Default Did my engine get ruined?

I have a 1996 Ford Mustang GT that I let a friend borrow, and he drove it about 10 miles with a knock, when I troubleshot it the car had about 1 to 1 1/2 quarts of oil. I changed it and now I hear a good knock around 2500-3000 rpm, but on idle its smooth, and the engine still has good amount of power, engine has about 125,000 miles on it.

Most likely one or more big-end rod bearings have "spun"...

Engineering is, at its base, making what you want from what you have.
At its extreme it is making what you want from what you can get.

Not good you need to check the oil level on a regular basis, but now the damage is done.

"Spun bearing" does not mean "new engine" until such time as the rod(s) let go and come through the block.

It does mean pulling the engine, then the oil pan and seeing what things look like in there...

I'd fix it. Having a rod come through the block on the road can be a VERY bad thing, for you and other driver's.
