3). If shock absorbers are past 40k Miles, gas charge has dissipated. Test accuracy should be with new.

4). What tires? Open or closed shoulder? P-metric or LT?

5). What geographical region of USA?

6). Description of use. Commuter? In town only or daily long distance? Are trips under 1-hour in duration, or over 3-hours?

These are basics for a comparison
89k miles

Bridgestone Dueler A/T Revo2 P265-60-18 stock size 40psi hot

so-cal


Engine Hours don't count when in 'Auto Stop' it has been verified not to count it...
88,953 miles
Averaged 65.03MPH with current Hour Count 1367.8 (see how off it is)


mostly City use(40-60MPH speed limits) and 160miles highway once a week..


this is my daily driver....


I try and take the 40-45mph roads because I can Cruse control it 41MPH is the IDEAL sweet spot MPG to SPEED Ratio it's 1 to 1 ratio..

I can't seem to get into Econ mode with Shell fuel aka Active fuel management it just does not make enough power to stay in v4 mode which will GET me the best mpg....


this is a noted issue with Arco as well... No econ mode..


Oil Consumption None 2500 miles into oil change
all using 91 octane fuel (to be fair)
