When our CTD was at the dealer getting the oil changed (because I haven't decided on which full-synthetic to use, and it was also a time crunch - and its $40 for Dexos2) and having the latest recall fix performed, they also called me to tell me about the air filter and that is was "Dirty. Like, really dirty". They understood me not wanting to pay them to install a new one, but I also thought they might just be over-exaggerating - especially since the car is just over 50k miles.
Sunday night I popped the hood, and removed the 35,000 screws that hold the airbox together, and lo and behold, the air filter is pretty **** dirty. Not the paper, but the "foam" on the bottom, is practically black. So they weren't lying, or talking it up to get another sale (good points for our service dealer, which we've been happy with thus far), but it definitely surprised me with how dirty it was for the mileage. I'm used to replacing filters at far longer intervals and still not having them be that dirty.
Must be the foam catching smaller particles first (along with bigger ones)? Anybody else notice the same?
Ordered a new Delco filter yesterday, should be here Friday. Maybe we'll even see a small increase in fuel economy if all that dirt in the foam is causing a decrease in breathing ability.
