Charlton Kings: Put Petrol in a Diesel Car?
With that tank still carrying the petrol and the engine not yet started, nearly every job needs only a drain, so keep the engine off. That result is determined in the minutes right after the fill-up, rather than by the amount that went in. Across Charlton Kings and the rest of Gloucestershire, Petrol in Diesel drains the vehicle and cleans it where it stands, whether at a roadside, on a drive or at a forecourt. Call us and we will explain what happens next before you attempt anything else.
Petrol in a diesel: what to do first
- Do not crank it. Started regardless? Then do not believe it. Diesel in a petrol motor usually won't run, so the person stops and the harm halts with them. Petrol in a diesel? It starts. It idles. It drives off normally, for several miles. Motorists get that confused. It is not fine — that fuel system is grinding every mile you cover.
- Two things, diesel: it combusts, and on the way through it keeps the injection pump and injectors greased. Petrol only does the one. That is why the ignition stays off also — turn it on and you often prime that system, and that's petrol exiting your tank for just those components.
- Do not tip diesel on top to water down it. A diesel fuel system doesn't tolerate petrol by percentage as that guidance presumes, and topping up takes out nothing — it merely hands you a fuller tank of the same blend. The octane makes no difference either: super unleaded is simply petrol.
- We would sooner drive to an odd spot than have it started — so if you safely can, stay put. Nothing is quicker to handle than a motor that has never shifted. On the verge on Hearne Close, that means hazards on then leave the vehicle.
- A van turning up rather than circling depends on two things: a postcode beginning GL53 8, and whatever is closest to you with a label on it. Have both ready before you dial.
- Call 0333 366 0103. Anticipate three things — what got in, about how much, plus whether your car has been run. Those replies determine all that follows.
At the forecourt: clearing petrol from your diesel
A big part of this work is completed at a forecourt, because that is where it often begins. Our technicians work on station forecourts routinely, with the station's consent, so if you're still at BP that's normally where the drain happens.
Before the motor has fired — the forecourt is the single spot the mistake ends up halted. Everywhere else — a car park, a driveway, a lay-by — the vehicle was started and driven to get there, which means fuel was drawn from your tank, through your filter then into the high-pressure pump. That's not a disaster, and we can still sort it out where it stands. It does mean the fuel lines and the fuel filter need cleaning as well as your tank, and that is determined by the few seconds between seeing the till receipt and going for the key.
Clear of the petrol pump, the next customer can get by — so yes, let the staff help you push the vehicle. Well worth doing. Moving it four spaces doesn't merit cranking the engine.
How much fuel the pump has pulled is what we're truly asking — not how long ago any of that was. So the call our technicians hope for goes like this: diesel Renault Megane, a couple of litres of unleaded, a couple of miles done, now turned off at The Co-operative Food.
Each restart primes the fuel lines and draws more petrol past the filter and into your pump. So a wrongly fuelled diesel Skoda Octavia on the zig-zags by Charlton Kings Junior School is a nuisance, while the same car fired up three more times to be polite is a fuel system instead of a tank. Somebody will advise you to shift it out of the gateway and sort it out later. Please don't. Stay put, let people moan, and ring us.
Never risk it. The trip home from The Merryfellow is perfectly possible, which is precisely the trouble — a thinned tank does not stop a diesel starting or pulling away, it just wears the components your fuel is meant to protect. Phone us, then let the BMW 3 Series stay where it is.
Three things help when you phone from close to Stanton Suite: which side the filler is on, whether a van can park next to without blocking the road, and whether your engine has run since you filled up. On-street is the commonest location our technicians work, so the location itself is hardly ever the problem — we'd much rather deal with a cramped parking space than with a car that has been driven to somewhere more handy. We will drain the Dacia Duster, change the fuel filter where there's a usable one, flush the fuel lines then put fresh fuel through the full system, as by this point the worst of that is sitting in the lines instead of in your tank.
Somebody sure of themselves will tell you to drain the vehicle and put new diesel in. Half true, that. Try it on a diesel Vauxhall Astra close to Stocks and Whipping Post and your engine will start — which is exactly why it sounds like sense. Here is the catch: there is petrol left in the fuel filter and the feed lines, and the first thing the engine does is pull it back through your pump a second time. Emptying a tank achieves nothing about fuel that already left that tank. Phone us. The system gets purged, the fuel filter comes off where there is one worth removing, and that is what separates a repaired car from one that merely starts.
Charlton Kings and the towns next to it
Charlton Kings is a residential suburb, and so our vans head out to it and to the places near it on the usual rounds: East End, Ryeworth, Little Herberts, Ham and Moor End.
