Yep..the old Rotella is about gone. Still can find it in qts. around here. The new stuff (container has yellow and blue on it and dated 2007) has a lot less zink. The old stuff is in a blue and white can and dated 2004. I have at last got our G.M. dealer here to agree to stock the EOS. I have 12 qts.of the old Rotella put aside as I plan ONE MORE motor build next year for a Bonneville project then "thats it" I then move into the "been there ,done that" mode...SCRAP
