First time posting, and as I've come to realize, I'm actually quite a noob when it comes to my knowledge of oil, and oil filters, so be gentle with me! I'm about to change the oil on my 2018 Honda Accord 2.0 Sport. I know the A01 (Filtech) filter has been discontinued, but conventional wisdom was that it was better than the A02 (Honeywell), though digging around on this site, I see that might not actually be the case. I ended up ordering a pack of 5 A01's from an Amazon seller. After I got them, something just seemed "off" to me about the way the filters looked, particularly the white lettering printed on the filter itself. It just seemed rather "blurry." Before jumping to conclusions, my first step was to get online and see if I could find an actual Honda Dealership that was still selling A01's and order a couple. After they came in, I would compare to the filters I got off Amazon, and see what was up. Well, the dealership sent me a box of 15400-RTA-003 filters instead. Emailed the dealership, they assured me it was a mistake, and told me to send the 003's back, and they would ship out the A01's. I sent the package back, and now about a week later I got my replacement order......a box with 5 of the same 003 oil filters in it! *face palm* BUT ANYWAY...Since my original plan of getting a few A01's from a dealership to compare my Amazon filters to, I'm here looking for help... 1. I had previously read that there were a few things to look for on A01 filters... - PLM printed on the top of the filter - the diamond stamped on the bottom of the filter - obviously the Filtech logo printed on the filter So I decided to snap some pics to post here, and I noticed some even more odd things about the filters while I was snapping the pics. first and foremost, the bag they were shipped in secondly, the 5 filters, sealed, with their Honda part sticker...so far so good looking... third, they all have PLM on top of the filter, Filtech, sticker, same batch number "8A15" maybe(?), etc...the pictures don't seem to do the "blurry" lettering justice next, is where I found things got interesting...the diamond stamp...they don't match. I've read it is supposed to be a diamond with dots. two totally different looking stamps...one has dots, the other doesn't. The one without the dots, is also not stamped straight, while the one with dots is lined up straight with the holes... In the package, I got 2 filters with the diamond + dots...and 3 filters have the crooked diamond with no dots...are these normal production variations on the filters? Or is something wrong here? Am I paranoid, or did I actually get some counterfeit Honda filters? last thing...from what I've been able to gather, the 15400-RTA-003 is an equal part to the A01, meaning, if my car uses the A01, the 003 should also fit. Is that correct? If so, is it a decent filter to use? I'm going to be using Amsoil Signature Series oil during the oil change, is there a better filter to use than the OEM Honda filter? I'm not really concerned with how much the filter costs, because I don't put many miles on my car, and I'll only be changing the oil once or twice a year. Thanks in advance a whole bunch for your help!
