Hi everyone,
I am planning to fill or flush(get some out and re-fill several times in coming weeks) the power steering fluid for my 2012 suburban. Do I have to use the one listed in GM manual? Or I can use general one from walmat, such as Prestone Power Steering Fluid, 12.0 FL OZ AS260Y..

Any comments will be appreciated, thx.

I am not aware of any special additives in the GM brand vs the aftermarket for most domestic vehicles. The only one I've ever heard that is different is Honda...

Thanks, in2pro, then I gonna try an aftermarket one.

The Magnuson-Moss Warranty Act states that if a vehicle REQUIRES dealer fluid or parts to repair it or maintain it to keep a warranty in effect, then they must supply that for free.

And remember that "special" colors for oil, coolant, PS fluid, etc. is a marketing tool for a few ppm of dye.

what does the manual recommend...power steering fluid or dexron trans fluid? don't mix them up
