According to the link:
SL Current For 2004 and older automotive engines.
I am no lawyer but I don't have an automotive engine in my motorcycle
According to the web site for Actevo:
Features:
Outstanding high temperature oil consumption and oxidation control
Exceeds API SG, JASO MA2
In the long run, does it matter? who cares? Run what ya want. Maybe it's a marketing gimmick for motorcycle geeks? I would be pretty square not to use it on my wet clutch Suzuki. That's a definite no-no. Or better yet, Suzuki convetional oil which used to be $18/gallon, now $40.
Yep, that obsolete SG oil will probably cost more than the new SL stuff.
