Shenley: Petrol in a Diesel Car? Here Is What Happens

Not for a second, and not to move it: the motor stays off. Pause there. The next few minutes determine it far more than anything else: petrol in a diesel that has not run usually comes down to clearing then cleaning, on the spot. Wherever you happen to be around Shenley, this is how things run from here.

Petrol in a diesel, motor off — the first minute

Go through the following in order, first.

  • The ignition off, keys out. Turned on, your ignition can prime the system — and priming is what draws petrol out of the tank towards the parts it damages.
  • Topping up with diesel seems like it dilutes the problem. It doesn't: nothing comes out, and that tank just holds more of the same.
  • Make your car simple to see before anything else — hazard lights on — if there's moving traffic anywhere near you.
  • However short the distance, starting it to shift it is the thing to avoid. At a forecourt, push the vehicle clear of the petrol pump by hand instead, and ask the attendants to help.
  • Keep your receipt. It shows which fuel got in and about how much, which is the first thing we will ask.

If you were still driving when you realised, stop somewhere sensible rather than pushing on for the services — on the M25, under 3 miles from Shenley, that means the next exit. Stage one follows.

Each Shenley fuel drain starts here: has the motor run?

From this point on, everything hinges on a single answer.

If the motor has not run at all:

  • That petrol is still inside that tank and nowhere else.
  • The job is a drain and a flush, normally done where your car is.
  • No position is better, and it is why the first stage matters so much.

Engine run, however briefly?

  • Petrol has been pulled out of your tank, past the fuel filter then into the lines.
  • On a bigger run it has got to the high-pressure fuel pump and your injectors.
  • Lines flushed, the fuel filter sorted, and sometimes more: the job expands as the distance does.

That line falls there because diesel lubricates the high-pressure fuel pump and the fuel injectors on its way through them — and petrol doesn't. A tank of petrol, left alone, hurts nothing. Petrol being pumped is grinding down the parts that shift it.

Shenley, petrol in a diesel: have these ready before you call

Whether the van circles or finds you comes down to a little preparation.

  • The best place to start is a postcode — one beginning WD7 9 — for where you have stopped.
  • Wherever you have pulled up, the road's name helps — whether that's London Road or somewhere else — and so does the name of a car park.
  • What a car park serves is the quickest way to find it, and so say the landmark — such as the one outside Tesco Express.
  • That it is a diesel, plus the make and model of your car.
  • Which was put in matters: AdBlue is a separate job from petrol, and Shenley has a page for it. So tell us.
  • About how much — in litres from your receipt, or by how long the nozzle was in.
  • Has it run? If so, tell us how far it went, and the way it was driven.
  • Sort who owns your car ahead of when our engineers turn up: some hire and company contracts want the owner to approve the work, and that is faster beforehand.

Then phone 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick as well.

Shenley fuel drain on its way? While you wait

The wait is where kindly meant help does the damage. Hold to these.

  • Your safety comes before the vehicle. Somewhere unsafe? Get clear of the traffic then wait away from it. Safe where it is? Wait with it.
  • Not to roll it a couple of yards, not to check it is all right, not as a passer-by's kindness: no one starts it.
  • Anything from the boot, oil meant for two-strokes or injector cleaner: no additive lifts the petrol.
  • A DIY drain misses the fuel that has already gone beyond the tank, and siphoning petrol by the road is risky too.
  • Even your radio or your windows are not worth turning the ignition on for.

Step by step: the fuel drain when our van arrives

  • Fuel, amount, whether it has run: the replies decide this job, and that's why you get a quote after them rather than before.
  • Out of the tank comes the contaminated mixture: the tank is cleared.
  • Petrol that has shifted beyond the tank travels in the fuel lines once it ran, and the lines are cleaned to clear it.
  • Then the filter: replaced where there's a usable one, cleared where there's not.
  • Your system is primed on fresh diesel.
  • Our engineers fire it up only after clean diesel has gone in and primed your system, then confirm that it is running correctly.

Until it runs on fresh diesel, our technicians stay with it. It's very uncommon for a car spotted quickly to be left with permanent damage, and normal driving resumes right away.

After your fuel drain: back on the road in Shenley

  • Drive normally. There's nothing special to do once it's been started on fresh fuel.
  • Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over and ring us back.
  • Hold on to your documents. A hire company, a fleet manager or an insurer may ask what was done.
  • Next time, trust the pump's label instead of the colour of its handle.
