Thorley Street: Petrol in a Diesel Car? Here Is What Happens
Whatever you do, don't switch your motor on, even briefly, to shift the vehicle. Pause; leave it off. Emptied and flushed, just where it is: that's normally all an unrun diesel with petrol in it takes. Whether it remains that simple depends on the minutes to come more than on everything else. What follows is the sequence from here, wherever in Thorley Street you are.
Minute one: petrol in a diesel, motor off
Go through the following in order, before you do anything else.
- Take the keys out. Even the ignition on its own can prime your fuel system, pulling petrol out of your tank to exactly the components it damages, and so keep the car off wholly.
- A bigger tank of the same mixture is all topping up gives you, because it removes nothing. So no more diesel.
- Near moving traffic? Then your hazards go on before anything else, and so your car is simple to see.
- Off the pump by hand. On a forecourt, get the staff to help you push the vehicle clear of the pump. Do not start the car to shift it, however short the way.
- Hold on to your receipt. It says which fuel got in plus about how much, which is the first thing we'll ask.
If you were still on the move when you noticed, stop somewhere sensible instead of pushing on for the services — on the M11, under a mile from Thorley Street, that means the next junction. Step one comes next.
The fork in every Thorley Street fuel drain: has it run yet?
Everything after this point rests on one answer.
Engine never run at all?
- That petrol is still in that tank and nowhere else.
- Where your car stands is usually where the work happens: a drain, then a flush.
- No place is better, and it is why the first step counts so much.
If it's been started, even for a second:
- Some petrol has left your tank already, gone through your filter, and got into the fuel lines.
- A bigger run carries it all the way to the high-pressure pump and your injectors.
- The job expands with the distance — lines rinsed, filter seen to, sometimes more.
That line falls there because diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol does not. Petrol sitting in a tank harms nothing. Pump that petrol, though, and it grinds down the very parts that move it.
Thorley Street, petrol in a diesel: have these ready before you call
Whether the technician goes round or finds you comes down to a little preparation.
- The best start is a postcode — one starting CM23 4 — for where you are.
- A road name helps: Whittington Way, say, or whatever street you have stopped in. A car park does the trick too.
- What a car park serves is the easiest way to find it, and so say the landmark — such as the one outside Sainsbury's.
- The make and model of the car, and the fact it is a diesel.
- Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own Thorley Street page.
- The amount: the receipt's litres, or else how long you had the nozzle in.
- If it's run, how far plus how heavily — and whether it's run at all.
- The owner may have to authorise this work under some hire or company contracts — so it is faster to settle whose vehicle it is before our technicians arrive.
Then ring 0333 366 0103. If it can wait — your car is at home with going nowhere — works too.
Thorley Street fuel drain on its way? Whilst you wait
The wait is where well-intended help does the harm. Hold to these.
- Stay with the car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it.
- No one starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a couple of yards.
- No additives. Two-stroke oil, injector cleaner, something from the boot — none of it takes the petrol back out.
- Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank stays where it is regardless.
- Not for your radio, not for your windows: the ignition stays off.
When our van gets there: the fuel drain, step by step
- Our price comes after three questions, not before them — what got in, how much, and if it has run — since those answers decide the job.
- Draining it's how that mixture gets taken from the tank.
- Rinsing the lines comes next, because a car that ran has petrol past your tank, inside the lines themselves.
- Then the fuel filter: swapped where there's a serviceable one, cleared where there is not.
- The fuel system is primed with fresh diesel.
- We start it only after fresh diesel has gone in and primed the fuel system, then check that it is running smoothly.
We remain until it's running on new diesel. Permanent damage is very uncommon if it has been caught early, so the vehicle can go straight back to normal use.
Thorley Street, after the fuel drain: back on the road
- Started on new diesel, it needs nothing special of you. Simply drive normally.
- Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over then ring us back.
- Keep your documents. A hire firm, a fleet manager or an insurer may ask what was done.
- Read the label on the petrol pump next time, not the colour of the handle.
