Same thing. LolOpps....is purple
If you say so.
The best thing is to give a try as I did, I tried many brands I will stick with this one.
I want to thank you for posting here about your experiences with using certain brands of tcw-3 oils in your fuel. I have read your posts on another Forum. I am in the same boat to a certain extent as you are, since I have used Pennzoil XLF, Pennzoil Marine Plus, and Amsoil Saber Outboard in my fuel at the recommended dose of 1 ounce to 5 gallons of fuel. I do have a favorite but the problem is that it is a feeling and I cannot prove what I am feeling.
True what you say, but one thing is that has improved the cleaning, I do not use system cleaner yearly anymore....and there is a feeling of more compactness of the engine....

I am a tcw-3 user in the fuel, but the improved cleaning thing is baffling, it is almost like you are saying the Mystic tcw-3 you are using is superior to any other tcw-3 oil that you have used. With the different tcw-3 oils I have used I have felt a difference, but I cannot prove it.
I have run WM Super Tech TCW-3 at about 960:1 ratio (2 oz. per 18 gallon tank) for upper cylinder , fuel pump lube & system cleaning . *I tried at the recommended 640:1 ratio and my gas milage was not as good as the 960:1 ratio I currently run .

Q1: What's the ppm concentration of the components found in 2-cycle oil after pouring 2 oz. into an 18 gallon tank?
Q2: How is a fuel pump lubricated? This one always got past me.
Less than scientific but I use this calculator : http://www.csgnetwork.com/oilfuelcalc.html . I just played with the TCW-3 oil ratios until I started to see a reduction in MPG using the same fuel from the same gas station (I tracked every other fill up when I would add TCW-3) . As far as the fuel pump is concerned - I merely go by sound using my preferred concentration . Again , less than scientific ...
I suspect they are talking about high pressure fuel pumps, like common rail pumps or GDI pumps. Both use fuel for lubrication.
and the low pressure pump could be this type, I have a stand alone oil pump designed to suck oil from the sump using this. There's quite a bit of moving parts

Exactly.
You would have to use a whole heck of a lot of two-cycle oil to change the lubricity of gasoline, and then that would affect the octane rating, burn rate, etc., etc.
The fuel pump, and the materials of which they are constructed, are designed to work with the nominal lubricity of the fuel.

In the first question I was asking about the chemistry that is included in two-cycle oil. Any chemical component is going to be diluted beyond measure in gasoline.
Today, and in order to get the lean mixtures required for clean exhaust gases, a minimum of Group III through Group V base oils must be used. Now to the additives. As others have stated, no low-cost two-cycle analysis will tell you all of the chemical components included, only the basic organo-metallic components that can be detected. The calcium and the magnesium combo is a mild friction reducer but primarily serves as a detergent that minimizes carbon deposits, but not all deposits. In modern 2C oils, this is up to the synthetic base oil mix, usually comprised of one of more ester base oils. One anti-wear component seen is the low treatment level of ZDDP, the zinc and phosphorus. This is a special ZDDP ester with a low level of sulfur. A cold-start anti-friction/anti-wear additive containing a boron compound may be added. The Tin is usually tin napthenate or Tin dithiocarbamate (DTC), another anti-friction component. Mobil uses a Titanium DTC for the same reason. A high-flash solvent is incorporated to keep all of the components in solution and to make it miscible ("mixable") with the fuel. Now if higher ester levels are used, less of this solvent is needed. Another anti-wear/anti-galling component, that also is used to thicken the film, is a polyisobutylene Group V base oil. A small amount of a sodium compound is used to inhibit rust on the steel components. Not seen in analysis is something called a dimercapto 1.3.4 thiadiazole compound, an anti-corrosion additive. The last component that is used that does absolutely nothing is the Blue organic dye.
All of these additive components and base oils are in the low ppm levels so when 2C oils are diluted in gasoline, only trace levels would be found in the gasoline.
PIB can be high though, echo states around 30% of the mixture, but if someone's using a 1:600 mix it's obviously back down to 0.05% or 500 ppm
pib/piba changes droplet formation, this could be reason of nvh change.
anyway, i´ve used local pea/pib stuff which is quite high content.
but using fullsyn tcw3 feels better.

Essentially, a waste of time.
