Re: Oil Question
I've heard really good things about the Pureolator Gold. And we know that Wix is a good brand (but their economy filter is the NAPA silver series). As for Fram, their $3 filter is, well, a $3 filter. You get what you pay for.
Personally, I've been using their Fram's XG filters (no, I don't get them for free from Fram) and like them (especially after cutting them apart).
Just as an FYI, I interviewed the Chief Engineer at Fram (for my auto articles at The Family Handyman magazine) and he's the one who explained why it doesn't make much difference what size the inlet holes are. Basically you will never need the larger holes in the other brands. The oil pump simply never pumps that much volume. So, I just don't regard the hole size as a factor.
