The Caravan (Viper) filter just increases the total oil system capacity like adding a deep sump or larger oil pan. It is only a half a quart but it is a free 1/2 quart so why not. For a NAPA # you can cross the FL300 from Motorcraft.
The advantage is just more oil which you end up buying anyway, you know that last 1/2 quart. You just dump the whole 5 Qts. in. The filter costs the same the oil is already bought and it still sits well above the sub-frame so why not.
