Alright a bit OT!! but my ditzy daughter for some unknown reason went
and dumped around a litre of Antifreeze down the oil filler of her
Mondeo earlier. Fortunately she realised her mistake and some muggins
looks like having to do an Oil change tomorrow;(.

If she had run the engine would this have harmed it at all?.

Never heard of anyone doing this before always a first time I suppose!
Anyone any ideas on what the outcome might have been if it had been
started?..

TIA......

I doubt if a simple drain down will be good enough. It would be worth giving
the engine a good clean with flushing oil before putting in new oil. This
will clean out the antifreeze and leave a clean sump for the new oil.
Flushing oil always seems a bit expensive since you only use it once and
then throw it away but the results can be very impressive. And it's much
cheaper than a new engine.

I sort of agree.

What I would do is drain, refill with the cheapest oil thati s useable, run
till warm at very very low rpm - Ticvkover - drain while warm then refill
with good stuff and fit new filter at that point.

Bearings stand up to running without any oil but the fiilm on them for
quite a while if not stressed.

The antifreeze will boil and spew out of a hot engine via the crankcase
breathjer points...so getting rid of most of it, evaporating the rest, and
draining the residue is what sems best to me.
