See this link below... I ran it just fine in my 2001 Kawasaki ZRX1200 with a shared sump. This ZRX is modded to close to 150hp and close to 90 ft/lbs of torque from 1164cc. NO 15w40 HDEO oil has caused an issue in my cycle or anyone else’s that I have read of.

Rotella T4 was used for millions and millions and millions of miles in shared sump bikes before a JASO rating showed on the bottle...
LOOK at the contents of this T5 oil, it has nothing in the ad-pck that is majorly different than T4 or T6 or any other HDEO. Redline motorcycle specific oils in some cases run well over 300ppm moly, so moly is insignificant if that is something to consider.
I can appreciate caution however it is moot when the “not JASO” card is played when the oil would be just fine based on simple comparison, let alone actual experience runnng it, in my case as one of the best oils I have used in my shared sump engine.
4 & 6 is rated .. why not 5 ?? There must be a reason.
It probably only slightly falls outside the friction requirements of JASO MA when they tested it. (Assuming they ran the battery of testing themselves on this one)
I'm still perplexed that this doesn't meet the Allison TES 439 spec when T4 does; anyone know why that would be? I thought the real limiting factor with regards to that spec is staying within viscosity over many operational hours, and I would think that the synthetic GTL (Shell PurePlus) in this fluid contributes to that end.
