TGMO High Moly

[artbuc]

Just bought a 2024 Venza so started reading about 0w16. Data shows TGMO has high moly, no doubt about that. Someone stated that moly comes in different forms, some more effective than others. Contention is low moly M1 is just as effective as high moly TGMO. Is there data that proves this theory?

Here's a blog post discussing this:

"One thing I can say though is that the type of moly used will be dependent on which additive company they are sourcing their additives from - there are only a small handful of them out there. For example, ;Infineum, which is co-owned by ;ExxonMobil and Shell, uses a "tri-nuclear" type of moly in their additive packages. Tri-nuclear moly happens to be a much more effective flavor of organic ;MoDTC that can be used in much lower concentrations than the more traditional types of moly. ;With treat rates of the trimer type of Mo FM, usually 70-100 ppm is all that is needed to get effective protection/friction modification.

When you see a VOA or UOA of a motor oil that has say 700+ ppm of moly in it, than you can be sure that that particular brand is ;not ;using "tri-nuclear" moly in their motor oil. I believe ;Idemitsu is one brand that is still using the older more traditional type of moly in their engine oils."

Most of the Japanese auto companies use Idemitsu oils. It's possible that they're all in agreement that their engines need high moly oils, but it seems more likely that they will naturally partner with the Japanese oil company, who just happens to use a certain type of moly that requires higher concentrations to be effective.

Thank-you very much for that.

But TGMO for the North American market is manufactured by ExxonMobil. That must mean that for whatever reason Toyota specified the "regular" moly for NA TGMO.

TGMO comes at a higher cost, that is for sure
