    This morning was dry and 44F. I left about 10 minutes earlier and had an 8 mph tail wind. I made all of the critical lights.

    71.12 MPG! Wooooooot! At the mid point which is also the low point, I cracked 90MPG. Now looking for a route that will be downhill both ways. :D

    Next stop, 75 MPG.

    By the way, another new record for me was that the engine was only running 53% of the 39.34 km traveled. Much longer ign off coasts due to the tailwind and the LRR tires for sure.

    Drive home, 66F, Dry, 8 mph headwind, 65.84 MPG, top on.

    Latest round trip, 68.48MPG.

    Current Tank, 291 miles, 64.26 MPG.:D :D :D

    haha i wonder if it stops there... now I have to get a set of LRR tires on my next tire change.

    But wow I'm very impressed that half the time your engine is dead, oh my i guess that grille block allowed your engine to retain its heat while its at zero. In the hottest of the summer i predict you'll crack 100 just because you'll try harder for the triple digit score.

    Give it your best!

    I wouldn't be able to get engine off 1/2 time without the hills and a carefully planned route. Thanks for the vote of confidence in 100 MPG but that may just be out of my reach. The grille block does a fine job keeping the engine warm in all weather. I doubt I could ever overheat with the small amount of fuel that I use.

    The LRR tires are great but they are not for everyone. Less wet, dry and snow traction is what you give up. You should probably have snow tires for winter in Canada.

    This morning I tried yet another route to work, two new segments. The resulting 66.03 MPG at 50F convinced me not to try it again.

    The drive home was much more fun. 78F, calm, roof off, 68.38 MPG which bests my previous best by 2.5 MPG.

    That concludes my latest tank. 338.9 miles, 64.64 MPG. The forecast for the next week is cooler with lots of rain. I am hoping to stay above 60 for the next tank.

    do you plan to show us your map of the routes you take? Details on the road and such like that? I want to know how you think everytime you approach a situation and your actions for doing what you do for high mileage.

    Man if you had a better car of what you have now, what would it be?

    Here is my current route. When I choose a route it has a lot to do with the hills. I look for situations where I do not have to use the brakes. So long gradual downhills that dont end in a light or stop sign. Stops at the top of a hill, not the bottom.
     
  8. philmcneal

    philmcneal Has it been 10 years? Wow

    wow you have quite a long trip to work. Hm would you say your ratio to downhills vs uphills is the same when going to and from back? Or do you always try to downhill > uphill everytime even if it means changing the way you go back home even if it means adding more length to your trip? Since where I live no matter which routes I pick I'm always having the ,"what goes down must come up" kinda situation on my way back.

    wow didn't know google earth was a PROGRAM, thought it was a web site you go to. I'm downloading this nifty tool thanks!

    oh and a line that caught my eye which i will try to incorporate, "Stops at the top of a hill, not the bottom"

    I had a pretty good tank this time. I had 425.39 miles and used 9.97 gallons for a 42.66 mpg tank. I think I can safely say that summer blend is back. :D

    Hi Dan:

    ___Your route spec via Google Earth is pretty impressive. I might have to try that sometime …

    ___Larry, we need to get into the particulars of your commute and setup a bit in the very near future. I know there are a few more mpg’s just waiting to be discovered in that Saturn of yours!

    ___Good Luck

    If I can figure out how to get the Google Earth image posted in the thread, I have it saved on my computer and I'll get it posted. My route for work is 5.83 miles to my wife's work then another 9.14 miles to my work for a total of 29.94 miles round trip. Once a week I make a trip for groceries that is 18.06 miles round trip . Also a trip to church once a week at 9.64 miles round trip. I come up with 174.4 miles /week that are pretty much standard every week. Then there are the misc. trips that vary in length and aren't always made every week. I have been averaging around 420 miles roughly every 9 days. These miles are mostly on county roads with some state highways and very little city streets. The county roads quite often have stop signs every mile although a few have 2 mile stretches and 1 or 2 have stretches longer than 2 miles without stops. The state highway I drive on the most has a 7 mile stretch without stops. I have noticed though that stop signs aren't necessarily a bad thing. They give me a chance to, "Use the FAS Larry." :D

    Hi Larry:

    ___Here is a FAS solution I use on one of the Warmup P&G routes I have at my disposal that may be able to help you out somewhat?

    ___There is a 35 mph limited surface street/frontage road with no stop signs over a 1.9 mile distance about 1.5 miles from work. I am in a FAS as I enter this frontage road so I can coast through an S-Curve. Once I am down to ~ 10 mph and heading straight down the rest of the ~ 1.6 mile straight stretch, I pulse up to 52 mph with a tail wind and then FAS until I hit the stop sign ~ 1.4 miles away at ~ 20 - 25 mph. With a side wind, I need to get up to 55 mph and I hit that same sign at ~ 10 - 15 mph. A head wind and I cannot make it from 55 mph. Either way, the road is usually abandoned and even when there is someone behind, I am traveling 15 + over the limit to begin with and just 10 under at the end coming into that stop sign. Is there anything you can use on your route from my short segment description? In warmer temps, that one segment as described is worth ~ 60 - 80 mpg in the Accord depending on wind and temperatures.

