I went to a few places today to ask for Castrol GT PS Fluid...every place I went to...the kid pulled Dexron-Mercon III off the shelf...and I shook my head and educated them...the owners of the shops stood by the employee...Finally I drove 45 miles today to a Canadian guy who brings parts from Montreal here...and bought 6 bottles of this stuff. Its been sitting on the shelf so long, the bottles have yellowed.
