That is the stuff the dealer gave me as well. Thanks for saving me from posting my photo.MS.90032 OAT Concentrate PN: 68163848AB
The manual states the MS.90032, which is their own internal standard. There's also a 50/50 premix of the same stuff which attributes a different standard to it. I don't know what that number is off hand. It looks to be the one that @rharr posted above.
My local dealership had the concentrate on hand for $24 a gallon.
It's purple, by the way.
