Don't Start It Don't turn on your engine. If the petrol is still sitting in the tank and the engine has not turned over, a drain is almost always all it needs — and that's settled in the coming few minutes, not by how much was put in. Petrol in Diesel drains and flushes wrongly fuelled vehicles where they stand, throughout Low Seaton and the remainder of Cumbria, on the forecourt, by the roadside or on a driveway. Contact us before everything else happens, and you will hear what happens from there. ## What next? Petrol in a diesel, in order - Never fire it up — and never rely on it if it starts. That is the bit drivers get wrong about petrol in a diesel in particular. A petrol engine given diesel typically just can't run, so the motorist stops and the harm stops with them. A diesel filled with petrol generally starts, idles and drives off perfectly well for a couple of miles. It isn't okay. It is wearing the fuel system whenever you drive. - Leave your ignition off too. Diesel performs two roles: it ignites, and before it ignites it greases your high-pressure fuel pump and its injectors. Petrol manages the first but not the second. Switching the ignition on is commonly enough to prime the system, which draws the petrol out of the tank then into just those components. - Do not tip diesel on top to dilute it. A diesel fuel system will not tolerate petrol by percentage as that advice implies, and topping up removes nothing — it simply hands you a fuller tank of the same mix. The grade makes no difference either: super unleaded is simply petrol. - Remain where you are if you reasonably can. A car that has not shifted is the easiest one to handle, and we would sooner come to a tricky place than have it started. If you're parked on the verge on Causeway Road, turn those hazards on then keep the vehicle there. - Find out where you are before phoning. A postcode that starts CA14 1, and the name of whatever is nearest to you. Otherwise the van circles rather than arriving. - Three details determine the entire call-out: the fuel you put in, the ballpark measure involved, and whether anything has been turning since. Our line is 0333 366 0103. Quarter past eight, a hurried fill-up on the road in, and you realise around eleven — by which time the diesel Renault Megane has been left at Workington for three hours. Phone us and keep the vehicle precisely where it stands. The run in is the thing that counts most, because diesel does two jobs on its way through the engine: it burns, and before it ignites it greases that high-pressure fuel pump and the injectors. Petrol manages the first and not the second. So those couple of miles were travelled with the pump working on a liquid that had lost much of the protection it is designed around — which is why the thing our engineers ask is how many miles you travelled, not how long your car has been standing. ## Removing petrol from the diesel on the forecourt Most of the work begins at the pump, so a big share of that gets done at one. Still at Esso? Then that's generally where it happens. Station forecourts are normal for us, with the permission of the site. Nowhere else but the forecourt can it be caught with your motor still unrun. The few seconds between reading your receipt and reaching for the key decide how much requires flushing. Everywhere other than a forecourt — a car park, a drive, a lay-by — the vehicle was fired up and moved to get there, so fuel was pulled from your tank, through your filter then into the high-pressure pump. That means the fuel lines and your filter require cleaning as well as the tank. It's not a catastrophe, and our technicians can still sort it out where the vehicle stands. Roll the vehicle out of the way if the attendants volunteer, and they generally will. The next customer gets by the pump, and that's worth doing. Rolling the car four bays doesn't warrant starting the motor. How much fuel your pump has drawn is what we are actually asking — not how long ago any of that was. So the phone call our engineers like sounds like this: diesel Skoda Octavia, some litres of unleaded, a couple of miles covered, now turned off at Asda. ## Low Seaton and the villages next to it Those same trips carry us to Seaton, High Seaton, Barepot, Stainburn and Camerton besides Low Seaton, which is a residential suburb. If yours is not on that list it does not mean we don't come — there are separate pages for the majority of towns in Cumbria, and the ones mentioned above are merely the closest neighbours. Presuming is the mistake to avoid, especially on the boundary or somewhere the satnav goes wrong. Ring us to check. Use this map for the area shown here. Your vehicle does not need to come to us. We operate throughout the lot — kerbside, forecourts, driveways, car parks. ## Low Seaton: broken down wherever you parked Not everyone has a safe spot to pull in. If you realised after setting off and ended up along the verge beside Kelsick Park, or in a lay-by somewhere with the hazards flashing, that is a normal call for us instead of an unusual one. Clear of your car when it's not sensible to be in it, by it when it is. Don't restart it to reach a nicer place. It will go — a diesel on petrol usually obliges — and each mile of obliging draws that mixture deeper into the fuel system. We will take our van to a difficult location without any fuss, and for the vehicle that is far better than pressing on. ## Run it already? Pull over, and read this under 50 miles from Low Seaton, the Southwaite Services Northbound is what counts now. Some way along, and onto it in the first place: a wrongly fuelled diesel will frequently do both before anything feels wrong. What you get then is rarely a neat stop. Power falls away, your idle goes rough, and there may be some smoke. The first safe junction is the one to take. Switch off there, then leave the restarting alone. Long trip? Anything close to the under 50 miles to the closest city and you should assume the lot — filter, pump, injectors, all of it got to by the petrol. Say that