I did some thread searching, but never really found anyone definitively saying that this stuff was OK for power steering....and one thing where it seemed the manufacturer was not recommending it? I needed some to do my high pressure hose, and that's what I ended up picking up at Pep Boys...but if it's a bad idea I can probably exchange it...

Probably okay, but why risk it? IIRC, owners manual and WSM say to go with Dex 3.

I think they actually say "Dexron," Dexron III superseded that, and in turn was superseded by Dexron VI. The thing is, if I understand things correctly, current Dexron III fluids aren't licensed, so I'm not sure there is any real enforcement of the original criteria.

Isnt the newest versions of Dextron (i.e. VI, etc) all backwards compatible for the older dextron III and others? says on the lable in most cases.

bureau13

Yeah, it does say that...I'm probably just paranoid about the statement (old, I think) about not using it in power steering applications.

It's probably a bit of a moot point, because I found the mostly-gone container of fluid I used when I replaced the reservoir and it's Dexron VI

GM doesn't say not to use it, but they do say (or did the last time I looked) that it wasn't approved for usage in power steering systems. I suspect that only means that they haven't tested it in every power steering system, so the lawyer weasels won't let the marketing weasels say that it is OK...

bureau13

Yeah, that's the statement I saw...you're probably right about the reason for it.

I've had it in my PS system for a couple of years. Come on in, the water's fine.

I've been using it for a few years in my power steering and no problems. If anything, the effort is reduced slightly. Maybe due to the lower viscosity.

I just used the Valvoline synthetic Dexron VI when I changed my PS hoses and it works just fine.

Thanks for the info everyone. I'll go ahead and use the stuff I bought, if I can ever get this *^%$ing line off....

Chiming in for Valvoline full syn Dex VI... works fantastic for me for 5 years of ownership.

soontobered84

Do they still make IV? I thought that VI had superceded IV.

traxtar928

You're right... it was VI.

I'm swapping my roman numerals...Didn't they go straight from III to VI? At any rate, I'm pretty sure I meant VI!
