Is 3-1/2 quarts enough for oil change? My 05 glide takes 4 quarts exactly. I suggest a long interstate ride. Long consistent heat is good for the whole motor including rings and seals. I suggest several hundred miles in a day. Engines clearances are engineered to run at the operating temperature for proper thermal expansion. I have stopped new oil usage in cars and trucks with a long hard trip more than once. Good luck.
