Deepweir: Petrol in a Diesel Car? Here Is What Happens
Stop. Engine off. Leave the car that way — no second on, no shifting it anywhere. Cleared and flushed, just where it sits: that is normally all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes ahead far more than on anything else. Here's the order of things from here, anywhere you're in Deepweir.
Motor off: minute one with petrol in a diesel
Work through these first, in this sequence.
- Pull your keys out. Even your ignition by itself can prime the system, drawing petrol out of your tank to precisely the parts it damages, so leave the vehicle alone wholly.
- No diesel on top. More fuel in removes none of that petrol — it only makes you with extra of the same mixture.
- Close to passing traffic? Then the hazards come on before everything else, and so the vehicle is easy to see.
- However short the distance, starting it to shift it is the thing to avoid. At a forecourt, roll the vehicle away from the petrol pump by hand instead, then ask the attendants to lend a hand.
- Which fuel, and roughly how much? Your receipt answers both, and that is where our questions start. Do not bin it.
On the M4, under a mile from Deepweir, the next junction is the location to come off; elsewhere, the first safe location to stop. Don't press on to the services. Then go back to stage one.
The fork in each Deepweir fuel drain: has it run yet?
What comes after this rests on one answer, and only one.
Not run, not even once:
- Only your tank has petrol in it so far.
- A drain and flush, on the spot, is usually the whole job.
- Being here is as good as it gets — which is the whole point of stage one.
If the engine has run, even for a moment:
- The lines and the fuel filter now carry petrol drawn from your tank.
- Run it further and the petrol reaches the injectors, having gone through the pump first.
- The farther it went, the larger this job — your lines, your filter, and now and then more besides.
That line falls there since diesel protects the high-pressure pump and your injectors on its way through them — and petrol does not. In the tank, left alone, petrol harms nothing. The components that shift it are wearing the moment petrol is being pumped.
Calling about petrol in a diesel from Deepweir: what to have ready
A little planning is the difference between a van that finds you and a technician that circles.
- NP26 5 plus the remainder of the postcode makes the ideal way to begin telling us where you are.
- Wherever you have pulled up, the road's name is useful — whether that is Osprey Drive or somewhere else — and so does the name of a car park.
- Car parks are found most easily by what they serve: tell us the one at Asda, and it's easy.
- The car. Make, model, plus that it is a diesel.
- What went in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Deepweir, so tell us which.
- How long the nozzle was in, or the litres on the receipt — either tells us how much.
- Whether it has run. Then if it has, how far and how hard.
- Sort who has the car ahead of when our engineers arrive: some hire or company contracts want the owner to authorise the work, and that is faster beforehand.
Then call 0333 366 0103. If it can wait — the car is at home with going nowhere — does the trick too.
While you wait for a fuel drain around Deepweir
The wait is where kindly meant help does the harm. Stick to these.
- Where your car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety ahead of the car.
- Not to roll it a couple of yards, not to check it is all right, not for a passer-by's kindness: nobody starts it.
- No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that takes that petrol back out.
- Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank remains put all the same.
- Even the radio or your windows aren't worth switching the ignition on for.
When the van arrives: your fuel drain, step by step
- Three queries. What got in, how much, and whether it's run. The answers shape the job, which is why the quote comes after them and not before.
- Your tank is cleared. The polluted mix comes from your tank.
- If it ran, your lines are holding petrol that has shifted beyond the tank — so they're cleaned.
- Cleaned, or replaced if the car has a serviceable one: your filter is sorted next.
- Clean diesel in, and your system primed.
- Our technicians fire it up only after clean diesel has gone in and bled the fuel system, then confirm that it's running smoothly.
Until it runs on fresh diesel, our technicians remain with it. The vehicle goes back to normal driving right away, and permanent damage is very uncommon if it has been noticed soon.
After the fuel drain: back on the road in Deepweir
- Once it's been started on clean fuel, there's nothing unusual to do: drive normally.
- Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or the throttle stumbling: pull over and ring us back.
- Your documents covers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it.
- Read the label on the pump next time, not the colour of its handle.
