Vacuum leaks are going to be your worst enemy on the Milly S. Fix all the vacuum leaks and that alone will bump your mpg up 2-3 mpg. Also, driving with a heavy foot on the Milly S will really drop the mpg downward.

If there is not check engine light illuminating, should I assume there is no vacuum leaks? My Milly has a weaker sound compared with the engine of my friends', but they are using normal engines.
