Southgate: Petrol in a Diesel Car? Here Is What Happens
Stop, then keep your engine off — not on, and not for a second to move the car. The coming few minutes determine it far more than anything else: petrol in a diesel still unrun usually comes down to emptying then rinsing, right there. Anywhere you happen to be in Southgate, this is how things go from now.
Petrol in a diesel? What to do in minute one
Work through these first, in this order.
- Take your keys out. Even the ignition by itself can prime the fuel system, pulling petrol out of your tank to precisely the components it harms, and so leave it off completely.
- Topping up with diesel seems like it thins the problem. It does not: nothing comes out, and your tank just carries more of the same.
- Get the car easy to see first — hazard lights on — if there is traffic going past anywhere close to you.
- By hand, never under the engine: that's how it leaves the pump. Ask the forecourt attendants to help you roll, whatever the mileage.
- Which fuel, and roughly how much? Your receipt answers that, and that is where our questions start. Do not throw it away.
Realised on the move? Get off at the next junction if you are on the M25, under 5 miles from Southgate, and pull over somewhere sensible — not at the services further on. Stage one starts after that.
Has it run yet? The fork in every Southgate fuel drain
Everything after this point depends on one answer.
Not run, not even once:
- All the petrol remains in the tank, and just there.
- Usually it is emptied and flushed just where your car stands.
- Step one counts for exactly this reason: it's the best spot to be in.
Motor run, even briefly?
- The fuel lines and the filter now hold petrol pulled from the tank.
- On a longer run it has reached the high-pressure fuel pump and the injectors.
- Distance is what makes it a larger job: the lines flushed, a filter seen to, and at times more than that.
The line falls there because diesel protects your high-pressure pump and the fuel injectors on its way through them — and petrol doesn't. In your tank, left alone, petrol does no harm. Once it's pumped, petrol begins wearing down whatever moves it.
Calling about petrol in a diesel from Southgate: what to have ready
Get ready a little, and the van finds you instead of circling.
- N14 6 plus the rest of the postcode is the best way to start telling us where you are.
- The road or the car park. A road name helps — Blagden's Lane, or wherever you have pulled up.
- Describe a car park by what it serves — the one at Fio's Continental, for instance — and it is far quicker to find.
- The make and model of the car, and the fact it is a diesel.
- Say which was put in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Southgate.
- How much. Litres from your receipt, or how long the nozzle was in.
- Has it run? If so, tell us how far it got, and the way it was driven.
- Settle who owns the vehicle before we arrive: some hire or company agreements want the owner to authorise this work, and that is faster beforehand.
Phone 0333 366 0103 once you've got that together — or, if your car is at home, going nowhere, use .
Southgate fuel drain on its way? Whilst you wait
In the wait, the damage comes from well-intended help — which is why these count.
- Wait with your car if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it.
- A helpful passer-by does not start it. Nor does anyone wanting to check it still does the trick, or moving it a few yards.
- Additives stay in the boot. Injector cleaner and two-stroke oil draw none of the petrol out again.
- No home-made emptying. Siphoning petrol into a can by the kerbside is risky, and it leaves the fuel that has already gone beyond your tank.
- Not for your radio, not for the windows: your ignition stays off.
Step by step: the fuel drain when the van gets there
- Three questions. What got in, how much, and whether it's run. The answers decide the job, which is why our price comes after them but not before.
- Emptying it's how the mixture gets taken out of your tank.
- If it ran, your lines are holding petrol that has moved beyond that tank — so they are cleaned.
- Where the vehicle has a workable filter, it's replaced; otherwise, cleared.
- The system is primed on fresh diesel.
- Our engineers start the car only after fresh diesel has gone in and bled the fuel system, then make sure that it's running properly.
The vehicle has fresh diesel running through it before our engineers go. The vehicle returns to normal use straight away, and long-term damage is very unusual if it has been spotted early.
After the fuel drain: back on the road in Southgate
- Drive normally. There's nothing unusual to do after it's been started on clean fuel.
- Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or the throttle hesitating: pull over and ring us back.
- An insurer, a fleet manager or a hire firm may ask what was carried out, so hold on to your paperwork.
- Check the label on the petrol pump next time, not the colour of its handle.
