Tarn: Petrol in a Diesel Car? Here Is What Happens
Not for a second, and not for moving it: the motor remains off. Pause there. The next few minutes decide it far more than anything else: petrol in a diesel that has not run generally amounts to emptying and rinsing, on the spot. Here is the sequence of things from now, anywhere you're around Tarn.
Petrol in a diesel? What to do in minute one
First, the following — in this order.
- Keys out of your ignition. Turning your ignition on can be enough to prime the system, while priming draws petrol out of your tank towards the parts it damages. Keep the car off altogether.
- No diesel on top. More fuel in removes none of that petrol — it just makes you with extra of the same blend.
- Close to moving traffic? Then your hazards come on before anything else, and so the car is simple to spot.
- By hand, not on the engine: that's how it leaves the pump. Ask the forecourt attendants to help you push, whatever the distance.
- Keep your receipt: the fuel and roughly how much are written on it, and they are what our engineers ask about first.
Still on the move when you realised? Come off the M606 at the next junction if that's where you are, under 10 miles from Tarn, and pull over somewhere sensible instead of pushing on to the services. Then begin at step one.
Tarn fuel drain: has the engine run yet, or not?
Everything after this point rests on one answer.
Not run, not even briefly:
- The petrol sits inside that tank, and only there.
- Draining and flushing, on the spot, is usually the whole job.
- No position is better, and it is why the first stage matters so much.
If the motor has run, even briefly:
- Out of your tank, through the fuel filter, into the fuel lines: that's how far that petrol has travelled.
- On a bigger run it has got to the high-pressure pump as well as your injectors.
- Distance is what makes it a larger job: flushed lines, a filter seen to, and at times more than that.
The reason the line falls there: diesel lubricates the high-pressure pump and the fuel injectors as it flows through them, and petrol does not. In that tank, sitting still, petrol harms nothing. Move the petrol, though, and it wears the very parts that move it.
Before you call about petrol in a diesel around Tarn: what our engineers need
Get ready a little, and the technician finds you instead of circling.
- Where you have stopped. A postcode starting BD17 7 is the ideal start.
- Give the street — Roundwood Road or wherever you have stopped — or the car park.
- What a car park serves is the quickest way to find it, and so mention the landmark — like the one at Aldi.
- The make and model of your vehicle, and the fact it's a diesel.
- Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has a separate Tarn page.
- The quantity: the receipt's litres, or otherwise how long you held the nozzle in.
- If it's run, how far plus how hard — and if it has run at all.
- The owner may have to authorise the work under some hire and company agreements — so it's quicker to settle whose car it is before our technicians arrive.
Ring 0333 366 0103 then. Email works as well if it can wait, with the car left at home, going nowhere.
Whilst you wait for a fuel drain around Tarn
Hold to these: well-intended help causes the damage during the wait.
- Wait with the vehicle 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 starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a couple of yards.
- Additives remain in the boot. Injector cleaner and two-stroke oil take none of the petrol out a second time.
- Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond the tank remains put anyway.
- Even the radio or your windows aren't worth switching the ignition on for.
Step by step: the fuel drain when our van arrives
- First, three questions: which fuel got in, the quantity, and has it run? Those replies shape this job, and so the quote follows them.
- Your tank is cleared. The contaminated mixture comes from the tank.
- If it ran, your lines are holding petrol that has shifted beyond the tank — so they're flushed.
- Where the vehicle has a serviceable filter, it is replaced; otherwise, cleared.
- Your system is primed on fresh diesel.
- Starting it. When the system is primed with clean diesel, our technicians start the car and make sure it runs smoothly.
Till it runs on new diesel, our technicians stay with it. Your car goes back to normal driving at once, and lasting damage is very rare if it has been noticed soon.
Tarn, after your fuel drain: back on the road
- Started on fresh diesel, it needs nothing special of you. Just drive normally.
- Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle means pull over then call us back.
- An insurer, a fleet manager or a hire company may ask what was done, so hold on to your documents.
- Read the label on the petrol pump next time, not the colour of the handle.
