usually it is because a seal going bad, you should also check to see that your oil filter is snug and not loose. there is a product out that tries to seal the leaks if they are small but there are some side effects, like clogging up stuff over time, take it to a shop and have them check to see if you need new seals or tighten the oil filter. Usually not a major problem, unless you have run your car really hot and it started leaking after that.
If you have a minor leak.... they you can try one of those oil additives, might do the trick.
If you haven't already, do not change over to a synthethic oil. They are notorious for cleaning away deposits that have been blocking bad seals.... My car leaked like there was no tomorrow when i changed over...... (oil pan gasket)
To do list:
UUC System U TDM- 3/05
M50 manifold converstion 3/05
off to the tuning shop for custom software 4/05
Cams/lightened flywheel, throttlebody........ well lets see what happens
The engine can leak in many places. Head gasket, valve cover, shaft seals, oil pan, filter, hoses, etc. The point is, get under the car and look. If you don't know what you are looking at, take it to someone who does. All of it can be fixed. Some probelms cost more to fix than others. A head gasket will cost much more than tightening your filter housing.
I have a small leak somewhere. I'll be under the car this weekend.
Any engine of any manufacture can leak oil. Anywhere there is a gasket, you have a potential leak problem. It doesn't matter if it is a Ferarri, a BMW, a Toyota Echo, or a Lada. Some leaks are cheaper to fix, others more expensive.
Mine leaked becuase my drain plug needed to be replaced. No, seriously it was a $5.00 fix.
park you car in the garage over a piece of cardboard and let it sit. mark where the wheels are and figure out what's actually leaking from the cardboard. If it's the plug or oil filter, its easy. There will always be some gunk build up on the underside of the motor. It's grease/oil/road crap/etc. If the car doesn't leak but eats oil, you have an internal problem which has a couple of solutions.

First of all, no ghead shit any car can have an oil leak.
The question relates to whether it's common or expect of a bmw engine to have weak seals.
In case you haven't noticed some cars tend to have a popular/trendy problem. Certain cars have shitty transmissions. Certain cars have a STRONG engine block. Certain cars have crappy interiors. Ceratin cars paint jobs don't last long. ETC ETC ETC.......
Anyone else want to try to answer the question again?
I'm curious to know what BMW's weak points are myself.
I looked at tonnes of BMWs, engine bays, underside and all, when looking for my car.
I think overall 318s aren't leaky but don't be surprised to find leaks from car to car. There was a number of cars I found at dealerships that have had big oil stains on the underside but typically most of them are spotless clean (of course that can also mean that the dealer cleans their cars before sale ).
My 318i has no oil stains whatsoever except a bit around transmission housing. I'm not concerned as it's not really a 'leak'. It's just a bit moist and I've never seen it drip. I've also changed to fully synthethic oil and had no leaks and no extra oil used in three months.
All things considered, I think they are not typically leaky cars but of course that varies from one to another. Just have a hard look if buying.
