Ok, I don't reset the trip milage very often but after reading this thread I wanted to see what I actually get on a short trip into town. Granted I don't live in a "city" but I pulled out of my garage with a "cold" engine (it's 85 right now outside) drive down a steep grade from my house, pulled out onto the highway at 55
mph and drove about 2 miles. I then had a 40
mph strech for a mile and then 25
mph strech for a mile to the store. It's rolling terrain and I had 1 stop sign and 2 red lights going and 3 red lights and 1 stop sign coming back. It's 8 miles round trip and I intentionally went the speed limit but drove "with purpose" other than driving faster than I normally do. When I got back to the bottom of my hill I had 40 mpg showing on the trip. By the time I got in my garage I had 36.5 mpg. (It's very steep and almost 0.4 of a mile.)
That is the same milage I got whem I drove through the mountains of WV and VA last month. It's what I think anyone can get that has the desire to achieve.
I believe most of the posts of people getting less that 36 mpg are from people with less than 1 tank experience or some of the folks who simply state they are happy with 34 mpg and drive the TCH just like a regular car.
A person seeking ultra high FE has to pay attention to their right foot and constantly adjust by letting off as much as possible to coast or simply allow the car to slow 1 or 2
mph over the distance of a half mile or so. I catch myself often driving along getting 20 mpg on the instant reading, notice what I'm doing and immediately I let off the gas pedal to shut off the ICE (or at least idle it) and then immediated "lightly" touch the gas to maintain speed. Many times the speed does not even drop but I'll go from 20 mpg reading to a 40+ mpg rating. That takes time to learn and it takes "attention" to details.
HOWEVER, I've said it before on this board, there is not a lot of gas savings between 36 mpg and 38 mpg so I don't even recommend this obsession for everyone. But I believe anyone should be able to get 36 if they really want to. Practice and paying attention is the key.
I will admit it's part of the learning curve watching the NAV Consumption and Energy screen but even with just the instant FE reading on the non-Nav system you can still learn to back off and on to maximize the FE.
