My first impression, load of crap.
"The trouble with that is that creating turbulence close to an air-solid interface is going to RAISE the heat transfer coefficient, not lower it."Well this is a bit of a head scratcher. Most significant I think is their claim that the dimples create turbulence, which allows the combustion air to burn hotter closer to the metal. I understand that to mean that the turbulence is lowering the heat transfer coefficient between the air and the piston, so the air stays hotter and more of its thermal energy contributes to mechanical work rather than being lost into the piston. The trouble with that is that creating turbulence close to an air-solid interface is going to RAISE the heat transfer coefficient, not lower it. I smell a rat.
I've spent the last few years primarily doing computational fluid dynamics and heat transfer between air and solid surfaces.
On the other hand, such things are difficult to figure out just by looking at them. A scientific paper with data and an underlying theory could lay all this out in a way I'd be inclined to trust, but the advertising article linked doesn't do that. I'm going to rate this "funny, doesn't sound right, but not yet proven to be snake oil beyond a reasonable doubt".
All the golf balls I have used always go off course to the left or right, never have seen the go farther part. Except farther off course. LOLGolf balls go further with dimples, why not engines ?
I’ve never tried burning crap in my tractor. I wonder how much fuel improvement it will make.My first impression, load of crap.

Try farting into the air cleaner. It might work.I’ve never tried burning crap in my tractor. I wonder how much fuel improvement it will make.
