I installed this on
Honda S2000

Review
The positive reviews read online seem to be correct. I have been having trouble with my Power Steering, after replacing pump, belt, adjusting belt, a fluid flush, the power steering has still been giving me trouble during the first 3-5 minutes of start up. After using this additive , there is a noticeable improvement. The power steering still needs a few minutes upon start up , but now I can actually steer the car during the first few minutes. I bought more of these and added a little more then added some to my other car as well.

What I like
Only after adding this additive that I feel more confident in steering more aggressively without worries.

What I do not like
The price
