Just read that a single grain of sand can wreck a diesel injector

Found this in a tech bulletin from a heavy equipment dealer. They said a particle as small as 5 microns can mess up the spray pattern. That's way smaller than a human hair. I've seen injectors fail and blamed fuel quality, but never thought about the air intake side that much. Makes you double check every filter change. Anyone else run into weird failures traced back to something tiny like that?

Heard the same thing from a mechanic last week.

Yeah but @hayden_rivera, what if the mechanic just had a bad day?

Sounds like a pretty weak excuse.
