Wrong fuel question

You obviously didn't read the OP. He turned the ignition on and drove 30 meters across the forecourt out of people's way.

The engine will still have been running on the diesel in the lines and filter for that distance. Therefore no petrol will have made it to the engine. It might have sucked some petrol into the back of the lines, but this will have been mixed with the diesel when he refilled it, and probably diluted it to something like a standard winter diesel mix.

Fuel goes to the pump and then un-needed fuel is returned to the tank, so it swirls around. I've no idea at what sort of rate though.

We had people mis-fuel company cars and drive them until they stopped multiple times. Not aware of any problems up to the 90K we typically kept them. Maybe they died immediately afterwards though!

Fairly substantial. Enough that there are often coolers put in the return line. The lift pump runs all the time the engine's running - and it runs at constant flow. That flow has to be enough to not risk fuel starvation absolutely flat out, with margin to spare. So, in the time that the car's been started, and moved across the forecourt, there's a far-from-trivial amount of fuel flowed through the lines...

I read it quite well. If the engine had not been switched on there would have been no petrol in the lines, injectors or engine.
Once the engine is started and the car moved 30 metres all the lines will have the petrol/diesel mix in them, also the injectors and filter.

So where in this does it say the engine hasn't been switched on? Because it quite clearly states the car was drive, I highlighted that part, which would indicate it has been turned on.

After 6 years of driving my diesel Grand Cherokee, I finally did the wrong thing and stuck petrol in it the other day !
Realised straight away, drove it 30 metre's out of everyones way and just parked it up at the station. Had a company pump it out and filled it with fresh diesel and ran fine, and still is 25 miles later.

They kind of read you the riot act about what might or might not happen after doing this. One thing he mentioned was to replace the fuel filter (about £30 for this Jeep). Im happy to do that if required, but just thought the fresh diesel would wash through any slight petrol contamination and is it really necessary or just a hypothetical box ticking exercise.

Thoughts ?

I think we have some kind of language problem here.

I don't think so. You claim the engine was not switched on, when the original post says nothing of the sort.

Actually, you know what, I don't care.

This is such a crisis, it must be caused by climate change FFS.




Just fill the fking thing with diesel and drive it. It's fine and ignore all the bullst above.

A valid observation.
But where would PH be without doom, gloom & despondency
