In this present article, we study different accretion properties regardingviscous accretion of dark energy. Modified Chaplygin gas is chosen as the darkenergy candidate. Viscosity is encountered with the help of Shakura-Sunyaevviscosity parameter. We study sonic speed vs radial distance curves. We comparebetween adiabatic and dark energy dominated cases and follow that sonic speedfalls as we go nearer to the central gravitating object. As viscosity isimposed, a threshold drop in accretion sonic speed is followed. Average rate offall in accretion sonic speed is increased with black hole's spin. This issignifying that this kind of accretion is weakening the overall matter/energyinfall. Specific angular momentum to Keplerian angular momentum ratio is foundto fall as we go far from the black hole. Accretion Mach number turns high aswe go towards the inner region and high wind Mach number is not allowed as weare going out. Combining, we conclude that the system weakens the feedingprocess of accretion.
