Ty-coch: Petrol in a Diesel Car? Here Is What Happens
Pause, and leave the motor off — not on, and not for a moment to move the car. Petrol in a diesel that hasn't been run is generally a drain plus a flush, done right where the car sits, and what you do in the next few minutes determines that more than anything else. What follows is the order from here, anywhere in Ty-coch you are.
Petrol in a diesel, motor off — the first minute
Work through the following before anything else, in this sequence.
- Bleeding your fuel system pulls petrol from your tank towards the components it damages, and switching the ignition on can be enough to do that. So your keys come out, and your ignition remains off altogether.
- Topping up with diesel sounds like it dilutes the problem. It doesn't: nothing gets out, and the tank simply holds more of the same.
- Visibility comes first beside moving traffic: put the hazards on, and only then deal with anything else.
- The attendants will usually help you push it clear of the petrol pump. Let them, then move it by hand — not on the engine, even for a couple of yards.
- The first thing you will be asked is which fuel went in and roughly how much — and the receipt shows both. Keep it.
Realised on the move? Get off at the next junction if you're on the M4, under 5 miles from Ty-coch, and stop somewhere sensible — not at the services further on. Step one starts after that.
Has it run yet? The fork in each Ty-coch fuel drain
What happens after this turns on one answer, and just one.
If it has never been started:
- No place but your tank: that's where the petrol yet is.
- Normally it's drained and purged just where the vehicle stands.
- Stage one counts for precisely this reason: it is the best position to be in.
If your engine has run, even briefly:
- The lines and the filter now hold petrol drawn from that tank.
- The high-pressure pump as well as your injectors see it too on a longer run.
- Lines flushed, the fuel filter sorted, occasionally more: the job expands as the miles does.
Petrol doesn't lubricate. Diesel does, protecting the pump and injectors as it flows through, which is why the line falls where it does. A tank of petrol, left still, damages nothing. Pump the petrol, though, and it wears the very parts that move it.
What to have ready when you call about petrol in a diesel from Ty-coch
Whether the van goes round or finds you comes down to a little preparation.
- Your location: a postcode starting SA2 9 works best.
- Name the road — Harlech Crescent or wherever you have pulled up — or the car park.
- Car parks are found most easily by what they serve: say the one outside CK's, and it is simple.
- The car. Make, model, plus that it is a diesel.
- Tell us which went in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Ty-coch.
- The quantity: the receipt's litres, or else how long you held the nozzle in.
- Whether it's run. And if it has, how far and how hard.
- Hire or company car? Some contracts want the owner's authorisation for this work, and getting it before we get there is faster than afterwards.
Then phone 0333 366 0103. If it can wait — the car is at home with going nowhere — works too.
The wait for a Ty-coch fuel drain, and what to do in it
Stick to these: well-meant help does the harm during the wait.
- Wait with the car if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it.
- No one — however helpful — starts it, whether to see if it runs or to move the car a short way.
- Additives stay in your boot. Injector cleaner and two-stroke oil draw none of the petrol out a second time.
- No DIY draining. Siphoning petrol into a can by the kerbside is risky, and it leaves your fuel that has already gone beyond the tank.
- Even the radio or the windows aren't worth switching the ignition on for.
The fuel drain, step by step, once the van gets there
- The price comes after three questions, not before them — what got in, how much, and whether it has run — since those answers shape the job.
- Draining it is how that mixture gets taken out of your tank.
- Your lines are rinsed. If it ran, the petrol has moved beyond the tank, and the fuel lines are carrying it.
- Then the fuel filter: changed where there is a serviceable one, cleared where there is not.
- Priming comes after fresh diesel is in.
- The first start on new diesel. Once bleeding is complete, the motor is fired up and we check that it runs correctly.
Your car has fresh diesel running through it before our technicians go. The car goes back to normal driving straight away, and lasting damage is very rare when it has been spotted early.
After the fuel drain: back on the road around Ty-coch
- Started on clean diesel, it needs nothing unusual of you. Just drive normally.
- The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your signal to stop then call us a second time.
- The work may come up later with a hire company, an insurer or a fleet manager. Keep your paperwork.
- Next time, check the petrol pump. The label, not the colour of its handle.
