What oil do you use in a 1995 Buick Riviera supercharger?
The 1995 Buick Riviera with the supercharged engine (3.8L Series II supercharged) calls for SAE 5W-30 motor oil. However, it's crucial to check your owner's manual for the specific oil recommendations, as Buick may have specified a particular brand or type of 5W-30 (e.g., synthetic blend, full synthetic). Using the incorrect oil can damage the engine.
