Pen-yr-englyn: Petrol in a Diesel Car? Here Is What Happens
Whatever you do, don't switch your engine on, even for a moment, to move the car. Pause; leave it off. The coming few minutes determine it far more than anything else: petrol in a diesel that has not run normally comes down to draining then rinsing, right there. Here is the order of things from here, anywhere you are in Pen-yr-englyn.
Petrol in a diesel, motor off — the first minute
In this order, all before everything else:
- Pull the keys out. Even the ignition on its own can prime your fuel system, drawing petrol out of the tank to exactly the components it damages, so leave the car off wholly.
- Do not top it up with diesel. Adding diesel removes nothing. You are left with a bigger tank of the same mixture.
- Visibility comes first beside moving traffic: switch your hazards on, and only then think about everything else.
- By hand, never on the engine: that is how it leaves the petrol pump. Get the forecourt staff to help you push, whatever the distance.
- The first question we will ask is which fuel you put in and roughly how much — and the till receipt shows both. Keep it.
Still driving when you realised? Come off the M4 at the next exit if that is where you are, under 10 miles from Pen-yr-englyn, and stop somewhere sensible and not pushing on to the services. Then start at stage one.
Every Pen-yr-englyn fuel drain starts here: has your engine run?
One answer is what everything after this point rests on.
Engine never run at all?
- Nowhere but your tank: that's where the petrol still is.
- Draining and flushing, on the spot, is usually all of that.
- No spot is better, and it's why the first step matters so much.
Engine run, however for a moment?
- Some petrol has left your tank already, passed through your filter, and got into your lines.
- The high-pressure pump and the injectors get it on a bigger run.
- Lines flushed, your filter seen to, occasionally more: this job grows as the miles does.
The reason the line falls there: diesel protects your high-pressure pump as well as your injectors as it flows through them, and petrol does not. In the tank, left alone, petrol harms nothing. Move that petrol, though, and it wears the very parts that move it.
What to have prepared when you call about petrol in a diesel from Pen-yr-englyn
Whether the van goes round or finds you depends on a little planning.
- Where you are. A postcode starting CF42 5 is the ideal start.
- A road name is a help: Charles Street, say, or whatever street you've stopped in. A car park works too.
- Name a car park by what it serves — the one at Spar, for instance — and it's much easier to find.
- Say what the vehicle is — make, model — and check it's diesel.
- Say which went in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Pen-yr-englyn.
- How much. Litres from your receipt, or how long the nozzle was in the filler.
- Whether it has run. And if it has, how far and how hard.
- Whose vehicle it is. Some hire or company agreements want the owner to approve the work, and that is easier settled before our engineers turn up than after.
Phone 0333 366 0103 then. Email is fine as well if it can wait, with your car left at home, going nowhere.
The wait for a Pen-yr-englyn fuel drain, and what to do in it
During the wait, the damage comes from kindly meant help — so these count.
- Your safety comes before the car. Somewhere dangerous? Get clear of the traffic and wait away from it. Fine where it is? Stay with it.
- A kind passer-by doesn't start it. Nor does anyone wanting to check it still does the trick, or rolling it a few yards.
- Additives stay in your boot. Injector cleaner and two-stroke oil take none of that petrol out again.
- Siphoning petrol into a can by the roadside is risky — and it still leaves whatever fuel has already gone beyond your tank. Don't drain the vehicle yourself.
- Ignition remains off. Even for your radio or your windows.
When our van arrives: the fuel drain, step by step
- First, three questions: which fuel got in, the amount, and has it run? Those replies shape the job, and so the price follows them.
- Your tank is emptied. The tainted mixture comes out of that tank.
- The lines are cleaned. If it ran, the petrol has shifted beyond that tank, and the lines are holding it.
- Where the car has a usable filter, it's replaced; otherwise, cleared.
- Your system is primed on clean diesel.
- Starting up. When your system is bled with new diesel, our technicians start the car and make sure it runs smoothly.
The vehicle has new diesel running through it before our engineers leave. Your car returns to normal use right away, and lasting damage is very unusual when it has been spotted soon.
After the fuel drain: back on the road in Pen-yr-englyn
- Once it has been started on fresh fuel, there is nothing special to do: drive normally.
- Pull over and call us back if anything looks wrong early on — a light on your dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot.
- Hold on to the documents. A hire firm, a fleet manager or an insurer may ask what was carried out.
- Next time, check the petrol pump. The label, not the colour of its handle.
