I purchaced 9 qts of Quaker State Torque Power from W*M on closeout in early spring 09 and am about to use it on the next OCI. Of the 9 qts, 3 are 5W30 and the other 6 are 10W30. Has anyone had any experience with Quaker State Torque Power and would you like to comment. NOT Quaker State Q Horsepower but Quaker State Torque Power! Looking forward to hearing your reviews and please mention your vehicle, engine and OCI/mileage
