Cann Hall: Petrol in a Diesel Car? Here Is What Happens
Whatever you do, never switch your engine on, even for a moment, to move the vehicle. Pause; leave the vehicle off. The next few minutes decide it far more than anything else: petrol in a diesel still unrun generally amounts to draining then rinsing, on the spot. What follows is the sequence from here, anywhere in Cann Hall you are.
Engine off: minute one with petrol in a diesel
First, these — following this order.
- Take the keys out. Even the ignition on its own can prime your fuel system, drawing petrol out of your tank to exactly the components it harms, so keep it off entirely.
- No diesel on top. More fuel in removes none of that petrol — it just leaves you with more of the same mixture.
- Near passing traffic? Then the hazards come on before anything else, so your car is easy to see.
- The attendants will usually help you push it clear of the pump. Let them, and roll it by hand — never on the motor, even for a couple of yards.
- Keep your receipt: the grade and the rough amount are printed on it, and they are what we ask for first.
On the M11, under 3 miles from Cann Hall, the next exit is the location to leave the vehicle; anywhere, the first sensible spot to stop. Don't press on to the services. Then go back to step one.
Has it run yet? The fork in each Cann Hall fuel drain
What comes next turns on one answer, and just one.
If your engine hasn't run at all:
- Nowhere but that tank: that is where that petrol yet is.
- Draining and flushing, on the spot, is usually the whole job.
- No spot is better, and it is why the first stage counts so much.
Motor run, however briefly?
- The lines and your filter now hold petrol pulled from your tank.
- Run it farther and that petrol gets to the fuel injectors, having passed through the pump first.
- The farther it went, the bigger the job — the fuel lines, the filter, and sometimes more besides.
Petrol doesn't lubricate. Diesel does, oiling the high-pressure pump and injectors as it passes through, which is why the line sits where it does. Nothing is damaged by petrol that is just waiting in a tank. Pump that petrol, though, and it grinds down the very parts that move it.
Calling about petrol in a diesel from Cann Hall: what to have prepared
A van that circles against a technician that finds you: a little preparation is what separates them.
- E11 3 plus the rest of the postcode is the best way to start telling us where you are.
- Wherever you have pulled up, the road's name helps — whether that's Terling Close or somewhere else — and so does the name of a car park.
- Or the landmark. A car park is easier to find by what it serves, such as the one outside Spices of Malabar.
- Make and model of the car, and the fact it is a diesel.
- Which went in matters: AdBlue is a separate job from petrol, and Cann Hall has a page for it. So tell us.
- How long the nozzle was in, or the litres on your receipt — whichever gives us how much.
- Has it run? If so, tell us how far it got, and the way it was driven.
- Hire or company car? Some contracts want the owner's authorisation for the work, and sorting it before our engineers arrive is quicker than after.
Phone 0333 366 0103 then. Writing to works too if it can wait, with the car left at home, going nowhere.
Whilst you wait for a fuel drain in Cann Hall
Help, however well meant, is the thing that does the harm whilst you wait. So stick to these.
- Stay with the 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.
- Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a few yards.
- None of that takes the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives.
- A home-made drain misses the fuel that has already gone beyond the tank, and siphoning petrol by the road is dangerous besides.
- Leave the ignition off — your windows and the radio too.
When the van gets there: the fuel drain, step by step
- Three questions. What went in, how much, and whether it's run. The replies set the job, which is why the quote comes after them but not before.
- Out of that tank comes the contaminated blend: the tank is emptied.
- Flushing your lines follows, since a car that ran has petrol past that tank, inside the fuel lines themselves.
- Cleared, or replaced if the car has a usable one: the filter is dealt with next.
- Fresh diesel goes in, and your system is primed.
- The first start on new diesel. When bleeding is done, the engine is started and our technicians check that it runs properly.
Till it runs on clean diesel, our engineers stay with it. Long-term damage is very unusual if it has been spotted soon, so your car can go right back to normal driving.
After your fuel drain: back on the road around Cann Hall
- Drive normally. There's nothing special to do after it's been started on fresh fuel.
- Pull over and call us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot.
- An insurer, a fleet manager or a hire firm may ask what was carried out, so hold on to the documents.
- Next time, go by the pump's label instead of the colour of its handle.
