Today, I bought some Mobil1 ATF, a turkey baster, a few feet of plastic tube and went home with the idea of doing the power steering fluid exchange by sucking in and replacing as much fluid as I could. I dripped the fluid into a clean sheet of paper and the thing looked like it was just poured in. So I did not even bother to do the change. It seemed to me like it was in real good shape. Should I still have done the exchange? I will do a drain and fill of the transmission oil a few times this weekend. The fluid, while not bad, does not look as pristine as the power steering fluid. Also, 2000 miles after the engine oil change, the oil looks a bit dark. How dark does your engine oil get after a few thousand miles?
