Yeah, I used it in my boat (twin diesels) a couple of years ago. I think it's been around for a while.

It seems to work OK, since the fuel in the boat was several years old. I just took a minor trip in it & never missed a beat.

I also tried Startron, which noticably cleared up the fuel itself. In the filters (have a clear bowl) the cloudy fuel cleared right up. Again, the Detroits never missed a beat.

I'd say go with the Startron. It does the same or more that the Sta-Bil, but at this point I would say that it would be personal preference.
