2009-06-03	376	8.345	$2.419	45.06	"After this refill I swapped to the VX wheels and 175/70R13 tires. It looks like my speedo has always been off by 6% with the factory 14"" tires (185/65R14). The speedo was reading high so all of my previous tanks including this one should really be adjusted down by 6%. The VX wheels now add another 3.5% change, so tanks in the future are going to need an adjustment somehwere in the 9% range to really be accurate or a 3.5% change to match up with previous measurements. Now I know why people use a GPS to get more accurate mileage info."
2009-06-08	382	8.2	$2.439	46.59	"I decided to only adjust the trip mileage by 3.5% to account for the VX wheels and 175/70R13 tires like the calculator shows me. That will keep my numbers the same as before instead of getting into the issue of the mileage always being off with the stock size tires. So numbers in the future should correlate correctly to my previous fuel logs. This trip mileage was adjusted 3.5% (odometer read 396)"

Calibration is still off a little. The weather was not best for this tank so expect more this summer. Figured MPG the old way, odometer minus 3.5% for vx wheels.
