2016-06-18 677.8 9.461 $2.429 71.64 "The first tank. All the things wrong with this tank...
-Learning to drive the car (never Honda/Lean Burned before)
-Teaching wife how to drive a stick (1st gear go/stop hell!)
-Had to bleed coolant system (idle for 20-30 minutes!)

Otherwise, grid charge when battery low (about every 3-4 days), grid charge 12v when possible, block heating about 1/2 way through, WAI towards the end, Aero modding throughout tank (fixing panels, removed wipers, removed passenger mirror), experimented with tire pressure (55/60 seems to be good to go!) and various weight reduction."
2016-08-16 802.7 9.586 $2.389 83.74 "Various things added throughout this tank, such as the underbelly panels and kill switch. Tank metered at 88.8MPG, but had the 150MPG glitch for a few miles."
2016-10-10 740.2 9.565 $2.289 77.39 "first ~300 miles at around 91.8MPG, then another 300 miles going up into the mountains at only around 66mpg. Otherwise, no real mods done on this tank."
2016-11-03 665.4 8.384 $2.289 79.37 "There were some miles put down on gravel roads (for hiking) but mostly normal miles otherwise.

trip gauge reported 80.1MPG (62.2 life)"
2016-11-07 789.5 9.654 $2.289 81.78 "First full road trip! Did a little more grill block for cooler weather for the trip. Got me to my destination and back, no problems. Averaged probably 50MPH, headwinds on the way back. Metered in at 81.5 total MPG on the dash, 62.2 life. Tires at 55/60 F/R"
2017-04-13 752.8 9.857 $2.389 76.37 "Mixed winter driving, even tire cable usage! 50/60 tire psi. Just about 100% city driving."
2017-07-16 835 10.129 $2.459 82.44 "Pretty much all city and doing all the usual stuff!"
2017-08-24 303.7 3.589 $2.699 84.62 "Fillup before long trip. All city miles. Warm! So that helps a lot. Did some aeromodding right at the end of tank (full pass mirror delete, drivers mirror micro swap, remove antenna and washers, new lower grill block, and extended rear belly pan). Life of 62.5mpg and tank claims 93.2 on tank."
2017-08-28 690.2 8.484 $2.199 81.35 "Road trip! Kept the car as fast as it would go in Leanburn pretty much the entire time. Some 10% grade climbing was rough! Had to 1st gear high RPM to get up it, sadly. Probably averaged 50-52mph if I had to guess total. Gauged at 79.6mpg for the tank and 62.7 life."
2017-08-28 706.7 8.549 $2.699 82.66 "Return trip. Same deal, all highway and pushing leanburn as often as possible to the limits. 55/60 psi front/rear. Going back up 10% grade was brutal, again. Had a section where had to force 70mph due to 1-lane and traffic requirements for a good 10-20 miles."
2017-11-01 757.2 9.292 $2.539 81.49 "Temps have dropped quite a bit, so no surprise that MPG has as well. MPG for tank is reported at 84.1 with lifetime of 62.7."
2017-11-05 681.7 10.48 $2.859 65.05 "Road trip, plenty of cold, uphill, in the rain, headwinds... you name it! Was a rough ride for MPG, that's for sure."
2018-01-26 728 9.434 $2.499 77.17 "Return trip of nearly 400 miles highway. IMA boost disabled the last 200-300 miles of this tank. 73.5 reported by computer on tank, 62.9 lifetime. About to the 10K mark for me with this car, finally!"
2018-05-24 690 9.647 $3.289 71.52 "From winter till now. IMA no longer used to boost (via relay), but only regen braking. This tank was filled with ethanol free fuel."
2018-08-17 738.6 9.74 $3.499 75.83 "This tank was on 87oct ethanol free fuel. IMA failed on this, various phases of taking it out throughout tank. Almost 100% city driving here. Meter said 79.9mpg."
2018-10-26 920.1 13.113 $3.408 70.17 "Pulled the IMA battery. Experimented with drive styles. Right at end of tank, got leanburn working again. First 400 miles was doing 70mph on the freeway w/o leanburn, with some AC! Rest should be city.

