I recently purchased my first cadillac. A 1994 Cadillac Concourse-170000miles+. I read many posts on this forum and before it took possesion of the car i started to worry. Oil leaks, oil burning, PRoblems,problems!! Im not sure if i am the only lucky one, but my car does not burn oil. From the looks of the engine(grime and dirt) i dont think it has had any top end work. I get an amazing 30-34mpg highway- with the cruise on at 60mph. I am so thrilled with how well it runs, and how it sips the gas i just had to post this to see if im alone or if im lucky and should buy the lottery.
