Y Parc: Petrol in a Diesel Car? Here Is What Happens
Pause, and leave your engine off — not on, and not for a second to shift the vehicle. Cleared and rinsed, right where it sits: that's usually all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes to come far more than on everything else. Anywhere you happen to be in Y Parc, this is the order things run from here.
Engine off: minute one with petrol in a diesel
Work through the following in sequence, first.
- Take your keys out. Even your ignition on its own can prime the system, drawing petrol out of your tank to precisely the components it damages, so leave the car off completely.
- Do not top it up with diesel. Adding diesel takes out nothing. You end up with a fuller tank of the same mix.
- Hazards on. If you are at all near moving traffic, make the vehicle easy to see before you do anything else.
- Off the pump by hand. At a forecourt, get the staff to help you push the car away from the pump. Do not crank it to move it, however short the way.
- Hold on to your receipt. It shows which fuel was put in plus roughly how much, which is the first thing we will ask.
Still driving when you noticed? Come off the M4 at the next exit if that's where you are, under 5 miles from Y Parc, and stop somewhere sensible instead of pressing on to the services. Then start at stage one.
The fork in every Y Parc fuel drain: has it run yet?
One answer is what everything after this stage depends on.
Not run, not even briefly:
- That petrol is still in your tank and nowhere else.
- Normally it is emptied and rinsed just where your car is.
- No spot is better, and it is why the first step counts so much.
If it has been started, even for a second:
- The lines and the filter now hold petrol pulled out of the tank.
- On a longer run it has reached the high-pressure fuel pump as well as the fuel injectors.
- The job grows with the mileage — lines rinsed, filter sorted, occasionally more.
Diesel keeps the high-pressure fuel pump and the fuel injectors protected as it goes through them. Petrol gives them nothing, and that's why the line is drawn there. Nothing is damaged by petrol that is only sitting in a tank. Move that petrol, though, and it grinds down the very parts that move it.
Before you call about petrol in a diesel in Y Parc: what our technicians need
Whether the van goes round or finds you comes down to a little preparation.
- Where you are. A postcode beginning CF34 9 is the ideal start.
- The road or the car park. A road name is a help — Heol Pentre, or wherever you have pulled up.
- Describe a car park by what it serves — the one at Aldi, for example — and it's much quicker to find.
- The vehicle. Make, model, and that it's a diesel.
- What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for Y Parc, so tell us which.
- About how much — in litres from your receipt, or by how long the nozzle was in.
- Whether it has run. Then if it has, how far plus how heavily.
- Whose vehicle it is. Some hire or company agreements want the owner to authorise this work, and that is quicker settled before we turn up than after.
Call 0333 366 0103 once you've got that together — or, if your car is at home, going nowhere, use .
Whilst you wait for a fuel drain around Y Parc
Help, however well meant, is the thing that does the harm whilst you wait. So hold to these.
- Your safety comes before the car. Somewhere unsafe? Get clear of the traffic and wait away from it. Safe where it stands? Wait with it.
- A helpful passer-by doesn't fire it up. Nor does anybody checking it still does the trick, or rolling it a couple of yards.
- No additives. Two-stroke oil, injector cleaner, something from your boot — none of it gets the petrol back out.
- Siphoning petrol into a can at the kerbside is dangerous — and it also leaves whatever fuel has already gone beyond your tank. Do not drain the car yourself.
- Even the radio or your windows are not worth switching your ignition on for.
The fuel drain, step by step, once our van gets there
- Fuel, amount, whether it's run: the answers decide the job, and that is why we give a price after them rather than before.
- Next the tank is drained, so the tainted fuel comes out.
- Petrol that has shifted beyond your tank sits in the fuel lines once it ran, and the lines are cleaned to clear it.
- Cleaned, or replaced if the vehicle has a workable one: the fuel filter is seen to next.
- Clean diesel in, and your system primed.
- The first start on fresh diesel. When priming is done, the engine is fired up and we check that it runs correctly.
Your car has clean diesel running through it before our engineers head off. It's very uncommon for a car noticed soon to be left with long-term damage, and normal driving starts again right away.
After your fuel drain: back on the road around Y Parc
- Started on new diesel, it asks nothing unusual of you. Simply drive normally.
- The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and ring us once more.
- The work may come up later with a hire company, an insurer or a fleet manager. Keep your documents.
- Read the label on the pump next time, not the colour of its handle.
