XADOPower Steering Fluid Oil Additive EX120 - Metal Repair Conditioner and Revitalizant for Steering Wheel Booster and Hydraulic Equipment - Protective Fluid Treatment from Wear (Syringe, 8 ml)

I actually noticed a difference immediately. My 2010 Chevy Avalanche Z71 has 120,000 miles and has always been super reliable. We always perform recommended maintenance schedules and use synthetic oils. Since day one the Powersteering has been noisy... the dealer says it was in spec and had no issues other than a little noisy. Immediately after the XADO treatment, the action was notably smoother and the noise was almost gone. This is an excellent product and worked as advertised for me. I also used the Motor treatment and also noticed almost immediate smoother operating and less noise. Very cool. I have used dozens of products over the last 40yrs of driving and this one is the first to actually deliver a result I noticed immediately. Just ordered for my wife's Lexus SC430 with 110K miles. Recommend this product... seems like the real deal.

I've used XADO on two different older vehicles at around 150K. On both, within a few hundred miles, i noticed a big difference. I felt like there was resistance when i turned the steering wheel, and it made them oversteer with small corrections. On both cars, the steering is now smooth, effortless and precise. It's truly amazing.

I added this to my power CHF 11S steering fluid for my Porsche Cayenne 958, so far I have seen some improvement, and all sounds when steering (specially when stationary) have disappeared.But since it states on the bottle instructions that it cannot be added to old steering fluid, I had to replace the original fluid, so I am not sure if the improvement is in reality because of this additive or because of introducing new fluid.It does state that the effect will take some time and to be honest I am not using my Porsche a lot these days.I will try to update the review in a few months.I gave 4 stars because there is an improvement, it looks decent, is well preserved and has clear instructions (which I believe many of the negative reviewers did not take into account).

Ok

Stopped the moaning sound coming from my power steering box in my '94 Ford Taurus 3.0. Flushed the p.s. box at Pep Boys and refilled with Lucas Oil 10442 Power Steering Fluid with Conditioners - 16 oz.. Added Xado when finished. About one year later, noise returned and steering pump had to be replaced.Tried this product on a '00 Mercedes ML320, which didn't really have any problem. Xado immediately created a loud moaning noise and the steering pump had to be replaced.You've been warned!

Smooth

I don't understand what this is or why it works 210k on the power steering pump and I started to hear some noises put this in and now I don't. It will probably fail later nothing lasts forever who knows but it's not making noise.

About 4 years ago i used this product in my 2004 subaru wrx. The steering rack was acting up and it was notchy and hard to steer. After adding a siringe of the xado following the directions and driving the car for about 10 miles the steering was better than ever and has been fine since. I add a dose every year when i service the ps fluid.I'm a mechanic and most additives and treatments don't work as advertised but all the xado products I have used do seem to work! I saw the most noticeable possitve result from the power steering revitalzant and Manual transmission xado revitalzant.
