The power steering is starting to bind up and make some bad noises in my Dad's Olds 88, so I tried Lubegard as a last resort to changing the pump/rack. The stuff rocks! It's 75% better. I recently used Lubrgard gear fluid additive in the transaxle on my Corolla and it helped shifting noticeably and quieted the input bearing noise. I'n not much into additives, but Lubegard is the real deal. Not snake oil at all.
