I havent looked, but I heard Rotalla T 15-40 has been tested & rebadged AS a motorcycle oil recently. Not due to a change of formulation, but because it is & has been formulated so that it passes the test.
To be clear, it isnt in a jug that say
"I am a motorcycle oil", but hasd the same symbols & stuff on the jug that motorcycle oils have. Just so happens, its also so good of an oil that diesel engines, you know, the ones that crush their bearings so as they compress the fuel/air mixture so hard that it ignites, run for hundreds of thousands of miles,