Did 2 small purchases and one full fill of 2.206, 2.025, and 8.882 gallons (keep the weight down for city driving, filled for upcoming road trip). Gauge said tank should be 71.4MPG."
2018-11-06 779.5 9.678 $3.419 80.54 "All highway trip, doing 55-60 mostly (keeping on the edge of lean burn). Ethanol free fuel. gauge said 83.8, but it is often lower than that."
2019-02-19 922.2 14.331 $35.92 64.35 "I did a $10 partial fuel fill on this tank, then a full fill, so I didn't actually go 922 miles on this tank (648.9 miles did 3.877 gallons of ethanol free with a reading of 69.0mpg at that point, then 10.454 gallons to another 273.3 miles)

Front grill block pretty much everywhere. Just ran the heater if I went 10+ miles and the coolant started to get warm. Winter sucks for MPG as always. Tried to keep 50/60 psi front/rear, but haven't checked nearly as often as I should.

Again, all ICE as the IMA system is dead and gone, torn out, never coming back."
2019-03-25 799.2 10.176 $2.779 78.54 "filled with 87 octane E10. Probably 60-70% highway. Mostly cold still, but starting to warm up. Car claimed 78.4mpg tank and 63.4mpg life."
2019-04-11 705.5 10.102 $2.859 69.84 "Return trip, did not hypermile super well because too tired, so probably 60mph average or more? Probably 70/30 highway/city. Tank was on E10, filled with E0 again, as E10 seems to definitely put a dent in the MPG. Booo corn industry."
2019-05-30 773.5 9.508 $3.499 81.35 "Wacky weather throughout this tank, from cold and wet to warmish and sunny-ish. RE92's put on just over half way through this tank, immediately aired up to 50psi front and 52-53psi rear. If I had to guess, about 50/50 highway to city. Most highway 50-60mph.

Tank readout before RE92's was like 74mpg, ended at 81.0 for the car life (with 196,007) at 63.4"
2019-06-16 880 9.958 $3.129 88.37 "150 miles mostly city driving, rest a long trip doing 55-60mph average, going up 3,000 feet at final destination. Intake air changer melted about 200 miles in, causing some intake restriction but didnt seem bad. Tank reported 91.1mpg and lifetime 63.6. Tires 50/55 front/rear."
2019-07-01 916.3 9.535 $3.299 96.1 "Return trip from 730 miles all interstate, plus another 100 miles interstate, so very much mostly highway. Going 55-60mph most of the time, keeping in lean burn as much as possible. 50-54psi front rear tires, coming off of 88oct eth free fuel. Filled with 87 eth free. Gauge said tank was 95.6 and life is 63.6."
2019-09-27 783.4 9.662 $2.999 81.08 "Mostly city driving throughout summer. One trip up into the mountains that hurt the ol MPG, but overall, still good."
2019-10-30 423.1 6.278 $3.239 67.39 "Charging the lithium 15.5v battery w/ secondary meanwell hurt! Plus it's getting very cold. Otherwise, same ol E0 fuel and daily driving."
2019-11-03 789.9 9.78 $2.99 80.77 "Road trip up through the passes and climbed ~2,000' up in the end. 50/60 psi tires, keeping 50-60mph usually (whatever leanburn would allow at the time)."
2019-11-09 863.9 9.952 $3.269 86.81 "Long road trip back. Kept in lean burn as often as I could. Dropped elevation ~3000 ft. E0 gas of course. Over 200K and overall car is at 63.9, tank supposedly 86.2."
2019-12-23 695.6 9.784 $3.039 71.1 "Winter driving conditions, lots of cold mornings especially. gauge says 73.7mpg tank, 64.1 life."
2020-01-19 720.6 9.591 $2.839 75.13 "Still winter. Haven't bothered checking tire pressure or going out of my way for best MPG, but still doing a decent job hypermiling. Tank metered at 76.6 and life at 64.1"
2020-02-13 740.8 9.682 $2.769 76.51 "Quite a bit of highway plus a warm winter. I assume my tires are still full of air. Tank said 78.0mpg and lifetime of 64.1mpg."
2020-03-06 761.3 10.011 $2.87 76.05 "Quite a bit of highway. Saw 90+ a few times during warmer weather, so we're almost out of the winter MPG dystopian era. Keeping tires around 50+ front and 58ish rears. Often pushing to the limits of leanburn, which is usually between 55-65 MPH. Tank MPG reported as 77.5, lifetime at 64.1"
2020-03-30 783.6 9.736 $2.599 80.48 "Mostly highway, some days warm and some days, not so much. Kept on edge of lean burn most of the time (50-65MPH, depending on hill grade). Gage reported 83.1mpg tank and 64.3mpg life."
2020-04-19 813.5 9.829 $2.039 82.77 "Mostly highway, doing 60mph likely on average (as low as 50mph up hill, 65+ downhill, 60-65 on flats usually) and the temps are getting warm! (spring)

