I recently purchased a quart of Supertech power steering fluid to do a few drain and fills of the power steering system on my Dakota. Reading the back of the bottle while refilling the system I noticed that it said to only use for topping off the reservoir and not for complete system refill. I never noticed this before on power steering fluid. I only did one exchange of the fluid using the turkey baster method. I'll probably just go buy a different brand of fluid to do the rest. Does anyone know why it would have such a warning on the bottle? Could it be a poor quality fluid? Thank you in advance!
