When should I change my air filter in my truck? I got like 28k on it right now... but I was reading the Scheduled Service Guide, and it said at 30k to check it. I checked it the other day, and it was just a little dirty... but my Filter Minder hasn't moved since the winter time because it would get clogged with snow, but now with summer, it hasn't moved.
I might wait until 40k.
