Harrow Weald: Petrol in a Diesel Car? Here Is What Happens
Stop. Engine off. Keep it like that — no second on, no shifting it at all. Cleared then purged, just where it is: that's normally all an unrun diesel with petrol in it takes. Whether it stays that simple rests on the minutes to come far more than on everything else. What follows is the order from here, anywhere around Harrow Weald you happen to be.
Motor off: minute one with petrol in a diesel
Before anything else, these — in this order.
- Pull the keys out. Even the ignition by itself can prime the system, pulling 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 takes out nothing. You end up with a fuller tank of the same mixture.
- Close to passing traffic? Then your hazards go on before everything else, and so the car is easy to see.
- Off the petrol pump by hand. On a forecourt, get the attendants to help you roll the vehicle clear of the petrol pump. Do not fire it up to shift it, however short the way.
- Hold on to your receipt: the fuel and the rough amount are printed on it, and they are what we ask for first.
Noticed on the move? Get off at the next junction if you're on the M1, under 3 miles from Harrow Weald, and pull over somewhere sensible — not at the services further on. Stage one starts after that.
Has it run yet? The fork in every Harrow Weald fuel drain
From this stage on, everything comes down to a single answer.
If it has never been started:
- All the petrol remains inside your tank, and only there.
- Usually it is emptied and flushed just where the vehicle stands.
- This is the best place to be in, and the reason stage one matters.
If your engine has been run, even for a moment:
- The fuel lines and the filter now carry petrol pulled out of that tank.
- On a bigger run it has got to your high-pressure pump as well as the fuel injectors.
- The job expands with the mileage — lines purged, filter sorted, occasionally more.
The reason the line falls there: diesel lubricates your high-pressure pump as well as your injectors as it flows through them, and petrol does not. Petrol resting in a tank harms nothing. Move the petrol, though, and it grinds down the very parts that move it.
Before you call about petrol in a diesel in Harrow Weald: what our engineers need
Get ready a little, and the van finds you rather than circling.
- Where you are. A postcode starting HA3 6 is the best start.
- Wherever you have pulled up, the road's name helps — whether that's Kynaston Wood or somewhere else — and so does the name of a car park.
- Car parks are found most easily by what they serve: say the one at Lidl, and it's easy.
- Say what your car is — make, model — and confirm it's diesel.
- Tell us which was put in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Harrow Weald.
- How long the nozzle was in, or the litres from the receipt — either gives us how much.
- If it's run, how far plus how heavily — and whether it's run at all.
- The owner may have to approve the work under some hire or company contracts — which is why it's faster to settle whose motor it is before our engineers arrive.
Next, 0333 366 0103. Not time-critical, the vehicle left at home with nowhere to be? Then works as well.
Waiting for a fuel drain around Harrow Weald: what to do
Help, however well meant, is the thing that does the harm while you wait. So stick to these.
- Where the vehicle has stopped decides where you wait. Exposed: away from it, away from the traffic. Safe: with it. Either way, safety before the car.
- No one starts it. Not a passer-by being kind, not to check it is all right, not to roll it a couple of yards.
- Additives remain in the boot. Injector cleaner and two-stroke oil take none of that petrol out a second time.
- Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank remains put anyway.
- Even the radio or your windows aren't worth switching your ignition on for.
When our van gets there: your fuel drain, step by step
- Our price comes after three questions, not before them — what went in, how much, and if it's run — since those answers decide the job.
- Then the tank is cleared, so the tainted fuel comes out.
- Petrol that has moved beyond the tank sits in the lines once it ran, and your lines are cleaned to shift it.
- Cleaned, or changed if your car has a workable one: the fuel filter is sorted next.
- Clean diesel goes in, and the fuel system is primed.
- Starting up. Once the fuel system is bled with fresh diesel, our technicians start it and make sure it runs properly.
Till it runs on new diesel, our technicians remain with it. The vehicle returns to normal use at once, and permanent damage is very rare when it has been noticed quickly.
After your fuel drain: back on the road around Harrow Weald
- Drive normally. There's nothing special to do after it's been started on fresh fuel.
- The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and call us again.
- The paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it.
- Next time, go by the petrol pump's label instead of the colour of its handle.
