Chimbu has made a most important point for those wishing to increase the accuracy of their fuel logs............
Use the newer technologies Luke!
On that note, I feel compelled to point people to affording due consideration toward the fuel page in their GPS (eg. In the case of the Bendix/King KLN series, OTH+5), as these GPS thingys are found in even some of the more modestly equipped machine these days. The Shadin air data computer is also something I've often found infinitely more usefull than Mr. Beechcraft's gauges.
So while we may be legally bound to use the manufacturers gauges, I know not of a wise man who chooses not to consider all available sources of information!
