I have two of the black max engine savers. Nice thing with these units, is that there is no need to renew/bake desiccant. Down side though, is the system is more complex, so more things to fail. I have had to send the device back to the manufacturer for repair, but still recommend and have had excellent service. One plane I use it on has the larger oil breather tube, and the other has the small breather tube. On the larger one, I modified the air plug to sandwich a round piece of silicone sheet, and glue in place with high temp rtv. This works well for me to get a good seal. The factory foam was getting tore up from the small hole in the breather tube. My oil analysis reports did get better after I started using, but not sure if that was the dehydrator or my flying habits.
