The Next Steps, in Order: Petrol in a Diesel Car in The Green
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 clearing and rinsing, on the spot. What follows is the order from here, wherever in The Green you happen to be.
Petrol in a diesel? What to do in minute one
Work through these in sequence, before you do anything else.
- Pull the keys out. Even your ignition by itself can prime the system, pulling petrol out of your tank to precisely the components it damages, and so leave it alone wholly.
- No diesel on top. More fuel in removes none of that petrol — it only leaves you with extra of the same mixture.
- Near passing traffic? Then the hazard lights go on before anything else, so the vehicle is simple to spot.
- 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 receipt says both. Keep it.
Realised on the move? Get off at the next exit if you're on the M4, under 50 miles from The Green, and stop somewhere safe — not at the services further on. Stage one starts after that.
The Green fuel drain: has your motor run yet, or not?
Everything after this point rests on one answer.
Motor never run at all?
- The petrol is still inside that tank and nowhere else.
- Normally it's drained and cleaned right where the car is.
- This, here, is the best place to be in, and the whole reason step one counts.
Run at all, even for a second:
- Petrol has been drawn from the tank, past your filter then into the lines.
- On a longer run it has got to your high-pressure pump and the fuel injectors.
- The further it went, the bigger the job — the lines, the fuel filter, and sometimes more besides.
Diesel keeps your high-pressure pump and the fuel injectors oiled as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. Nothing is damaged by petrol that's just sitting in a tank. Move the petrol, though, and it wears the very parts doing the moving.
Before you call about petrol in a diesel around The Green: what our technicians need
A van that circles against a technician that finds you: a little preparation is the difference.
- The best place to start is a postcode — one beginning SA70 8 — for where you have stopped.
- A road name is a help: Heywood Lane, say, or whatever street you've stopped in. A car park does the trick too.
- Or the landmark. A car park is easier to find by what it serves, like the one outside Co-op Food.
- That it's a diesel, along with the make and model of the vehicle.
- Say which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for The Green.
- How long the nozzle was in, or the litres on the receipt — whichever gives us how much.
- Has it run? If so, say how far it got, and how it was driven.
- Settle who owns the vehicle before our technicians arrive: some hire or company agreements want the owner to approve this work, and that is quicker beforehand.
Phone 0333 366 0103 once you've got that together — or, if your car is at home, going nowhere, use .
Whilst you wait for a fuel drain around The Green
In the wait, the harm comes from well-intended help — which is why these count.
- Your safety comes before your car. Somewhere unsafe? Get clear of the traffic then wait away from it. Safe where it is? Stay with it.
- A helpful passer-by doesn't fire it up. Nor does anybody checking it still does the trick, or moving it a couple of yards.
- Additives remain in the boot. Injector cleaner and two-stroke oil draw none of the petrol out once more.
- A home-made drain misses the fuel already gone beyond the tank, and siphoning petrol by the road is dangerous too.
- Leave the ignition off — the windows and the radio included.
When our van gets there: the fuel drain, step by step
- The quote comes after three questions, not before them — what went in, how much, and if it has run — because the answers shape this job.
- Out of your tank comes the contaminated mix: that tank is emptied.
- If it ran, the fuel lines are holding petrol that has shifted beyond your tank — so they're purged.
- Your filter is seen to. Cleared, or changed where the car has a serviceable one.
- Priming follows once fresh diesel is in.
- Starting up. Once the fuel system is bled with fresh diesel, our technicians start the car and check it runs properly.
Only once it's running on clean diesel do our technicians leave. Lasting damage is very unusual if it has been caught soon, so the vehicle can go right back to normal driving.
The Green, after the fuel drain: back on the road
- Drive normally. There is nothing unusual to do after it's been started on clean fuel.
- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop and call us once more.
- The documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
- Next time, go by the petrol pump's label instead of the colour of its handle.
