My other car is a tdi that gets 45-50 mpg. My best is 55 mpg!

I just purchased an 04 z71 suburban. 5.3L v8.

So far it has averaged 16.4 mpg according to the computer. This is completely stock and 35psi in the e range tires city driving.

I'm taking it on a road trip this week and am hoping for 20+ mpg on the highway. I just filled my tires to the max inflation pressure of 65 psi. There was a noticeable visable difference in the shape of the tire with the increased psi.

With 6 or more people in a suburban the amount of fuel consumed is roughly equal to driving the 2 vw jettas needed to haul the same number of passengers. At this moment in history, gasoline is 50 cents cheaper per gallon than diesel fuel.

I'll fuel up before/after the trip so I can calculate mpg the old fashioned way.

Wish me luck!
