Gary,
Thanks for the additional info. The commute from Fremont to Omaha daily is a very ideal commute. Over 1/2 of the trip is on flat 4 lane. With it being a 4 lane, I can let the car 'die off' on the Elkhorn hill without presenting a road hazard. I travel early to work, and don't leave until after the peak rush.
When I finally made the decision to 'go for it', so to speak, I tried different things in steps to measure their value. I first started with slowing down. That moved me from 39-40 up to 45. Next came pumping the tires. I have always run at the max. recommended by the vehicle manufaturer (34), but moved them to the max. on the tire (44). That got me to 46-47. Lastly, I emptied out the car, and waxed everything, even the windshields. I have had 5 of the last 7 weeks at 47.xx, one week of 52.xx and one week of 54.14.
I am careful when I fuel to ensure I get everything in the tank I can get into the tank, that it is level when doing so. I have not had a 'swing' week, which would indicate a filling 'short' one week.
My mileage is very constant, week to week, so am fairly satisfied that I have achieved the max. this vehicle will produce short much more serious mods.
