Only two things can cause an engine to consume oil. 1. Leaks, or seepage, normally from the valve cover or oil pan gaskets, front seals, rear main seals, and sometimes around some cars timing belt covers. 2. The other is ring wear. When an engine's rings wear down, indicative of a compression ratio drop, and oil is able to seep past the rings and be consumed in the gas/air explosion and exhausted. If not too bad, then you only notice oil consumption. After a time though, you will see blue or black smoke at startup, or when you rev the engine up and down. This is unburned oil and usually raw, partially burnt oil, will be seen around the tailpipe. Also when this condition worsens you will see oil in your breather, pcv valve, and blow-by around the oil cap filler.

How much oil does a car use a year?
Depends on how worn the engine is. An engine in good condition won't hardly use any oil at all, maybe a cup or so, while there's virtually no limit to how much oil a worn engine can consume.
