To me that is Mobil 1 0w40.
Interesting, it has a big fan base here. I don't ever remember reading complaints about Mobil 1 0W40. Occasionally a complaint would pop up about their 5W30, but honestly this is a first for me seeing anyone complain about their 0W40.
Tried it, not a fan. Add me to the list of complainers about shearing.
