CK-4 oil is not junk as he stated. one of the top additives being used now is Boron, see my two posts.
from my earlier post
http://www.valkyrieforum.com/bbs/index.php/topic,96825.0.htmlThis new spec requires below 1000ppm of phosphorus and zinc if the oil also is to meet SN, SM and SL gasoline engine specs. Levels this low will wipe out the cams and rocker arms. Ford has already come against this spec citing excessive wear in powerstroke engines.
http://fordauthority.com/2017/03/ford-launches-new-oil-spec-for-6-7l-power-stroke-diesel/So far Motorcraft oils have a new Ford specific spec which has higher levels, and early testing shows rotella is maintaining the higher levels and is rated CK-4 but not SN, SM and SL.
All Delos are below the 1000ppm level.
Present CJ-4 spec oils which are above 1000ppm are being phased out. So stock up.
So make sure to check your oil of choice in regards to this new spec.
This site does virgin oil analysis of oils and is starting to post the CK-4 oils.

JASO spec'd motorcycle oils are basically the same specs as heavy-duty diesel oil standards.
JASO does not test oils, manufactures pay a fee to JASO and state their oil meets the specs.
see article, another grade for the heavy-duty upgrade?
even better diesel oils coming into the market much better wear protection and using a 10w30 for better mpg.
