I would think that many here would be using it. I am a former trbologist, who strayed and became an IT Director of R&D. I also race and restore old Corvettes, and recently bought a Honda S2000 with that sewing machine RPM capability. I have access to the spectrometers, gas chromatographs, and scanning electron microscopes, so it allows me to dabble in lube research a bit, including looking at wear particles/asperties with great precision.
I found LE while looking for a 90w gear oil. That is what Honda recommends, which is unusual in this day and age. The S2000 uses a shotpeened version of the Miata ring and pinion, so I wanted better shock loading. Anyway, I had all but given up on finding a quality 90w with some decent low temp capability, and found LE from a former tribologist associate. They make a product called LE 607, which is petro based, but either very highly refined or with some PPD, because its pour point is -11degF, which is very low for a 90w (Schaeffer's is +5degF in 90w). I ran some tests, and found it had much higher EP load tolerance than any 75w or 80w90, including my RedLine and Amsoil synlubes. 3-4x!
So I also started looking at 8130 and 8530 (5w30) engine oils. 8130 has high phos, and is SH-rated as a result. 8330 is SL-rated. They demonstrated outstanding anti-wear performance in our etsting, and a high resistance to oxidation and shear, surprising for "only a synblend. Goes to show what careful refining and additive magic can do!
