The invention discloses a damping fixing support of an automobile oil pipe. The damping fixing support comprises a rectangular bottom board. Vertically-upward sleeves are formed on the two sides of the bottom board. Insertion holes are formed in the top end faces of the sleeves. An M-shaped supporting board protruding upwards is stamped on the portion, between the sleeves, on the bottom board. A strip-shaped press board is arranged on the upper side of the M-shaped supporting board. The two ends of the press board abut against the top end faces of the sleeves, and bolts are inserted in the twoends of the press board. The bolts penetrate through the insertion holes of the sleeves and are sleeved with damping springs. The upper ends of the damping springs abut against the inner side bottomfaces of the upper ends of the sleeves. A rubber gasket is pasted and fixed to the periphery of the lower end face of the bottom board. A rubber buffer mat is pasted and fixed to the lower end face, over the M-shaped supporting board, of the press board. The damping fixing support is simple in structure and can damp vibration of the oil pipe, reduce noise and avoid an oil leakage phenomenon; and meanwhile, main parts of the damping fixing support are stamped parts and are convenient to manufacture, auxiliary parts are standard parts, the production efficiency of the support is high, and the oil pipe is convenient to install.
