2012-07-05 451 9.42 $3.39 47.88 "Started using Pulse and Glide and DFCO. Still alot of improvement needed with my skills and route. Pulse from 50 to 60 mph. Trying my best to average or exceed 55 mph."
2012-07-14 432 9.07 $3.39 47.63 "Loving using DFCO. I am finding ways to use it everwhere I go. This tank had alot of potential. Scan guage was reading my average tank over 50 mpg, but then I had to take a trip across town with my wife who was unwilling to deal with a glide going under 55 mph and required AC. Maybe next time..."
2012-07-28 486 9.36 $3.49 51.92 "228171 - Got lucky with following some large tucks up some large hills. Also installed plexiglass upper grill block. Upper grill block made a huge difference."
2012-07-30 434 8.43 $3.49 51.48 "Still trying to master pulse and glide and drafting. Sometimes I get huge gains wile drafting at higher speeds, other times it is less effective. Just have to figure it out. Lower gill block installed for last 60 miles of this tank."
2012-08-09 521 9.27 $3.79 56.2 "Using nearly full grill block now. Seeing drastic differences in my coasting and DFCO."

2012-08-17 487 8.32 $3.79 58.53 "Got better gains with LRR tires. Was hoping to have a 60 mpg tank, but a couple bad run ins with traffic and non ideal situations ruined that Maybe next time!"
2012-08-21 506 8.87 $3.69 57.05 "This was mostly higher speeds of 70-75 mph going to and from the DSM shootout in Norwalk. Alot of drafting and higher speeds when possible. Suggestion to all who draft, install a CB and ask permission to do so. It works out really well and you have some interesting conversatons with truckers. I was very happy with the results."
2012-09-07 487 8.7 $3.95 55.98 "Removed my front skirt and lawn edging in prep for engine swap, lowering and alignment. Removing the lower air blocking really reduced the length of my EOC. Also, colder weather."
2012-09-12 137 2.41 $3.95 56.85 "Fresh fill up after new engine swap. A little wasted fuel in the process from having to disconnect the fuel lines"
2012-09-19 438 8.68 $3.89 50.46 "Lots of testing trying to engage lean burn with not much success."
2012-09-26 445 9.14 $3.89 48.69 "Found out I need to got 75 mph to engage lean burn. Average speed of thid tank was probably 70 with little to no eoc or DFCO. Lots more learning and testing to do."
2012-10-01 538 9.32 $3.59 57.73 "Trying to maximize gas mileage. I had several 60 mpg trips, but hit some traffic to ruin the tank. Mainly lots of pulse and glide with DFCO. Used lean burn going 60 mph in 4th gear at about 2100 to 2200 rpms going up hills and slight inclines. Only a few instances of EOC becasue I did not want to prolong getting back into lean burn to go up hills."
2012-10-03 509 8.94 $3.59 56.94 "100% highway and nearly 100% lean burn. I started off in lean burn at 2100 rpm and after about 20 minutes of lean burn I was forced to stay above 2350. Most of the time was right around 2400 in 4th gear going about 60 mph. Trip there was 59.78 mpg. I was climbing up to 60 mpg and then hit a patch of slower speeds with light traffic which knocked me out of lean burn. The trip home was worse. Either there grade was a slight incline or wind was a factor. Really struggled to keep it the MPG decent. Ended up being 55 mpg on the return trip. Still pretty cool I was able to just get on the highway, maintain a steady speed, and get decent mpg. loving the lean burn!"
2012-10-11 566 9.64 $3.53 58.71 "Just trying to optmize my route better. Loots of pulse and glide, lean burn in 4th up hills, DFCO, and a few EOCs. Added the front bumper skirt and lawn edging back on as I have not had time to lower the car yet... Lowers the resistance alot and saw a big coasting"
2012-10-13 632 10.52 $3.69 60.08 "My first 60 mpg tank!!!!!!!!!!!!! All the stars aligned and I had low RPM (1900 to 2100) lean burn in 5th gear. About 400 of these miles were going 57-63 mph on the highway in 5th gear lean burn. It actually was staying around 63 mpg, but I hit some bad traffic. $~@#$ construction!

Car still is really picky about entering at lower RPM, but once it does, it will stay in for 150 miles or more! Finally, the true test of the lean burn at highway speeds!

