What Happens Now: Petrol in a Diesel Car in Rockhead
Whatever you do, don't switch your motor on, even for a moment, to move the vehicle. Pause; leave it off. Hasn't been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever the car has stopped — and nothing decides that as much as the next few minutes do. Here is the order of things from here, wherever you are around Rockhead.
Petrol in a diesel, engine off — the first minute
Work through these first, in this order.
- Ignition off, keys out. Turned on, your ignition can prime the system — and priming is what draws petrol out of the tank into the parts it damages.
- Do not top it up with diesel. Adding diesel removes nothing. You end up with a fuller tank of the same mix.
- Near moving traffic? Then your hazards come on before everything else, and so the vehicle is simple to see.
- Off the pump by hand. At a forecourt, ask the staff to help you push it clear of the petrol pump. Don't crank it to move it, however short the distance.
- Which fuel, and roughly how much? The receipt answers both, and that's where our first question starts. Don't bin it.
Realised on the move? Get off at the next exit if you are on the M5, over 50 miles from Rockhead, and stop somewhere sensible — not at the services farther on. Stage one starts after that.
The fork in each Rockhead fuel drain: has it run yet?
What happens after this turns on one answer, and only one.
If the engine hasn't run at all:
- That petrol is still inside the tank and nowhere else.
- The work is a simple drain and a flush, normally done where the vehicle stands.
- Being here is the best case — which is the whole point of step one.
Run at all, even for a second:
- The lines and the filter already carry petrol drawn out of your tank.
- A longer run carries it all the way to your high-pressure pump and the injectors.
- Distance is what turns it into a bigger job: flushed lines, a filter seen to, and at times more than that.
The reason the line falls there: diesel lubricates the high-pressure pump and your injectors as it passes through them, and petrol doesn't. Petrol sitting in a tank harms nothing. Petrol being pumped is grinding down the components that move it.
Before you call about petrol in a diesel around Rockhead: what our technicians need
A technician that circles against a van that finds you: a little planning is what separates them.
- Your location: a postcode starting PL33 9 works best.
- The road or the car park. A road name helps — Rendle Street, or wherever you have pulled up.
- Car parks are located most easily by what they serve: tell us the one outside Spar, and it's easy.
- The car. Make, model, and that it's a diesel.
- Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has a separate Rockhead page.
- The amount: your receipt's litres, or otherwise how long you held the nozzle in.
- If it's run, how far and how heavily — and whether it's run at all.
- Whose vehicle it is. Some hire or company contracts want the owner to approve the work, and that's easier settled before our engineers arrive than after.
Next, 0333 366 0103. Not urgent, the car parked at home with nowhere to be? Then works as well.
Whilst you wait for a fuel drain around Rockhead
The wait is where kindly meant help does the damage. Stick 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's safe where it is, stay with it.
- A helpful passer-by does not crank it. Nor does anyone wanting to check it still works, or rolling it a couple of yards.
- Additives stay in the boot. Injector cleaner and two-stroke oil draw none of the petrol out a second time.
- Siphoning petrol into a can at the kerbside is risky — and it still leaves whatever fuel has already gone beyond your tank. Don't drain it yourself.
- Keep your ignition off — the windows and your radio included.
Step by step: your fuel drain when our van gets there
- Fuel, quantity, whether it's run: those answers decide the job, and that is why we give a price after them rather than before.
- Out of the tank comes the polluted mixture: your tank is cleared.
- Petrol that has shifted beyond your tank travels in the lines if it ran, and the fuel lines are purged to clear it.
- Then the filter: swapped where there's a workable one, cleared where there's not.
- Priming comes once fresh diesel is in.
- Our engineers fire it up only after fresh diesel has gone in and primed your system, then confirm that it's running correctly.
The car has clean diesel running through it before our technicians go. Lasting damage is very uncommon when it has been spotted soon, so the vehicle can go right back to normal use.
Back on the road in Rockhead after the fuel drain
- Started on clean diesel, it needs nothing unusual of you. Simply drive normally.
- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop then call us again.
- An insurer, a fleet manager or a hire firm may ask what was done, so hold on to your paperwork.
- Next time, check the pump. The label, not the colour of the handle.
