There's a low oil level warning light and a low oil pressure warning
light. You're referring to the latter and you're pretty much screwed
if that comes on anyway.
I know people who don't even know how to open their hoods/bonnets.
Usually by the time that light comes on, it's too late. Most of the
pressure switches don't activate until <10psi, and if you're at high
revs, that's just not enough to protect your big end bearings.
Even if the car still sounds fine after a top up, you've probably put
several thousand miles of wear onto the bearings in those few seconds.
I've even had cars that have run a bearing, and I've pulled over
because I've heard the noise, and only then has the light come on!
Never trust a light... The dipstick is your friend! Plus a dipstick
will also tell you if you have any water getting into the oil etc etc,
and sticking your head under the bonnet might help you spot all manner
of faults that might come and get you in the future. Oh, and find the
neighbours missing cat!
Another possibility is that the engine does use oil but it gets topped up by
fuel as certain % of fuel dillution can take place, especially when the car
is driven short distances. So, the level on the dipstick may remain
E46 2000 323i.
This is my first BMW, got it with 117k miles. Now has 126K, changed oil
once since I had it. Have to admit I am from an old school and changed
it at 5000 miles. I used the BMW oil, seemed cheaper than the local
auto parts store believe it or not. I am considering letting it go to
7500 between changes, again that may be wasteful again I am still old
school, I still check under the hood (bonnet) almost every weekend.
Since the switch to OEM synthetic oil around 1999, a BMW service indicator
will call for service (including an oil change) anywhere from about 13,000
to 18,000 miles, depending on how the car is driven.
Yes. Depending on the age of the car the service indicator computes the
service interval in different ways - but basically the result is the same.
A car driven gently with highway miles will go further before an oil
change is indicated than one which does short trips and/or is driven hard.

I got a 03 325i and never had to top off... I drive the car hard and never
had a problem with losing oil... the car has now 100,000 miles on it and I
just service it every 15,000 miles .... never had a problem...
