I struggled through this winter gas bologna, but now I am still getting the same mileage as I was with winter gas. And last summer the lowest my mileage ever reached was 17mpg for a full tank. My dealer says I should run some engine cleaner or injector cleaner or whatever through it, but I don't buy it. What do you guys think?

5/4/2009 BP 6.634 22357 15.83
5/13/2009 P66 13.257 22577 16.60
5/20/2009 Sams 10.455 22738 15.40
5/26/2009 P66 9.117 22884 16.01
6/6/2009 Sams 12.651 23077 15.26
at the 5/26 fillup I had new tires. Before (with the baldies) I was getting an overreport of about 4% on my mileage, so I expect it to be slightly more accurate now.
I am at a loss.

Brand new coils at the dealer about when I started tracking this btw. I will take it in and change the plugs. Air filter shouldn't be dirty, was a brand new K&N late last fall. I really don't want to try and yank that damn airbox out again. That thing is the biggest PITA ever.
I have read about trying the MAF cleaning routine. I am going to give that a shot probably.
