Did I use the wrong PSF (Dexron II not Dexron III)???

Hmmm.... I confess ... I don't know ANYTHING about Power Steering Fluids ...
I looked up Red Line D4 PSF and found there are multiple types of RedLine ATF but, to me, they all seem to do just about the same thing! I'm confused.

The Red Line PSF bottle I bought for $12/quart is labeled "Red Line Synthethic Oil Power Steering Fluid" which meets Dexron, Dexron II-D, Dexron II-E, Ford Type-F, Mercon, & M2C138-CJ requirements. Also satisfies API 75W GL-4 Gear Requirements.

Wow, most of that is alphabet soup to me!

Digging a bit, I ran into a nice E46 power steering R&R DIY here and I do see some people use Mobil 1 PSF here but most seem to say almost any ATF fluid will work, as in here.

Oddly, there's nothing about which power steering fluid in the E39 wiki but luckily I found this really good article about changing your Power Steering Fluid in the E39 here which says any ATF that meets Dexron III standards will do for our BMWs.

Oh, oh. The Red Line Power Steering Fluid I bought is apparently only Dexron II. Did I use the wrong PSF ???
