I don't remember seeing it on the shelves at Pep Boys. Where can I get some Amsoil? Oh yea...I should have read up before I changed my oil last time...I used a Fram filter (the premium one in the sealed up container...the L16440 is ALWAYS ALWAYS ALWAYS sold out) and the "new" Mobil 1. I am pretty much anti this new formula. I searched everywhere for the tri-syn...seems like perhaps it was pulled from the shelves???
