You got me thinking. I'm not sure there is a long term collection. I have not been through all the buttons yet but I assumed a "reset all" button meant it had that feature, but I have not actually looked for it. (I keep all my tanks on an Excel spreadsheet.)

I do wish there was more than one tracking calculation. I was monitoring the overall tank on the dash on a recent trip and I wanted to calculate the overall trip as well as segments of the trip. I don't think I can do that. The reason I wanted to do that was to measure the trip down I79 and then compare it to the trip back. I got 41.5 going down and 40.1 coming back. By resetting each way it I lost the overall trip.

Oh well probably more information than I really need.
