what oil filter?
10/50 fully synthetic,(motul, valvolene ect) used in conjunction with hi flo filters.
Diesel Oil spec CK-4 not good for motorcycles if it also meets SN, SM and SL.
This 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.
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.
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.
see article Two-wheelers love oil too!
JASO spec'd motorcycle oils are basically the same specs as heavy-duty diesel oil standards except as stated above for the new CK-4 oils.
JASO does not test oils, manufactures pay a fee to JASO and state that their oil meets the specs.
see article, another grade for the heavy-duty upgrade?
even better diesel oils coming into the market with much better wear protection even when using a 10w30 for better mpg. These new 10w30s are showing lower wear numbers than 15w40s.
then there is
notice how they use a bullet proof chevy v-6 for their testing...
