Cruising at highway speeds for an extended period of time (like an hour or more) can also clean the engine's built-up deposits and is easier on the engine in the long run. Plus, you will heat the oil up to remove deposits and bring your battery charge up (esp if you do a lot of city driving and/or short trips). Besides, a road trip in the ole benz in a lot of fun!
