You're off to a great start, Rikster! You should be able to stomp on us folks in the U.S. that can only get the 1.5L.

Hi, KrazyDawg. Using the SGII many of us have verified that 35-45 MPH is the sweet spot for efficiency on relatively flat roads. The 10 MPH difference is a broad range that depends on many factors such as tire pressure, road quality, wind resistance, ambient temperature, etc., but the common sweet spot within that range seems to be between 37-39 MPH.