I am still questioning the size of this fuel tank. I have never seen a fuel light come on. Not sure if it is an option on the CX or HX. Would have been nice to test, but I don’t like running really low on fuel."
2012-10-25 557 9.17 $3.05 60.74 "I had some down time on the car and was driving my trick and accord alot this past week. End result is the car is now lowered on Tein S springs. About a 2 inch reduction and hardly noticable from an appearance stantpoint. Car rides much stiffer and coasts easier. Liking it alot! While I had everything appart I also replaced the inner and outer tie rods and aligned it myself. I will be getting a professional alignment to check my work, but it seems to be very straight. On a negative note, I found out my thermostat in this engine was sticking open. End result was the car would take FOREVER to warm up the following morning. Idle was higher than normal durning those periods and lean burn was also not possible then. Swaping it helped alot. Looking forward to the next tank!"
2012-10-26 412 9.42 $3.29 43.74 "Wife said we could take my Civic to Chicago on one condition. That I go the speed limit (mostly 70 mph...) I could not get lower RPM lean burn and decided to try a max load/TPS lean burn tank. Speeds stayed between 73 and 80 mph. Engine load was always 88-91 and throttle possition sensore was pegged at 30 (sometimes 32-33 at higher RPMs). Not sure if this is a success story or one of the worst tanks I have ever had since owning the car. Still a good test and the wife was happy."
2012-10-28 578 9.63 $3.05 60.02 "Wife was asleep on the return trip so I could take my time. Lower RPm lean burn worked for a while. Loved the flat highways north of Indy. Wish we had those around Cincinanti."

2012-11-18 525 9.75 $3.29 53.85 "installed new EGR. Fixed the occational check engine light, but not really notice a difference in anything else. Son was sick so I have also been warming up the car in the driveway to heat it up."

2012-12-14 497 9.28 $2.99 53.56 "Had record trip of 67 mpg on this tank. Too bad it was under 30 miles and really does not show in my mpg numbers. Lots of traffic, sick kid so I was heating up the car for him."
2012-12-21 524 9.16 $2.99 57.21 "Using alot of EOC and drafting. Also changed my route a little for better flow in traffic."

2012-12-30 546 9.45 $3.19 57.78 "A few shorter trips, or this would have been a really good tank."
2013-01-06 539 9.02 $3.29 59.76 "Had some really good timing on several trips. Serveral were 63+ mpg trips!"
2013-01-14 527 9.14 $3.79 57.66 "Slightly colder weather. Still alot of EOC and pulse and glide."
2013-01-17 487 8.92 $3.59 54.6 "Testing out OBD1 ECU. Wanted a good baseline for the car going 65 mph without and hypermiling. Only coasting to stops and timing for stoplights."

