Actually, all name brand filters (and most private label) have an anti-drainback valve. It's just a rubber flap.

About 2.5 years ago we held the Texas Oil Filter Massacre at my house and cut about a half dozen new filters apart. The OEM was 2nd best. The Mobil 1 was clearly superior to everything.

Fram sucked.

The rest were pretty much similar.

The filter is unlikely to cause HLVA bleed down.
