Smell is going to be subjective but I personally couldn't handle it so I have HFC. Oil usage shouldn't change unless your driving habits do. Gas usage will decrease (+1-2 mpg) provided your driving habits don't change.

How old do you mean, the 08-09s? How do we get the newer software? is it a huge difference, very interested.
