Valvoline maxlife power steering fluid compatibility chart

Is this stuff safe to run in our MKIII Supra's. Or do I need to mix it with ATF

How about fixing your steering leaks first? These miracle bottles do not work.

Yea, you should fix the leak. Mine was the high pressure line that runs across the rack and pinion. Good thing my engine was out when we found it, otherwise it would have been impossible to get to it. I went through a bottle of ps fluid in about 2-3 days when I had the leak. After a while, I jus quit puttin fluid in it and drove without power steering. Not too fun, but I got tired of filling the shit up.

Also, I jus noticed it says "ADD TO power steering fluid" on the top of that bottle. I wouldnt run it by itself, jus to be safe.

By the way, I love how 75,000 is considered by Valvoline to be "high mileage"
Please, at that mileage our Toyotas are just getting broken in!
Maybe 75,000 is for domestic motors.

Better off using Valvoline ATF, the PS fluid isn't designed for our systems. That "max life" thing is a crock. Most of our PS leaks are hoses, and those stop leak agents they use might hold the leaks for 75 miles. Sometimes they can slow down small seal leaks, but thats it.

Actually I don't have a leak, not that I know of. I just got done putting the engine in. I got this stuff at wal-mart, and when I read "Add to" line I picked up some ATF Type F to go with it. I didn't read that the cars needs Dexron III ATF. So I am going to go return it.

Z0rn, after what you said about making sure it's Dexron III compatible, the bottle doesn't say. All it says is that it is "compatible with GM, Ford, Chrysler and certain Import Vehicles" NOT RECOMMENDED FOR HONDA OR ACURA VEHICLES. I think I'll go exchange it for some Valvoline ATF. Thanks guys

I didnt know power stearing took ATF! News to me! haha J/k

i thought the ps leak was desigined into the system by toyota as a way to flush the ps fluid....damn guess i was wrong!

if it says safe with GM vehicles, its safe for our ps....probably.
GM vehicles use Dexron Mecron III or better, as tranny fluid,

not all powersteering fluid is Trans Fluid tho, so don't go adding it to your chevy truck's resevoir

Technically, there is not much difference between ATF and PS fluid... both are just hydraulic fluids. ATF has more anti-wear additives, PS has a higher boiling point...

I used to work for a company that manufactured racks and pumps for many different manufacturers ( GM, Nissan, Toyota, Chrysler, BMW )... we did a comparison ( aka 'can our products last until the warranty expires test' ) between ATF and PS fluid in our products, when all was said and done, the ATF pumps showed slightly less wear ( we're talking .000xx ranges here ) than the PS... the racks were similar... there really is no metal to metal contact in a rack, unlike the vanes in a pump..., just gasket to metal... even the valve ( part of the pinion/input shaft assembly ) has three or four faskets on it to keep it from contacting the housing it sits in...

Bottom line... if ATF use shows less wear after 100,000 miles, no matter how slight it may be, it will also wear less many miles later...

Some manufacturers only care that thier cars last till the warranty expires, others care that their cars last... period.
