Filling up with my first known ethanol blend fuel today spurred me to check out this thread. I thought I could post my 2005 gas log chart. I only convert from my truck notebook to a chart once a year, so no 2006 data yet.

This is for my 2002 XE 4x4 auto 3.3, stock 30" tires. Pretty stock truck, but I do carry alot of cargo around. Always use 87 octane.

MPG in red, gas prices in blue. The few longer gaps are where I was rotating out my home gas storage, so did not have a good reading.



Not sure what conclusions can be drawn, there's obviously alot of day-to-day variation with driving city vs highway. Reached a nice high in May, believe we had nice weather then so not using heater or A/C. But then dips as summer A/C and possibly summer blend gas. Doesn't go back up in the winter either. Some of this may be that I need a tune-up...
