New problem, video up. need help...again Options

[Malhar95]

So I was driving and my oil light started blinking, few minutes later, I started hearing this weird grinding/knocking sound at high rpms so I slowed down to around 50
Then I put the car In nuetral and reved up, sane sound
I lost some power and the the car shut off,
I thought I ran out of gas so I filled few gallons in (I luckily stoped in front of a shell)
Started it up and hears LOUD squeaking along with the knock,

Checked my oils and i was OUT/EMPTY

So I put in 4 quarts of "golden state sae 30" (that's all they had)
Drove it to my work and now my car stopped squeaking but still hear a knock!
The oil is 'dirty but full' ....

What could it be?
No oil leaking from the bottoms, muffler is dry nothing out of the ordinary beside the knock

Keep in mind that I rebuild the engine 5000 miles ago so could it be that I messed up somewhere?
And after the rebuild, I didn't change the oil until 1300 miles like the Haynes manuel said
