There are so many factors involved here. My method is to make this a grand science experiement everyday.

I find the biggest factor is how full the tank is and how many people you carry or the cargo. I am now trying to stay at about a 1/4 tank unless it is a distance between cheap gas stations. The load factor of the gas weight does make a big difference.

I live in high altitude (4,000+) and it seems to give me better MPG than most. But it is also colder here (30-50) and that increases the time until I start getting decent mileage after a cold start (5-15 minutes). From a warm start or idle the time is less than 3 minutes. When summer comes the MPG will increase quite a bit.

I have found from reading the elapsed MPG on the Nav vs. the old way gas in gas out measurement that the Nav underestimates. This is because is has no way of measuring gas actually used while sitting still.

I try to feather lightly the pedal and never use cruise. I never turn on my interior fan. I power slightly downhills and start to coast just before crests. I brake often as I go downhill to charge. I get into EV as often as possible and do not worry much about those behind me if on a four lane.

My average Hwy. is about 30 and have yet to get a good City. My FEH is still breaking in at 1500 miles. Overall I am averaging over 30.

I have tricked it out with a Covercraft Bra (for blowing sand) and Aries Step Sides (for a short wife). I hope to have a good Class II Hitch next week through Curt and Hitch-Web.Com (I'll let you know). Stay away from Ford for accessories. Most are over priced for both the price and install and most dealers are still clueless.

Hope this helps just a bit.
