Last Saturday, I changed the oil on the DCT for the first time at 3,950 miles. New oil and clutch filters + five quarts of 10W-30. I am mechanically challenged but I can follow directions on simple maintenance procedures detailed in the service manual. Everything went well except for one thing: Only four quarts of oil came out of the bike. Grr! I guess I have no one to blame, but myself. I should have checked the oil and other fluids when I got it home from the dealer.
