Rednal: Petrol in a Diesel Car? Here Is What Happens
Not for a second, and not to move it: the engine remains off. Pause there. Petrol in a diesel that hasn't been run is usually a simple drain and a flush, done right where your car stands, and what happens in the coming few minutes determines that more than anything else. Below is the order from here, wherever in Rednal you happen to be.
Petrol in a diesel? What to do in minute one
First, the following — in this order.
- Keys out of the ignition. Turning your ignition on can be enough to prime the system, and priming draws petrol out of your tank towards the parts it harms. Keep the car off completely.
- Don't top it up with diesel. Adding diesel removes nothing. You are left with a bigger tank of the same mixture.
- Close to passing traffic? Then the hazards come on before anything else, and so the vehicle is simple to spot.
- Off the pump by hand. At a forecourt, ask the staff to help you push it clear of the pump. Don't start the car to shift it, however short the way.
- Which fuel, and roughly how much? Your receipt answers that, and that is where our first question starts. Don't bin it.
On the M42, under 3 miles from Rednal, the next exit is the place to leave the car; anywhere, the first safe place to stop. Don't press on to the services. Then go back to stage one.
Has it run yet? The fork in every Rednal fuel drain
Everything after this point rests on one answer.
Not run, not even once:
- The petrol is still in that tank and nowhere else.
- Where the car stands is usually where this work happens: a drain, then a flush.
- This, here, is the best spot to be in, and the whole reason stage one matters.
Motor run, even for a moment?
- Petrol has been drawn out of your tank, through the filter then into your lines.
- On a bigger run it has reached the high-pressure fuel pump as well as your injectors.
- The further it went, the bigger this job — the fuel lines, the filter, and sometimes more besides.
Diesel keeps your high-pressure pump and your injectors oiled as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. Petrol resting in a tank damages nothing. The components that shift it are wearing the moment petrol is being pumped.
Rednal, petrol in a diesel: have these ready before you call
A little preparation is the difference between a technician that finds you and a van that circles.
- The ideal start is a postcode — one beginning B45 8 — for where you have stopped.
- A road name is a help: Ashmead Drive, say, or whatever street you have stopped in. A car park works too.
- Name a car park by what it serves — the one outside M&S Foodhall, for example — and it is far quicker to find.
- Tell us what the car is — make, model — and confirm it's diesel.
- What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for Rednal, and so tell us which.
- How long the nozzle was in, or the litres from your receipt — whichever tells us how much.
- If it has run, how far and how heavily — and if it has run at all.
- Whose vehicle it is. Some hire and company contracts want the owner to approve this work, and that's quicker settled before we turn up than after.
Call 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use .
Waiting for a fuel drain around Rednal: what to do
In the wait, the damage comes from well-meant help — so these count.
- Safety before the vehicle. If it has stopped somewhere exposed, get yourself clear of the traffic and wait away from it. If it's safe where it stands, wait with it.
- Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a few yards.
- Additives remain in your boot. Injector cleaner and two-stroke oil take none of that petrol out a second time.
- 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 anyway.
- Ignition stays off. Even for the radio or the windows.
When our van arrives: your fuel drain, step by step
- Fuel, amount, whether it has run: those replies decide the job, and that is why we give a price after them rather than before.
- Draining it is how the mixture gets taken out of your tank.
- Petrol that has shifted beyond your tank sits in your lines once it ran, and the fuel lines are cleaned to clear it.
- The fuel filter is dealt with. Cleared, or changed where the vehicle has a workable one.
- Your system is primed with clean diesel.
- Starting the car. Once your system is bled with fresh diesel, our technicians start the engine and check it runs smoothly.
Our engineers stay until it's running on fresh diesel. Long-term damage is very unusual when it has been caught early, so your car can go right back to normal driving.
Back on the road around Rednal after your fuel drain
- Once it has been started on clean fuel, there is nothing unusual to do: drive normally.
- Pull over and call us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot.
- The work may come up later with a hire firm, an insurer or a fleet manager. Hold on to the paperwork.
- Next time, read the petrol pump. The label, not the colour of the handle.
