However, generally speaking, a 1998 Chrysler Concorde would likely recommend something in the range of 5W-30 or 10W-30. 5W-30 is a good starting point for most situations. If you live in a very cold climate, 5W-30 is preferable. If you live in a very hot climate, 10W-30 might be slightly better, but again, check your owner's manual.
Using the incorrect oil weight can damage your engine, so consulting your owner's manual is crucial. The manual will specify the exact oil grade and viscosity recommended by Chrysler for your car.
