I am not sure but Phillips seems confident there Turbo oil with Moly is up to the task. Would not want to see burnt moly though. Where is a moly guru when we need one ? [Smile] TTT [ November 24, 2002, 09:52 PM: Message edited by: dragboat ]

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.

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

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. [Wink] --- Bror Jace

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 [Embarrassed]
