My oil light came on before my oil change was even due and i checked it and there was nothing on the dip stick. I added 1 and a half quarts to refill. and now i have to add another only 2 weeks later. there is no oil on the engine, its clean, nothing underneath, and the antifreeze is clean too. WTH is going on??

Do you see any bluish smoke from your muffler? First easy and cheap thing to do, is replace your PCV valve...could be clogged. After that try a compression test, your valcve stem seals may have hardened and starting to leak.
