St Mary Cray: Petrol in a Diesel Car? Here Is What Happens
Not for a moment, and not for moving it: your engine stays off. Stop there. Cleared then flushed, just where it sits: that is usually all an unrun diesel with petrol in it takes. Whether it stays that simple depends on the minutes ahead far more than on anything else. Anywhere you are around St Mary Cray, here is the order things run from here.
Engine off: minute one with petrol in a diesel
Work through the following first, in this order.
- Keys out of your ignition. Switching your ignition on can be enough to prime the system, and priming draws petrol out of your tank towards the parts it harms. Leave the car off altogether.
- Don't top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture.
- Get the vehicle simple to see before anything else — hazard lights on — if there's moving traffic anywhere close to you.
- The staff will usually help you roll it away from the pump. Ask, then roll it by hand — not on your engine, even for a couple of yards.
- The first question you will be asked is which fuel went in and roughly how much — and the till receipt shows both. Hold on to it.
Still driving when you realised? Come off the M25 at the next exit if that's where you are, under 3 miles from St Mary Cray, and stop somewhere safe instead of pressing on to the services. Then begin at stage one.
St Mary Cray fuel drain: has your motor run yet, or not?
From this stage on, everything comes down to a single answer.
If it has not once been started:
- No place but that tank: that's where that petrol yet is.
- A drain and flush, on the spot, is usually all of that.
- Being here is the best case — which is the whole point of stage one.
If it's been started, even for a moment:
- From the tank, through the fuel filter, into the fuel lines: that is how far the petrol has travelled.
- The high-pressure pump as well as the fuel injectors get it on a bigger run.
- Mileage is what makes it a bigger job: flushed lines, a filter seen to, and at times further work.
Diesel keeps your high-pressure pump and the injectors oiled as it goes through them. Petrol offers them nothing, and that's why the line is drawn there. In the tank, left alone, petrol does no harm. As soon as it's pumped, petrol starts grinding whatever moves it.
Before you call about petrol in a diesel in St Mary Cray: what our technicians need
Prepare a little, and the technician finds you rather than circling.
- Where you have stopped. A postcode beginning BR5 4 is the ideal start.
- Wherever you have parked, the road's name is useful — whether that's Kent Road or somewhere else — and so does the name of a car park.
- Car parks are found most easily by what they serve: say the one outside Co-op Food, and it's simple.
- Make and model of the car, and the fact it's a diesel.
- Which got in counts: AdBlue is a separate job from petrol, and St Mary Cray has a page just for that. So say.
- The amount: your receipt's litres, or otherwise how long you had the nozzle in.
- Whether it has run. Then if it has, how far plus how heavily.
- Hire or company car? Some agreements want the owner's authorisation for this work, and sorting it before we get there is quicker than after.
Ring 0333 366 0103 once you've got that ready — or, if the car is at home, going nowhere, use .
Waiting for a fuel drain in St Mary Cray: what to do
Help, however well meant, is the thing that does the damage while you wait. So hold to these.
- Where your car has stopped decides where you wait. Somewhere exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before your car.
- No one starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a couple of yards.
- Something from the boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol.
- No DIY draining. Siphoning petrol into a can by the kerbside is hazardous, and it leaves your fuel that has already gone beyond the tank.
- Leave your ignition off — the windows and your radio included.
Van arrived? The fuel drain, one step at a time
- The quote comes after three questions, not before them — what got in, how much, and whether it has run — because those replies decide this job.
- Your tank is cleared. The polluted blend comes out of the tank.
- Flushing the lines comes next, because a car that ran has petrol past the tank, in the fuel lines themselves.
- Where the car has a workable filter, it's replaced; if not, cleared.
- Your system is primed with fresh diesel.
- The first start on new diesel. Once priming is done, the engine is started and we check that it runs correctly.
The car has new diesel running through it before we go. It is very unusual for a car caught soon to be left with long-term damage, and normal driving starts again straight away.
Back on the road around St Mary Cray after the fuel drain
- Started on fresh diesel, it needs nothing unusual of you. Simply drive normally.
- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop and ring us a second time.
- The work may come up later with a hire firm, an insurer or a fleet manager. Keep the paperwork.
- Next time, check the petrol pump. The label, not the colour of the handle.
