Hi, unleaded over 92 octane is good but you can run 89. Change oil very often if you have supercharger SSEI
To check the supercharger oil on a 1998 Buick Riviera, locate the supercharger oil reservoir, which is typically found on the supercharger itself. Remove the fill cap and visually inspect the oil level; it should be within the designated marks on the dipstick or fill neck. If the oil level is low, use a suitable supercharger oil, which is generally a synthetic oil specifically designed for superchargers, often with a viscosity of 5W-30 or similar. Always refer to the owner's manual for specific oil recommendations and capacities.

A 1999 Grand Prix GTP uses an EATON M90 supercharger that displaces 90 cubic inches of air during every revolution. This results in a rating of 240 horsepower at the crank at 5200RPM, and a "pavement pounding" 280ft-lb of torque at 3600RPM!
