    That is way too much for a normal engine to consume. Most manufactures say a quart per 1000 miles is acceptable. I have changed the oil in my Toyota every 3,000 miles and it doesn't burn any oil at all.
    It is normal for an engine to require a little engine oil between services. For an engine to require excessive amounts of engine oil between services means the engine is either burning oil or leaking oil. Leaking oil should be pretty obvious, look for leaks underneath the engine at the oil filter, oil drain plug, and oil filter. Look for oil leaking from the timing belt cover area/timing chain cover and valve cover gasket. If an engine is "burning oil" look at the tail pipe and rear bumper for signs off discoloration or black oily deposits oil. Oil may leak down the valve guides particularly after the engine has been shut off and started from cold,if so blue oil smoke may be emitted from the tail pipe on start up, (this may also be noticeable if the car is left idle for a few minutes and then accelerated away for example after sitting at a traffic light). If the piston oil control rings are worn the engine normally smokes on acceleration. Oil control rings may fail due to an engine that has badly overheated or has had infrequent engine oil changes. Frequent oil changes with good quality oil is critical to long engine life. Perhaps changing oil viscocity to the next "thicker" grade would help.
