Extended length oil filters
Cornholio,
Good catch! When I looked at the specs, I didn't even notice the micron rating. Interesting that they would have two filters on their assembly line, and to have a different micron (size) filter rating. Would this mean they are using a different paper medium? Why not use the finer filtering paper on both filters? And, the two quart filter is only 2 inches longer than the 5-inch filter. That volume of a cylinder math problem is incorrect. Things that make you go Hummm!
