Charlton: Put Petrol in a Diesel Car?
Do not fire up the motor. If the fuel is still sitting in that tank and your engine has not yet been started, a drain is almost always all it takes — and that is decided in the coming few minutes, not by how much was put in. Petrol in Diesel drains and cleans wrongly fuelled vehicles where they are, all over Charlton and the remainder of Surrey, on the forecourt, at the roadside or on a private drive. Ring us before everything else begins, so you'll see what follows from there.
Your next five minutes: petrol in a diesel
- Never crank it — and don't depend on it when it runs. That is the part people get wrong about petrol in a diesel specifically. A petrol engine given diesel normally just can't run, so the person stops and the harm ends with them. A diesel given petrol usually starts, ticks over and moves off without complaint for a couple of miles. It's not okay. It is wearing that fuel system whenever you drive.
- Switching your ignition on commonly primes that system, and priming is what pulls petrol out of your tank then into the pump and injectors. Those are the components diesel keeps lubricated on its way through, before it combusts. Petrol handles the burning and none of the protecting. Leave the car's ignition off.
- Don't add diesel on top to dilute it. A diesel fuel system does not tolerate petrol by percentage in the way that guidance suggests, and topping up gets rid of nothing — it merely leaves you a fuller tank of the same mixture. The type makes no difference either: super unleaded is simply petrol.
- We'd sooner travel to an odd location than have it started — so if you safely can, stay put. Nothing is easier to handle than a vehicle that hasn't shifted. On the verge on Hetherington Road, that means hazards on then leave it.
- Our van arriving rather than circling depends on two things: a postcode beginning TW17 0, and whatever is closest to you with a sign on it. Keep both prepared before you ring.
- Call 0333 366 0103. Tell us what was put in, approximately how much, and if the car has fired. These three details determine your whole visit.
Quarter past eight. A quick refuel on the drive in. Close to eleven it occurs to you, and by then your diesel Volkswagen Passat has sat at Upper Halliford for three hours. Ring us then keep the car where it stands. What matters is the trip in, as diesel both burns and — before that — lubricates your pump and your injectors, but petrol only ever combusts. Those couple of miles worked the pump on a fuel drained of a great deal of its protection, and no amount of standing in a car park adds any of it back. Hence the thing we ask about mileage instead of hours sitting, and hence the advice to leave your keys be till our engineers get there.
Each restart primes the lines and pulls more petrol past the fuel filter then into the pump. So a misfilled diesel BMW 3 Series on the zig-zags at Littleton CofE Infant School is a hassle, while the same vehicle fired up three more times to be courteous is a fuel system instead of a tank. Somebody will advise you to move the car out of the gateway and deal with it later. Please don't. Stay put, let people moan, then call us.
You set off at the end, once our engineers have started it and confirmed it runs smoothly on fresh diesel, with the system bled. Before that, in the car park by The Harrow, the tainted fuel comes out of the tank, the lines get rinsed and the fuel filter comes off where your Dacia Duster has a replaceable one. It all starts with three questions when our technicians reach the vehicle: what was put in, how much of it, and whether it has been started since.
Petrol in a diesel does its damage as a share, which is the reason our engineers ask at all: the same few litres resting in an almost empty tank make a far stronger mix than they would in a full one. And petrol is rated on how well it resists igniting under pressure — the opposite of what a diesel needs — so a stronger blend rattles more, smokes more, goes flatter. None of which means you need an answer ready. Nearly no one knows how full the tank was in a vehicle collected two days ago, and we work that out there. Do phone the hire or company firm first, though: some agreements want them to authorise the work, and that is far quicker settled before than after. Then ring us about the Audi A6 by Upper Halliford Community Hall.
What happens next is the problem. Your engine straight away draws the petrol left waiting in the filter and the feed lines back round through your pump a second time, since emptying a tank does nothing about fuel that has already left it. Drain it and put clean diesel in, someone certain will tell you — and that tip is half right, since do it to a diesel Ford Kuga parked up, St Andrews Baptist Church say, and the thing starts, which is what makes it sound sensible. Phone us instead. Our technicians flush the system and take the filter off where the vehicle has a workable one, and that's the difference between the car being fixed and the vehicle just starting.
Can petrol be drained from a diesel at the forecourt?
Forecourts are where this work often begins, and where a fair chunk of it ends. The drain usually happens on the spot. Still on the forecourt at Esso? Given the owner's consent, that's somewhere our technicians work, and often.
At a forecourt, it is spotted with your engine never fired, and nowhere else does it. We can still sort it out where it is, even away from the forecourt. In a car park, on a driveway or in a lay-by, your car has been started and moved there, and that pulled fuel through the fuel filter then into the high-pressure fuel pump, right from the tank. None of that is a catastrophe, although the flush then has to go past your tank to your lines and the filter, and the few seconds between seeing the till receipt and reaching for the key are what decide that.
Move the car out of the way if the staff offer, and they usually will. The next motorist gets by the petrol pump, and that is worth doing. Starting the car to move four car lengths isn't.
