Old Dock: Petrol in a Diesel Car? Here Is What Happens
Pause, then keep your motor off — not on, and not for a second to move the vehicle. Drained and rinsed, right where it is: that is usually all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes to come more than on anything else. From here on, step by step, for anywhere around Old Dock:
Petrol in a diesel? What to do in minute one
Before anything else, these — following this sequence.
- Take your keys out. Even the ignition on its own can prime the system, drawing petrol out of the tank to precisely the parts it damages, so leave the vehicle alone entirely.
- Topping up with diesel seems like it thins the problem. It does not: nothing gets out, and the tank just carries more of the same.
- Hazard lights on. If you're anywhere near moving traffic, make the car easy to see before you do anything else.
- However short the distance, starting it to move it is the thing to avoid. At a forecourt, roll it clear of the petrol pump by hand instead, and ask the staff to lend a hand.
- Keep the till receipt: the fuel and roughly how much are printed on it, and they are what our engineers ask for first.
On the M5, under 5 miles from Old Dock, the next exit is the location to leave the car; elsewhere, the first safe place to stop. Do not push on to the services. Then go back to stage one.
Has it run yet? The fork in each Old Dock fuel drain
One answer is what everything after this stage depends on.
Not run, not even briefly:
- The petrol is still inside your tank and nowhere else.
- Normally it is drained and purged right where the vehicle is.
- No spot is better, and it's why the first step counts so much.
If the engine has been run, even for a moment:
- The lines and the fuel filter now hold petrol pulled from your tank.
- On a longer run it has reached your high-pressure pump and the fuel injectors.
- The further it went, the bigger the job — the fuel lines, the filter, and sometimes more besides.
The line falls there because diesel lubricates the high-pressure fuel pump and your injectors on its way through them — and petrol doesn't. A tank of petrol, left alone, damages nothing. Once it's pumped, petrol begins grinding whatever moves it.
Before you call about petrol in a diesel in Old Dock: what our engineers need
Get ready a little, and the van finds you rather than circling.
- DY1 1 and the remainder of the postcode makes the best way to start telling us where you are.
- Give the street — Queen's Cross or wherever you have stopped — or the car park.
- Or the landmark. A car park is easier to find by what it serves, like the one at Asda.
- That it is a diesel, plus the make and model of the car.
- Which went in matters: AdBlue is a separate job from petrol, and Old Dock has a page for it. So say.
- How long the nozzle was in, or the litres from your receipt — whichever tells us how much.
- The distance it covered, and how heavily, if it ran at all.
- Whose motor it is. Some hire or company contracts want the owner to approve this work, and that is quicker settled before we turn up than after.
Then call 0333 366 0103. If it can wait — the car is at home with going nowhere — works too.
Old Dock fuel drain on its way? While you wait
The wait is where well-meant help does the damage. Stick to these.
- Wait with the vehicle if it is safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.
- A helpful passer-by does not crank it. Nor does anyone wanting to check it still works, or moving it a couple of yards.
- No additives. Two-stroke oil, injector cleaner, something from the boot — none of it takes the petrol back out.
- A DIY drain misses the fuel already gone beyond that tank, and siphoning petrol by the road is dangerous too.
- The ignition stays off. Even for the radio or your windows.
When our van arrives: your fuel drain, step by step
- Three queries. What was put in, how much, and if it's run. Those replies shape the job, which is why the price comes after them but not before.
- That tank is emptied. The contaminated mixture comes from the tank.
- The lines are flushed. If it ran, the petrol has moved beyond your tank, and the lines are carrying it.
- Cleaned, or replaced if the vehicle has a serviceable one: the fuel filter is sorted next.
- Clean diesel in, and your system primed.
- Our engineers fire it up only after clean diesel has gone in and primed your system, then check that it's running smoothly.
The car has new diesel running through it before we go. It's very unusual for a car spotted early to be left with lasting damage, and normal driving resumes straight away.
Old Dock, after the fuel drain: back on the road
- Once it's been started on clean fuel, there is nothing unusual to do: drive normally.
- Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle stumbling: pull over then call us back.
- The work may come up later with a hire company, an insurer or a fleet manager. Hold on to your documents.
- Read the label on the petrol pump next time, not the colour of its handle.
