Toyota branded motor oil has Ti? Since when?
The 88 ppm titanium is between what's in Kendall (100 ppm) and Castrol (10 ppm).
OR--- Maybe there is some titanium wear metal somewhere in the engine. Anybody know?
look at some of my oil analysis reports.. yes Toyota oil does have Ti
in it. so does Mobil
, they switched to it from what I've found because it offers same protections as Moly but cheaper priced.
Interesting, your 5w20 Toyota-brand GroupII conventional motor oil on your UOA did have 30 ppm Ti. As for Mobil, their conventional
oil (Mobil Super 5000) has had Ti in it, off and on, but none of the Mobil1 synthetics
have ever had it. ... pqiamerica.com ... The 30 ppm Ti in your 5w20 UOA is identical to the Ti-Na formula in some Mobil Super 5000 oils, which probably means your Toyota 5w20 was actually the Ti-Na Mobil Super 5000 sourced from Mobil & re-branded. Toyota has long had an association with Mobil, so not surprising.
On THIS thread's Toyota 0w20 synthetic oil, I've never seen that one have Ti in it. And there was a lot of Ti in there, 84 ppm, almost as much as Kendall's amount at 100 ppm.
I've wondered if this Ti thing would ever catch on. Most oil makers don't use it. Kendall, Castrol, some Mobil conventional, and no others I've seen. Afton got some patents off some basic research findings https://www.nist.gov/news-events/news/20...ive-engine-oils
