For awhile I've been noting that we keep a fuel log because our fuel gage doesn't work, but our engine hour meter certainly does.
This is a page of our fuel log. It's on a spreadsheet, so all we do is enter the date, the engine hours, the fill amount in gallons and the cost, and the spreadsheet does the work. If you look at the columns, you'll see it's pretty easy to figure out how to set it up. As I suggested in a recent post (see: http://c34.org/bbs/index.php?topic=3824.0
) you don't have to do this as conscientiously as we do, just try it for a few fill-ups and you'll know how much fuel your engine uses.To see it, right click on the attachment filename below, click on "Open in new window", click on Open (or save, your choice).