Likely, 55-60psi all tires (higher in the rear likely). Yeah, I'm really keeping an eye on the basics... lol

84.1mpg tank and 64.3mpg life according to the car's computer."
2020-05-25 734.8 9.401 $2.139 78.16 "A lot of idling and highway... a few short trips here and there. So yeah, doubt this is gonna get me an 80. said 78.2mpg and lifetime of 64.3."
2020-06-04 584.3 7.623 $2.479 76.65 "Mostly highway road tripping into the mountains. Keeping on edge of leanburn, but plenty of WOT up the inclines to keep a ~50mph minimum. Average speed around 60mph. Tires 55/60psi front/rear. Last tank was E10, filled with E0 this time."
2020-06-08 835.8 10.242 $2.539 81.61 "Through the mountains and into headwinds about half, just mountains the other half. Edge of leanburn most of the time, but the headwinds and hill climbs were pretty low geared and full throttled! This had about 50/50 E0 and E10, so like an E5 tank. Filled with 87E0 this time."
2020-06-23 778.8 9.463 $2.599 82.3 "Filled with E087, reported 81.0 tank and 64.6 life (208K miles). Just standard driving, highway mostly. Lean burn as often as possible, usually pushed to the edge for 55-65mph."
2020-07-31 773.7 9.688 $2.599 79.86 "Driving everywhere, mixed speeds and such. Plenty of AC usage (for me, lol. Mostly downhill and when coming to stops, but even on the highway at times). E087 yet again. Reported 80.6/64.6 tank/lifetime MPG."
2020-08-27 810.3 10.223 $2.679 79.26 "Plenty of running around in the heat, usually only using AC when coming to a stop (in gear, to slow car, mostly stop lights and such). Haven't checked tire pressure, any highway is pushing leanburn to the limit typically. Reported 84.6/64.8 tank/lifetime"
2020-10-15 724.9 9.714 $2.619 74.62 "Filled with E0-87. Lots of AC usage in August and some in September. Had a tire go flat and all tires were set to ~32psi from the tire shop, which was maybe 100 miles of tops. Set to 44psi at the end of tank. Definitely didn't give it my all this tank for best MPG. Tank reported 74.2 and life of 64.8"
2021-02-18 625.4 9.643 $2.759 64.86 "Cold weather, low tires and definitely not doing much to hypermile. Maybe next tank."
2021-03-26 676.5 9.13 $3.359 74.1 "Starting to warm up. Several highway adventures, but mostly at higher speeds (less lean burn). Tires put to 42psi, since the tire guys suspect me... as always, E087, tank reports 74.0 and lifetime at 64.8."
2021-05-10 625.2 8.578 $3.599 72.88 "Some highway, some city. Filled up early before prices skyrocket at the pumps! Been keeping my tires around 40-44psi."
2021-07-07 753.5 9.894 $3.879 76.16 "Mostly highway, kept in leanburn as often as I could. AC usage was often, since we're hitting 100+ every day lately (boo). Filled with E0 as usual."
2021-11-19 624.5 9.838 $4.039 63.48 "Tire pressure was a bit low, it's cold, it's almost all city... so probably my worst tank to date! Oh well. Still beats (insert car name here)."
2022-02-21 599 9.705 $3.859 61.72 "Cold weather, Almost all city short trips! Definitely not going to be the most impressive tank I've had..."
2022-05-17 646.8 9.55 $4.719 67.73 "Almost entirely city and plenty of cold mornings and days. Just starting to warm up, so I bet the next tank is good..."
2022-07-29 645.3 9.309 69.32 "Super hot weather end of tank, not running AC pretty much at all, nearly entirely all city driving."
