What Happens Now: Petrol in a Diesel Car in Mynydd-Garn-Lwyd
Pause, and keep the motor off — not on, and not for a second to move the vehicle. Drained then purged, just where it sits: that's 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. Here's the order of things from here, anywhere you are around Mynydd-Garn-Lwyd.
Minute one: petrol in a diesel, motor off
Go through the following in order, before you do anything else.
- The ignition off, keys out. Turned on, your ignition can prime the system — and priming is what moves petrol out of the tank into the components it damages.
- No diesel on top. More fuel in takes away none of the petrol — it only leaves you with extra of the same mixture.
- Near moving traffic? Then the hazard lights go on before everything else, so your car is easy to see.
- By hand, not on your engine: that is how it comes off the pump. Ask the forecourt attendants to help you roll, whatever the distance.
- Keep the receipt: the grade and roughly how much are printed on it, and they're what we ask for first.
Still driving when you realised? Come off the M4 at the next exit if that is where you are, under 3 miles from Mynydd-Garn-Lwyd, and pull over somewhere sensible instead of pressing on to the services. Then start at step one.
Has it run yet? The fork in every Mynydd-Garn-Lwyd fuel drain
What happens next turns on one answer, and only one.
Not run, not even once:
- The petrol is still in that tank and nowhere else.
- The job is a drain and a flush, normally done where your car stands.
- Step one matters for exactly this reason: it is the best spot to be in.
If your motor has been run, even for a moment:
- The lines and the filter already hold petrol drawn out of the tank.
- Run it farther and the petrol reaches your injectors, having gone through the pump first.
- Miles is what turns it into a larger job: flushed lines, a filter seen to, and at times further work.
The line falls there because diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol doesn't. In that tank, sitting still, petrol does no harm. Once it's pumped, petrol starts grinding whatever moves it.
Mynydd-Garn-Lwyd, petrol in a diesel: have these ready before you call
Prepare a little, and the van finds you instead of circling.
- The ideal place to start is a postcode — one beginning SA6 7 — for where you have stopped.
- Give the street — Waltham Close or wherever you have stopped — or the car park.
- Or the landmark. A car park is easier to find by what it serves, such as the one at Spar.
- The make and model of the vehicle, and the fact it is a diesel.
- Which got in matters: AdBlue is a separate job from petrol, plus Mynydd-Garn-Lwyd has a page just for that. So tell us.
- How much. Litres from the receipt, or how long the nozzle was in the filler.
- If it has run, how far plus how hard — and if it has run at all.
- Whose vehicle it is. Some hire and company agreements want the owner to approve the work, and that is quicker settled before we arrive than after.
Then call 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — works as well.
Waiting for a fuel drain around Mynydd-Garn-Lwyd: what to do
Help, however well meant, is the thing that does the damage while you wait. So hold to these.
- Safety before your car. If it has stopped somewhere unsafe, get yourself away from the traffic then wait away from it. If it is safe where it sits, stay with it.
- Not to roll it a couple of yards, not to check it is all right, not as a passer-by's kindness: no one starts it.
- Additives stay in the boot. Injector cleaner and two-stroke oil draw none of the petrol out once more.
- Siphoning petrol into a can by the roadside is hazardous — and it also leaves whatever fuel has already gone beyond your tank. Don't drain the vehicle yourself.
- Even your radio or the windows aren't worth switching your ignition on for.
When our van gets there: the fuel drain, step by step
- Three queries. What was put in, how much, and if it's run. The answers set this job, which is why our quote comes after them and not before.
- Your tank is drained. The tainted blend comes out of the tank.
- Cleaning the lines comes next, since a motor that ran has petrol past the tank, inside the fuel lines themselves.
- The fuel filter is dealt with. Cleared, or replaced where the car has a workable one.
- The system is primed on clean diesel.
- Our engineers fire it up only after new diesel has gone in and bled your system, then check that it's running correctly.
Only when it is running on new diesel do our engineers go. It is very uncommon for a vehicle spotted early to be left with permanent damage, and normal use starts again right away.
Back on the road in Mynydd-Garn-Lwyd after your fuel drain
- Nothing unusual is needed after a start with fresh diesel — ordinary driving will do.
- Pull over and call us back if anything looks wrong early on — a light on your dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot.
- Keep your documents. A hire firm, a fleet manager or an insurer may ask what was carried out.
- Next time, go by the pump's label rather than the colour of its handle.
