Yesterday, a freind had mentioned that there was a recent formulation change (reduction in ZDDP) in Shell Rotella T6. I got curious had a look at Rotella T6 UOA and noticed in the pictures below in the link, that there were some differences between the bottles of T6 pictured and the one in front of me, other than mine having french on it. (I'm in Canada) Other than some minor description variation, My bottle of T6 does not have MAN 3275 listed in the specifications & approvals box... Anybody know why this would be omitted, if there is any difference in T6 north of the border or if there has been any recent changes to T6?
