Put Petrol in a Diesel Car in West Town? Don't Start It
Never start the engine. If the fuel is still inside that tank and the engine has not been started, a tank drain is almost always all it requires — and that is settled in the coming few minutes, not by how much went in. Petrol in Diesel drains and cleans wrong-fuelled vehicles where they sit, throughout West Town and the rest of Devon, on the forecourt, by the roadside or on a drive. Contact us so we can show you what comes next before you try any more.
Petrol in a diesel: what to do now
- Give a petrol motor diesel and it will generally fail to run at all, so the motorist stops there and so does the wear. Feed a diesel petrol and the car starts, it idles, it pulls away — all right for several miles. People have that reversed, which is the bit they get wrong about petrol in a diesel specifically. So don't crank it. And having started, don't trust it: the fuel system is wearing whenever you drive.
- Switching the ignition on often primes that system, and priming is what pulls petrol out of your tank and into your pump and injectors. Those are the components diesel keeps lubricated on its way through, before it ignites. Petrol handles the burning and none of the lubricating. Leave the car's ignition alone.
- Topping up clears nothing. It hands you a larger tank of the same mix, since a diesel fuel system doesn't cope with petrol by percentage in the way that guidance implies — so never put diesel on top to weaken it. Grade is irrelevant too: super unleaded is petrol.
- Stay put if it is wise to. Hazards on, motor off, keep it. Wherever you have stopped — the verge on Landscore, anywhere — an awkward place for us is better than a started engine, and nothing is quicker for us to deal with than a motor that never moved.
- Keep your location ready before you ring. A postcode beginning EX17 3 and whatever is closest to you with a sign on it is the difference between our van arriving and the van circling.
- Ring 0333 366 0103. Say what was put in, about how many litres, plus if the motor has started. Those three replies shape your whole call-out.
The trip in is what sucked weakened diesel through your pump. Sitting still has drawn nothing. Petrol in a diesel Renault Megane, parked at Crediton all day, waits dormant in that tank whilst it waits. Phone first — before the keys go in.
If you have put petrol in your diesel Skoda Octavia around West Town and you are now stranded at Morrisons with a boot loaded with shopping, phone us. Don't fire it up once more to leave that spot. We'll come out to you, empty that tank, flush the fuel lines then put new diesel in so you can drive away. A mile or so at gentle throttle uses little fuel, so these are usually the easy jobs.
Twenty to nine by Landscore Primary School, already late, and the receipt in your hand shows unleaded. Hazards on, engine off, phone us. Three miles in your Nissan Qashqai seems like nothing, but a diesel pump delivers fuel to demand — and a hurried morning dash asks for plenty.
Our technicians flush the lines instead of only clearing the tank, and the reason is that weakened fuel has already got to the filter and the pump: it was a start and a drive, however short. The distance truly assists — pulled off the forecourt, receipt read, a diesel BMW 5 Series parked up by Old Landscore School a couple of hundred yards later is about as well as this goes once the motor has turned. Phone us and leave it off.
Petrol in a diesel does its damage as a ratio, which is the reason we ask at all: the same few litres sitting in an almost empty tank make a far stronger mixture than they would in a full one. And petrol is rated on how well it withstands igniting under pressure — the opposite of what a diesel needs — so a stronger mix knocks more, smokes more, goes flatter. None of which means you need an answer prepared. Almost no one knows how full the tank was in a vehicle picked up two days ago, and our technicians work that out there. Do phone the hire or company firm first, though: some agreements want them to sign off the work, and that is far faster settled before than after. Then call us about the Volkswagen Polo close to St Lawrence Chapel.
On the forecourt: draining petrol from the diesel
It kicks off at the pump, generally. Quite often the work wraps up there too. If you are still at the forecourt at Shell, that is generally where this drain takes place — our technicians work on garage forecourts routinely, with the site's consent.
At a garage, the mistake is caught with the motor never fired, and no place else does it. Fuel sucked out of the tank and through your filter, right to your high-pressure pump, is what happens when the engine is switched on and your car is moved to where it is now: the car park, the drive or the lay-by, anywhere other than the forecourt. So the flush includes the fuel filter and your lines as well as that tank. That is still not a calamity, and our engineers deal with it where the car sits. What determines it is whether the key was reached for in the seconds after your receipt was read.
Clear of the petrol pump, the next motorist can get by — so yes, let the staff help you wheel the car. Very much worth it. Four vehicle lengths isn't worth a start.
Can we cover your corner of West Town?
As a residential suburb, West Town sees a steady visit, and its neighbours close by go along on that same journey: Westwood and Crediton, East Town and Salmonhutch, Fordton.
There are pages for most locations around Devon, and the ones mentioned above are just the nearest neighbours — so yours being left off the list means nothing at all about whether our technicians come. On the boundary, or anywhere your satnav struggles with? Phone and check rather than presuming.
