05 Cadillac Cts Motor Oil. I've read that these cars consume a lot of oil and read that there seems to be issues with timing belt/chain. Historically, it was priced similar to cars on the compact luxury spectrum; but it has always been sized closely to its mid-size rivals.
A key maintenance practice is to change your engine's oil as specified in the owner's manual. This filter helps protect against engine wear by screening out. To borrow a phrase from another General Motors division, this is not your father's Cadillac. . . not by a long shot.
The car is really sweet, just a little nervous.
