--- title: Fuel Drain in Abbey Gate — Petrol in a Diesel Car canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/abbey-gate-devon/ location: Abbey Gate county: Devon latitude: 50.772780 longitude: -3.001180 service: Petrol in a Diesel Car updated: 2026-10-15 --- # Petrol in a Diesel Car in Abbey Gate Do not fire up the motor. If the fuel is still inside that tank and the engine has not yet run, a drain is nearly always all it requires — and that gets decided in the next few minutes, not by how much got in. Petrol in Diesel drains and cleans wrong-fuelled vehicles where they stand, all over Abbey Gate and the remainder of Devon, on the forecourt, by the roadside or on a drive. Our technicians will explain what the next part is. Ring us — that comes ahead of all else. ## The next five steps: petrol in a diesel - Feed a petrol motor diesel and it will generally refuse to run at all, and so the driver stops there and so does the harm. Feed a diesel petrol and the engine starts, it ticks over, it pulls away — fine for a couple of miles. Most people have that backwards, which is the thing they get wrong about petrol in a diesel specifically. So do not fire it up. And having started, do not believe it: your fuel system is wearing while you drive. - Diesel ignites, and before it combusts it greases — the injection pump, those injectors. Petrol handles only the burning. So leave the ignition be too: turning it on is often sufficient to prime the system, and priming moves petrol from your tank into exactly those parts. - Never water down it. Diesel added on top removes nothing, and so all you get is more of what was already there, since percentage is not how a diesel fuel system handles petrol. Super unleaded? Simply petrol. The type makes no difference. - We'd sooner get to an odd spot than have it started — so if you reasonably can, stay still. Nothing is quicker to sort than a vehicle that has never shifted. On the verge on Woodbury Lane, that means hazards on then keep the vehicle. - Have your whereabouts ready before you ring. A postcode that starts EX13 5 and whatever is nearest to you with a label on it is the difference between our van turning up and the van circling. - What was put in, roughly how much, and also whether the engine has run — those three details settle your whole call-out. Call 0333 366 0103 and tell us. Quarter past eight, a quick fill on the road in, and the penny drops close to eleven — by then the diesel Volkswagen Passat has been parked at Axminster for three hours. Call us and leave the vehicle right where it is. The drive in is the thing that is key now, because diesel has two tasks on its way through a motor: it ignites, and before it ignites it greases its injection pump and its injectors. Petrol handles the first and not the second. So those couple of miles were travelled with your pump working on a fuel that had given up a lot of the protection it is made for — which is why the thing we ask is how far you travelled, not how long your car has been sitting. ## Forecourt draining for petrol in a diesel Forecourts are where this job mostly kicks off, and where a fair share of it ends. The drain usually gets done right there. Still on the forecourt at Tesco? Given the owner's agreement, that is somewhere we work, and often. Nowhere except a forecourt can the mistake be halted with the motor still untouched. Our technicians can still deal with it where it is, even away from the pumps. In a car park, on a driveway or in a lay-by, the car has been switched on and moved there, and that sucked fuel through the fuel filter then into your high-pressure pump, right from that tank. None of that is a calamity, but the flush then has to reach past that tank to the lines and the filter, and the few seconds between checking your receipt and going for the key are what determine that. The attendants will normally offer to roll it clear of the pump so the next driver can get through. That's worth doing. Cranking it just for four car lengths? Not a chance. ## Do we reach your side of Abbey Gate? Axminster, Wyke Green, Sector, Trill, Millway Rise — every one of those on our journeys that carry us over to Abbey Gate itself, a small village. If yours is not on that list it does not mean we never come — there are dedicated pages for most towns in Devon, and the ones mentioned above are just the immediate neighbours. Ring us and check rather than guessing — county lines particularly, and anywhere the satnav may get wrong. That map is the area this page includes. All of that is territory our technicians work: a roadside, a forecourt, a drive, a car park. You do not drive the vehicle anywhere. ## Stranded by the roadside anywhere around Abbey Gate? Not everyone has a suitable spot to stop. If you noticed after setting off and ended up along the verge on Athelstan Close, or in a lay-by somewhere with the hazards on, that's a common call for us rather than an odd one. Whether you wait with the car or stand away from it turns on if sitting in it is sensible. Don't start up your engine to limp the vehicle somewhere better — a diesel running on petrol will often oblige, and every mile it obliges for is drawing the blend further into the fuel system. A technician driving to an awkward place is no trouble for us, and it's much better for the vehicle than driving on. You drive off at the end, once our technicians have fired it up and confirmed it runs properly on fresh diesel, with your system primed. Before that, in the car park by Axminster Inn, the tainted fuel comes out of that tank, your lines get rinsed and the fuel filter comes off where your Peugeot 3008 has a serviceable one. Everything begins with three questions when our technicians get to the vehicle: what was put in, how much of it, and whether it has been started since. ## So you've run