Has anyone any experience of AVblend aviation lubricant?

It seems to have been around some time, and is FAA approved. The
brochure says that this oil kept a Lycoming in sound condition for
nearly 8000 hours. That's three engine lifetimes!

I remember reading years ago that this stuff AVBlend was a special oil
that "does what it says on the tin"

TBO Advisor strongly recommends the use of AvBlend on all aircraft piston
engines...
