Havering-atte-Bower: Petrol in a Diesel Car? Here Is What Happens
Not for a moment, and not to move it: the engine stays off. Pause there. The next few minutes settle it more than anything else: petrol in a diesel still unrun normally amounts to clearing then cleaning, on the spot. Below is the sequence from this point, anywhere in Havering-atte-Bower you happen to be.
Minute one: petrol in a diesel, engine off
Do the following first, in this order.
- Take the keys out. Even the ignition on its own can prime your fuel system, pulling petrol out of your tank to exactly the components it harms, so leave the car off completely.
- Do not top it up with diesel. Adding diesel takes out nothing. You are left with a bigger tank of the same mix.
- Get the vehicle easy to see before anything else — hazard lights on — if there is traffic going past anywhere close to you.
- However short the way, starting it to move it is the mistake. At a forecourt, push the car away from the petrol pump by hand instead, then ask the attendants to lend a hand.
- Which fuel, and roughly how much? Your receipt replies that, and that's where our questions start. Never throw it away.
On the M25, under 3 miles from Havering-atte-Bower, the next exit is the spot to leave it; elsewhere, the first sensible location to stop. Don't push on to the services. Then go back to step one.
Each Havering-atte-Bower fuel drain starts here: has your motor run?
What comes next turns on one answer, and only one.
If it has never been started:
- Just the tank has petrol in it for now.
- Normally it is emptied and cleaned just where the vehicle is.
- This is the best position to be in, and the reason stage one counts.
If it has been started, even for a moment:
- Petrol has been pulled from the tank, through the filter then into the lines.
- A longer run carries it all the way to your high-pressure pump and your injectors.
- Distance is what turns it into a larger job: flushed lines, a filter seen to, and at times further work.
Why the line falls there: diesel lubricates the high-pressure fuel pump and the fuel injectors as it passes through them, and petrol does not. In your tank, sitting still, petrol does no harm. Once it is pumped, petrol begins wearing whatever moves it.
Before you call about petrol in a diesel in Havering-atte-Bower: what we need
Whether the technician circles or finds you comes down to a little planning.
- The best place to start is a postcode — one beginning RM4 1 — for where you are.
- The road or the car park. A road name is a help — North Road, or wherever you have pulled up.
- Name a car park by what it serves — the one outside Tesco, for example — and it's much quicker to find.
- The car. Make, model, plus that it's a diesel.
- Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Havering-atte-Bower page.
- The quantity: the receipt's litres, or else how long you had the nozzle in.
- Whether it's run. Then if it has, how far and how heavily.
- Whose motor it is. Some hire or company agreements want the owner to authorise this work, and that is easier settled before our engineers turn up than after.
Next, 0333 366 0103. Not time-critical, your car left at home with nowhere to be? Then works as well.
Havering-atte-Bower fuel drain on its way? Whilst you wait
Stick to these: well-intended help causes the damage during the wait.
- Wait with your car 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.
- Not to roll it a few yards, not to check it is all right, not as a passer-by's favour: no one starts it.
- Additives stay in your boot. Injector cleaner and two-stroke oil draw none of that petrol out once more.
- Siphoning petrol into a can at the kerbside is hazardous — and it still leaves whatever fuel has already gone beyond the tank. Do not try a home-made drain.
- Even your radio or your windows are not worth turning the ignition on for.
The fuel drain, step by step, after the van gets there
- Fuel, volume, whether it has run: those replies set the job, and that is why we give a quote after them rather than before.
- Out of the tank comes the polluted mix: your tank is drained.
- If it ran, the lines are holding petrol that has shifted beyond the tank — so they are flushed.
- Cleaned, or changed if the vehicle has a workable one: your filter is dealt with next.
- Priming follows once clean diesel is in.
- Our technicians fire it up only after new diesel has gone in and bled your system, then confirm that it's running smoothly.
Only once it's running on new diesel do our technicians head off. It's very rare for a car caught quickly to be left with long-term damage, and normal driving resumes at once.
Havering-atte-Bower, after your fuel drain: back on the road
- After it has been started on fresh fuel, there's nothing unusual to do: drive normally.
- Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or the throttle hesitating: pull over then call us back.
- The work may come up later with a hire company, an insurer or a fleet manager. Keep the paperwork.
- The handle's colour isn't the guide to go by next time — the label on the pump is.
