I ran oil dry after a leaking oil filter spilled it all on the road for 2 minutes

So I changed my oil today and for whatever reason did not lube the gasket cap on the new oil filter before putting it on. Also, I cranked it an extra 1/4 turn with a oil filter wrench. Got in a hurry to meet friends of wife and did not test run the engine. Get to place fine. As soon as I crank up the engine to head home I hear slight knocking in the engine. Ran maybe 1/2 to 1 mile and knock worsened then my engine shut off. At this point I lost power steering and luckily happened to be in front of the auto parts store. I put 5 quarts + 1 quart of lucas in it after changing oil filter. (filter appeared fine but the gasket was a little loose). I then cranked it up and heard the knocking again for about 4 seconds before it went away. I drove home and everything appeared to be okay. Guy at the autoparts store said I was incredibly lucky. My question is do I continue to run 5-20 in the 4.6 V8 or do I now have to add lucas everychange or switch to heavier weight?
