Prisk: Petrol in a Diesel Car? Here Is What Happens
Pause, then keep the engine off — not on, and not for a second to move the vehicle. The next few minutes determine it far more than anything else: petrol in a diesel that has not run generally amounts to clearing then flushing, on the spot. Here's the order of things from now, wherever you're in Prisk.
Petrol in a diesel, engine off — the first minute
First, the following — following this order.
- Ignition off, keys out. Switched on, your ignition can prime the system — and priming is what draws petrol out of your tank towards the parts it harms.
- Topping up with diesel seems like it dilutes the issue. It doesn't: nothing comes out, and that tank just carries more of the same.
- Hazards on. If you are at all close to moving traffic, make the car easy to see before you do anything else.
- By hand, not on the motor: that's how it comes off the pump. Ask the forecourt attendants to help you roll, however short the miles.
- Hold on to your receipt: the grade and roughly how much are printed on it, and they're what we ask for first.
Still on the move when you realised? Come off the M4 at the next exit if that is where you are, under 3 miles from Prisk, and pull over somewhere safe instead of pushing on to the services. Then start at stage one.
Prisk fuel drain: has the engine run yet, or not?
What comes next turns on one answer, and only one.
If it has never been started:
- No place but the tank: that's where the petrol still is.
- Normally it is drained and flushed just where the vehicle stands.
- This, here, is the best spot to be in, and the reason stage one matters.
If it has been started, even for a second:
- Petrol has been drawn out of the tank, through the fuel filter then into your lines.
- A bigger run takes it right through to your high-pressure pump and the injectors.
- Lines flushed, the filter seen to, occasionally 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 sits where it does. A tank of petrol, left alone, hurts nothing. Once it is pumped, petrol starts wearing down whatever moves it.
Prisk, petrol in a diesel: have these ready before you call
A little preparation is the difference between a van that finds you and a technician that goes round.
- Your location: a postcode starting CF71 7 works best.
- The road or the car park. A road name helps — Watery Lane, or wherever you have pulled up.
- Describe a car park by what it serves — the one outside Filco, for example — and it is much quicker to find.
- The make and model of your vehicle, and the fact it's a diesel.
- Say which was put in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Prisk.
- How long the nozzle was in, or the litres on the receipt — whichever gives us how much.
- Has it run? If so, tell us how far it went, and the way it was driven.
- Sort who owns the vehicle ahead of when our technicians turn up: some hire and company agreements want the owner to authorise this work, and doing it quicker first.
Then phone 0333 366 0103. If it can wait — your car is at home and going nowhere — works as well.
The wait for a Prisk fuel drain, and what to do in it
Help, however well meant, is what does the damage while you wait. So stick to these.
- Stay with your car if it's safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it.
- A kind passer-by doesn't fire it up. Nor does anyone wanting to check it still does the trick, or moving it a few yards.
- Additives stay in your boot. Injector cleaner and two-stroke oil draw none of that petrol out once more.
- A DIY drain misses the fuel that has already gone beyond your tank, and siphoning petrol by the road is risky too.
- Ignition remains off. Even for your radio or the windows.
The fuel drain, step by step, once our van arrives
- Three queries. What got in, how much, and if it's run. Those replies decide this job, which is why our price comes after them but not before.
- Out of your tank comes the tainted mix: that tank is cleared.
- Purging your lines follows, since a motor that ran has petrol past that tank, inside the lines themselves.
- Then the fuel filter: replaced where there's a workable one, cleared where there is not.
- The system is primed on fresh diesel.
- The start. With new diesel in and the system bled, it's fired up and tested to make sure it runs smoothly.
Only once it's running on clean diesel do our technicians leave. Lasting damage is very unusual when it has been caught quickly, so your car can go straight back to normal use.
After the fuel drain: back on the road in Prisk
- Drive normally. There is nothing unusual to do once it has been started on clean fuel.
- Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over then call us back.
- An insurer, a fleet manager or a hire company may ask what was done, and so keep the paperwork.
- Check the label on the pump next time, not the colour of the handle.
