I was planning on buying the prestone equivalent and just topping it off but I have heard on some other forums not to mix power steering fluids.
If only I knew which fluid was currently in there...
Thoughts?
Both fluids are synthetic and meet the 11S spec, so topping off with Prestone should be fine. If you're not sure what fluid is currently in your car, you may want to consider using a turkey baster/suction pump to suck out the reservoir and top off with Prestone.
If it were mine, however, I'd stick with Pentosin. Just a personal preference.
