Lightpill: Petrol in a Diesel Car? Here Is What Happens
Pause, and leave the motor off — not on, and not for a moment to shift it. The coming few minutes decide it more than anything else: petrol in a diesel still unrun generally comes down to draining and purging, on the spot. From here on, step by step, wherever you are in Lightpill:
Engine off: minute one with petrol in a diesel
Do the following before anything else, in this order.
- Ignition off, keys out. Switched on, the ignition can prime the system — and priming is what draws petrol out of your tank towards the parts it damages.
- No diesel on top. More fuel in takes away none of that petrol — it only leaves you with extra of the same mixture.
- Close to moving traffic? Then the hazard lights come on before everything else, and so the car is simple to see.
- Off the petrol pump by hand. At a forecourt, get the staff to help you push it clear of the pump. Don't fire it up to move it, however short the distance.
- Hold on to the till receipt: the fuel and roughly how much are written on it, and they are what our engineers ask for first.
Realised on the move? Get off at the next junction if you're on the M5, under 5 miles from Lightpill, and pull over somewhere safe — not at the services further on. Step one comes after that.
Has it run yet? The fork in every Lightpill fuel drain
From this stage on, everything hinges on a single answer.
Not run, not even once:
- That petrol is still inside your tank and nowhere else.
- The job is a simple drain and a flush, usually done where the vehicle stands.
- No place is better, and it is why the first step counts so much.
Motor run, even briefly?
- Out of your tank, past the filter, into the lines: that is how far the petrol has travelled.
- Run it farther and the petrol gets to the fuel injectors, having gone through your fuel pump first.
- Lines flushed, your filter seen to, and sometimes more: the job grows as the miles does.
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. Petrol sitting in a tank damages nothing. As soon as it's pumped, petrol begins wearing whatever moves it.
Lightpill, petrol in a diesel: have these ready before you call
Prepare a little, and the van finds you instead of circling.
- GL5 3 and the remainder of the postcode is the best way to start telling us where you are.
- Give the street — Kitesnest Lane or wherever you have pulled up — or the car park.
- Describe a car park by what it serves — the one outside Aldi, for example — and it is much easier to find.
- The car. Make, model, plus that it is a diesel.
- Which went in counts: AdBlue is a separate job from petrol, plus Lightpill has a page just for that. So tell us.
- The quantity: the receipt's litres, or else how long you held the nozzle in.
- The distance it did, and how heavily, if it ran at all.
- Hire or company car? Some contracts need the owner's go-ahead for the work, and getting it before we turn up is faster than after.
Call 0333 366 0103 once you've got that ready — or, if your car is at home, going nowhere, use .
The wait for a Lightpill fuel drain, and what to do in it
Stick to these: well-meant help causes the damage during the wait.
- Safety before the car. If it has stopped somewhere exposed, get yourself away from the traffic and wait away from it. If it's safe where it stands, stay with it.
- Nobody — however helpful — starts it, whether to see if it runs or to move the car a short way.
- Additives stay in your boot. Injector cleaner and two-stroke oil draw none of the petrol out a second time.
- Siphoning petrol into a can by the roadside is risky — and it also leaves whatever fuel has already gone beyond that tank. Don't drain the vehicle yourself.
- Not for your radio, not for the windows: the ignition remains off.
The fuel drain, step by step, once the van gets there
- Three questions. What got in, how much, and whether it's run. The answers set this job, which is why the quote comes after them but not before.
- Clearing it's how that mixture gets taken from that tank.
- The fuel lines are flushed. If it ran, the petrol has moved beyond your tank, and the lines are holding it.
- Cleaned, or swapped if the vehicle has a usable one: the filter is seen to next.
- The system is primed with fresh diesel.
- The first start on clean diesel. When priming is finished, the motor is started and our engineers make sure that it runs correctly.
Our engineers stay until it's running on new diesel. Lasting damage is very rare when it has been noticed early, so the vehicle can go straight back to normal use.
Back on the road in Lightpill after the fuel drain
- Drive normally. There is nothing unusual to do after it's been started on clean fuel.
- The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your cue to stop then call us again.
- Your paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
- Next time, go by the pump's label rather than the colour of its handle.
