MC, 3B, & 7A oil filters

[Rick Houck]

Brett,

So you think I could choose the one for the 3B (presumably the most 
demanding application) and use it safely on both of the others? I go through 
8-10 per summer driving season, and the Mahle, Mann, and Bosch all seem to 
be $4 something, which I think is reasonable.
