Different refiners will make a difference in your mileage, especially if you use cheap fuel and then put in a major brand. Go to same pump at same dealer and fill to the brim, then check it.
Had a K&N on my truck when I bought it used. (7.3 Diesel) Ran my finger down the air intake hose and could feel the grit. Immediately changed the whole filter assembly, to the optional super filter Ford makes, and now it's clean with no grit when I check it. The Chevy board did the K&N test on a flow bench and the results were very conclusive in my opinion. Mileage didn't change. Will never run K&N stuff ever again. .
Good luck, safe travels and happy camping!