2013-01-30 528 9.52 $3.59 55.46 "Still testing, but starting to incorperate a little hypermiling back in. As it is I think 1-2 mpg gains are possible with EOC and pulse and glide."
2013-02-07 561 9.16 $3.59 61.24 "Shooting for a record tank, and it looks like a barely got it. It had potential to be 64-65 with several trips higher than that, but in the end I think it was just too cold. Still very good results for the weather."
2013-02-14 534 9.82 $3.59 54.38 "Still alot of EOC and Pulse and glide, but my efforts are a little wasted with warming up the car for my son. Really cold again."
2013-03-01 497 9.04 $3.79 54.98 "This would have been a much better tank, but we had bad weather and slowed down traffic."
2013-03-06 492 8.64 $3.56 56.94 "Had a record trip on this tank. 75.57 mpg over 14 miles! Lots of EOC / lean burn pulse and glide (EOC). Previosuly I think my best for this route was only 67 mpg. Excelent timing with lights, etc."
2013-03-10 394 7.04 $3.55 55.97 "This included a trip to columbus and lots of ""cruise control"" 65 MPH testing. Also installed a kill switch and put my upper grill block back on (more securely than zip ties this time!)"
2013-03-13 497 7.92 $3.48 62.75 "Got a new tune on the ECU. It really improved 5th gear. Also while tuning, we noticed the engine fans kicking on way too much. I guess my central hole for air was not really as good as what I thought and was wasting power/fuel. I made a new lower grill block out of sheet metal and have a slightly larger opening right in front of the radiator. It seems to have helped alot. This was going to be a 65 mpg on this tank, but I hit traffic this morning due to a snow storm. Figures. I should have filled up before I hit the highway! Anyways, I see lots of potential though. I had several 70+ mpg trips and it is definitely capable of effortlessly mid 50’s without any hypermiling. Pretty cool stuff!"
2013-03-20 487 8.04 $3.56 60.57 "Temps got colder again. Really struggled to keep this above 60 mpg. Can easily get mid 50's, but over 60 was rough. Had some bad trips and some unplanned stops in here as well. It is the first day of spring though and I was able to driving in part of the way this morning with my headlights off. Which means, more EOC!"
2013-03-27 506 8.4 $3.49 60.24 "Had some colder weather and some traffic. Asside from that a pretty good tank"
2013-03-28 397 7.02 $3.59 56.55 "Hills going to DC through West Virgina really hurting the gas mileage. Average speed was also 65-70 mph without any pulse and glide. Only EOC down major inclines."
2013-03-28 490 8.96 $3.79 54.69 "Hills going to DC through West Virgina really hurting the gas mileage. Average speed was also 65-70 mph without any pulse and glide. EOC was reduced to coasting with the engine on due to low visability and wanting to use my headlights in the evening. Such a shame as there was a 6 1/2 grade slope for 12 miles. Filled up before getting to DC. Prices were already starting to climb up!"
2013-03-31 502 8.67 $3.79 57.9 "Hills going to DC through West Virgina really hurting the gas mileage. Average speed was also 65-70 mph without any pulse and glide. EOC used as much as possible going down hills while maintaining speeds over 65 mph. When I got back to Cincinnati the gas prices was 3.39.... figures right???"
2013-04-12 607 9.46 $3.339 64.16 "Looks the the warmer temps were helping out! Still a long way to go until they are optimal, but definately progress! Still pretty dark in the mornings and using the headhights and engine on coasting in pulse and glide with the use of headlights."
2013-04-20 604 9.14 $3.29 66.08 "Temps really starting to climb and able to eoc in the morning without headlights on. Also testing out pulse and glide range from 1500 to 2100. Previously was more like 1300 to 1900/2000 and seeing some improvement. Another record tank with room for improvement!"
2013-04-30 686 9.639 $3.489 71.17 "I am a little shocked with this data. I had several trips over 70 - 80 mpg, but the majority of the driving was 66-68 mpg. My MPGuino reset on me 5 times during this tank so the figure was tanken directly from the pump fill gallons to odometer mileage ratio. I am bracing myself for a filling error and lower mpg on the next tank. I did not want to wait another 70 miles to fill up at my normal location, so I filled up at a pump I normally do not frequent.

I had really hoped to get a 70+ tank and have better data to support it, but some things are out of my control.

As for the driving, the weather has been warming up. I have altered the route a little to optimized fuel efficency. It is also getting brighter in the morning so I am EOCing on the way into work now. Even when it is not bright enough, I am just monitoring my voltage and it seems file. Looking forward to the next tank and seeing how much gas it takes to fill at my normal pump."
2013-05-08 627 9.687 $3.51 64.73 "I was somewhat suprised with my last fillup, but it looks like it balanced it out with this one. Also had one bad trip where I was running late and found myself going 75-80 mph and my mpg for that trip was in the low 50's. Hoping for better this tank. As always, lots of pulse and glide and eoc. Kill switch is the best mod ever!"
2013-05-14 597 8.405 $3.419 71.03 "Filled up a little sooner than I wanted, but the gas prices seemed to be jumping up 35 cents across the city. Had a few trips out to my buddies garage with is about 30 miles away, all 50-55 speeds, pretty flat with just enough elevation change for really great pulse and glide. Much needed downtime is near. I ordered some Honda MTF for the trans to see if that makes a difference. As always lots of pulse and glide and EOCing."
2013-05-20 628 9.053 $3.59 69.37 "Had a few drives in the evening where my battery was running a little low and limited my EOC pulse and glide with the headlights on. Still pretty solid though. Lots of pulse and glide and EOC."
2013-05-24 593 8.677 $3.87 68.34 "Had a couple bad trips, but still good results overall. Lots of P&G and EOC. I forgot to check before I reset, but I was close to 50% EOC. mid tank and probably maintained that same rate."
2013-05-31 554 8.601 $3.52 64.41 "Had a few ""rushed"" trips and a trip where the wife was unwilling to take my car unless we went 70 mph with the AC on. Spent the rest of the tank trying to ""fix"" my MPG... lol Still pretty nice to see decent numbers dispite the sub par conditions."
2013-06-05 612 10.173 $3.86 60.16 "Had another series of bad trips. Still managed over 60, but not by much."
2013-06-10 631 9.56 $3.97 66 "Had a nice slow trip to and from Lexition KY. Lots of pulse eand glide and EOC."
