For a 1998 Cadillac STS, it's recommended to use synthetic engine oil with a viscosity of 5W-30. Ensure that the oil meets the specifications set by GM, such as GM6094M or API standards. Regularly check the oil level and change it according to the manufacturer's maintenance schedule for optimal performance.
The Cadillac STS 98 was constructed to drive it in the Autobahns, so I reachs 241 km/hr or 150 miles /hr
it should, but the emissions regulations of the 2002 car are different than that of the 1998 motor
that depends on what kind of engine you're trying to get. Domestic? Foreign?
