Mini Cooper oil light & not starting

I have a 2007 Mini Cooper with a manual
transmission, about 130k miles; on a drive
back home I noticed that the oil light kept
going off (and mostly during shifting) and
then went to a red oil light, after parking the
car and turning it off I noticed smoke coming
from the left side of the hood. And now trying
to start the car, it seems to turn over before
immediately stalling and shutting off. I’m
wondering if this is something that needs just
an oil change or something else? I’ve
checked and the car did have low oil but I
don’t seem to notice anything else wrong
with it otherwise.
