You'll find that EPA estimates for the 1992 Cadillac Seville typically ranged from around 16 to 20 mpg combined (city and highway). However, actual mileage would depend on driving style, vehicle condition, and other factors. You'll likely find lower mileage in city driving.
To get a more precise estimate, you'd need to know the specific engine size (e.g., 4.9L or 4.6L) and drivetrain configuration of the particular Seville.
