I don't believe this design is going anywhere. I recall seeing this thing many years ago. I believe efficiency and emissions is a major hurdle.

but the real question.. what oil spec and filter does it need???

It was called a ' swash plate ' engine back in the '50s . No real point to it though it works ok as an AC compressor .
