MANY of them are nothing but snake oil marketing. Many of the oils we talk about for motorcycle "claim" to meet certain standards but are not "certified" that they do by ANY organization, API, JASO ETC.. NOTE: I use the word CERTIFIED, NOT CLAIM to meet. Heck, anyone, including me can post a "claim" on an oil bottle and sell it.
This is why, any reputable oil company (Shell Rotella) that claims to meet in their API CERTIFIED gas/diesel motor oils, Jaso standards.
I am sure is 100% legit and WAY better then motorcycle oils that "claim to meet" Simple because "diesels oils" already are CERTIFIED to meet API Gasoline SM standards AND DIESEL CJ standards which are two classifications with the most rigid requirements on planet earth and "Diesel oils" are CERTIFIED in both gasoline and diesel engines.
Much better off then an oil called "motorcycle" oil that is NOT certified in ANY API or JASO standards and only claims to meet those standards.
I totally understand your point and agree with some of it, but it seems you have a double standard when it comes to this since Rotella only claims JASO compliance and does not register it with JALOS. I don't doubt it would pass the test for the same reasons you mentioned and the fact of Shell being a reputable company, but if your criteria is an oil that certifiably meets the standards claimed on the bottle, then Rotella falls into your "snake oil" category.
You misread my not so clearly written post..
No double standard at all, but my incorrect use of a . and a left out word can easily lead you to that conclusion. We agree 100%, this is how it should have read.

But a better way to put it should have been ...
