It all depends on your driving conditions. Colder weather places (-20s) require a somewhat heavier weight 5W-30 and hot weather places (0 and above) require a somewhat lighter weight 10W-30. And it all depends on the mileage of the car, if it has close to 100,000 miles I would put a high mileage oil because they come with certain addatives to restore engine wear and help the engine last longer.

A 1998 Dodge stratus 6 cylinder usually uses 10W-30 oil, but again it depends on what is your preference in your automobile. There are some Dodge Stratus 6 cylinder owners who prefer using 5W-30.
