    Or course, until the more fuel effiecent vehicle comes, I will do what I can with my SIlverado. I know this is nothing to most of yall outthere but I was able to Go from Moore OK to Pearl MS with one tank. This is the 1st time I have ever been able to reach 600miles on one tank. When I made the same trip last year I got 22.1mpg, yesterday I got 23.1mpg. I think what probably allowed me to get the increase mpg was my speed. I kept my speed at 60-65 on the interstate (speed limit 70mph). My wife has also become more tolerable of my efforts, Last year she demanded I go the speed limit, now she lets me drive under.

    One thing that hurt me, the walmart I usually fill up at in Moore OK just made the switch to 10% EtOH. I bet I could have gotten atleast 23.5 w/o the EtOH. There are several stations in town that still sell the pure stuff, but it is usually 20cents/gal higher.

    Great. Glad to see that you are improving. The FE is pretty decent for such a large and "square" vehicle.

    Since wind resistance increases with the square of speed, you can still find considerable improvement by driving still slower. The improvement achieved by sticking to 55 MPH is clearly noticable, and it doesn't make much difference in arrival time. Also, check your tire pressure and make sure you are up to max sidewall pressure.

    Good work!

    Good job deleond2. Hypermiling is about gettting the best mpg that you can in
    whatever you drive.

    My truck's sweet spot is at approx 40mph so I try to keep at that, when I'm driving alone I will slow to 55mph. There were two reasons why and didnt drive below 60mph on yesterday's trip.....

    1. Traffic
    2. Wife

    I'm sure reason #2 supersedes ALL else.

    Well the difference in arrival time is worth it to some. Going 55-65mph instead of 65-70mph on my daily 18 mile commute shows no big difference.

    But when the trip is all hwy, it can make a difference. 600miles/60mph=10hours. 600miles/70mph=about 8.5hrs. When I told my wife that we may be late for dinner since I'm driving slower, she got pretty frustrated.

    I have P265/70/17 Firestone Destination A/Ts, I run the pressure at max (give or take a few PSI). The pressure was 45psi the morning of the trip.

    I have mentioned my wife several times, In all fairness, my wife is probably frustrated because alot of this stuff is relatively new to her, she is not used to my driving techniques. Regarding the use of the A/C, If I was 30wks pregnant, I would probably want to keep the A/C on too.

    Took my wife a while to grow accustomed to my hypermiling. I even got her beating the EPA by about 10 MPG. My 27 mile daily commute is mostly highway and it only adds about 5-7 min. (Only about a mile is under 50 MPH.)

    A pregnant wife supersedes any and all hypermiling techniques.

    Hi Damionk:

    While a pregnant wife supersedes any requests of any nature (unless it's to please her immediate needs ;)), remind her that hypermiling is a much safer way to travel the highways and byways and the little one inside deserves her adherence to the PSL at a minimum for a long and fruitful life!

    Good Luck

    The wife is slowly coming on board. She is really beginning to pay attention now that I'm slowly beginning to hypermile with her 2006 Ford explorer. GIven what I can do with her 2006, I'm excited what kind of things could be done with some thing like the 2011 Ford explorer.

    Thanks from a newbie for this article and this site in general. One question:

    Does the "Prius II SHM" method still apply to the 2010 Prius (3rd Gen)? And if so, are we still shooting for the same numbers on the scangauge?

    Thanks,
    EZ

    Hi Ezanker:

    Good question and hopefully the following will answer your questions succinctly :)

    2010 Prius-III_P&G,_SHM and_WS_FE techniques rehashed, defined and refined

    Let me know if you have any other questions.

    Delond2, I cannot wait to drive the 2011 Ford Explorer with the 2.0L EcoBoost myself as I suspect it may be a real winner vs. the std. 3.5L.

    Good Luck

    XCEL....
    My wife is working half time, so she can be mom as much as possible on the side. I can have the small car to commute but she will need the kiddo mover. My wife is a big Ford Explorer fan and she is liking the 2011 explorers so far. It would probably be about 3-4 yrs before she would get a new car/suv, but if reliability holds up, I would push for the explorer to have the 4-cylinder turbo (1/2 the size of the 4.0L V6, power is better, better efficiency).

    Thanks! That article certainly answers my immediate questions. Once i receive my scangauge i will will start applying the shm technique and see what questions arise...

    How about some more articles on hypermiling with a TDI?

    After reading the article on hypermile I am stuck at 47 mpg for a yaris m5spd. Can anyone offer anymore suggestions to improve mpg. I have trying to shift at lower rpm.
    When I get up to 2,000 rpm, I shift into next gear

    My car is a manual 5 speed. Just driving a gear lower at 30 or 40 mph gives me another 10 mpg. For example Driving 40 mph in 4th gear was 54 mpg and now driving 40 mph in 5th gear (1500 rpm) is 65 mpg. Going up a steep hill would require shifting from 5th to 4th gear .

    Trying to maximize mpg keeps driving interesting.

    '13 Yaris EPA 30/37/33 with M5, so I'd say 47 (142% x 33 combined) is a great start.

    Low rpm, high load is usually the right path.

    You could start your own thread and lay out your driving patterns and current techniques.

    We do have some here who meet or beat 200% of epa with the stick, using advanced techniques in favorable conditions. That won't work for all of us.

    Yaris12 , you are doing great ! Wish I had a good ole manual trans instead of this ole automagical slushbox thing.