The patch the page includes appears on our map. Kerbside, forecourt, driveway, car park: every bit of it is territory our engineers cover, and none of that needs the vehicle to come to us.
West Town: stuck wherever you pulled up
A chance to pull over anywhere sensible doesn't fall to everybody. A common call for us instead of an odd one: noticed after setting off, finished up along the verge of Western Road or in a lay-by with your hazards going.
Out of the car while it is not wise to be in it, with it when it is. It will frequently oblige. A diesel running on petrol limps along very willingly, and that's the catch: fire it up to reach somewhere better and the blend goes further into the fuel system with every mile covered. However tricky the location, it's no bother for us to get to it, and that's far better for the vehicle than pressing on.
Run it already? Pull over, and see this
Here is where the M5 comes into it — under 10 miles away from West Town. It will usually take you onto it, and some way along, before you feel a thing. Then it is smoke, a lumpy idle and power falling away — not a neat stop. Misfuelled diesels rarely give you one of those.
The first sensible exit is the one to take. Switch off there, and leave the restarting alone. Long run? Anything approaching the under 10 miles to the nearest city and you should suppose the lot — filter, pump, injectors, all of that reached by the contamination. Say that on the call, as it changes what goes in the van.
All about West Town
West Town is a suburban area in Devon, situated approximately 7.5 miles from Exeter and 161.1 miles from London, at an elevation of around 82 metres. West Town sits in a gently rolling inland landscape, near neighbouring communities such as Westwood and Crediton. West Town has a population of around 4095 people, predominantly living in detached housing. West Town is also located near East Town, with which it may share some local amenities.
What comes next when our technicians reach you in West Town
- Our engineers ask first, price after. What was put in? How much? Has the engine run? Those answers shape what the work really is.
- Your tank is emptied of it.
- Fuel lines are cleaned through and your filter cleared, leaving nothing in your system that created any of this.
- We put new diesel in and prime the system.
- After it's fired up, our engineers make sure it runs properly on new diesel.
That has the car ready to set off. Our engineers do all of this wherever the car has stopped, which means it never needs to be taken to a garage, and when it has been noticed soon, it's very rare for there to be lasting damage.
A separate matter: AdBlue in a diesel tank in West Town
If what went in was AdBlue instead of petrol, the first step is unchanged — don't fire it up — yet this problem is not. Diluted diesel, and no protection left for your fuel system that relies on it. That is petrol. Urea dissolved in water, AdBlue, and in a diesel tank that causes rust and deposits.
Our technicians handle both, and AdBlue removal around West Town has its own page with the details — including why it's frequently the more significant of the two.
West Town costs for a petrol-in-diesel fuel drain
One number would not be honest here, since this is not one job. These are the things that change it:
- This is the big one: whether your motor has been run, or driven.
- The tank's capacity, set against how much of the wrong fuel went into it.
- AdBlue or unleaded, whichever was put in.
- Access: the vehicle's position, and whether working on it there is sensible for a technician.
Tell us your car, the quantity and whether it has run, and you will get a straight answer instead of a range. Car at home, going nowhere, nothing urgent about it — is good for that.
Petrol in diesel: everyday queries around West Town
I'm on a forecourt in West Town. Can you drain it here?
A fair part of this work takes place there, so yes. Our technicians work at Green Earth Biodiesel and the other forecourts around town routinely, with the owner's permission — tell us which one you are at when you phone and we'll tell you if we can work there.
Is there a sensible quantity of petrol in a diesel?
Litres are not the measure. Proportion is, and much more than either, it counts if anything has been run. A nearly empty tank with five litres in it, against a full one with the same five: distinct situations, certainly. Either way, the work needed comes down to one thing, which is if your fuel system has had that blend sucked through it.
Already driven it with petrol in the diesel? Now what?
Turn off somewhere sensible, then keep it that way after you stop. Not restarting it is the single most valuable thing available to you now. Driving does shift the problem out of the tank then into your pump and injectors, yes, and it stays fixable a lot more frequently than drivers fear.
My warranty — does a fuel drain void it?
It's not a change, and so a drain and flush carried out properly does not invalidate a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause an argument with one, which is another good reason to leave the vehicle turned off.
Two-stroke oil in your tank, and then home?
No. Two-stroke oil is an old fix for a separate issue and it doesn't replace what petrol has thinned. Later on? Still petrol in the tank, and a pump that has to put up with the stuff.
Main dealers and petrol in a diesel
Wherever the vehicle is, our technicians drain and clean it there, so a drive to the main dealer doesn't come into it.
You, and your vehicle, still together?
Never switch your engine on again.
Driven it already? Then somewhere safe, stop, switch off, and no restarting the car after that. This is recoverable from a lot more commonly than drivers expect, and a still, cold car is the best position to be in.
