I'm going to give the boss a try. Been running the amsoil filters since I bought my sho. Great filtration, but rattles often at a cold startup with 5w30 (with 5w20, cold start rattle is very rare). I like the Pure Boss filters. I Run them on other vehicles. Gonna swap my amsoil filter for 1 this weekend to try. I'm only 2k into the oil change. The rattle was just something I grew to expect.SHOdded said:The specs look great on paper, but the fact remains, based on my own testing on the Edge, only the Motorcraft filter has never caused a startup rattle. There is no doubt the extended life filters have a lot going for them, but I would rather have to change a MC filter twice during an extended OCI than go with another brand even though I very much want to.
Tested: motorcraft, k&n, mobil1 ep, amsoil. Have not tested rp yet, on my list. Also on my list is aFe, since they have a larger capacity version of the filter for my Edge.
Never had a startup rattle till i tried a non-motorcraft filter. Even the new Purolator Boss may not be immune.
