Coton in the Elms: Put Petrol in a Diesel Car?
If you have not fired up the engine yet, don't. A drain and nothing else is almost always what a motor requires while the fuel is still inside your tank and the engine has not yet been started, which is why it's the coming few minutes that count, not how much went in. Petrol in Diesel goes to the vehicle wherever it has ended up in Coton in the Elms or the remainder of Derbyshire, on the forecourt, by the roadside or on a private drive, and drains and cleans it there. Our engineers can tell you what the next stage will be. Ring us — this comes ahead of anything else.
Your next five minutes: petrol in a diesel
- Never crank it — and never depend on it if it runs. That is the bit drivers get wrong about petrol in a diesel specifically. A petrol motor given diesel typically just will not run, and so the person stops and the wear halts with them. A diesel fed petrol typically starts, idles and drives off quite happily for a few miles. It isn't okay. It is wearing your fuel system while you drive.
- Diesel ignites, and before it combusts it greases — that high-pressure pump, its injectors. Petrol does only the burning. So leave the ignition off too: flicking it on is often enough to prime the system, and priming draws petrol from the tank into just those components.
- That guidance supposes a diesel fuel system tolerates petrol by percentage. It won't. Tip diesel on top and nothing at all is removed; what you end with is a bigger tank of the same mix. And no, the type makes no difference — super unleaded is simply petrol.
- Stay put if it is sensible to. Hazards on, engine off, keep it. Wherever you have stopped — the verge on Church Street, anywhere — a difficult place for us beats a started motor, and nothing is simpler for us to handle than a vehicle that never shifted.
- The van showing up rather than circling hinges on two things: a postcode that starts DE12 8, and whatever is closest to you with a sign on it. Keep both prepared before you ring.
- Three replies settle the entire call-out: the liquid you poured in, the ballpark measure involved, plus if it has been turning since. The line is 0333 366 0103.
Do not run it home. Petrol-thinned diesel has gone through the injection pump in real quantity on the drive in, and the drive back would close to double that for nothing at all. Ring us — the platform is okay. There is no need to stand over your Volkswagen Golf at Burton-On-Trent whilst the work happens, and we'd very much rather hear from you tonight than discover on Monday.
Put diesel in a petrol car and generally it won't run, and so the driver stops there and the damage stops with them. Swap it — petrol into a diesel — and the car fires up, ticks over and drives off as though nothing had happened, while your high-pressure pump works without the protection the fuel is meant to be providing. That's the catch, and it's why the diesel Skoda Octavia will have seemed completely usual coming back from Coton-in-the-Elms Cof E Primary School. They always do. From behind the wheel there is nothing to alert you about, and so nothing warns you. Ring us with roughly how far you travelled, and how hard; the second answer matters more than the first.
Do not chance it. The journey home from The Black Horse is perfectly possible, which is exactly the trouble — a diluted tank does not stop a diesel starting or pulling away, it just wears down the parts your fuel is supposed to lubricate. Call us, and let the Peugeot 308 stay where it sits.
Diesel has to be viscous enough to seal the precision components it flows through, and petrol thins it. That's the full mechanism, and it accounts for the usual Coton in the Elms Recreation Ground call: a diesel Audi A4 that drove out there without fuss and came back down on power, uneven at idle, maybe smoking a little. A diesel injection system works hydraulically as well as chemically — it needs the fuel to hold pressure, not merely to burn — so when the fuel dilutes, pressure that should build and stay built starts leaking past gaps instead, and the motor gets a weaker, later, less even delivery than it was built about. None of that is your engine failing, which is the part worth hearing: it's the fuel no longer acting like diesel, and it stops when the fuel is sorted.
Switch off where you have stopped, and do not restart it to find somewhere better — by Coton in the Elms Community Centre or anywhere at all. Clattering, an uneven idle, white smoke and a limp throttle are a misfuelled diesel Mercedes E-Class telling you what is wrong.
Can petrol be drained from your diesel at the forecourt?
The job begins at a pump, typically. Often enough it finishes there as well. If you are still on the forecourt at the nearest petrol station, that is generally where this drain happens — we work on petrol station forecourts regularly, with the owner's permission.
At the forecourt, this gets stopped with the engine never run, and no place else does that. Everywhere else — a car park, a drive, a lay-by — your car was switched on and moved to get there, which means fuel was pulled from the tank, through the fuel filter then into the high-pressure pump. That is not a catastrophe, and we can still sort it out where it is. It does mean the fuel lines and your filter need flushing as well as that tank, and that is settled by the few seconds between seeing your receipt and going for the keys.
Away from the pump, the next driver can get by — so yes, let the staff help you push the vehicle. Very much worth doing. Starting the car to shift four car lengths is not.
