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

Whatever you do, don't switch the motor on, even for a moment, to shift the vehicle. Stop; leave the vehicle off. The next few minutes decide it far more than anything else: petrol in a diesel that has not run normally comes down to clearing and rinsing, right there. Here is the sequence of things from now, anywhere you are in Rhiwderin.

Petrol in a diesel? What to do in minute one

Work through these in sequence, first.

  • The keys out of the ignition. Switching your ignition on can be all it takes to prime the fuel system, while priming draws petrol out of the tank toward the parts it damages. Leave the car off altogether.
  • Do not top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mix.
  • Close to passing traffic? Then the hazard lights come on before everything else, and so the car is easy to see.
  • The staff will usually help you roll it clear of the pump. Ask, and roll it by hand — never on the motor, even for a few yards.
  • Keep the receipt. It shows which fuel got in plus roughly how much, which is the first thing we will ask.

On the M4, under 3 miles from Rhiwderin, the next exit is the spot to come off; anywhere, the first safe location to stop. Do not push on to the services. Then go back to step one.

Each Rhiwderin fuel drain starts here: has the engine run?

What happens next rests on one answer, and only one.

If your motor hasn't run at all:

  • Only the tank has petrol in it so far.
  • The work is a drain and a flush, usually done where your car stands.
  • This is the best position to be in, and the reason step one matters.

Motor run, even for a moment?

  • From that tank, past the fuel filter, into the lines: that's how far that petrol has got.
  • On a longer run it has got to the high-pressure fuel pump as well as the injectors.
  • The further it went, the bigger the job — your lines, the fuel filter, and sometimes more besides.

Diesel keeps the high-pressure fuel pump and your injectors oiled as it runs through them. Petrol offers them nothing, and that's why the line is drawn there. Petrol sitting in a tank damages nothing. The parts that move it are wearing the moment petrol is being pumped.

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

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

  • Where you have stopped. A postcode beginning NP10 8 is the best start.
  • Give the street — Tredegar Street or wherever you have stopped — or the car park.
  • Name a car park by what it serves — the one outside What!, for example — and it's much quicker to find.
  • Make and model of your vehicle, and the fact it's a diesel.
  • Say which was put in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Rhiwderin.
  • How much. Litres from your receipt, or how long the nozzle was in the filler.
  • The distance it covered, and how heavily, if it has run at all.
  • Hire or company car? Some contracts want the owner's go-ahead for the work, and sorting it before our engineers get there is quicker than after.

Phone 0333 366 0103 then. Email is fine too if it can wait, with the vehicle left at home, going nowhere.

Rhiwderin fuel drain on its way? Whilst you wait

Help, however well meant, is what does the damage while you wait. So stick to these.

  • Safety before the vehicle. If it has stopped somewhere unsafe, get yourself clear of the traffic and wait away from it. If it is safe where it is, wait with it.
  • A helpful passer-by does not fire it up. Nor does anyone checking it still does the trick, or rolling it a couple of yards.
  • No additives. Two-stroke oil, injector cleaner, anything from your boot — none of it gets that petrol back out.
  • A DIY drain leaves the fuel that has already gone beyond the tank, and siphoning petrol by the road is risky too.
  • Not for the radio, not for the windows: your ignition stays off.

The fuel drain, step by step, once the van arrives

  • Our price comes after three queries, not before them — what was put in, how much, and whether it has run — because the answers set this job.
  • Then the tank is emptied, and the contaminated fuel comes out.
  • If it ran, the lines are carrying petrol that has shifted beyond your tank — so they're rinsed.
  • Then the filter: replaced where there is a usable one, cleared where there is not.
  • Clean diesel in, and the system primed.
  • Starting up. Once the system is primed with clean diesel, our engineers start it and confirm it runs correctly.

The vehicle has clean diesel running through it before we head off. Lasting damage is very rare when it has been spotted early, so the car can go right back to normal driving.

Once your fuel drain is done: driving around Rhiwderin again

  • Started on clean diesel, it asks nothing unusual of you. Simply drive normally.
  • Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over and ring us back.
  • The paperwork answers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
  • Next time, check the pump. The label, not the colour of the handle.
