Check for damaged pistons, rings and gaskets by pressure testing the cylinders first. Might even be a blocked breather pipe, who knows until you look.

Does not sound right, the engine oil capacity for your engine is 5.7 liters with the oil filter. To add 5 quarts, your would have been running with no oil for who knows how long. As for your engine running the way it is, with no engine oil means a complete over hall. The ruff idle is caused by worn cam shaft and the crank shaft bearing must be worn to, and the possibility of spinning a bearing is high. Sorry for the bad news but with the information you gave me, this is the what i can come up with.
Good luck and hope there is a better out come.
