I've been using Mobil 1 synth 5W-30 (or 5W-20) with an oversize Pure One PL30001 filter on my 99 2.7. If I cant get ahold of a Pure One, I'll get a Napa Gold or Wix.
(To use the oversize filter on the 2.7, there is a small boss that hangs down off the filter mounting that needs to be cut off/ground down flush with the mounting surface, to allow for the larger filter diameter. I imagine if you ever need warranty work done on your motor, and Toyota tells you its due to oiling issues, I'm thinking if they see the boss removed or an oversize filter, they may not warranty it...Just something to think about before making the modification)
I've always wanted to cut open one of my used filters to take a peek inside, but havent gotten around tuit yet....
I usually go about 6.5K to 7.5K on one oil change....
I've always wanted to send in an oil sample for analysis (even collected a couple samples), but havent gotten around to that either...
