Petrol in a Diesel Car in Cwmbran: What Happens Now
Whatever you do, never switch your motor on, even briefly, to shift the car. Stop; leave the vehicle off. Petrol in a diesel that hasn't been run is normally a simple drain plus a flush, done right where your car stands, and what you do in the coming few minutes settles that far more than anything else. What follows is the order from here, anywhere in Cwmbran you happen to be.
Petrol in a diesel, engine off — the first minute
Do the following before anything else, in this sequence.
- Take the keys out. Even the ignition by itself can prime the system, pulling petrol out of your tank to exactly the parts it damages, and so leave it off entirely.
- Topping up with diesel seems like it thins the issue. It doesn't: nothing gets out, and that tank just holds more of the same.
- Make your car simple to see before anything else — hazards on — if there is moving traffic anywhere near you.
- Off the pump by hand. At a forecourt, get the staff to help you push it away from the petrol pump. Do not fire it up to move it, however short the distance.
- The first thing we will ask is which fuel you put in and about how much — and the till receipt shows both. Hold on to it.
On the M4, under 5 miles from Cwmbran, the next junction is the location to come off; elsewhere, the first safe place to stop. Don't press on to the services. Then go back to step one.
Has it run yet? The fork in every Cwmbran fuel drain
One answer is what everything after this stage depends on.
Not run, not even once:
- The petrol sits inside the tank, and just there.
- A drain and flush, on the spot, is usually the whole job.
- Stage one matters for precisely this reason: it is the best spot to be in.
Motor run, however for a moment?
- Petrol has been drawn out of your tank, past the fuel filter then into the lines.
- A bigger run carries it right through to your high-pressure pump and the injectors.
- Distance is what makes it a larger job: flushed lines, a filter seen to, and at times further work.
Diesel keeps the high-pressure pump and the injectors lubricated as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. Nothing is damaged by petrol that is only resting in a tank. Pump the petrol, though, and it grinds down the very parts that move it.
Cwmbran, petrol in a diesel: have these prepared before you call
Get ready a little, and the van finds you instead of circling.
- NP44 1 plus the remainder of the postcode is the ideal way to start telling us where you are.
- The street or the car park. A road name helps — North Walk, or wherever you have stopped.
- Or the landmark. A car park is quicker to find by what it serves, such as the one at DW Food To Go.
- Make and model of the vehicle, and the fact it's a diesel.
- Which went in counts: AdBlue is a separate job from petrol, plus Cwmbran has a page for it. So say.
- About how much — in litres from the receipt, or by how long the nozzle was in.
- Whether it's run. Then if it has, how far plus how heavily.
- Hire or company car? Some contracts need the owner's go-ahead for the work, and getting it before our technicians get there is faster than after.
Ring 0333 366 0103 once you have got that ready — or, if your car is at home, going nowhere, use .
While you wait for a fuel drain in Cwmbran
Hold to these: kindly meant help does the damage during the wait.
- Where the vehicle has stopped settles where you wait. Somewhere exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety ahead of your car.
- Not to roll it a few yards, not to check it is all right, not for a passer-by's kindness: no one starts it.
- Anything from the boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol.
- Siphoning petrol into a can at the kerbside is dangerous — and it still leaves whatever fuel has already gone beyond your tank. Don't try a home-made drain.
- Leave the ignition off — the windows and your radio too.
Step by step: your fuel drain when our van gets there
- Three questions. What was put in, how much, and if it's run. Those answers decide this job, which is why the quote comes after them and not before.
- Out of your tank comes the contaminated blend: that tank is cleared.
- Flushing the fuel lines comes next, because a car that ran has petrol past the tank, inside your lines themselves.
- Cleared, or changed if the vehicle has a usable one: the filter is sorted next.
- Your system is primed with clean diesel.
- Starting up. When the fuel system is primed with fresh diesel, our technicians start it and check it runs smoothly.
Our technicians remain until it is running on fresh diesel. It's very unusual for a vehicle caught soon to be left with permanent damage, and normal driving starts again right away.
Back on the road in Cwmbran after the fuel drain
- After it's been started on clean fuel, there's nothing unusual to do: drive normally.
- Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle stumbling: pull over then call us back.
- Keep the paperwork. A hire company, a fleet manager or an insurer may ask what was carried out.
- Next time, trust the pump's label instead of the colour of its handle.
