A 260 mile trek, mostly around 60 mph, with a couple of massive downpours of rain and one long curvy driveway I had to back up in the middle of the night...plus a little driving in town and an oil change right at the end. Tires were getting lower so at the end I reinflated them.

Brilliant tank! 200 mile round trip with a tiny bit of EOC, some N coasting, but mostly DWL or CC in flattish areas at 50 mph. 300 mile one way trip with lots of EOC (roughly 25 miles according to how many miles my SG-I didn't count) but also some big hills to climb, as well as DWL or CC in flattish areas at 50 mph.

300 miles of complete freeway driving at around 55 with minimized (but existent) AC usage and some EOC on large hills. Generally, techniques similar to before, with the advantage of the SG. It estimated 5.8 gal used with the 2.0L setting, so I'm going to try 2.4L and see if that yields more accurate results. I really wanted 50 mpg, and I believe the 300 mile freeway portion was, but it doesn't take very much 30 mpg city driving to drop 50 to 49 (actually about 10 miles).

Drove until zero bars were left and chickened out. Apparently there were 1-2 gallons left, however. Standard trip home (55-60, 260 miles), 100 more miles of 55-60, and the rest city driving which was often very bad. First tank with ScanGauge...I tried letting displacement to 2.0L to adjust. I'll get a good read tomorrow on my trip.

240 miles of 65ish highway driving and the rest driving in town, pretty short trips. I tried P&G with EOC during the last 160 miles of highway and it was interesting--probably how the tank was pretty high despite being almost 1/3 city. Good conditions so some but minimal fan/AC usage.

First 240 miles were in zero-degree weather at night, then the rest (return trip) it was nicer weather during the day. A few EOCs on the big hills and to a stop sign I know well, but not very much. 65 or PSL, DWL, neutral down hills, blah blah. A bit too high, a result of the overfill I think happened last tank. Still doing well for conditions.

A standard 260 mile trip home, in colder weather, driving 55 and 65 with DWL and N/ICE-on coast down hills. The rest is driving around town and a little more highway to get to the airport and whatnot. The last 50 miles or so were after the first oil change (w00t!) which was standard issue Honda 5w20...we'll see if the oil change helps in the next road trip (won't be until January) when it will be really cold.

It's a little warmer (40s). I drove 50-60 and tried EOC down big hills. Otherwise similar. Not sure if the increase is all due to EOC of if this was an underfill. I do not think the previous tank was an overfill (it was cold, and 38-39 seems reasonable).

It's getting colder. 90 miles of driving 55 but my tires weren't inflated like I want them, and 260 miles of driving 55-65. I tried some NICE-on pulse and glide on the highway and didn't feel like it helped. I have been shifting at around 2600rpm, but I'm going to try shifting lower and see if that helps. It's getting a lot colder, so I think this will be my last 40mpg tank until Spring.

65 miles around a city then the rest a trip. I drove 55 and coasted down hills and used DWL. Tires up near sidewall. Still original oil E10. 3 adult males and their stuff. Wow. I think the pump last tank filled it more than most pumps I have used, but even then, this is probably more than 45MPG.

About 30 miles of city driving and the rest the drive home from school. I tried driving 55, and I would slow down to about 51 on long hills and try to coast in neutral as much as possible. Sometimes I downshifted and sometimes I didn't...I am not sure which was better. I checked my tires when I got home, and they were about 36PSI, so I'll up them. E10, still original oil. Zero AC usage.

Again almost 100% freeway, this time TO school. My brother thought the last tank had to be the fuel pump shutting off too soon...this proves that wrong and proves a lot of progress! Still E10, same old oil, etc. Lots of DWL and engine-on coasting down hills.

Almost 100% freeway, the reverse trip of the previous tank. A little bit of city driving in there--a few very short trips at the beginning of the tank.

Mostly freeway going from southern to northern Missouri. A little around-town but not much. Tried DWL but had to go a little fast to keep up with the caravan unfortunately.
