It's Moly rich.
Is lots of moly required to meet any manufacturer approval or pass any test protocol certification? I’m just wondering.
OP, there’s nothing special about it, certainly not these days. When it was first introduced it had one of the highest VIs available, which seemed great until you realized that it had several downsides to it as well. Very high Noack due to very thin base oils, all seemingly in search of a tenth or two of mpg.
There are much better oils available, and no, TGMO is not the same as M1.
Is it back again?
I recall TGMO going from high moly (600-800 range iirc) to not having much (70-80 range iirc, like M1) a few years ago ... Now up again?
Japaneese manufacturers like moly. Theoretically, it sticks to engine parts and make them run smooooth(er) ...
How much (er) and how much less wear, is up for debate like everything else on bitog.
All I know is that all fancy oils (Redline, Amsoil, iirc HPL) have lots of it also!
I use Valvoline when my engines crave moly. I think QS has a good chunk also.
The conventional oils like 5w30 or 10w30 can only do 4k safely before the drag starts to set it. 5k is overstated. Push it over 5k, the liquid will look nasty.
Mom had a new matrix with dealer special oil changes....the "lift" from fresh oil compared to 5k oil was noticeable.

I have a few questions ...
- what is "drag"?
- how does it "set in"?
- how is that "set in" measured?
- why is 5k too much but 4k is "safe"?
And of course moly isn't "moly" in terms of a compound, all you are seeing is the elements from those decomposed compounds. Some molybdenum compounds are more effective than others and require a lower concentration to be effective.
One of the many problems of using a spectrographic analysis to predict future performance of a motor oil.
Yeah that post makes zero sense.
The hype over this oil is much like the hype there was years ago over the weird Denso oil filters used on production vehicles. There was no evidence they were superior in any way, but had a cool look and were unique. Toyota motor oil has an API license and that's as far as it goes.
In terms of comparison to Mobil 1 that depends on which Mobil 1 product you are referring to. Many Mobil 1 products carry a manufacturer approval that exceeds performance requirements for an API license.
There is a TGMO product that also has an ACEA Sequence, but then again so do many other oils.
The hype was centered around Viscosity Index.
And even there that was based on a very high VM load. But lots of people were also gaga over the moly, moly, moly.

I must admit that way back in 2011, I started using TGMO 0w20 in the 2006 Civic that I had just bought that summer. I liked the idea of it having so much moly (at the time I didn’t know about the different types of moly, as it wasn’t discussed here at the time) But another reason why I liked the oil was because the local Toyota dealers were selling it for only $5 CDN per liter, and that was a lot less than what other brands of 0w20 sold for here at the time. I was happy with the used oil analysis that I was getting with it so I ran it for a few intervals until the dealers here jacked up the price.
Well there's nothing wrong with the oil, and I do remember that Canadian customers got the oil for less than we did. Some people even got a "bulk" discount by bringing in their own containers.
It was and remains a completely serviceable oil.

Aside from heavy Moly, (which does not guarantee your engine will outlive the little-Moly oils), you are better-off at Walmart buying big jug Mobil 1 Extended Performance, Castrol EDGE Extended Performance or Valvoline Extended Protection, instead of higher quart pricing of TGMO.
It appears both Boron and Magnesium are on the rise these past few years, with the ILSAC GF6a oils. Less and less Moly showing up on the shelves of Walmart oils. I'm not knocking Moly inside motor oils. But no one has started any threads with proof high moly oils extend the life of your engine.

I use Dove when my engines crave chocolate.
Well if you have a Renault or Peugeot you better use LA MAISON DU CHOCOLAT.
