The Stanadyne/Power Service stuff is proven useless for improving lubricity beyond the fuel manufacturer's levels, where the TC-3 2 stroke oil does improve it.

Stanadyne Lubricity Formula
Lubricity Only
demulsifier, 5% bio-diesel compatible, alcohol free
HFRR 479, 157 micron improvement <<<<<<<<<<<<<<<<<<READ THIS.. What part of improvement don't you get????????

Same as two-stroke and cheaper.
4)Opti-Lube Summer Blend
Multi-purpose
demulsifier

Better than two-stroke at HALF the cost.
Minor improvement, but you still miss my point. Here is the conclusion...

CONCLUSIONS:
Products 1 through 4 were able to improve the unadditized fuel to an HFRR score of 460 or better. This meets the most strict requirements requested by the Engine Manufacturers Association.
Products 1 through 9 were able to improve the unadditized fuel to an HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for maximum wear scar in a commercially available diesel fuel.
Here is the rest...

The U.S. standard for diesel fuel says a commercially available diesel fuel should produce a wear scar of no greater than 520 microns. The Engine Manufacturers Association had requested a standard of a wear scar no greater than 460 microns, typical of the pre-ULSD fuels. Most experts agree that a 520 micron standard is adequate, but also that the lower the wear scar the better.
So the point is even Standyne Lubricity formula does not improve lubricity to the point where it meets the
engine manufacturer's recommendations. I never made a point about Optilube, but if you read the rest you can see Power Service is next to useless, and Stanadyne Performance is even worse.
