1. Full flush of 2005 Buick Park Avenue with 60,000 mi.
Out: Mix of factory fill and a few yearly reservoir siphon-and-fills of STP, Valvoline PSF, Mobil 1 ATF, and ATF+4. It was clean and working fine, but who knows if that mix was OK for the long run?
In: GM power steering fluid. Used 2 qt to flush fully.
2. Full flush of 1998 Dodge B1500 van with 50,000 mi.
Out: Mix of mostly factory fill and one siphon-and-fill of whatever I had at the time. Fluid was dark.
In: GM power steering fluid. Used 2.75 qt to flush fully.
