Jim -
At some point, I would want to get some kind of consensus on oils/brands to test. I haven't thought that far ahead...kind of waiting for the organization here at my work to give me some guidance.
My thoughts were:
- have some connection to past oils tested (for continuity in different tests)
- concentrate on SG/SH rated oils, maybe include oils that have a later grade but still "meet" SG/SH (so that say!)
- I don't want to get too wild and crazy about viscosities...the Airheads take 20w50, maybe 10w40 in some situations
- some mix of dino and synthetic and semi-synthetic
As this moves forward, I would take a look at what people suggest plus oils that I've heard about in recent discussions.
RE: the Redline...can those zinc and phosphorus numbers be right? If the numbers of 0.25% and 0.21% are right, that's bordering on being too much from the reading I've been doing. I think that more is not necessarily better.
This all sounds good to me, Kurt! I think you're developing a good approach that will yield informative results.
In regard to the Red Line oil, the zinc/phosphorus levels certainly appear higher than any of the analysis in the Di Carlo article (although I haven't converted from %wt to ppm, so it may not be as big a difference as it appears?). I did poke around on the Spectro and Mobile 1 websites looking for info, but didn't see any posted data on their wear additives (my web-sleuthing skills are marginal, so it may be there and I just didn't see it!). My thought was that the Red Line posting was unique in the sense of it could give you manufacturer data to compare against if you include it in this analysis.
This is a neat project- looking forward to the results!