    ___Good Luck

    I'll see if I can describe my route for you. I will be using Google Earth for the distances. First, I FAS down my driveway which is .04 miles long then I pop the clutch to start and travel .23 miles up to 55 mph and FAS for .49 miles. There is a fairly significant hill I have to go up so that by the time I get to the stop sign I'm going 20-25. I then turn left and accelerate for .2 miles up to 55 then I FAS for .82 miles. I then turn right and accelerate for .42 miles up to 55 once again then FAS for .6 miles. I then turn left onto a state highway and accelerate slowly(if traffic allows) up to 50-55 for 2.03 miles then FAS for up to 1.02 miles. This last FAS distance is only possible if I can make it through an un-timable traffic light and make a left turn off of the highway and onto the side street. Once off the highway I'm in FAS for .06 miles before making a right turn then continue for another .06 miles before turning into my wife's parking lot and contiuing .02 miles before turning left and continuing .01 miles to where I let her out. After dropping her off. I head back to the highway and go to my work. Once I get back on the highway, I have to travel as far as 6.88 miles before I have a chance to FAS again for about .3 miles. Sometimes this FAS can be longer if traffic permits. By the end of this last FAS, the speed limit has dropped to 45(from 55). I then travel another .57 miles and FAS up to the next corner which is .14 miles away. I then turn right and accelerate up to 35-40 for approximately .3 miles and FAS for .42 miles. I then turn left and accelerate up to 35 for .18 miles then FAS to the parking lot for .18 miles before backing into my parking space. WHEW! I think I just wore myself out. :eek: Do you see any room for improvement in this? I have been traveling this route since January. Before that, the route was basically the same except for it being 4 miles longer although the extra length didn't allow for any more FAS. I have been traveling this basic route for close to 4 years; give or take.

    Hi Larry:

    ___About that first stop sign. Any alternate route through a subdivision or a way to bypass that stop sign? Also, do you have to accel to 55 mph on all the side roads up until you hit the Interstate? The 6.88 miles before a FAS opportunity, what are your speeds and what kind of hills are you traversing? Any chance to DWL or sneak in a HS P&G or two? Also , only a .3 mile FAS from 55 + MPH? That one decel has to hurt quite a bit. After the .57 mile segment you can only FAS for just .14 miles? That ICE-On to ICE-Off ratio is a bit low as well? Sounds like traffic is really smashing your capabilities there :(

    ___As I continually find alternates, you may want to try to find some as well. Those 55 mph limited routes with heavy traffic appear to be killing your opportunities? Let me know as there has to be room for improvement. The Ranger can knock out 40 + segments in that kind of scenario unless traffic forces me to a non-steady up and down in the 50 - 55 mph range.

    ___Good Luck

    I can't by-pass the stop sign you mentioned. I forgot to note that all of the roads, except for the state highway and the .15 miles to get to my wife's shop, are county roads;basically rural in nature. Also, the last segment of accelerating to 35 just before getting to my shop, is in the small town where my work is.
    The .3 mile FAS from 55+ is because the speed limit drops from 55 down to 45. I figure that since I have to slow down, I might as well do it while FAS.
    The .14 FAS after the .57 mile segment is slowing down to make a right turn. There is a traffic light that is quite often red for me so I quite often have to stop before turning because of traffic. I also forgot to note that during the .57 mile segment that the speed limit has dropped again to 40 mph. Also, I sometimes have to maneuver around people that are turning left off of the highway;fortunately there is enough room to do this without going clear off the road.
    As for P&G,(I assume this is pulse & glide) the traffic in front and behind is usually heavy enough that I can't do this effectively. I will, however, keep an eye out more for chances to speed up while going downhill so I'll have more momentum to carry me up any hills come up. I already do this somewhat but again, traffic is the limiting factor.
    Many of the FAS segments on the rural roads have uphill portions in them which require starting the FAS at 55 to be able to make it to the next stop.
    I'm not sure if I mentioned this in any other posts but, in the time when I was calculating my mileage but not writting it down, my summer mileage would run 42-44 with tanks that would ocasionally vary up or down from that. As you mentioned, traffic is hurting me. Unfortunately there aren't any alternative routes to take for me to get to work or get home for that matter. I have tried various routes in the past and this one seems to be the best for mpg. Since there are around 1,000 people who work where I do there is a significant volume of traffic going to and coming from work. Again, let me know if there are any areas that can be improved. Even at 40+ mpg, $3/gal gas is still not cheap. :(

    71.7 MPG to work today, just barely beating the previous 71.1 record. After the drive home it will be time for a fill. I hope I can hold on to the current 65.7MPG tank. Still short of Tom's 66 MPG challenge but with the RE 92's still breaking in, I have a shot at it next tank. :D

    Thanks psy. I just lucked out having a good hypermiling route to work. I also leave for work at 6:15AM so there isn't much traffic to deal with. The drive home is more stressful. I leave at 4:30 PM which is early enough to miss most of the rush hour. If I could shift my work hours just one hour earlier it would probably be worth another 2 MPG.:D

    philmcneal Has it been 10 years? Wow

    yowzers, dedicated man for waking up early to save fuel too! I'm not there yet hehe.

    Then again beating the early rush must be less stressful too, you can relax before work starts I guess.

    If I drive the wife and I in and Im to be droped off Im here by 7:30am 30 mins before Im due to start. If I drive us in and drop the wife off shes in the office one hour before start time. Its just getting stupid. I refuse to leave before 6:30am anymore. If I leave at 6:00am Im still caught in traffic at two stop lights that should be great fas. As it is now our days are 11.5 hours long from the time we leave the house till we return home. Sad thing is I can still get in faster than many that live closer into the metro than we do. I truley wish i could find a job in my poverty ridden little town and cut the drive out of my life. Moveing closer into the Tulsa metro isnt a option. I wont live like a sardine in a tin. O well.

    I truley love to see the numbers the Desol post's.
