I really appreciate this forum and the willingness of you all to answer questions and also make me laugh! To be clear i wasn't thinking "Hell ya, that sounds like a great idea!" Actually my thoughts were...what is this dude talking about? If he's REALLY wrong than he is suggesting to his Cadillac customers to F-up their engines. They do sell LT4s in the CTS-Vs along with other V8s....He is adamant that Premium gas is a conspiracy. I wasn't nodding my head and agreeing with him...i was saying "really? Cause im certain the manuel says 93 oct top tier gas" This guy was smirking at me like i wasn't in on the secret😳. My first thought was...lets see what the forum says. Anyway thank you...part of me wants to contact Cadillac and let them know what this guy is telling people...he did give me his card if i needed anything...like a new engine i guess
