So at the height of my 'modding" winter gas shut me down. 23-24mpgs were the norm. on level roads.

Today I was driving back from Walnut Creek Ca to Sacramento CA - about 60 miles- and said to myself "hey why don't you slow down to 63pmh and check the Scangauge?" (I know, can you believe I actually said "63mph"??? )

I saw that the SG's mph were off about 4% compared to my Garmin GPS so I went into setup and adjusted the mph to match the Garmin.
I also cleared my onboard mpg gauge.

I know thay my car mph is off about 3.4% because I run 255/45/18 tires instead of factory 245/4518.

*******NON-SCIENTIFIC RESULTS ABOUT TO BE POSTED********
THe scangauge reported 29.3avg mpg while the car reported 26.4 avg mpg.

THose were the best avgs over the last 4 months.
So before I get toooo excited ......
does anyone know if the gasoline blend has changed back??
