Don't Start It If you have not turned on the motor yet, don't. A drain and nothing more is nearly always what a car requires while the petrol is still in that tank and the engine has not turned over, which is why it's the coming few minutes that matter, not how much was put in. Petrol in Diesel goes to the car wherever it has ended up in Creekmouth or the rest of Greater London, on the forecourt, at the roadside or on a private drive, and drains and cleans it there. One ring our way is sufficient: our technicians will show you what comes after this. Try it right away. ## Your first five minutes: petrol in a diesel - Do not start the car — and do not believe it when it does start. Here is the thing motorists get wrong about petrol in a diesel especially. A petrol motor fed diesel usually just can't run, and so the person stops and the wear ends with them. A diesel given petrol usually starts, ticks over and drives off quite happily for several miles. It is not fine. It is eating into that fuel system as you drive. - Leave the ignition be also. Diesel performs two roles: it combusts, and before it combusts it lubricates that high-pressure pump and its injectors. Petrol handles the first and not the second. Switching the ignition on is frequently enough to prime the system, which carries that petrol out of the tank and into precisely those parts. - Do not put diesel on top to thin it. A diesel fuel system won't handle petrol by percentage as that guidance assumes, and topping up removes nothing — it merely gives you a larger tank of the same mix. The grade makes no difference either: super unleaded is still petrol. - A vehicle that hasn't moved is the quickest one to sort out, so wait where you are if you sensibly can. Stopped on the verge on River Road? Hazards on, and leave it there. A difficult location suits us better than a started diesel. - Our van arriving instead of circling turns on two things: a postcode that starts IG11 0, and whatever is nearest to you with a sign on it. Get both prepared before you call. - Three facts decide your whole job: the fuel you put in, the approximate amount of it, and whether it has been turning since. The number is 0333 366 0103. Quarter past eight. A hurried fill-up on the trip in. At about eleven it dawns on you, and by then your diesel Volkswagen Passat has stood at Barking Riverside for three hours. Phone us and keep the car where it is. What is key is the run in, since diesel both combusts and — before that — greases your pump and the fuel injectors, but petrol only ever ignites. Those couple of miles worked your pump on a liquid drained of a lot of its protection, and no quantity of standing in a car park adds any of that back. Hence the thing we ask about miles rather than hours standing, and hence the instruction to leave the keys be until our engineers arrive. ## Can petrol be taken from your diesel on a forecourt? The work kicks off at a forecourt, usually. Quite often the job wraps up on site too. If you are still on the forecourt at BP, that is generally where this drain gets done — we operate on station forecourts regularly, with the station's agreement. Before your motor has run — a garage is the one setting the mistake is caught. Fuel drawn out of the tank and through your filter, all the way to the high-pressure fuel pump, is what occurs when your engine is switched on and the vehicle is driven to where it is now: the car park, the driveway or the lay-by, everywhere other than the forecourt. So the flush takes in the fuel filter and the lines together with your tank. That is still not a calamity, and our technicians sort it out where the vehicle is. What determines it is whether the ignition was turned in the seconds after the receipt was checked. Clear of the pump, the next motorist can get by — so yes, let the attendants help you move the car. Worth doing. Four vehicle lengths is not worth a restart. The difficult part is that bay, not your fuel. Motors either side of you, a trolley shelter behind, and occasionally a height limit on the way in that decides if a van can get to you at all — so when you phone from a car park like the one at Co-op Food, say how much room there's round you and which way round your car is. Those our technicians attend regularly. Should there be no space to work next to your diesel Renault Clio, it gets moved with the motor off, and not out of fussiness over a couple of seconds of running: priming occurs at every start, more of the mixture departs that tank for the pump, and two shunts into a nicer space have silently made a harder job of what was simply a vehicle standing still. ## Service near Creekmouth Barking Riverside, Cavendish Square, Thamesmead, Castle Green, Barking — all of those on the runs that take us out to Creekmouth as well, a residential suburb. There are pages for most places around Greater London, and the ones listed above are just the immediate neighbours — so yours being absent from the list says nothing at all about whether we come. Ring us and check rather than guessing — boundaries especially, and anywhere the satnav might struggle with. This map shows the ground the page includes. We operate at the roadside, on forecourts, on driveways and in car parks over all of it, and your car does not need to travel to us. ## Creekmouth: stuck wherever you parked Not everyone has a suitable spot to pull in. If you realised after setting off and ended up by the verge of Long Reach Road, or at a lay-by somewhere with the hazards flashing, that is a normal call for us and not an unusual one. Stay with the motor when it's wise to wait there, yet clear of the car if it's not. Every mile a diesel obliges you for on petrol draws that mix further into your fuel system — and oblige it usually will, which is why the motor doesn't get restarted to limp somewhere better. Our van driving to an awkward location is no problem for us, and it's far better for your car than carrying on. Never risk it. The journey home from The Lighterman is perfectly possible, which is precisely the trouble — a diluted tank doesn't stop a diesel starting or pulling away, it just grinds the components the fuel is meant to protect. Phone, and let the Audi A4 stay where it stands. ## So you've run it? Petrol in a diesel over a few miles Here is where the local M11 comes in, under 10 miles out of Creekmouth. It will frequently take you onto it, and some way along, before you feel a thing. Then it is some smoke, a rough idle and power ebbing away — not a tidy stop. Misfilled diesels rarely give you one of those. Get off at the next sensible exit, switch off, and don't restart it to move it. It affects what our technicians bring, so tell us when you phone: on a longer drive — anything close to the under 10 miles to the nearest city — take it the mixture has been through your filter, your pump and the injectors. Fine on the way out, flat on the way back. If that is how the trip to Creekmouth Open Space went, that tank is where to look. Petrol thins diesel, and thinner fuel seeps past the close-fitting parts that are supposed to build injection pressure — so the further your Mercedes C-Class went, the less well it held that pressure. Pull in somewhere safe, switch off and call us. ## All about Creekmouth Creekmouth is a small suburban area in the London Borough of Barking and Dagenham, situated on the north bank of the River Thames. Creekmouth sits at a low elevation of around 3 metres, close to the mouth of the River Roding.

