Johnsen's 4611 Power Steering Fluid - 1 Gallon

Works well, affordable, and a solid product. Cant go wrong with it

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

Let’s be real — reviews are subjective. What feels like a game-changer to me might just seem “meh” to someone else. I tend to hand out 4-star ratings pretty often because, honestly, most products do what they promise — they work as expected, meet the description, and get the job done. That’s solid, but not necessarily spectacular. For me, a 5-star product has to go above and beyond. It’s either got to bring something truly innovative to the table or impress me by outperforming what I thought was possible. Just meeting the standard? That’s commendable, but it’s not five-star territory. So keep that in mind — this is my take, and your experience might vary. You might love it more, or less. That’s totally fair. Now, onto the product: I received the Johnsen's 4611 Power Steering Fluid (1 Gallon) through Amazon Vine, and after using it in my vehicle, here’s how it stacks up. This isn’t flashy, but it’s functional. It’s a blend of mineral and synthetic oils designed to keep your power steering system running smoothly. I’ve used it to top off and refresh my system, and I did notice a reduction in that occasional pump squeal I’d been hearing — a win in my book. It claims to stop noise, prevent slipping, protect seals, and reduce abnormal wear. In my experience? It delivers on those promises. No leaks, no new noises, and the steering feels as smooth as expected. It’s not magic, but it’s reliable. If you’re looking for a no-frills, effective power steering fluid that does what it says without overpromising, Johnsen’s 4611 fits the bill. Not revolutionary — but definitely a solid 4-star choice for routine maintenance.

Good price for the volume

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.

Good product
