St Lukes: Petrol in a Diesel Car? Here Is What Happens

Pause, then keep the engine off — not on, and not for a moment to move it. Emptied then purged, just where it is: that's usually all an unrun diesel with petrol in it needs. Whether it remains that simple depends on the minutes to come far more than on anything else. Wherever you are in St Lukes, this is the order things go from here.

Petrol in a diesel, engine off — the first minute

Work through these in sequence, first.

  • Bleeding the system draws petrol from the tank toward the parts it damages, and turning your ignition on can be enough to do that. So the keys come out, and the ignition stays off completely.
  • Topping up with diesel sounds like it dilutes the problem. It doesn't: nothing comes out, and that tank simply holds more of the same.
  • Close to moving traffic? Then your hazards come on before everything else, so the car is simple to see.
  • By hand, never under your engine: that's how it comes off the petrol pump. Ask the forecourt attendants to help you roll, however short the miles.
  • Hold on to the till receipt. It shows which fuel got in and roughly how much, which is the first thing we will ask.

Still driving when you realised? Come off the M1 at the next junction if that is where you are, under 10 miles from St Lukes, and pull over somewhere safe rather than pressing on to the services. Then start at stage one.

The fork in every St Lukes fuel drain: has it run yet?

Everything after this stage rests on one answer.

If the motor hasn't run at all:

  • Nowhere but your tank: that's where that petrol still is.
  • Normally it is emptied and purged right where the car stands.
  • This is the best case — which is the whole point of step one.

If it has been started, even for a second:

  • The fuel lines and the fuel filter already hold petrol pulled from the tank.
  • A longer run takes it all the way to the high-pressure pump and the injectors.
  • Lines flushed, the filter seen to, and sometimes more: this job grows as the distance does.

That line falls there since diesel protects your high-pressure pump and your injectors on its way through them — and petrol does not. Nothing is damaged by petrol that's just resting in a tank. Move that petrol, though, and it wears the very parts doing the moving.

Fuel drain of a diesel car in St Lukes, step by step

St Lukes, petrol in a diesel: have these prepared before you call

Get ready a little, and the van finds you rather than circling.

  • Your whereabouts: a postcode beginning EC1V 8 works best.
  • A road name helps: Pear Tree Street, say, or whichever street you've stopped in. A car park does the trick too.
  • Or the landmark. A car park is easier to find by what it serves, like the one at City Road Supermarket.
  • Say what the car is — make, model — and confirm it is diesel.
  • Which went in counts: AdBlue is a separate job from petrol, and St Lukes has a page just for that. So say.
  • How much. Litres from your receipt, or how long the nozzle was in.
  • The miles it did, and how heavily, if it has run at all.
  • Hire or company car? Some agreements want the owner's go-ahead for this work, and getting it before our technicians arrive is faster than after.

Next, 0333 366 0103. Not time-critical, the vehicle parked at home with nowhere to be? Then will do too.

While you wait for a fuel drain around St Lukes

Help, however well meant, is what does the harm while you wait. So hold to these.

  • Where your car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety ahead of your car.
  • Not to roll it a couple of yards, not to check it is all right, not for a passer-by's kindness: nobody starts it.
  • Additives stay in the boot. Injector cleaner and two-stroke oil draw none of that petrol out once more.
  • No DIY draining. Siphoning petrol into a can by the kerbside is hazardous, and it leaves the fuel that has already gone beyond that tank.
  • Even your radio or your windows aren't worth turning your ignition on for.

Van arrived? Your fuel drain, one stage at a time

  • Three queries. What went in, how much, and whether it's run. Those answers shape the job, which is why the quote comes after them and not before.
  • Next the tank is emptied, so the contaminated fuel comes out.
  • Petrol that has shifted beyond your tank sits in the lines if it ran, and the fuel lines are rinsed to clear it.
  • Then the filter: changed where there is a usable one, cleared where there is not.
  • Priming follows once fresh diesel is in.
  • Our technicians start it only after fresh diesel has gone in and bled your system, then confirm that it is running properly.

Only once it's running on fresh diesel do our engineers leave. The vehicle goes back to normal use at once, and lasting damage is very unusual when it has been spotted soon.

St Lukes, after your fuel drain: back on the road

  • Drive normally. There is nothing unusual to do after it's been started on fresh fuel.
  • The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and ring us once more.
  • Keep your paperwork. A hire company, a fleet manager or an insurer may ask what was done.
  • The handle's colour is not the thing to go by next time — the label on the petrol pump is.
