Oil Nerds Info

I'm trying to make a decision on oil based on objective data rather than anecdotes or theories about what should and should not work. Whatever decision criteria anyone else chooses to use is his business.

Also, I haven't ruled out Redline, I'm just not sold on it based on the information I've seen thus far.

What I'd like to do is try to match each oil's adiditive spec sheet to the results and see if there's an obvious pattern.

In keeping with this idea, some of the oils with the lowest wear ratings in that data set also have the highest concentration of molybdenum, which is added specifically for that purpose.

Also, allegedly, some of the oils favored by racing teams provide superior protection only with more frequent change intervals -- I need to do more research on that, but the implication is that for a DD, these oils may not be ideal.

Regarding your post -- yes, apparently some of the tests oil manufactures report findings for are more appropriate for testing gear lubes and greases rather than engine oils (alledgedly Amsoil is especially guilty of this) -- that's why I take independently gathered wear data from a highly similar engine more seriously than theories about the meaning of various spec sheets or oil classifications by themselves.
