Thanks everyone. I get the TG or Ultra filters cheap on the base I'm stationed at so it doesn't matter which one I buy. Based on the previous UOA done for the '07 Accord is Blackstone recommended me to go 9K miles on each interval and go from there to see if the oil and filter can do more. This is why it would be better to use the Ultra and split the OCIs in half so it'll be roughly two 10K runs on the Ultra. I just had TG laying around and thought I'd give them a shot but even then based on my photos they look pretty good at 12K miles too.
