I'm going to try the "every other oil change" for my filter as Honda now recommends this on some of its models (up to 20,000 total miles on the filter)and there have been numerous posts here about filters going 10-15,000 miles being cut open and looking fine. My question is are WIX/NAPA GOLD filters a good choice for 10,000-12,000 mile change intervals? (I'll be changing the oil at 5,000-6,000 mile intervals and the filter every other time) Pete C.--what do you think? Are Wix filters tested for this duration? Thanks!
