Yes, a Cadillac CTS can use 87 octane gas, particularly the models equipped with the V6 engine. However, for optimal performance and fuel efficiency, it is recommended to use premium gasoline with an octane rating of 91 or higher, especially for models with the V8 engine. Always refer to the owner's manual for specific fuel recommendations based on your model year and engine type.
