Really? 2-cycle oil will up the lubricity considerably? Not according to this study...http://www.natbiogroup.com/docs/education/lubricity%20additive%20study%20results.pdf
That study shows that a comparatively tiny quantity of the cheapest 2 stroke oil makes a huge difference. A 0.5% concentration results in a 162 micron improvement. At the tested 200/1 ratio, the cost is mere pennies per tankful.
My tests were done with Penzoil TCW-III Semi Synthetic Premium outboard oil at 100 to 1, a better oil, at twice the ratio. Plus I also used a double dose of Stanadyne Lubricity additive.
I spoke with the HFRR rig tech, he has been doing diesel fuel testing for years. Hence the 3 samples I sent in. They were not my original "guesses" but rather suggestions from the tech, tailored to my engines' needs.
It was his way of showing me what was required to make Jet-A work properly in a precision diesel. You know what? He was right. It took significant additives to make Jet-A meet the requirements.
FYI, there was some discussion between us about the film strength of the 2 stroke oil preventing metal to metal contact and that the Stanadyne product helps prevent scaring when that film strength is insufficient. It was his contention that they were somewhat different in modes of protection.
