As I mentioned in a post from another thread ( HERE ), I contacted Highline Warren a few days ago to see what they say now about the efficiency spec on the new Mobil 1 oil filter. When I called well over a month ago, I was told it was 99% @ 20u, but when I called a few days ago and the question was escalated higher I got the info below.
So I got a response today from Quality Support at Service Champ. Strange that Service Champ is involved, but maybe Highline Warren also handles Service Champ, which we have seen to be tied to Premium Guard Inc. (confused yet, lol). Is the new Mobil filter a Service Champ in a Mobil can? See the email snap-shots below.
So it looks like the efficiency of 99% @30u and greater particles is what the new Mobil 1 filters are. Also, I was at Walmart a few days ago and saw both filter box styles - one with the old M+H filter & one with the new Mobil 1 filter. Both had the statement "Efficiency rating based on removing particles greater than 30 microns" on the box. See photos below I took at Walmart for both the old and new boxes.
