Proselects are good filters, less media than golds, even less media than Ecores. But for 5k I think they are fine, careful, some are made in Mexico, the one for my riding mower was made in mexico. I have two sitting in the garage waiting for my 4.3 truck, half the size of a pf52, but ok for 5k miles, use without hesitation.
My local NAPA has 5 quarts of NAPA conventional and a proselect for 12.99 manager special. Good price.
