@ Merkava...no , not all. It runs the entire range of dino , syn blend, full syn...I have jumped around a lot. If full syn, usually 10k OCI, blend is 7500k OCI (usually by oil monitor) and dino is 5k OCI. U name a brand name available at Wally world or Auto Zone..I have probably used it. Currently has VWB 5w20...with a quart of Synpower 0w20 leftover from the wife's car's last change to make up the last little bit.
