Thornwood: Petrol in a Diesel Car? Here Is What Happens
Stop. Motor off. Leave it that way — no second on, no moving it anywhere. Cleared then purged, just where it is: that's generally all an unrun diesel with petrol in it needs. Whether it stays that simple depends on the minutes ahead far more than on anything else. Here is the sequence of things from now, wherever you are around Thornwood.
Petrol in a diesel? What to do in minute one
Work through the following in order, first.
- Pull the keys out. Even your ignition by itself can prime the fuel system, pulling petrol out of the tank to exactly the components it harms, so leave it off wholly.
- No diesel on top. More fuel in takes away none of that petrol — it just makes you with extra of the same mixture.
- Close to passing traffic? Then the hazards come on before anything else, and so the car is easy to spot.
- The attendants will generally help you roll it away from the pump. Ask, and move it by hand — not under the motor, even for a few yards.
- Hold on to the receipt. It says which fuel went in plus about how much, which is the first thing we'll ask.
On the M8, under 3 miles from Thornwood, the next junction is the place to leave the car; elsewhere, the first sensible spot to stop. Do not press on to the services. Then go back to step one.
Has it run yet? The fork in each Thornwood fuel drain
From this point on, everything hinges on a single answer.
Not run, not even briefly:
- That petrol is still in the tank and nowhere else.
- Usually it's drained and flushed right where the vehicle is.
- This is the best position to be in, and the reason stage one counts.
Run at all, however briefly:
- From that tank, through your filter, into the lines: that is how far that petrol has got.
- On a bigger run it has reached the high-pressure pump as well as the injectors.
- Mileage is what makes it a bigger job: flushed lines, a filter seen to, and at times more than that.
Petrol does not lubricate. Diesel does, oiling the pump and injectors as it flows through, which is why the line falls where it does. Nothing is harmed by petrol that is just waiting in a tank. Pump that petrol, though, and it wears the very parts that move it.
Thornwood, petrol in a diesel: have these prepared before you call
Whether the technician goes round or finds you comes down to a little preparation.
- G11 6 plus the remainder of the postcode is the ideal way to begin telling us where you are.
- Give the road — Dumbarton Road or wherever you have stopped — or the car park.
- What a car park serves is the quickest way to find it, so mention the landmark — such as the one outside M&S Simply Food.
- The vehicle. Make, model, and that it is a diesel.
- Tell us which went in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Thornwood.
- Roughly how much — in litres from your receipt, or by how long the nozzle was in.
- The miles it did, and how hard, if it ran at all.
- Sort who has the vehicle before we arrive: some hire or company agreements want the owner to authorise this work, and that is quicker beforehand.
Phone 0333 366 0103 once you have got that together — or, if your car is at home, going nowhere, use .
Thornwood fuel drain on its way? Whilst you wait
Help, however well meant, is the thing that does the harm while you wait. So stick to these.
- Your safety comes before the vehicle. Somewhere dangerous? Get clear of the traffic and wait away from it. Safe where it sits? Stay with it.
- Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll the vehicle a few yards.
- No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it gets that petrol back out.
- Siphoning petrol into a can at the roadside is risky — and it also leaves whatever fuel has already gone beyond the tank. Don't drain the car yourself.
- Ignition stays off. Even for your radio or the windows.
When our van arrives: your fuel drain, step by step
- First, three questions: which fuel got in, the volume, and has it run? Those replies set this job, so the price follows them.
- Next your tank is cleared, so the tainted fuel comes out.
- Petrol that has shifted beyond the tank sits in your lines once it ran, and your lines are purged to shift it.
- Then the fuel filter: changed where there's a usable one, cleared where there is not.
- Your system is primed on fresh diesel.
- The start. With new diesel in and the system primed, it is started and checked to confirm it runs correctly.
The vehicle has new diesel running through it before our technicians leave. It's very uncommon for a car spotted quickly to be left with permanent damage, and normal driving resumes at once.
Thornwood, after the fuel drain: back on the road
- After it has been started on clean fuel, there is nothing unusual to do: drive normally.
- Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over and ring us back.
- Keep the paperwork. A hire firm, a fleet manager or an insurer may ask what was carried out.
- Next time, read the pump. The label, not the colour of the handle.
