Do you buy all of your car and or truck service stuff from the local dealer?
I buy Motorcraft filters and SAE oil at Walmart for my Ranger. I took it to the dealer for the 100k tuneup where they used Ford parts because as someone said on the Rangerforums " if they went 100k miles the first time, why replace them with something different?" The service depts of the local "big 3" dealers all are competively priced, and know what they are doing as opposed to some of the hacks I've had do work in the past.
