Madden: Petrol in a Diesel Car? Here Is What Happens
Whatever you do, don't switch the motor on, even briefly, to move it. Pause; leave the car off. Emptied then purged, right where it sits: that is normally all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes to come more than on anything else. Here's the sequence of things from now, anywhere you are around Madden.
Minute one: petrol in a diesel, motor off
Go through these in order, before you do anything else.
- Take the keys out. Even the ignition by itself can prime the system, pulling petrol out of the tank to exactly the components it harms, and so keep the vehicle alone completely.
- Don't top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mixture.
- Hazard lights on. If you are at all near moving traffic, make your car simple to see before you do anything else.
- Off the petrol pump by hand. At a forecourt, ask the attendants to help you roll it clear of the pump. Don't start the vehicle to move it, however short the distance.
- The first question we will ask is which fuel went in and about how much — and your receipt shows both. Hold on to it.
Realised on the move? Get off at the next junction if you're on the M77, over 50 miles from Madden, and stop somewhere safe — not at the services further on. Stage one comes after that.
Every Madden fuel drain starts here: has your motor run?
What comes after this turns on one answer, and only one.
Engine not run at all?
- Just the tank has petrol in it for now.
- The work is a drain and a flush, normally done where your car stands.
- Step one counts for exactly this reason: it is the best place to be in.
If your motor has been run, even briefly:
- Some petrol has left your tank already, gone through the filter, and got into your lines.
- The high-pressure pump and your injectors get it on a longer run.
- The job expands with the mileage — lines cleaned, filter seen to, occasionally more.
Petrol does not lubricate. Diesel does, oiling the high-pressure pump and injectors as it passes through, which is why the line falls where it does. Nothing is harmed by petrol that is just sitting in a tank. As soon as it is pumped, petrol starts wearing down whatever moves it.
Calling about petrol in a diesel from Madden: what to have ready
A little preparation is the difference between a technician that finds you and a technician that circles.
- The best start is a postcode — one starting BT60 3 — for where you have stopped.
- A road name helps: South Crescent, say, or whichever street you have stopped in. A car park does the trick too.
- What a car park serves is the quickest way to find it, so mention the landmark — like the one at the local shops.
- That it's a diesel, along with the make and model of the vehicle.
- Which got in matters: AdBlue is a separate job from petrol, and Madden has a page for it. So say.
- The quantity: the receipt's litres, or else how long you had the nozzle in.
- The distance it covered, and how hard, if it has run at all.
- Hire or company car? Some contracts need the owner's go-ahead for the work, and sorting it before our technicians arrive is quicker than after.
Phone 0333 366 0103 once you've got that together — or, if the car is at home, going nowhere, use .
Waiting for a fuel drain around Madden: what to do
Help, however well meant, is what does the damage whilst you wait. So hold to these.
- Wait with the car if it is safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.
- Not to roll it a few yards, not to check it is all right, not as a passer-by's favour: nobody starts it.
- No additives. Two-stroke oil, injector cleaner, something from the boot — none of it takes that petrol back out.
- No home-made emptying. Siphoning petrol into a can at the kerbside is risky, and it leaves the fuel that has already gone beyond the tank.
- Even the radio or your windows aren't worth switching your ignition on for.
The fuel drain, step by step, after our van arrives
- Three queries. What went in, how much, and if it has run. The answers shape this job, which is why our quote comes after them and not before.
- Draining it's how that blend gets taken from that tank.
- Petrol that has shifted beyond that tank travels in the fuel lines once it ran, and the lines are purged to shift it.
- Cleaned, or changed if the car has a workable one: the fuel filter is dealt with next.
- Clean diesel goes in, then the system is primed.
- The start-up. With fresh diesel in and the system primed, it is started and checked to make sure it runs smoothly.
Your car has new diesel running through it before we go. When it has been caught soon, lasting damage is very uncommon, and the vehicle goes back to normal driving straight away.
Back on the road around Madden after your fuel drain
- Started on fresh diesel, it asks nothing unusual of you. Just drive normally.
- Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over then call us back.
- The work may matter later with a hire company, an insurer or a fleet manager. Hold on to your documents.
- Next time, trust the pump's label instead of the colour of its handle.