Creekmouth is located approximately 9.7 miles from central London, with the city of London being around 8.2 miles away. ## The visit around Creekmouth, step by step - Our engineers find out what got in, how much, and whether your engine has run. The responses change the work, which is why we ask before giving a price. - That tank is drained of everything. - Fuel lines are rinsed through and the fuel filter cleared, leaving nothing in your system that created any of this. - Priming follows, once new diesel is in. - Our technicians fire it up and make sure it runs smoothly on clean diesel. From there, you are ready to drive away. Lasting damage is very unusual when it has been spotted quickly, and because all of it is done where the car is, it never needs to go to a garage. Why so firm about leaving the keys alone? Because your pump is ahead of the fuel injectors, and a worn-out one sends whatever it loses on with your fuel. Call us. Leave the Vauxhall Astra by Soul Searching in Creekmouth. ## AdBlue in the diesel tank by mistake, around Creekmouth? If what went in was AdBlue rather than petrol, the opening step is unchanged — never crank it — yet the problem is not. Petrol thins the diesel and takes away the lubrication your fuel system relies on. AdBlue is urea dissolved in water, and in a diesel tank it causes corrosion and deposits instead. Frequently the more significant of the two, AdBlue — and the details lives on its own Creekmouth page. Both are ours to handle. ## Paying for a petrol-in-diesel fuel drain around Creekmouth What changes the figure is laid out below, because this job is not one job and we cannot honestly put a single number on this page. - Whether the motor has been run or driven. This is the big one. - Wrong fuel in, against what that tank takes — that ratio. - Which went in: petrol or AdBlue. - Where is it? And can our van get to it and work there safely? The vehicle, the quantity, whether it has run — give us those and the answer comes back straight instead of as a range. Vehicle at home, going nowhere, nothing time-critical about it — is good for that. ## Creekmouth drivers ask us these about petrol in diesel ## Can you do a fuel drain at a petrol station around Creekmouth? Yes, and it's where a good part of this work gets done. Consent from the site is the condition. Given that, a forecourt like Tesco Petrol is somewhere we're regularly, along with the rest of them locally — so name yours on the call and you'll hear if working there is possible. ## A couple of litres of petrol in a diesel — too much? Litres aren't the measure. Proportion is, and much more than either, it counts if anything has been run. Five litres in a nearly empty tank is a separate situation from five in a full one — but either way, the thing that decides how much work is required is if that mix has been drawn through the system. ## Petrol in my diesel, and I have driven the vehicle Stop sensibly. Off. Nothing after that. Not restarting it is the single most valuable thing available to you now. Driving does move the problem out of that tank and into the pump and injectors, yes, and it stays recoverable much more commonly than drivers fear. ## My warranty — does a fuel drain void it? A manufacturer's warranty survives a drain and flush done to a good standard, which is no modification at all. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it turned off. ## Adding two-stroke oil, then driving home No. Two-stroke oil is an old remedy for a separate fault and it doesn't put back what petrol has diluted. Later on? Still petrol in that tank, and a pump that has to put up with the stuff. ## A main dealer for petrol in a diesel — needed? There is no need to take it to a franchised dealer, as our engineers drain and flush the vehicle wherever it is. ## Is the car still with you? Switched off is how it remains. If you have already driven the car, stop somewhere safe, turn it off then leave it off. This is recoverable from much more commonly than drivers expect, and a stationary, cold vehicle is the best place to be in. Across Greater London and around Creekmouth: call-out fuel draining, at home or on the forecourt or at the roadside.
