2016 - 6 cylinder Gas Mileage Dropped?

Hello guys,

I have a 2016 Colorado I purchased in March. It has 8850 miles and runs great.

However, the gas mileage seems to have dropped from an average of 25.5 mpg to 21 mpg.

Nothing has been done to it. I'm getting fuel at the same station and my driving route has not changed.

The only thing I can notice is this when I press the accelerator lightly when starting after a turn or a stop. When I press very lightly to start moving slowly it seems to "sputter" or miss. Like the transmission is trying to find the right gear.

I'm planing on adding a can of seafoam at the next fillup.

Any ideas?
