I just run the honda oem and swap only filters and top off at 50percent oil life. Napa Gold are great filters and i still like the fram ultra filter and Mobil 1 filters.
No...just the oem filters and now Pennzoil Ultra Platinum 0w20. I get them for employee cost and they swap out at no charge every 5k miles. I know there are better filters but its convenient to do as I do and I am not making enough extra power to worry too much yet.
