A 1992 Chevy Lumina's recommended oil type depends on the engine it has. There were several engine options available that year. To know for sure, you need to check your owner's manual or the sticker under the hood.
However, generally speaking, a 1992 Chevy Lumina likely used conventional 10W-30 motor oil. But again, consult your owner's manual for the exact specification. Using the incorrect oil weight or type can damage your engine.
