No thanks to the oil stabilizer. I'll trust the professional chemists at Shell, Ashland, Exxon, etc before I'd trust them. Especially because it is so generic, even if it worked, it likely wouldn't work equally as well with all oils due to different base stocks, and addpack chemistry.
I did use their PS Stop leak stuff once in my cavalier when I changed the fluid with Valvoline High-Mileage PSF. Together, it really quieted down, and smoothed out the power steering, and decreased effort when stopped.
I've used the UCL when it's been buy one get one at Advance.
