i ran the HP4 for 2 summers, and i drive the Nova almost as much as the daily beater from march-November. oil stayed nice and clean the whole time. then i read that ALL Fram filters are kind of generic, cheap junk, so i now run a Wix filter that cross references over to the Delco PF35, and it is much heavier, which tells me there's more stuff inside, which i would presume to be more filtering media. and it's cheaper, to boot.
you don't plan sincerity.
you have to make it up on the spot.
wanna hear about 20 years ago when i was too smart to know any better?
