I have a 2005 C6 and I was wondering if you could use Pennzoil Power Steering Fluid in it. It was the only thing available at the local store and I need to fill it up. The reservoir is somewhat low! Thanks.

I use the Gm stuff, its cheap and the dealer always has it.

The Pennzoil stuff says it compatible with all power steering fluid.

Whatever you do, do NOT use the Valvoline "synthetic" PS fluid. I tried it in my C6 and had major issues to the point where the car was undriveable.

I only use the GM Power Steering Fluid. I know it is the right stuff. A GM dealer "should" have in in stock in the 1 quart containers.

I have a quart of GM#89020661 that I used in my 02 Z06, now I have a 08 Z06 and the GM part number for the is #89021184. So your saying same stuff but different part number because of the size of the bottle? Does anyone know if this is the same fluid and be alright to use? Thanks. Happy Holidays

i had no problems with my wifes 05 Z51
what i do is use my old turkey baster to extract fluid out, and refill with new
i do this every year in my other cars to keep some fresh fluid in the system
there's alot of heat going on in cars now-a-days so keeps everything nice and clean

same goes for the brake master cyl

When I went to wet my new and dry power steering hydraulic system in my 68, I went to the local auto parts store. All of the power steering fluids available proudly advertised that they had additives that prevented leaks. To me, this meant that they were formulating their PS fluids to be used in DD beaters. From my C3 forum readings, Jim O'Shea, a retired Saginaw engineer, who was involved with PS developments for the C3's had compelling reasons to not use anything but GM PS fluid. From his writings, it was evident GM spent a lot of money and used a lot of expert input to develop their PS fluid. I'd guess this is true for today's C6's. I'd recommend getting GM power steering fluid from the local dealer.

Once again....if the auto parts store PS fluid advertises that it has anti-leak additives.......run (in my opinion).
