Here is a picture of 3 syringes of PS fluid. 1 is new fluid sucked out of a new bottle, 1 is fluid which has been in service since 9.15.15, (2 years plus a week, sucked out about an hour ago), and 1 is the fluid I drained from OEM? (when I bought the car it was 12 yrs old and 57K on it). Guess which fluid is which...
BTW, when I did the new fluid on 9.15.15, I jacked the front wheels off the ground, disconnected the return hose and had my daughter crank the steering wheel lock to lock (motor off) with me under the car until all fluid quit spurting out, then refilled the system with almost 20 oz (in a system that the FSM says holds 16 oz). Judging from this pic, I see no reason to change my 2 year old fluid...Although my curiosity is now piqued and I may do UOA on the OEM? fluid just to see how nasty it is?
To the OP: If you're considering transmission fluid service on a vehicle with 130K on it, you may find this worth a read...http://www.agcoauto.com/content/news/p2_articleid/238
I’m gonna guess far right is oem fluid, middle is used fluid and left is new fluid but I might be wrong.
You are correct sir. It was dusk outside and I needed a flashlight to illuminate the picture, but what I think I just learned is that my 2 year old fluid is fine. It is not nearly opaque.
