Jeez, you guys are lucky. With the 4.7 and without the transmission flash to get the extra "gear", I sit around 2100 at 60ish and 2600 at 70.

Well my WK was worse on mileage and my two ZJ's were worse on mileage too. My WK had Quatratrac 1 and the Zj's were full time 4wd if I remember. Zj's had Low as well. No Low on WK. I remember one tank of gas on my lifted ZJ with 31x10's was as low as 230km on one tank. V8 of course. I think it did 15.9 liters per 100km. (14.8 usa mpg) as it's lowest.

Is that what that is because sometimes I feel a little jerk and my instant mpg goes from 13 up to 18-22. And I know I'm already in overdrive.

Sorry - messed up - 87 Octane. We can get 94 octane from Chevron here. All the BMW owners from their club use it.
Long trips I sometimes use 89 but not this time.

87 , 89, 91, 94.

Don't any of your states have VP gas stations with warning signs not to fill up normal cars? Lol. The one up the street from my house in south Florida had 110 octane and C16.
