Johnsen's 4611 Power Steering Fluid - 1 Gallon

Used this power steering fluid conditioner in my older truck and it definitely helped with the whining noise I was having. Easy to use - just pour it in and it mixes with the existing fluid. Steering feels smoother now and the noise is mostly gone. Good value for the large container size. Seems like quality stuff that does what it claims.

Good price for one gallon.

Good value and worked when I had a bad leak and had to fill my power steering every day

No more noise or leaks. I was having to fill up with other brands every 2-3 days. I figured I'd get a gallon supply so ended up with this - but it solved the problem after a couple of top ups

It's a good product

This is an exceptional product! I was amazed that apparently its seal conditioning properties reduced the leakage significantly, better than separate top tier stop leak products that I had tried. Frankly I only bought it to refill reservoir as needed due to severe leakage (vs. expensive repair) but was pleasantly surprised (shocked?) at how it also "mitigated" the main issue. You can just tell this is a quality product from a quality company and quite favorable priced as well. Could not possibly recommend more strongly.

I bought every different kind of power steering fluid on Amazon from the cheapest to the most expensive, and none of them worked to make my power steering work. There is a leak of some kind that caused my power steering to harden so that it was hard to steer. After a year, I gave up on the idea that this can be fixed without a mechanic. However, with all the positive reviews about this magical liquid, I decided to give it a try with many doubts as many other steering fluids I purchased with positive reviews never worked. I can positively say I am so glad I turned to this fluid as a last resort. It saved me from needing a mechanic. I poured half the container into my car a half year ago, and the power steering remains smooth. I plan to buy more just in case, but the price seems to keep going up. I will wait for the sales when this comes back down closer to $20.

Silenced my whining power steering pump, whose fluid had turned black over the years. It should be noted that this fluid is NOT for Honda or Acura power steering systems, as per the back label (they really should print that on the front label, IMHO). Used a basic fluid extractor (Sedy brand, less than 10 bucks) to remove fluid from the power steering reservoir, so I could easily replace the same amount into the very inconveniently placed power steering pumps on my cars. Anticipate that this can be a bit messy, so have shop towels, rags or paper towels covering nearby belts or hoses, etc., just in case.
