K & N filter change
I purchased a 2013 GMC 3500 with a duramax diesel engine.....I filled it up, took it on a road trip down the interstate 65 miles to the next town then turned around came back and refilled it. 17.3 mp...

Totally agree.
When I was younger, I "had to have" a K&N on every vehicle (on- and off-road) I owned.
Then I started to look at the intake tract downstream of the filter...dirty/dusty every single time.
I run OEM filters of my truck now, and every time I look at the intake tract downstream of the filter...perfectly clean.
For my off-road toys, I went with oiled foam filters...and my intake tracts stayed clean
I never blew a motor or anything using a K&N, but dirt getting past the filter isn't good.
IMHO the dirt/dust was probably a function of not oiling the filter perfectly. But I'm the idiot who needs to buy idiot-proof things.
