'If' my local WM is also an indicator, then it would seem the HM filter is quietly being removed from the Fram line. At the very least it would seem it is being removed from WM store sale. They are clearance priced here at $5 each, which imo is still too much. Anything more than the price of an equivalent orange can is too much, because other than the gel basket that's what the HM is. In one anecdote posted here not too long ago the gel didn't dissolve over the oci.
Marketing aside, imo the 5k mile HM is a pointless filter. Most any filter and API rated oil is good for 5k miles with no worries about TAN, which is the advertised point of the proprietary additive basket. No reason to pay the HM price premium over the orange can if that is one's filter of choice for ~5k miles.
Here the Mobil One oil filter line has been given the new available shelf space, priced at ~$10. And looking closely at several, they are all still Champ Labs made. Based on their box efficiency appears Super Tech not the only filter using an other than a 20um rated efficiency level.
Also not surprised at all BD+ filter is being closed out at WM. Said previously I would be surprised if they were sold much longer. Though a good filter ime, overpriced for what they are. They have become obsolete with better options like FU available for less.