Can we serve your side of Charlton?
As a village, Charlton has a steady call, while the villages nearby come with it on the same run: Littleton Common and Littleton, Upper Halliford and Shepperton Green, Shepperton.
If yours isn't on this list it does not mean we don't come — there are dedicated pages for the majority of towns in Surrey, and the ones named above are just the nearest neighbours. Assuming is the habit to skip, particularly on the boundary or anywhere a satnav fails. Contact us and enquire.
This map shows the area the page includes. Roadside, forecourt, drive, car park: all of it is ground we serve, and none of that needs the vehicle to move to us.
Stranded on the kerbside around Charlton
Not everyone gets a sensible place to pull in. A common call for us rather than an unusual one: realised after setting off, ended up along the verge of Charlton Road or at a lay-by with your hazards going.
Sit with the vehicle if it is sensible to sit inside, yet clear of the car when it is not. Don't restart it to reach a nicer spot. It will go — a diesel on petrol normally obliges — and each mile of obliging drags the mix deeper into your fuel system. However difficult the place, it's no bother for us to get to it, and that is much better for your car than driving on.
Petrol in a diesel, and your car has travelled
This is where the local M3 comes in — under a mile away from Charlton. A misfuelled diesel will usually get you onto it and some distance along before anything seems wrong, while the signs when they appear are typically lost power, an uneven idle and some smoke instead of a neat stop.
The next safe junction is the one to take. Turn off there, then leave the restarting alone. It alters what our engineers bring, so say so when you phone: on a longer drive — anything near the under 25 miles to the nearest city — take it the contamination has been through your filter, the pump and your injectors.
About Charlton
Charlton is a village in Surrey, situated on the lakeside at a low elevation of around 14 metres. Charlton lies within the South East region, approximately 15 miles from London, and is near the neighbouring communities of Littleton Common, Littleton, and Upper Halliford. Charlton has a population of around 1020 residents, predominantly living in semi-detached housing.
Once we arrive with you in Charlton: what follows
- We check what got in, how much, and whether the engine has run. The responses change the work, which is why our technicians ask before pricing.
- Our technicians empty the tank of all the polluted fuel.
- Lines purged, filter cleaned. Whatever is left later isn't the thing that started the trouble.
- Clean diesel goes in, and then the fuel system gets primed.
- Once it is fired up, our engineers make sure it runs smoothly on clean diesel.
Then it's ready to set off. Long-term damage is very uncommon when it has been caught early, and since all of it is done where your car is, it never needs to go to a garage.
A separate problem: AdBlue in a diesel tank around Charlton
Never fire it up: that first instruction holds whether what went in was AdBlue or petrol. What changes is this issue itself. Weakened diesel, and no lubrication left for the system that depends on it. That is petrol. AdBlue is urea dissolved in water, and in a diesel tank it causes rust and deposits in its place.
Usually the more serious of the two, AdBlue — and the detail sits on its own Charlton page. Both are ours to deal with.
How much is a petrol-in-diesel drain around Charlton?
Honestly, no single number fits on a page like this. This job varies. Here is what moves it:
- Has it been started or driven? Nothing else counts for as much.
- How much of the wrong fuel got in, weighed against how much the tank takes.
- Which went in: petrol or AdBlue.
- Where is it? And can a van get to it and work there sensibly?
The car, the quantity, whether it has run — give us those and the answer comes back straight rather than as a range. For the vehicle at home that is going nowhere and isn't time-critical, works too.
Petrol in diesel queries from Charlton motorists
Can you do a fuel drain at a petrol station around Charlton?
A fair share of this work happens there, so yes. Tell us which one you are at when you phone and we will tell you whether our technicians can work there. With the station's permission our engineers visit BP and the other forecourts locally regularly.
A few litres of petrol in a diesel — too much?
Proportion decides it rather than litres — and more than either, whether your engine has run. A nearly empty tank with five litres in it, against a full one with the same five: distinct situations, definitely. Either way, the work needed comes down to one thing, which is whether the system has had that mixture drawn through it.
Petrol in my diesel, and I have driven the car
Turn off somewhere safe, then keep it that way after you stop. Driving shifts the problem along — out of the tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one genuinely useful thing left to you is not restarting the vehicle.
Is a fuel drain going to void my warranty?
It's not an alteration, and so a drain and flush carried out correctly doesn't cancel a manufacturer's warranty. Running a diesel on petrol is the thing likelier to cause an argument with one, which is another reason to leave the car turned off.
Could I put some two-stroke in and just drive?
Two-stroke oil solves a distinct problem, and an old one at that. Nothing it does puts back what petrol weakened. No. Your tank still has petrol in it later on, and the pump still has to live with it.
A main dealer for petrol in a diesel — essential?
Wherever your car is, our technicians drain and clean it there, so a drive to the main dealer does not come into it.
Is your car still with you?
That engine stays off.
Already driven it? Then pull over somewhere sensible, switch off, then let the car stay that way. This is recoverable from far more regularly than drivers assume, and a stationary, cold vehicle is the best place to be in.
