You'll need to have it diagnosed to know for sure, but there are a few things that cause an engine to use oil. They normally involve oil leaking externally or an internal oil leak into the compression chamber. Here are some possibilities:
1. External Oil Leakage
2. Worn piston rings
3. Worn Valve Guides
4. Malfunctioning PCV System
