Just curious if anyone can speak to what happens with moly at the turbo oil bearing interface?
Moly and turbos (turbo oil bearings in particular)

Pablo,
The same thing that happens with any other rotating or rubbing surface. If the hydrodynamic film breaks, the moly acts as a back-up AW/EP additive to prevent catastrophic failure.
Since the oil temps in the turbo are usually higher, I would think the moly would start forming an organometallic surface film long before any hydrodynamic film rupture.

from the 'kule:
Uh, any recommedations?
This is what I was thinking and why I was thinking about adding a little moly to the 'ol Amsoil for the turbo.

Pablo,
I have done the same thing with my '86 Burb. I run Amsoil 10W30 ATM and use the SDF24 Long Version with the following:
1. 1 quart of Schaeffer's #703 10W30
2. 250 mL of Schaeffer's #132.
Will have an analysis later this year or early next year since we have put about 4k miles on it.

I'm not a fan of driveway blending but Red Line has a whopping 600ppms of soluble moly in their formula. If you are looking for a concentrated form of the stuff, I think you will be hard pressed to find a better source.

Bror,
For sure, it has moly out the ying-yang.
I was using the 132 for a few of the other additives contained therein.
As with any blending or experimetation I agree. Without proper research and used oil analysis, it is not a good idea to "backyard" blend.

600 ppm sounds like a bit much....and why spend out the yangse for Redline, when I can spend out the yangse for Amsoil!
I was thinking in the 150 ppm range...
BTW I agree with the blending comments. I would NEVER tell a customer to do such a thing. Sometimes I need to satisfy my wild hair....ocaisionally I ruin something...you can ask my wife

Well, at least you're man enough to admit it!
