Efail Isaf: Petrol in a Diesel Car? Here Is What Happens
Whatever you do, don't switch the motor on, even for a moment, to shift it. Pause; leave the vehicle off. The coming few minutes settle it more than anything else: petrol in a diesel that has not run normally amounts to draining then cleaning, on the spot. From now on, step by step, wherever you are around Efail Isaf:
Engine off: minute one with petrol in a diesel
Work through these in order, first.
- Keys out of the ignition. Switching the ignition on can be all it takes to prime the system, and priming pulls petrol out of the tank towards the components it damages. Keep the car off altogether.
- No diesel on top. More fuel in removes none of the petrol — it only makes you with extra of the same blend.
- Make your car simple to see before anything else — hazards on — if there is traffic going past anywhere close to you.
- The attendants will usually help you roll it clear of the pump. Let them, and roll it by hand — never on the engine, even for a few yards.
- The first question you will be asked is which fuel you put in and about how much — and the receipt shows both. Keep it.
Still driving when you realised? Come off the M4 at the next junction if that is where you are, under 3 miles from Efail Isaf, and pull over somewhere safe instead of pressing on to the services. Then begin at stage one.
Every Efail Isaf fuel drain starts here: has the engine run?
What happens next rests on one answer, and only one.
Engine not run at all?
- The petrol is still in your tank and nowhere else.
- Normally it is drained and flushed right where the vehicle stands.
- Step one matters for exactly this reason: it is the best place to be in.
If your motor has been run, even for a moment:
- The lines and your filter now carry petrol drawn out of your tank.
- Run it farther and that petrol reaches the fuel injectors, having passed through the pump first.
- Flushing your lines, the filter sorted, occasionally more: the job grows as the miles does.
Why the line falls there: diesel lubricates your high-pressure pump as well as the injectors as it flows through them, and petrol doesn't. A tank of petrol, left still, damages nothing. Move that petrol, though, and it wears the very parts that move it.
Before you call about petrol in a diesel around Efail Isaf: what our technicians need
A little preparation is the difference between a van that finds you and a technician that circles.
- The best place to start is a postcode — one beginning CF38 1 — for where you are.
- A road name is a help: Heol-y-Ffynnon, say, or whatever street you have stopped in. A car park does the trick too.
- Name a car park by what it serves — the one at Co-op Food, for instance — and it is much quicker to find.
- Tell us what your car is — make, model — and check it is diesel.
- Which got in counts: AdBlue is a separate job from petrol, plus Efail Isaf has a page for it. So tell us.
- The quantity: the receipt's litres, or else how long you had the nozzle in.
- The mileage it did, and how hard, if it ran at all.
- Hire or company car? Some contracts need the owner's go-ahead for this work, and getting it before we arrive is faster than after.
Next, 0333 366 0103. Not time-critical, the vehicle parked at home with nowhere to be? Then will do too.
Whilst you wait for a fuel drain in Efail Isaf
Help, however well meant, is the thing that does the harm while you wait. So stick to these.
- Wait with the vehicle if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.
- Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a couple of yards.
- No additives. Two-stroke oil, injector cleaner, something from your boot — none of that gets that petrol back out.
- Draining it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond that tank stays put all the same.
- Not for your radio, not for your windows: your ignition remains off.
When the van arrives: your fuel drain, step by step
- The price comes after three questions, not before them — what got in, how much, and whether it's run — since those answers decide the job.
- Next that tank is drained, and the contaminated fuel comes out.
- Cleaning your lines comes next, since a car that ran has petrol past your tank, in your lines themselves.
- The filter is sorted. Cleared, or changed where the car has a serviceable one.
- Fresh diesel goes in, then the fuel system is primed.
- The first start on new diesel. When bleeding is done, the engine is started and our technicians confirm that it runs properly.
Only once it is running on clean diesel do we go. It's very unusual for a car noticed soon to be left with long-term damage, and normal driving resumes straight away.
After your fuel drain is done: driving in Efail Isaf once more
- Started on fresh diesel, it asks nothing special of you. Simply drive normally.
- Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over then ring us back.
- The paperwork covers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
- Next time, go by the pump's label rather than the colour of its handle.
