Welcome to GreenHybrid!
xcel would be your best goto guy.
What I can tell you now is get comfortable with your dashboard. Over the next few weeks or even months, it will reveal how fuel is wasted.
I'm a five-year Insight driver, but I thought someone said manual Civics have lean burn. The way to tell is to get up to 60mph on level ground and a light load. The fuel consumption bar should shoot up signifitantly unless maybe the A/C is on. It's about a 50% increase on the Insight.
I would not get too worried about 35mpg just yet. There are two break-in:
- The car itself
- The driver learning all the hybrid nuiances
