The Fram HM5 (long chevy 350) are on "clearance" at the local walmart for $5.... sheesh!
...on the same shelf is (a LOT) of the HM9100 (Chevy DuraMax) for $2.50...?
Since it's the same thread/gasket, I grab a couple of the HM9100 & head to check out... they ring up as $1.00 each!
I was riding the Softail, so I didn't get more. I guess I'll head back (when I pick up my Penzz PUP) and grab another half dozen or so.
I don't care about the silly goop cartridge inside, as long as they still filter.
