    45-70 is perfect. Pickups and SUVs start dumping fuel like a 767 as you move above 65.

    La Mirada? You've got to be dealing with the 5 or the 91.
    You have my sympathy. I lived in Brea and worked at Douglas... 91 sucked even back in 1990.

    I paid close attention to that loop indicator today. Every time it went into open loop at 1900 rpm (about 53mph actual in 5th). I tried it in 4th as well just before I got home and it was still 1900 rpm.

    So you 5MT guys, if you downshift to slow down, keep in mind that if its spinning 2000 rpm or more you're still burning gas.

    On another note, round trip to visit family this weekend was 190 miles; I set cruise at 72 mph actual o
    the way there and 68 mph on the return (75 and 71 on the dial) and the ultragauge is reading 23.3 mpg average. That should be close; last fill was 14.69gal, UG estimated 14.7. Last time I tried that with the six speed it said 14.6...ouch...

    Maybe you should buy a hybrid cuz why do u need good mpg in a truck? Seems like a waste of time. I just drive mine. Sometimes I get 19 other time 27

    The joys of lake effect snow prevent that. I often get to drive through snowfall that no hybrid (except a yukon) can traverse.

    If I could afford to move out of the snowbelt, I would SO have a civic hybrid. Cleaning deer blood out of the trunk would be a pain though.

    Besides, it's just the way I drive, no matter what it is... I enjoy the challenge.

    I would love it if they made a hybrid version of the 4 cyl Tacoma. It would boost power as well as MPG. In my current driving situation, which is 3.5 mile trips twice a days, never exceeding 40 MPH, I would gain 7 to 10 MPG because I would not be using fuel for over half my trip. Would actually buy one if it came in at $2000 or less extra. Beside it would improve the air you breathe. Just thinking and dreaming out loud.

    I dont plan to lift mine or anything. Women just got a Mazda so I'll mod that, I like my 10 year old truck thats being taken to the grave I'm keeping it till it's last breath. As for a 2nd vehicle I'll have a 2nd bike soon.

    I pay attention here and there, I have bad tanks and good ones it all depends if I rush or plan my trips I make.

    This and this^

    I always chuckle when guys on here get pissy about anyone mentioning fuel economy. I try to get the best FE out of any vehicle I drive, just for fun, and the cash saved is a perk. Plus tracking it lets me know what my vehicle is up to. Just wanted to share in the sentiment :)

    I like the challenge and tracking like you. It uses less gas but I actually get paid way more for the few miles I put on for work than I spend in gas. I gas up about every 6 weeks and with safeway discount a tank is less than $50. I average $80 a month for the 180 miles I put on for work.

    I also think it's patriotic to use less fuel if I can. :crapstorm:

    As you know, those of us who dabble about at CleanMPG.com try to drive our vehicles efficiently and effectively. Concern about our environment on a local and global scale is everyone's responsibility, but some folks contribute in different ways, at different points/times in their life, or not at all. Degrees of selfishness and awareness I suppose. But the challenge to do more with less should be a goal in many arenas beyond fuel efficiency. I see the folks in other threads mostly where they complain about a fellow enthusiast asking questions about fuel optimization as if they didn't know they bought a truck without regard for the circumstances. A bit a bravado and ignorance. Mostly have to ignore this as a good many of them will come to that 'point' and 'time' and realize the error in thinking. Also, these folks may be contributing in other ways to the common good of mankind. You never know. So as I don't presume to know all that they do, I ignore most comments. However, I have my moments of weakness where I'll throw in my 2 cents and hope for the best.

    Fuel Optimization: enjoy the challenge, the cleaner air, and the extra money in your pocket!!

    What point would we have in fibbing? Check out my and others Fuelly.com account. Some of us have made over 100 entries over several years and ten of thousands of miles. I just wish I got the 25+ I was getting, as my driving conditions have changed since last fall. Now 85% of my trips are less than 4 miles.

    My MPG seems to be picking up also. I was getting 170 to 180 miles at the half tank mark. Today at half tank, I had 195 miles.:)

    Gas mileage is picking up here too. Overall, I am seeing about 2 MPG increase.

    210 and not at the halfway mark yet. I haven't seen this for the winter, so I am wondering if I might be operating on real gas already. I didn't think that they switched back until the middle of this month, but maybe.

    have yall noticed a mpg increase using ethanol free gas? or is difference it very minimal if any? there is a station by me that is always one of the cheaper stations and has ethanol free gas and i was wondering if i should make a point to use it.

    IIRC winter blend is phased out slowly over several weeks. The refiners have access to long range weather forecasts for all regions, and adjust the amount of oxygenates that the fuel has in it during the switchover of seasons. The oxygenates cost more than pure gas, so it is to their advantage to use less if possible. I doubt if fuel in Mid to south Texas and Florida even have winter blend. Just my 2¢

    It can be significant.
    While Ethanol has a base octane rating of 118, making it a cheap octane booster that allows for more timing advance, it is stoich at around 9.5:1 compared to gasoline's 14.:1

    If you had two identical engines, one tuned for gasoline and one tuned for ethanol, if the gasoline engine got 29mpg, the pure ethanol engine would get 19mpg, and it would put out 25% less power due to ethanol's lower BTU content.

    That's comparing pure gasoline against pure ethanol.
    Pump gas is only around 10%, but the computer still needs to add more fuel to compensate for the lean burn.

    I understand ethanol's lower fuel content per volume compared to gasoline, and the resulting lower mpg numbers. But if ethanol is stoich 9.5:1 compared to gasoline stoich of 14.7:1, doesn't that mean more ethanol is added per volume of air compared to gasoline? If yes, wouldn't the additional ethanol balance out the otherwise lower power output of the ethanol engine? I just don't understand why an ethanol engine would put out so much less power if it's burning *a larger quantity of lower energy content fuel,* especially since an ethanol engine would be tuned to take advantage of the super high octane ethanol... wouldn't the power output be a wash for the most part? When I ask this question, I'm not considering fuel economy, only final power output of engines of equal displacement.

    Consider this: high-compression gasoline engines put out more power than a normal compression engine of the same displacement, while burning premium fuel which has no more energy content than regular gasoline.
