To change the oil depends on the engine model. Check your engine model first in the registration and go to the technical information in your BMW z3 booklet.
To compensate the leaks or oil consumption (oil burned in the engine) you have to check the level on the dipstick. The oil level in the engine (cold) should be between the two signs on the dipstick. Never over fill and use the same quality of oil.
A 1997 BMW 328i uses standard 10w-30 engine oil. This provides a good balance of protection and heat dissipation for the engine.
It has a M43B18 engine from 1993-1998
The oil dipstick on a 1997 BMW 528i is located on the left side of the engine. It has a tube which connects to the engine block and directs the dipstick into the bottom of the oil pan.
That's a tough one. The 528i weighs less, but has an engine with less torque and horsepower. Honestly none of those cars are exactly "fast." How about this, a 1997 540i has the same engine as a 1997 740iL and weighs less.

Yea but with some modification
The BMW M44 engine uses a chain to drive the two overhead camshafts. You can see a good illustration at http://www.realoem.com.
A 1998 BMW 740il requires 8 quarts of engine oil.
Back right hand side of engine should be red.....
Between 4 and 5 quarts of oil are needed in a 2006 BMW x3. The actual amount of oil needed varies based on if the filter is changed and the overall state of the engine.
