Take a look at fig. 1 and 2.


Quote:
By blending
SpectraSyn Plus PAO and conventional
Group III base oils, formulators can meet
challenging cold-cranking simulator (CCS)
and volatility targets while maintaining the
lower viscosities that maximize fuel economy
 
I think that figure 2 shows why Ester-based oils often have higher Moly -- its because they have to use more just to get equal performance to lower levels in less polar oil. It seems to me that Redline oils don't have extra moly just to entice BITOGers. I think that they may need that much moly just stay at par with competitors for boundary lubrication.

I recognize the other benefits of their base. I am only referring to boundary lubrication.
 
This is why my mix of

1 quart of Mobil 1 Racing 0w30 (Ester)
1 quart of Mobil 1 0w40 (PAO)
1.6 quarts of Mobil 1 5w20 EP (Group III)

.....is going to be so successful.

I guess you haven't read the 0W-40 made with/containing Group III base stocks threads, have you?

Mixing oils like this doesn't accomplish any benifit for the engine. Now for the mind, could be something else.
Also no oil that I know of has a straight PAO. Blending base stocks produce a better base than straight 3-4-5.

I know M1 0w40 isn't a majority of IV like it used to be. But it's still in there. Same with the 5w20 EP. Yeah, both are mostly III+, but it's a source of PAO. I'm sure the 0w30 Racing isn't 100% Ester either.

But tig1...."Mixing oils like this doesn't accomplish any benefit" .... isn't that what this link is trying to say?

I believe the document is targeted towards actual blenders of base stocks that work for oil companies, instead of "backyard blenders" that mix a finished product.

So me adding a little bit of a high moly containing additive into my expensive, ester basestock containing oil, is NOT a "harmful waste", nor deserving of all of the berating one recieves on here, from so many, for doing such?

Interesting take on things... You may be 100% right!
I add a little Lubro Moly to my oil.
