New GM power steering fluid

[Stu_Rock]

I picked up some GM PSF for some flushes I need to do. It has the new part number 89021182 (instead of 89020661) and is in funny-shaped bottles. According to the MSDS, it's made by Imperial Oil (a.k.a ExxonMobil Canada a.k.a. Esso Canada): http://paceperformance.com/attachment/36210-.pdf The bottles indicate Canadian origin, which is consistent. Here's the datasheet for the Esso-branded fluid: http://www.imperialoil.ca/Canada-English/Files/Products_Lubes/IOCAENPVLESPSF.pdf I got this stuff from AutoPartsExpress shipped for a per-quart cost cheaper than buying Valvoline locally. Finally, pictures:

I did some more investigating, and the bottle design is owned by Gold Eagle. You can see the same bottle on Gold Eagle's website: http://www.goldeagle.com/products/product2F1D.aspx Amazon's listing for Gold Eagle power steering fluid indicates it has a price comparable to GM's list price of $9.81/qt: http://www.amazon.com/Gold-Eagle-21303-Universal-Steering/dp/B000SR4O66 Is the Gold Eagle product the same thing as the GM product, or is Gold Eagle bottling Exxon fluid for GM? Hard to say. In any case, I did two flushes with this stuff yesterday. I had stored the bottles in my garage, so the fluid was cold. It had low viscosity compared to STP or Valvoline, so it seems like it might be pretty good stuff.
