I got my hands on some of this new kendall "liquid titanium" containing oil (the 10w30 hi mileage variety, from pep boys). I noticed the stuff has a strong sulfur smell to it. I'm guessing the liquid ti is titanium sulfide; indeed, "Titanium disulfide has been proposed as a solid lubricant. The coefficient of friction between steel surfaces is .3 compared to .2 for molybdenum disulfide. However, because it does not adhere strongly to metal surfaces, TiS_2 is generally less effective than molybdenum disulfide," according to pg 48 of

.
If it is in fact Ti disulfide, this additive would have one or two things going for it versus moly disulfide. 1. concentration is higher by 3x or more (~1000 ppm according to kendall specs' pdf, vs typically ~300 ppm for typical moly additive fortified oil. And secondly, possibly, 2. slicker coeff of friction is not necessarily superior for antiwear (for example, zddp has a high coeff of friction but is a superior anti wear additive--maybe intuitively once can visualize a spongy springy type of material that would be a great antiwear buffer material between the two hard steel surfaces).