it? Petrol in a diesel over a couple of miles This is where the local M5 comes into it — under 25 miles from Abbey Gate. A misfuelled diesel will frequently get you onto it and some way along before anything feels wrong, and the signs when they arrive are normally a drop in power, a lumpy idle and smoke rather than a neat stop. The next safe junction is the one to take. Turn off there, then leave the restarting alone. Long drive? Anything close to the under 25 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of it got to by the petrol. Say that on the call, since it affects what goes in our van. Your pump isn't turning, and so whatever the diesel Audi A3 did on the way to Jubilee Field, none of it is happening now. Nothing is getting worse while it waits. Take your time over this — but don't drive it home to buy any. ## All about Abbey Gate Abbey Gate is a locality situated on the riverside in Devon, with a relatively low elevation of 55 metres. Abbey Gate lies near the cities of Exeter and Axminster, and is characterized by its predominantly detached housing stock. Abbey Gate is a small community, with a population of around 894 residents, and is located approximately 23.5 miles from Exeter. Abbey Gate benefits from its proximity to the surrounding countryside and nearby places like Wyke Green and Sector. ## Once we reach you around Abbey Gate: what happens - Our technicians ask first, price after. What was put in? How much? Has your engine run? Those answers alter what the work actually is. - The contaminated fuel comes out of your tank. - Fuel lines are flushed through and your filter cleaned, leaving nothing in the fuel system that caused any of this. - We pour fresh diesel in and bleed the system. - When it is fired up, our technicians confirm it runs correctly on clean diesel. At that point it's ready to set off. There is no need for a workshop at any point, because the work is all done where the car is, and when it's noticed soon, long-term damage is very uncommon. ## AdBlue in your diesel tank instead, in Abbey Gate? Do not crank it: that first step stands whether what went in was AdBlue or petrol. What changes is this problem itself. Weakened diesel, and no lubrication left for your fuel system that relies on it. That's petrol. Urea in water, AdBlue, and in a diesel tank that brings corrosion and residue. Often the more serious of the two, AdBlue — and the full story lives on its own Abbey Gate page. Both are ours to handle. Turn off where you have stopped, and do not start it to find somewhere better — by Newenham Abbey or anywhere at all. Knocking, a ragged idle, white smoke and a soft throttle are a misfuelled diesel Citroen C3 telling you what's wrong. ## Abbey Gate costs for a petrol-in-diesel drain One figure would not be fair here, since this is not one job. These are the things that move it: - Whether your engine has been started or driven. This is the big one. - How much of the wrong fuel was put in, judged against how much the tank holds. - AdBlue or unleaded, whichever went in. - Access: the car's position, and if working on it there is sensible for a technician. A clear answer rather than a range is what you get for telling us three things: your car, the amount, and if it has run. Not urgent, with the vehicle at home and going nowhere? Then does this job. Drain it then put clean diesel in — that's the tip you will get, usually from someone sure of themselves, and it's half true. Do precisely that to a diesel Kia Sportage near Axminster Guildhall and it would start, which is what makes the tip sound reasonable. What happens next is the problem: your engine straight away draws the petrol still resting 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. Ring us instead. Our technicians flush your circuit and take your filter off where your vehicle has a workable one, which is the difference between the car being repaired and your car simply starting. ## Questions our engineers hear about petrol in diesel in Abbey Gate ## I'm on a forecourt in Abbey Gate. Can you drain the vehicle here? Much of what we do happens nowhere else. So yes. Often, provided the site agrees: Harvest Energy, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether we can work in that spot is something our technicians answer on the spot. ## How much petrol in a diesel is too much? Proportion settles it rather than litres — and more than either, whether the engine has run. An almost empty tank with five litres in it, against a full one with the same five: distinct scenarios, definitely. Either way, the work needed comes down to one thing, which is if your fuel system has had that mix pulled through it. ## I drove the car after putting petrol in my diesel. What next? Turn off somewhere sensible, and keep it that way after you stop. Driving is what takes the problem from the tank into your pump and injectors — but it's fixable a lot more regularly than motorists expect, and the single most useful thing you can do now isn't restart the vehicle. ## Is a fuel drain going to void my warranty? A manufacturer's warranty outlasts a drain then flush done to a correct standard, which is no alteration at all. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it turned off. ## Could I put some two-stroke in and just drive? Two-stroke oil solves a separate fault, 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 put up with it. ## Does petrol in a diesel have to go to a main dealer? Not at all. Our engineers drain and clean your car wherever it is, so there's no need to bring it to a dealership. ## Standing next to it? Leave the car turned off. Already driven it? Then pull over somewhere sensible, switch off, then let the vehicle stay that way. Cold, parked, going nowhere: that's the best place to be in. Motorists fear this much more than they need to.
