The Rise: Petrol in a Diesel Car? Here Is What Happens
Not for a second, and not for moving it: the motor stays off. Stop there. Petrol in a diesel that has not been run is usually a simple drain plus a flush, done right where your car sits, and what you do in the coming few minutes decides that far more than anything else. Below is the order from this point, wherever around The Rise you are.
Petrol in a diesel, engine off — the first minute
Work through the following in order, first.
- Pull your keys out. Even your ignition on its own can prime your fuel system, pulling petrol out of the tank to precisely the components it damages, so keep the vehicle alone wholly.
- Do not top it up with diesel. Adding diesel takes out nothing. You are left with a bigger tank of the same mix.
- Close to moving traffic? Then your hazards go on before anything else, and so the car is easy to spot.
- By hand, never under the motor: that's how it comes off the pump. Ask the forecourt attendants to help you roll, whatever the mileage.
- Hold on to the receipt. It says which fuel was put in and roughly how much, which is the first thing we'll ask.
Still driving when you realised? Come off the M3 at the next exit if that is where you are, under 3 miles from The Rise, and stop somewhere sensible instead of pressing on to the services. Then begin at step one.
The Rise fuel drain: has your engine run yet, or not?
From this point on, everything comes down to a single answer.
If the motor hasn't run at all:
- Only that tank has petrol in it for now.
- Where the vehicle sits is usually where the work happens: a drain, then a flush.
- This, here, is the best position to be in, and the reason stage one counts.
If it's been started, even for a second:
- Out of that tank, through your filter, into the fuel lines: that is how far the petrol has travelled.
- A longer run takes it right through to the high-pressure fuel pump and the injectors.
- The job expands with the distance — lines purged, filter seen to, occasionally more.
Petrol doesn't lubricate. Diesel does, oiling the pump and injectors as it flows through, which is why the line falls where it does. Petrol resting in a tank harms nothing. Once it is pumped, petrol begins wearing whatever moves it.
What to have ready when you call about petrol in a diesel from The Rise
A little planning is the difference between a van that finds you and a van that goes round.
- The best start is a postcode — one beginning SL5 0 — for where you have stopped.
- A road name helps: Park Drive, say, or whatever street you've stopped in. A car park does the trick too.
- Describe a car park by what it serves — the one at Waitrose, for example — and it's far easier to find.
- Tell us what the vehicle is — make, model — and confirm it is diesel.
- Which went in counts: AdBlue is a separate job from petrol, plus The Rise has a page just for that. So say.
- The amount: the receipt's litres, or else how long you had the nozzle in.
- The mileage it did, and how heavily, if it has run at all.
- Whose car it is. Some hire or company agreements want the owner to approve the work, and that is easier settled before we get there than after.
Next, 0333 366 0103. Not pressing, your car parked at home with nowhere to be? Then will do as well.
Waiting for a fuel drain around The Rise: what to do
The wait is where well-meant help does the damage. Stick to these.
- Safety before the vehicle. If it has stopped somewhere dangerous, get yourself away from the traffic then wait away from it. If it's safe where it is, stay with it.
- A kind passer-by doesn't fire it up. Nor does anybody checking it still works, or moving it a couple of yards.
- None of that gets the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.
- A DIY drain misses the fuel already gone beyond the tank, and siphoning petrol by the road is hazardous too.
- The ignition stays off. Even for the radio or your windows.
The fuel drain, step by step, after our van gets there
- Fuel, amount, whether it's run: those replies decide this job, and that is why we give a price after them instead of before.
- That tank is drained. The tainted mixture comes from that tank.
- If it ran, the lines are carrying petrol that has shifted beyond that tank — so they're purged.
- The fuel filter is seen to. Cleared, or changed where your car has a serviceable one.
- Priming follows after fresh diesel is in.
- We start the engine only after clean diesel has gone in and primed the system, then make sure that it's running smoothly.
The car has clean diesel running through it before our technicians head off. If it has been noticed quickly, long-term damage is very rare, and the car goes back to normal use straight away.
Once the fuel drain is done: driving around The Rise a second time
- Nothing special is needed after a start with fresh diesel — usual driving will do.
- Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over and call us back.
- The work may come up later with a hire company, an insurer or a fleet manager. Hold on to the documents.
- Next time, go by the petrol pump's label instead of the colour of its handle.