on the phone, as it affects what goes in the van. Diesel has to be thick enough to seal the close-fitting components it flows through, and petrol weakens it. That's the full process, and it accounts for the normal Scarbank Wood call: a diesel Dacia Duster that went out there without fuss and came back down on power, uneven at idle, possibly smoking a little. A diesel injection system works hydraulically as well as chemically — it needs the fuel to hold pressure, not only to burn — so when the fuel weakens, pressure that should build then stay built starts bleeding past tolerances instead, and the engine gets a poorer, later, less even delivery than it was designed about. None of that is the engine failing, which is the bit worth hearing: it is your fuel no longer acting like diesel, and it stops when the fuel is corrected. ## A bit about Low Seaton Low Seaton is a coastal suburban area in Cumbria, situated near the towns of Seaton and Workington. Low Seaton lies at an elevation of 55 metres, with views out to the Solway Firth and the Scottish coast. Low Seaton has a mix of housing types, but semi-detached homes are particularly prevalent in the area. Low Seaton is located approximately 28 miles from Carlisle, the nearest city. ## Our call-out around Low Seaton, step by step - Our engineers check what went in, how much, and if the motor has run. The replies change the work, which is why our engineers ask before giving a price. - The tank gets emptied completely. - Lines purged, filter cleared. Whatever is left after that is not the thing that caused the problem. - Clean diesel goes in, and then your system gets primed. - The engine is started and checked to be sure it runs smoothly on new diesel. That leaves the car ready to pull away. All of this is done where the vehicle is, so it never needs to be taken to a garage, and when it has been noticed quickly, lasting damage is very rare. Why so direct about leaving the keys alone? Because your pump is ahead of the injectors, and a wearing one sends whatever it sheds on with the fuel. Ring us. Leave the Peugeot 3008 by Seaton bowls Club. ## Low Seaton AdBlue removal is a different job AdBlue instead of petrol? Then the first rule is unchanged — your motor stays off — while the fault underneath it is a different one altogether. Petrol does two things to diesel: thins it, and strips out the protection the system depends on. Rust and residue are what a diesel tank ends up with instead, as AdBlue is urea dissolved in water. Frequently the more serious of the two, AdBlue — and the full story sits on its own Low Seaton page. Both are ours to handle. ## Budgeting for a petrol-in-diesel drain around Low Seaton Our technicians can't put one figure on this page honestly, as this job is not one job. What moves it: - Started? Driven? Either answer matters more than anything else on this list. - Wrong fuel in, against what your tank holds — that ratio. - AdBlue or unleaded, whichever went in. - Where is it? And can our van get to it and work there sensibly? Tell us your car, the amount and whether it has run, and you will get a straight answer instead of a range. Not time-critical, with the car at home and going nowhere? Then is fine. Drain it then put fresh diesel in — that's the tip you'll get, generally from someone certain, and it's half right. Do exactly that to a diesel Vauxhall Astra close to Seaton Rangers and it would start, which is what makes the advice sound sensible. What occurs next is the problem: the motor straight away draws the petrol still sitting in your filter and the feed lines straight back through your pump, since emptying a tank does nothing about fuel that has already left it. Phone us instead. We flush the system and take the filter off where the vehicle has a serviceable one, which is the difference between the car being put right and the vehicle only starting. ## Petrol in diesel: frequent queries around Low Seaton ## Can you do a fuel drain at a petrol station around Low Seaton? Yes, and it is where a fair share of this work gets done. Routinely, provided the site agrees: BP, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our technicians can work in that place is something our engineers answer straight away. ## How much petrol is too much for a diesel? Whether your motor has run counts far more, though the ratio matters too, rather than the litres. A nearly empty tank with five litres in it, against a full one with the same five: separate scenarios, certainly. Either way, the work required comes down to one thing, which is whether the fuel system has had that mixture sucked through it. ## I put petrol in my diesel and drove the car. What now? Pull over somewhere sensible, turn off, and leave it off. Driving is what moves the trouble from your tank into your pump and injectors — but it's fixable a lot more frequently than motorists expect, and the single most helpful thing you can do now isn't restart the vehicle. ## My warranty — does a fuel drain void it? A manufacturer's warranty withstands a drain and flush done to a correct standard, which is no modification at all. What is likelier to start a disagreement is a diesel that has been run on petrol. One more reason for the engine to stay off. ## Two-stroke oil in the tank, and then home? What petrol has weakened isn't restored by two-stroke oil, which is an old remedy for a separate problem. So no. Afterwards? Still petrol in your tank, and a pump that has to cope with the stuff. ## Does petrol in a diesel have to go to a main dealer? No. Our technicians drain and flush the car wherever it is, so there's no need to take it to a franchised dealer. ## You, and your vehicle, still together? The engine remains off. If you have already driven the vehicle, pull over somewhere safe, switch it off then keep it off. This is recoverable from a lot more commonly than drivers fear, and a stationary, cold motor is the best place to be in. Throughout Cumbria and in Low Seaton: mobile fuel draining, at home or on the forecourt or at the roadside.
