Fram filters are crap! Do a Google search on the Web for filter tests. Buy filters from a dealer or Bosch, Mann or other replacement filters.
Overfilling is worse than underfilling. The crankshaft will beat the oil into foam.
Add six quarts after draining than carefully fill to the upper mark on the dip stick. Since various filters have slightly different capacities, it's best to check the level.
You have to order the dip stick seal seperately. I just bought one from an Internet supplier for $.13.
