smoke instead of a clean stop. Pull off at the first safe junction, turn off, and never restart it to reposition. On a longer run — anything close to the under 10 miles to the nearest city — assume the contamination has been through the fuel filter, your pump and the fuel injectors, and mention it when you phone. It affects what our engineers bring. A diesel injection system works hydraulically as well as chemically: the fuel has to hold pressure, not merely burn. Thin that fuel and pressure which should build and stay built leaks past gaps instead, leaving the motor a poorer, later, less even delivery than it was built round. Petrol thins diesel, and diesel has to be thick enough to seal the tightly fitted components it runs through — that's the entire process. It accounts for the ordinary Eythorne Playing Field call too: a diesel Mercedes C-Class that went out without complaint and came back down on power, lumpy at idle, perhaps smoking a little. None of which is the motor failing, and that's the bit worth hearing. The fuel has stopped behaving like diesel. Put the fuel right and it stops. ## Where is Lower Eythorne? Lower Eythorne is a suburban area in Kent, situated inland at an elevation of 63 metres, and is located near the city of Canterbury. Lower Eythorne has a population of around 1202 people and is characterized by predominantly detached housing. Lower Eythorne is part of a larger area that includes nearby Upper Eythorne and Eythorne, and is within commuting distance to London, being approximately 63.7 miles away. ## What comes next when our technicians reach you around Lower Eythorne - Our engineers ask first, price after. What went in? How much? Has your motor run? Those responses change what the work actually is. - The tank is emptied completely. - Fuel lines are rinsed through and your filter cleaned, leaving nothing in your system that started any of this. - Your system gets bled, on fresh diesel. - Our technicians fire it up and make sure it runs properly on new diesel. That has the car ready to drive away. Long-term damage is very uncommon when it has been noticed quickly, and since everything is done where the vehicle is, it never needs to go to a garage. ## AdBlue in your diesel tank by mistake, in Lower Eythorne? If what got in was AdBlue instead of petrol, the opening rule is unchanged — don't fire it up — but this issue isn't. Petrol does two things to diesel: thins it, and strips out the lubrication the system relies on. Urea in water, AdBlue, and in a diesel tank that brings rust and residue. AdBlue removal in Lower Eythorne has a page of its own with the detail on it, including why it is usually the more significant of the two. Our engineers deal with both. A throttle gone limp, white smoke, a lumpy idle, rattling: that is a misfilled diesel BMW 1 Series telling you what is wrong. Don't start it to find a better spot — switch off where you have stopped, by Eythorne or anywhere else. ## Lower Eythorne costs for a petrol-in-diesel fuel drain Our engineers cannot put one figure on this page frankly, since the job is not one job. What shifts it: - Started? Driven? Either answer counts more than anything else on this list. - How much of the wrong fuel got in, against how much your tank can hold. - Which went in: unleaded or AdBlue. - Access: the vehicle's position, and if working on it there is sensible for a technician. A firm answer instead of a range is what you get for telling us three things: the vehicle, the amount, and if it has run. If it is not urgent — the car is at home and going nowhere — is fine too. ## Petrol in diesel: frequent questions in Lower Eythorne ## At a petrol station in Lower Eythorne, can you do a fuel drain there? A big portion of this work happens there, so yes. Our engineers attend Tesco and the other forecourts around town all the time, with the station's agreement — tell us which one you are at when you call and we will tell you if our technicians can work there. ## Is there a sensible amount of petrol in a diesel? Litres aren't the yardstick. Ratio is, and much more than either, it counts whether anything has been run. What determines how much work is required is whether that mix has been pulled through your fuel system — because although five litres in an almost empty tank is a distinct matter from five in a full one, either way that's the question. ## I drove the car after putting petrol in my diesel. Now what? Somewhere safe, then stop, then turn off and keep it off. Driving takes the problem along — out of that tank, into the pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one truly valuable thing left to you isn't restarting it. ## Will a fuel drain void my warranty? A manufacturer's warranty survives a drain and flush done to a proper standard, which is no alteration at all. Another reason to leave it turned 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? Two-stroke oil solves a different issue, and an old one at that. Nothing it does puts back what petrol diluted. No. After that? Still petrol in your tank, and a pump that has to live with the stuff. ## Do I need a main dealer for petrol in a diesel? Wherever your car is, we drain and flush it there, so a drive to the main dealer does not come into it. ## Is your vehicle still with you? Keep the engine shut off. Driven it already? Then somewhere safe, stop, switch off, and no restarting it after that. Cold, parked, going nowhere: that is the best position to be in. People fear this a lot more than they need to. At the roadside, on the forecourt or at home — call-out fuel draining around Lower Eythorne and across Kent.
