I'm not too far off from being able to re-fill tank at will instead of partial fills. Might spring for a winter cover depending on commute. TX_dj has me sold on an Ultragauge. Ever since you've started the Team Cummins group I've dialled back on shift rpm (DD is never over 1600, I tell myself) and gotten used to catching the next gear by 1,100 instead of 1,300. The overhead tells me I'm better, but . . . .

Thanks, slowmover! As far as when it will come back up, the 29.9 mpg was just a one day thing. I'm still averageing about 34ish on the lie-o-meter (averaging good days, bad days, mornings, evenings, etc). Back when it was warmer I was averaging up closer to 36-37 or so. In the last month or so the temps have averaged in the low 30's--that doesn't help. A couple days ago, it warmed up a little for about 2 days (temps in the 50's). Sure enough, for those 2 days I got quite a bit better FE.

I get my temperature data from a local weather station on the Weather Underground site (it really is a weather site--not the 1960's terrorist group ), They have stations all over the US and you can look up historical weather for any day you want (temperature, pressure, humidity, wind speed & direction, precipitation). I've kept a record of every commute since April in a spreadsheet with the weather data, as well as comments on changes I made, mods, route changes, etc. If you're interested PM me your email address and I'll send you the Excel file.

Didn't know you got the Ultragauge from TX_Dj. I knew he was having some trouble with it. I guess he gave up(?) I need to get one but haven't yet. Maybe here soon.

As far as the shifting goes, I guess you'll just have to wait until you get to the pump to find out for sure. I've learned shifting is kind of a habit thing--once you've done it one way for a while it takes some concentration do adjust your normal routine. Let me know how it turns out.

Edit: Just re-read your post and saw TX_Dj sold you on an UltraGauge, not sold you an UG,
