Or if not what would the harm be in running the cheap-o oil? the oil burns off prety quick, and i cant afford to continue putting the good stuff in it. Thanks!

So... what you're concerned about is the fact that you are using oil. The smoke isn't an issue for you. Right?
How much oil are you going through?
Do you live in a cold area?
BTW... Welcome to AFs!
