This is premium power steering fluid with conditioners. It's a little higher priced than some, but it's Lucas quality so it's worth it. Would buy again.

following a steering box replacement and complete flush of system pump was a little noisy.replaced 16oz of Power Steering fluid with Lucas Power Steering fluid and no more noise!

Appears to be working great. Slightly thicker than regular power-steering fluid . Good for older powersteering components.

MUCHAS GRACIAS

Had lines replaced at ford dealer. Truck came back with powersteering noise and sometimes hard to steer. Dealer said air in lines and then wanted a mortgage payment to replace pump. Tried this lucas and had to use Turkey baster to get some fluid out to add the lucas. A day later my truck steering noise is quiet and steering feels great. Thanks

Good product

Extracted old power steering fluid, added two bottles of Lucas power steering fluid, like magic it works

I'm not a "let's add some repair in a bottle" to fix a problem kind of guy. I meticulously maintain my vehicles and especially my Landcruiser. It has a gear/engine driven PS pump and when cold it was noisy and labored when turning. I was about to order a seal kit and rebuild it but I have a road trip next week so I thought, what the heck and since it had some good mentions on a Toyota forum I thought I'd try it.I drained as much old fluid out as I could (which only had about 15,000 miles on it), added this product, drove it about 10 miles and then it sat overnight. The next day, my 256,000 mile moaning and groaning PS pump was as quiet as can be.Thumbs up!

PS was making a little growling.Drew out a pint and replaced with this Lucas.Immediately a bit quieter.And seems to be less noticeable as driving.

impresionante, la dirección queda suave y sin ruido

Ford Fiesta noisy stiff power steering improved with just a quarter of a bottle ..... not attempted a full power steering drain and refill ..... just removed 100ml old fluid with turkey baster and replaced with 100ml of Lucas Oil 10442....... I can repeat this process periodically over the next few weeks ...... so far there is a noticeable improvement

Fantastic product, had heavy steering, drained power steering resevouir and filled accordingly.Car steering has been transformed, with lightweight steering and high speed feedback improved.

I needed to flush the PS system in a truck I recently purchased and I decided to go with the Lucas fluid since I've had really good luck with everything Lucas I've used thus far. After flushing it out and getting all new fluid in it, I was impressed. All the pump whine (which was not bad, but it was there) was gone and things were nice and smooth. The old fluid was not terrible (I've seen it jet black before) but it was old and needed changed.For those wondering how to change PS fluid, there are a couple of methods, depending on if you have or are willing to buy a couple of things.Method 1 is simply to remove the return hose from the reservoir and let it drain (into a pan of course). Then replace the hose, fill the reservoir, start the vehicle, turn the wheel all the way one way, then all the way the other then return to center, no more, no less. Shut off the vehicle. Repeat the drain and fill of the reservoir, start the car and turn the wheel lock to lock again. Repeat the drain and fill of the reservoir. Repeat as many times as you need to to get the fluid clean. This works because the fluid constantly recirculates within the pump and reservoir until you turn the wheel. By turning the wheel lock to lock (only once), you are pumping the new fluid into the steering rack or gear (does not matter which you have, they flush the same) and pushes the old out. You need to repeat a few times to get it all. If you have Hydroboost brakes, once you have the steering gear flushed, repeat the whole process but pump the brake pedal 6-7 times and drain/fill the reservoir.If you have or are willing to by a vacuum pump (not a suction gun, they are too big to be effective for this) then you can suck the fluid out into the recovery container that comes with most of them, it's a much cleaner way to go. Process is the same as above, but suck out the fluid instead of draining it. If you do your own auto maintenance, I would recommend picking one up, along with a larger recovery container. You don't use them for testing vacuum components anymore since there are not really any on modern cars, but I use mine a lot for fluid evacuation. You can also use an oil evacuater if you have or have access to one, but I find my hand pump to be more versatile when needed.Either way you do it, you will need a minimum of 2 quarts (that's 4 bottles of this stuff) to get a good flush on a truck, likely a little less on a car, but don't buy too little, it keeps. If your fluid is really dirty and you do not want to use the expensive stuff for the flush part, get a gallon of the cheap stuff from Autozone and flush with that first, then for the last 2-3 changeouts use Lucas so that the Lucas fluid is in the system for use. You also do not need to get it perfectly clean, and you probably never will without changing parts. You'll get most of it out and the fluid will be a light color but not quite clear, that's good enough, unless you just really like buying PS fluid......Be very aware of what fluid your system takes. Almost all cars and light trucks use the generic power steering fluid (which is pretty much tractor hydraulic fluid, but not quite). Medium and heavy duty trucks more often take ATF. If you have a Honda, BUY HONDA FLUID AND NOT ANYTHING ELSE!!! That includes the universal stuff, get the Honda specific fluid. Make for darn sure you know what type to use, ATF and power steering fluid/hydraulic fluid are very incompatible, you will trash every seal in the system by using the wrong fluid and have an expensive repair on your hands. And your Honda will disown you over the wrong fluid... Also take care to use clean hoses if you are vacuuming out the fluid, do not allow any cross-contamination of fluids.That being said, should you use this stuff in your Honda? Well, that's your call. They say it's ok, but I know that Honda fluid is somewhat different than all others, hence the different specification. I have not done the in-depth research to see what the specific chemical differences are. Now with ATF, no way I'd use this. That IS radically different. I know they say you can, but I'm not that brave when it comes to trashing $1,000+ in steering system components... What you do on that one is up to you, you may be fine, all I know is that I've seen the damage the wrong fluids cause, and I will not chance it.Update:I'm now a month ant 2,000 miles later on the flush and the system is working not only flawlessly, but silently. After a week or so of the fluid being the the system, the pump kept getting quieter, to the point now that it is no longer making any noise that I can hear unless I jamb it all the way to the steering lock and hold it. I'm officially impressed, this works better than the professional stuff I used to use in the dealer. It's just a little expensive, but well worth it. Like I said in my original review, flush it with the cheap fluid and final flush/fill with this. I used only this as the flush and final fill as mine system was not that dirty, so my system is probably 90% filled with this stuff.
