From the information provided about your Saturn L300 it appears that oil and coolant are indeed mixing and this is not a good thing. Usually when oil and coolant mix, this is an indication of a leaking or blown head gasket. However, this is a major repair. To be certain that this is indeed the problem your Saturn is experiencing, it is best to enlist the assistance of a certified mechanic to come inspect your antifreeze reservoir, drain it, and locate any leaks that may exist.
