I can get Kendall GT-1 synthetic 5W-30 for $3.58/qt everyday from one of my wholesale contacts. I've been considering just putting it in as our shop oil. We work on small block Chevrolets, fords, and Chryslers of all ages; big block Chevrolets, Fords and Chryslers of all ages; Ford vulcans, GM3800's, Chrysler V6's, and assorted domestic four cylinders. Occasionally we'll see a Honda, Toyota or Nissan in the shop. I was just wondering what the group thought about using this oil across the board.
