After seeing pictures of how it collected in oil pans in vehicles that weren't driven everyday, and pictures of
@Trav's compressor motor, which he added it to, I'll pass. It was collected at the bottom and did not go into suspension even after running the machine. What was interesting with the vehicles that weren't driven daily, even after they were started and the oil pans removed the product was still settled at the bottom of the pan. I'm sure some mixed in, but not all of it, that was all I needed to know. Still some people will argue or say they drive everyday, and defend the product. So I say to them go for it! Or search the archives read up on it and decide.
