I will be interested to see if you get a response to those specific questions, and if you do, the answer provided. I read the post and reply in other thread, and I wasn't satisfied either that the response stated 'in the reply itself' that it was specifically referencing the now industry standard for efficiency, ISO 4548-12. I do think it a bit ironic that the email reply took a little shot at Fram for their method of listing efficiency with the ISO test.
As background though, I normally now have avoided any recent discussion of the topic filter. I have done so because of having been one target of a spineless multiple alias troll for previously questioning why no ISO 4548-12 spec is listed on the website or box especially with all the other info listed. The troll went by the names, FetchFar aka, stickybuns, boundarylayer, route66mike, and elastohydro to name some. You will note all those names have now been perma banned, more evidence of the shenanigans that have gone on with the discussion of this filter. The troll's MO was personal attack of any poster that questioned the MG filter and especially the lack of ISO test results. Seemed extremely sensitive to the ISO test considerations, and used the multiple aliases to back itself up using personal attack.
I posted that background information here only as reference just in case history were to repeat itself here in this thread, for this post. Also this is a direct re. reply to kschachn.
As I've said often, I have no problem with whatever filter anyone chooses to use, it's their vehicle and their money. All their website promotion aside, the MG appears to be a solidly made filter. DBMaster having posted often about the MG is passionate about it and afaik never resorted to or encouraged personal attack. He's used it and as far as I can tell trying to follow MG's website suggested use. Also seems to be using it with environmental considerations in mind too. Fwiw, I can respect all of that.
For myself and being promoted as a premium filter, I'd like to see the ISO 4548-12 test results listed with other information, website and/or box. For others, it not being important works for them. But either way, personal attack should not part of the discussion. My .02
