Jdawg70,
Welcome! I like you have a short trip to work. I have a '04 HCH that I averaged 48.5 on the last tank. This tank took a big hit last week when the morning commute was done near freezing. I am still trying and the FCD shows 48.4 right now.
This is a great board for tips and also seeing that you are not the only person that looks more at the dashboard than the road.
Good luck.
