Hey guys, not sure if this is the right place to post this but, how do i know how much auto rx to add to my power steering fluid? Where can i find out how many quarts of power steering fluid my car holds, its a 95 lexus gs300. How many quarts is the norm?

Also, is it normal for the power steering fluid to be black?

Thanks guys

If you can't find the exact capacity of your system I'd go with 2 ounces. It is NOT normal for PS fluid to look black. This indicates to me you've got some dirt or other contaminent finding it's way into your system. Check all your clamps for tightness. Because your fluid is so contaminated expect that you may need two or three flushes after your ARX application to get the fluid looking like it should.

Deteriorating rubber components might be the source of the black color. Hard to say.

I'd agree with the 2oz. It should be within the range where that will be enough without being too much.

Power Steering is 1 ounce of Auto-Rx. If you have a leak 2 ounces. Rest of application stays the same.

According to the website application guide, here is the doseage:

To get the most out of Auto-Rx, we recommend the following methods of use:

Auto-Rx ratio is 1 ounce per quart of power steering fluid.

Drive for 1,000 miles and drain.

Refill the power steering system according to your vehicle manufacturer's recommendation.

How often should we do this?

"How often should we do this?"

I would let the color of the fluid be your guide.

I would probably say to do this every 2 years or 30,000 miles.

My plan is to do the PS evrytime I do the tranny (30K OCI). I just wanted to verify that the PS wasn't just a one time only item.

It can be done as often as necessary as ARX is not going to harm anything.

Do the one oz. If you truly drain your power steering system (by disconnecting the low-no pressure return line and pumping new fluid through = measuring) and find that you have above 1.5 quarts of capacity, go two oz. the next evolution in 30k.

Check yer manual to make sure what kind of fluid to put in there. I know Toyotas usually take ATF instead of PS fluid...not sure about Lexus vehicles. ;)

1 ounce is fine if you have leak use 2 ounces drain and refill with new fluid after 1000 miles.
