With regard to the above, do you think a high detergent oil might have an adverse effect?
What I mean is, if this stuff is designed to stick to the walls and such, might a high detergent oil simply "scrape" it right off again?
I'm thinking in terms of the highly advertised cleaning oils like Penzoil...Mobil 1. I realize the most/all oils have detergents but some clean better than others so I've heard
First off mos2 doesn't "stick" like tape or spitballs.
Its a solid lubricant. If you throw a few drop on the wall they will sit there,and benefit nothing.
How it works is the metal contact points(pushrods to cams for example)rub the 1/2 micron particles under stress and pressure and heat into the microscopic hills and valleys of the metals where friction is occurring. Once these irregularities are pressure fed mos2 the create an ultra smooth,extremely durable layer which can effectively reduce the co-efficient of friction. And because the metals are separated by this hard layer there is little to no contact of the actual metal underneath this layer.
At start up the layer is sacrificial and may wear slightly off however as soon as you re-create what put it there in the first place(you pouring in bottle,then heat friction and pressure) will re-apply as long as the engines able to maintain those requisites for an unspecified quantity of time.
In everything I use it in it takes time to layer on enough to be effective. I found that in my Chevy it took 500 miles before I say a significant difference in mileage however my mustand was only 300 miles before it peaked,and wouldn't increase significantly anymore.
I'm thinking 30-40 minute drives with engine stopped until completely cooled is ideal.
I think that there is enough heat and pressure in that trip to allow the mos2 to leave a thin layer. Then repeat after cool down. Lots of layers built up and compressed together leads me to believe that the layers would be welded and unlikely to potentially peel at any given point.
The Chevy was driven to bc with is virgin run of mos2 which is why I believe it took longer to plate. I think the cool down is what hardens them,increasing its resistance to tearing.
I know the organic moly found in PYB leaves only a single microscopic layer which doesn't layer. Its worn off at start up and reapplied when hot and the zddp is active.
Think of organic moly as a type of slick slime. Think of zddp as a polished granite countertop laser cut with not even a microscopically seen irregularity.
Now imagine the thin layer of slim on top of the zddp.
Slick.
Now imagine a marble with an axle through the center and a ball point pens tip pressed against this spinning marble with a solution of fluid that contains a softer type rock.
As the pens tip heats up the rocks physical properties alter slightly and these nano specs begin to become malleable and can be compressed without any voids,all the while being layered on top and compressed
Better analogy for mos2.
Samurai sword. Heat the metal,pound flat. Re-heat and fold the metal over itself creating an incredibly hard,multi-layered product that once cooled is even harder.
At start up that hardened layer has a pen tip pushed into it,dry. Only the mos2. It heats up as the rotations increase and some of the layer melts off until the oil comes to the rescue and moistens the contact points at which time,once it achieves the necessary temp the cycle starts all over again.
This is I believe why I maintain the attained mileage improvements with only a half dose per subsequent oil change.
Well a novella this time.
Lets see who wants to quote and rebut on this one.
The opinions written are my personal observations and assumptions and I am in no way an expert. I merely deduced these observations after careful thought,making the odd leap hear and there.
Similar to the missing link in the evolution theory. I've got a few missing links and I'm confident in the knowledge they will not be found.
Missing links have more fun anyways.
