an added FYI... I've never run anything but ethanol laced fuel in my E-Tecs - without the slightest problem ... I was worried about it and learned that these motors aren't nearly as fuel sensitive as some brands I can think of. This, when other makes were actually carrying extra fuel filters because of serious ethanol fuel problems, years ago.
I'm very aware that each manufacturer has their own preferred lubricants and fuel additives - and they're a significant profit maker. In the case of BRP - all of the E-Tec power packages were actually computer designed - before the first part for one was ever made... That's why I recommend that you listen carefully to what your dealer (particularly the techs...) have to say. The lower units are little different than they ever were - the powerplants are quite a bit different... very fuel efficient, and absolutely cleaner burning than the newest four stroke (like I said - not your old carbed two stroke at all...).
I chose to run XD 50 oil from the first (when I got my first one the XD 100 wasn't widely available..). It's a semi-synthetic two stroke oil for a 50 to 1 mix. The XD 100 is a fully synthetic oil in comparison but doesn't provide a full 100 to 1 ratio (believe it's around 87 to 1...) -but if you have your tech set the motor up to run on it... it will have to have the XD 100 until it's been set back to run the semi-synthetic oil... No other oil will do (not the case with the standard 50 to 1 setting..).
Post up what you learn and pass on whatever you hear from your tech...
my bad, autocorrect
