Aldermoor: Petrol in a Diesel Car? Here Is What Happens
Stop. Motor off. Keep it that way — no moment on, no shifting it at all. Cleared then purged, just where it is: that is normally all an unrun diesel with petrol in it needs. Whether it stays that simple rests on the minutes to come far more than on everything else. What follows is the sequence from this point, wherever around Aldermoor you happen to be.
Petrol in a diesel, engine off — the first minute
Work through these in sequence, before you do anything else.
- Pull the keys out. Even the ignition by itself can prime the fuel system, pulling petrol out of your tank to precisely the parts it damages, and so leave the car alone wholly.
- Topping up with diesel seems like it dilutes the trouble. It doesn't: nothing comes out, and your tank simply holds more of the same.
- Get your car easy to see first — hazards on — if there is traffic going past anywhere near you.
- Off the pump by hand. At a forecourt, get the staff to help you push the car clear of the petrol pump. Don't fire it up to move it, however short the way.
- The first question you will be asked is which fuel went in and roughly how much — and the till receipt shows both. Keep it.
If you were still on the move when you realised, stop somewhere safe instead of pushing on for the services — on the M271, under 3 miles from Aldermoor, that means the next exit. Stage one comes next.
Aldermoor fuel drain: has your motor run yet, or not?
From this stage on, everything hinges on a single answer.
Engine not run at all?
- That petrol is still inside the tank and nowhere else.
- The job is a drain and a flush, usually done where the vehicle is.
- No position is better, and it is why the first step counts so much.
If it's been started, even for a second:
- Out of that tank, through your filter, into the lines: that is how far the petrol has travelled.
- On a longer run it has got to your high-pressure pump and the fuel injectors.
- Distance is what turns it into a bigger job: flushed lines, a filter seen to, and at times further work.
Petrol does not lubricate. Diesel does, oiling your high-pressure pump and injectors as it passes through, which is why the line sits where it does. Nothing is harmed by petrol that is just sitting in a tank. Petrol being pumped is grinding down the components that move the vehicle.
Aldermoor, petrol in a diesel: have these ready before you call
Whether the technician goes round or finds you comes down to a little preparation.
- Your whereabouts: a postcode beginning SO16 5 serves best.
- The road or the car park. A road name helps — Vine Road, or wherever you have pulled up.
- What a car park serves is the easiest way to find it, and so mention the landmark — like the one at M&S Simply Food.
- That it is a diesel, plus the make and model of your car.
- What went in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Aldermoor, so say which.
- How much. Litres from the receipt, or how long the nozzle was in.
- Has it run? If so, tell us how far it got, and the way it was driven.
- Sort who owns the car ahead of when we turn up: some hire or company contracts want the owner to authorise the work, and doing it faster first.
Next, 0333 366 0103. Not pressing, your car parked at home with nowhere to be? Then works too.
Waiting for a fuel drain in Aldermoor: what to do
Help, however well meant, is what does the harm whilst you wait. So hold to these.
- Your safety comes before your car. Somewhere unsafe? Get away from the traffic and wait away from it. Safe where it stands? Stay with it.
- No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll the car a few yards.
- Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol.
- Draining it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank remains where it is regardless.
- Keep the ignition off — the windows and your radio included.
When our van gets there: your fuel drain, step by step
- Fuel, quantity, whether it has run: the answers decide the job, and that's why you get a quote after them instead of before.
- Then that tank is drained, and the contaminated fuel comes out.
- If it ran, the lines are carrying petrol that has shifted beyond the tank — so they're flushed.
- The fuel filter is seen to. Cleared, or replaced where the car has a serviceable one.
- Clean diesel goes in, and your system is primed.
- The first start on clean diesel. When priming is finished, the motor is started and our technicians check that it runs smoothly.
Only when it is running on clean diesel do our engineers go. Long-term damage is very rare if it has been spotted soon, so the vehicle can go right back to normal use.
After your fuel drain: back on the road around Aldermoor
- Nothing unusual is needed after a start with clean diesel — usual driving will do.
- Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over then ring us back.
- An insurer, a fleet manager or a hire company may ask what was carried out, so hold on to your documents.
- The handle's colour isn't the guide to go by next time — the label on the pump is.
