You have to let the computer work but you only have 300+ miles is not enough.
Look this picks just from Brick NJ to Williamsburg VA 2 weeks ago.

Yes I been using premium on my first fill up now

We have 50k miles on my wifes denali and its never had a tank of premium in it. Always up around 19-20 mpg and runs great.

Im not trying to change anybodys mind about running premium, but I know we sure as heck are not gonna start now. I see no reason to. Would it run better? Maybe. I dono. But it sure seems to run great without it.

Sure he may have a performance suv.. but regardless, his average mpg’s is less than half what it should be. Something is wrong.

Sounds to me like the biggest problems are his planning and thinking. I wouldn't buy a Prius and then wonder why I can't comfortably haul my nine kids around.

Im near close to 500 miles almost. And still disappointed almost 9 mpgs this really is weird. I read here I the forum as many have gotten great mpgs right from the start in the city . Other tell me no where near mine 9 is too low . And the dealer just says it still not broken in lol. Today I defiantly wanna break it in with a sledge hammer hit the engine till it really breaks lol. I’m bummed out today.

Jorge, if you are driving around in the city, stopping every 1/4 mile for a light or stop sign, the mileage is going to be like that. Make some time, fill up the tank, and go have lunch at Dixie Crossroads in Titusville and see how she does out on the road.

Are you resetting the comp everytime you fill up?