Our engineers still come. Those places above are just the closest neighbours, and a page is there for nearly all locations in Gloucestershire, so an absence from the list isn't an absence from the coverage. Phone and enquire instead of presuming, particularly if you are on the border or anywhere the satnav can't find.
See our map for the area included here. Your vehicle doesn't need to move to us. We operate throughout every bit of that — kerbside, forecourts, driveways, car parks.
Roadside stops around Charlton Kings
Some drivers have no suitable place to pull in at all. Set off, then realised? Ended up by the verge of Hearne Road, or sat in some lay-by with the hazard lights flashing? That is a routine call here. Not an unusual one.
Clear of the vehicle if it is not wise to wait there, beside it when it is. Never start it up to get to a nicer spot. It will go — a diesel on petrol generally obliges — and each mile of obliging draws the mixture deeper into the fuel system. Pressing on causes the car far more harm than a technician heading out to a tricky spot, and that is no bother for us.
Already run it? Petrol in a diesel over a couple of miles
under 5 miles out of Charlton Kings, the M5 is what counts now. Some distance along, and onto it in the first place: a wrongly fuelled diesel will often do both before anything feels wrong. What you get then is seldom a tidy stop. Power falls away, the idle turns rough, and there may be smoke.
The first safe junction is the one to take. Turn off there, then leave the restarting alone. Presume the worst of that on a long trip. Anything close to the under 10 miles to the closest city, and the contamination has been through your filter, through the pump, through the fuel injectors. Tell us when you ring. What our engineers bring differs.

What our engineers do when we arrive with you in Charlton Kings
- The answers alter the work, which is why our engineers ask before giving a price: what was put in, how much of it, and whether your motor has run.
- Our engineers drain your tank of the contaminated fuel.
- We purge your fuel lines and clean your filter, and so what is left in the fuel system is not what caused the issue.
- New diesel goes in, and then your system gets primed.
- When it's fired up, our engineers confirm it runs smoothly on clean diesel.
From there, you're ready to drive away. All of it is done where the vehicle is, so it never needs to be taken to a workshop, and when it has been spotted soon, lasting damage is very unusual.
A separate job: AdBlue in a diesel tank around Charlton Kings
Don't fire it up: that opening step applies whether what went in was AdBlue or petrol. What differs is this issue itself. The lubrication a fuel system depends on is stripped away by petrol, which thins your diesel. AdBlue is urea dissolved in water, and in a diesel tank it causes rust and build-up instead.
Often the more serious of the two, AdBlue — and the details sits on its own Charlton Kings page. Both are ours to handle.
What a petrol-in-diesel fuel drain will cost in Charlton Kings
Our engineers can't put one number on this page frankly, since this job is not one job. What moves it:
- Has it been run or driven? Nothing else matters for as much.
- Wrong fuel in, against what the tank holds — that proportion.
- Which was put in: unleaded or AdBlue.
- Access: the vehicle's position, and whether working on it there is safe for our van.
Tell us the car, the amount and whether it has run, and you'll get a straight answer instead of a range. If it's not time-critical — your car is at home and going nowhere — works too.
Petrol in diesel: frequent queries in Charlton Kings
Fuel drains on a Charlton Kings petrol station forecourt
A good portion of this work gets done there, so yes. Our technicians attend Esso and the other forecourts locally regularly, with the station's consent — tell us which one you're at when you phone and we'll tell you if we can work there.
Is there a sensible amount of petrol in a diesel?
Whether the engine has run matters a lot more, though the ratio matters too, rather than the litres. An almost empty tank with five litres in it, against a full one with the same five: distinct scenarios, certainly. Either way, the work required comes down to one thing, which is if the system has had that mix drawn through it.
Already driven it with petrol in the diesel? What now?
Somewhere safe, then stop, then turn off and leave it off. Driving takes the problem along — out of that tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one truly valuable thing left to you is not restarting the vehicle.
Is a fuel drain going to void my warranty?
A drain and flush carried out properly is not an alteration and doesn't invalidate a manufacturer's warranty. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Can I just add two-stroke oil and drive home?
No. It belongs to a distinct fault from a different era, and petrol has weakened something no oil of that kind replaces. That tank still has petrol in it later, and your pump still has to live with it.
Main dealers and petrol in a diesel
There's no need to take it to a dealership, as we drain and flush the car wherever it is.
You, and your vehicle, still together?
Keep it shut off.
If you have already driven the vehicle, stop somewhere sensible, turn it off and leave it off. A stationary, cold motor is the best position to be in, and this is recoverable from much more frequently than drivers fear.
