I just rebuilt my 22-re and I've been running wal-mart's Super-Tech 10w-30, and putting BG MOA (Motor Oil Additive) in from the get-go. I'm pretty sold on BG, watch these videos. I buy the MOA in bulk on ebay. Just got a pack of 10 for about $5 a can.

I run Factory Toyota filter, although I get the slightly oversized one for the 22-re. I don't have the part number but it's basically the same, with a 3??? on the end instead of a 1??? I think. They can tell you at the dealer.
