Mold: Petrol in a Diesel Car? Here Is What Happens
Not for a second, and not to move it: your motor stays off. Stop there. Petrol in a diesel that hasn't been run is normally a drain and a flush, done where the car sits, and what happens in the next few minutes settles that far more than anything else. Here is the order of things from now, anywhere you are in Mold.
Petrol in a diesel, motor off — the first minute
Before anything else, the following — in this order.
- Ignition off, keys out. Switched on, your ignition can prime your system — and priming is what moves petrol out of your tank into the parts it harms.
- Do not top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture.
- Make the vehicle easy to see first — hazards on — if there's traffic going past anywhere close to you.
- However short the way, starting it to move it is the mistake. At a forecourt, roll the vehicle away from the pump by hand instead, then ask the attendants to lend a hand.
- Hold on to your receipt: the grade and the rough amount are printed on it, and they are what our technicians ask for first.
Noticed on the move? Get off at the next junction if you're on the M56, under 15 miles from Mold, and stop somewhere safe — not at the services further on. Stage one comes after that.
The fork in each Mold fuel drain: has it run yet?
One answer is what everything after this point depends on.
Motor never run at all?
- The petrol is still in the tank and nowhere else.
- Usually it's drained and cleaned right where the car is.
- This, here, is the best spot to be in, and the whole reason step one counts.
If it's been started, even for a second:
- Your lines and the fuel filter now carry petrol pulled from your tank.
- Run it further and that petrol gets to the fuel injectors, having gone through your fuel pump first.
- The farther it went, the larger this job — the lines, the filter, and sometimes more besides.
That line falls there because diesel lubricates the high-pressure fuel pump and the injectors on its way through them — and petrol doesn't. Petrol sitting in a tank harms nothing. Petrol being pumped is wearing the components that move the car.
What to have prepared when you call about petrol in a diesel from Mold
Prepare a little, and the van finds you rather than circling.
- CH7 1 and the rest of the postcode makes the ideal way to begin telling us where you are.
- A road name is a help: King Street, say, or whichever street you've stopped in. A car park does the trick too.
- Or the nearest landmark. A car park is easier to find by what it serves, like the one at Aldi.
- Say what the vehicle is — make, model — and confirm it is diesel.
- Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Mold page.
- How much. Litres from the receipt, or how long the nozzle was in.
- Has it run? If so, tell us how far it went, and how it was driven.
- Whose motor it is. Some hire or company contracts want the owner to authorise the work, and that's easier settled before we turn up than after.
Then phone 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick too.
Whilst you wait for a fuel drain around Mold
The wait is where well-intended help does the harm. Hold to these.
- Where the car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety ahead of the vehicle.
- Nobody — however kind — starts it, whether to see if it runs or to shift your car a short way.
- Anything from your boot, oil meant for two-strokes or injector cleaner: no additive lifts the petrol.
- No home-made clearing. Siphoning petrol into a can by the roadside is risky, and it leaves your fuel that has by now gone beyond that tank.
- Even your radio or the windows aren't worth switching your ignition on for.
Step by step: the fuel drain when the van arrives
- Fuel, volume, whether it has run: those answers decide this job, and that is why you get a price after them rather than before.
- Out of your tank comes the tainted blend: the tank is drained.
- The fuel lines are flushed. If it ran, the petrol has moved beyond the tank, and the fuel lines are holding it.
- Cleared, or swapped if the vehicle has a workable one: the fuel filter is sorted next.
- Fresh diesel goes in, then the system is primed.
- Our technicians start it only after new diesel has gone in and bled your system, then check that it's running properly.
We wait until it's running on fresh diesel. It is very uncommon for a car noticed soon to be left with long-term damage, and normal driving starts again straight away.
Once your fuel drain is done: driving around Mold once more
- Nothing special is needed after a start with clean diesel — normal driving is all.
- Pull over and call us back if anything seems wrong early on — a light on the dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot.
- The work may matter later with a hire company, an insurer or a fleet manager. Keep the documents.
- Next time, read the petrol pump. The label, not the colour of the handle.
