Been using the B1402 baldwin on my Acuras for ages. However now with miles piling up (250k) and some serious maintenance coming up, i want engine to last as long as possible. I figured the baldwin filters were good since theyre made in usa and seem to get really good reviews, but trying to learn more about micron ratings etc, seeing the baldwin is rated at 23 nominal and 45 absolute, isnt that pretty poor? Or barely decent? Im looking at other alternatives but some are hard to find the micron ratings and efficiency. Any suggestions on a better filter? Looking at premiumguard, Mobil 1,the non-xp wix, k and n, amsoil. Or are some of these overkill? I change oil usually around 5k
