Take heart, because you might have done better than your calculations show. We just can't know. Ninety-eight miles distance and about three gallons is not enough to give you a good chance at an accurate calculation with the crude equipment we have to work with. Pump variations as to when they click off can completely throw off your calculations. Easiest recommendation is that you wait until as close to empty as is safe and practical and then refill, that you refill at the slowest fill rate setting, always use the same pump, and stop fueling at the first click (don't "top-off").

You pumped up the tires? You are driving slower? Speeds like 60/65mph on the freeway? Not warming up the car before driving and other things? If so you'll see benefits as long as you are not racing around the city streets.

Good luck... getting it right takes some time... you have to enjoy the process in order to stick it out. And don't let mod-frustration cloud your enjoyment of a lovely new car. It's a privilege. So dig it.

[EDIT: START A FUEL LOG HERE AT EM! Enter gas prices as well as your other fill data and the EM fuel log will show you an estimate of savings. Psychologically, seeing the slowly mounting savings estimated will help you find the cash for that ScanGauge! Eventually!!]

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
