Re: Shell Rotella T6- REBATE
That is exactly what I also think, Terry! I don't think that the formulation has changed, but is it worth the risk? Incidentally, I think that it's a little ironic that Shell kept the JASO rating on the label (even if that's via "self-certification" over being properly certified by JASO), because (going from memory here) if you look at the full specification for JASO MA2, you should see that the oil is also required to meet certain API spec!
Ponch - I know where you are going with that one, and it's what I had in the back of my mind all along! BMW changed from Castrol to Shell in 2014. The wethead manual for the '14 RT promotes Castrol products, but in my '15 RT (manufactured and delivered in Nov. 2014) had changed to Shell. Now, take a look at the available oil out there that meets BMW spec. for our wethead, and you will find very few, with most of them being fairly expensive, EXCEPT for the T6! So, how does Shell eliminate the conflict in favor of the more expensive Advantec (only available here in the US under BMW badge)?
Personally, if I had bought T6 oil, or have some on hand, or for some reasons needs oil while on the road, I would not hesitate to use it. I had brought the subject up just to make sure that you guys know all of the facts and decide accordingly!