Coton in the Elms plus the villages beside it
As a village, Coton in the Elms sees a regular call, whilst the areas close by go along on that same round: Rosliston and Caldwell, Lullington and Linton, Coton Park.
There are separate pages for nearly all locations around Derbyshire, and the ones named above are merely the immediate neighbours — so yours being absent from that list says nothing whatsoever about whether our engineers come. Ring us and enquire instead of guessing, above all if you are on the boundary or anywhere a satnav can't find.
The map shows the ground this page includes. The lot is ground our engineers work: a kerbside, a forecourt, a private drive, a car park. You do not move your car anywhere.
Kerbside breakdowns in Coton in the Elms
Some people have no suitable spot to pull over whatsoever. If you realised after setting off and landed on the verge beside Glebe Close, or in a lay-by somewhere with the hazards flashing, that's a normal call for us and not an unusual one.
Remain with the car while it is safe to be there, and clear of the vehicle if it's not. It will usually oblige. A diesel running on petrol limps along perfectly willingly, and that's the catch: start it up to reach somewhere better and the mixture goes further into the system with every mile travelled. Our van driving to an inconvenient location is no problem for us, and it is a lot better for the car than carrying on.
Run it already? Stop, then check below
Here is where the local M42 comes into it — under 5 miles away from Coton in the Elms. It will usually get you onto it, and some way along, before you feel a thing. Then it's smoke, a lumpy idle and power falling away — not a tidy stop. Misfuelled diesels rarely give you one of those.
The first safe exit is the one to take. Switch off there, then leave the restarting alone. Long drive? Anything approaching the under 10 miles to the closest city and you should presume the lot — filter, pump, injectors, all of that arrived at by the mixture. Say that on the call, since it alters what goes in the van.
Coton in the Elms itself

What follows when our engineers get to you in Coton in the Elms
- The replies shape the work, which is why we ask before quoting: what went in, how much of that, and if the motor has run.
- Away comes the polluted mixture.
- Lines cleaned, filter cleared. Whatever is left afterwards isn't the thing that caused the trouble.
- Priming follows, once fresh diesel is in.
- After it is started, we check it runs smoothly on new diesel.
The car is then ready for you to pull away. There's no need for a workshop at any stage, as the work is all done where the vehicle is, and when it's caught early, long-term damage is very rare.
AdBlue in a diesel tank in Coton in the Elms is a separate job
If what was put in was AdBlue instead of petrol, the first instruction is unchanged — don't start the car — but this problem isn't. Petrol does two things to diesel: weakens it, and takes away the protection your fuel system relies on. Rust and residue are what a diesel tank ends up with instead, as AdBlue is urea dissolved in water.
AdBlue removal in Coton in the Elms has a page of its own with the full story on it, including why it's usually the more significant of the two. Our technicians deal with both.
What a petrol-in-diesel drain will cost around Coton in the Elms
We can't put one number on this page truthfully, since this job isn't one job. What shifts it:
- Whether the motor has been run or driven. This is the big one.
- How much of the wrong fuel was put in, measured against how much your tank can hold.
- Which went in: unleaded or AdBlue.
- Where is it? And can our van get to it and work there safely?
A firm answer instead of a range is what you get for telling us three things: your vehicle, the amount, and if it has run. If it's not urgent — your car is at home and going nowhere — works too.
Petrol in diesel: common queries in Coton in the Elms
Fuel drains on a Coton in the Elms petrol station forecourt
Plenty of what our engineers do happens nowhere else. So yes. Tell us which one you're at when you ring and we will tell you if our engineers can work there. With the site's consent our technicians attend JET and the other forecourts nearby routinely.
How much petrol in a diesel is too much?
Whether your motor has run matters far more, though the proportion counts too, instead of the litres. An almost empty tank with five litres in it, against a full one with the same five: separate situations, of course. Either way, the work required comes down to one thing, which is if the fuel system has had that mixture pulled through it.
Already driven it with petrol in your diesel? Now what?
Somewhere sensible, then stop, then turn off and keep it off. Driving shifts the issue along — out of that tank, into your pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one truly helpful thing left to you is not restarting it.
Is a fuel drain going to void my warranty?
No. Carried out properly, clearing and flushing is no alteration at all, and the warranty from your manufacturer is unaffected by it. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.
Can I just add two-stroke oil and drive home?
No. Two-stroke oil is an old workaround for a different problem and it does not replace what petrol has thinned. After that? Still petrol in your tank, and a pump that has to cope with the stuff.
Do I need a main dealer for petrol in a diesel?
You don't need one. The vehicle is drained and flushed wherever it is, with no need to bring it to a franchised dealer.
Still with your car?
Leave the engine turned off.
Already driven it? Then pull in somewhere sensible, switch off, then let it remain that way. This is recoverable from far more regularly than people fear, and a still, cold vehicle is the best place to be in.
