There is a tale out there that premium gasoline provides better gas mileage no matter what, but that’s not the case.
The kind of gas that a Cadillac CTS takes regular unleaded gasoline with octane 87. Premium gasoline does not actually do much for your engine; you may get better gas mileage with the recommended gas type. An extended fuel economy is important in today’s world of crazy-high gas prices!
