I believe it is GG. So is the 'Nulon', I have been using. It was
always my understanding that the precautions were mainly with regard to
ensuring filters were regularly checked after initial application, in
case of Jelling with any foreign substances not already properly removed
from the oil, and causing blocking. As well as the same circumstances
causing blocking and misreading of pressure guages. I suspect that was
the effect in the engine you tried it in......not a problem with your
oil pressure, but the readings your guage was giving.
There is nothing wrong with the process, and as I described in my
previous postings I have had 'continued success with extended use'. But
I took precautions of ensuring all components and housings were properly
cleaned before applying. The P.T.F.E additive is designed to work in a
mixture with certain oils. and set up a coating of the moving parts
working in friction. If foreign bodies are kept clear and filters
regularly maintained, then pipes and byways to ancilliaries will be
clear enabling them to work properly.
