Ford: Petrol in a Diesel Car? Here Is What Happens
Stop. Motor off. Leave it like that — no moment on, no shifting it at all. The next few minutes determine it far more than anything else: petrol in a diesel that has not run generally comes down to draining and cleaning, right there. From now on, step by step, for anywhere around Ford:
Engine off: minute one with petrol in a diesel
Work through these in order, before you do anything else.
- Ignition off, keys out. Turned on, your ignition can prime the system — and priming is what moves petrol out of your tank towards the parts it harms.
- Topping up with diesel seems like it thins the trouble. It doesn't: nothing comes out, and your tank simply holds more of the same.
- Make your car easy to see first — hazards on — if there's traffic going past anywhere close to you.
- The staff will generally help you roll it away from the pump. Ask, and move it by hand — not under the engine, even for a couple of yards.
- Keep your receipt. It shows which fuel got in plus about how much, which is the first thing we'll ask.
Noticed on the move? Get off at the next junction if you are on the M5, under 50 miles from Ford, and pull over somewhere sensible — not at the services farther on. Stage one comes after that.
Every Ford fuel drain starts here: has your engine run?
What comes after this rests on one answer, and only one.
Not run, not even briefly:
- Nowhere but your tank: that's where the petrol still is.
- A drain and flush, on the spot, is normally all of it.
- No position is better, and it's why the first step matters so much.
Run at all, even for a second:
- Some petrol has left that tank by now, gone through the filter, and got into the fuel lines.
- Run it further and that petrol reaches the fuel injectors, having gone through your pump first.
- The further it went, the bigger the job — the lines, the filter, and now and then more besides.
The reason the line falls there: diesel lubricates the high-pressure fuel pump and the injectors as it flows through them, and petrol does not. In the tank, left alone, petrol harms nothing. Pump the petrol, though, and it wears the very parts doing the moving.
Calling about petrol in a diesel from Ford: what to have ready
A van that circles versus a technician that finds you: a little planning is what separates them.
- Your whereabouts: a postcode beginning PL2 1 serves best.
- Wherever you have parked, the road's name helps — whether that's Auckland Road or somewhere else — and so does the name of a car park.
- Or the landmark. A car park is quicker to find by what it serves, such as the one at Co-op Food.
- Make and model of the vehicle, and the fact it is a diesel.
- Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Ford page.
- Roughly how much — in litres from the receipt, or by how long the nozzle stayed in.
- If it has run, how far and how hard — and whether it's run at all.
- Hire or company car? Some agreements need the owner's authorisation for this work, and getting it before our engineers arrive is faster than afterwards.
Phone 0333 366 0103 next. Email is fine as well if it can wait, with your car left at home, going nowhere.
Whilst you wait for a fuel drain in Ford
During the wait, the harm comes from well-intended help — which is why these matter.
- Wait with your car 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 — however kind — starts it, whether to see if it runs or to move the car a short way.
- Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol.
- Siphoning petrol into a can at the roadside is hazardous — and it still leaves whatever fuel has already gone beyond that tank. Don't drain the car yourself.
- The ignition stays off. Even for your radio or the windows.
When the van arrives: the fuel drain, step by step
- Fuel, volume, whether it's run: the replies set this job, and that's why you get a quote after them rather than before.
- Out of your tank comes the tainted mix: the tank is drained.
- If it ran, the lines are carrying petrol that has moved beyond the tank — so they are flushed.
- Cleaned, or changed if the car has a usable one: the fuel filter is seen to next.
- Fresh diesel in, and your system primed.
- Our engineers fire it up only after clean diesel has gone in and bled your system, then check that it is running properly.
Our technicians stay until it is running on fresh diesel. If it has been caught early, long-term damage is very unusual, and the vehicle goes back to normal use right away.
Back on the road around Ford after the fuel drain
- Once it has been started on clean fuel, there is nothing special to do: drive normally.
- The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and call us a second time.
- The paperwork answers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it.
- Check the label on the pump next time, not the colour of its handle.
