So my buddy has some motul oil from a few years ago and the sticker says motul kart oil (picture below), but on the back it has the 2T. Is this any different from the current branding of the 2T oil?
It is likely the same thing, but with the change in packaging its probably several years old. Most synthetic oils have a shelf life of about a year or two. The date stamp looks to be about a decade old. You may want to contact the manufacturer to confirm.
