Dhurley so since the color thats leaking is the greenish color I SHOULD stick with Pentosin CHF 11S???
I would look in your owners manual for the power steering fluid spec that it should be. Spec 236.3 is ATF. Spec 345.0 is CHF. Then buy a cheap turkey baster and remove a little bit of power steering fluid to see what the color truly is. I just took this picture in my garage. Both fluids are new genuine MBZ and wiped on to a clean paper towel. CHF is a dark green in the bottle, but light green when wiped on a towel.
345.0 MBZ CHF 11S on the left, 236.3 MBZ ATF on the right.

Are you positive about Pentosin not mixing with ATF? I think the reason I made that assumption was that I have been mixing Pentosin with MB Fluid for a couple years now. So... if ATF can be mixed with MB Fluid and Pentosin can be mixed with MB Fluid... then doesn't that mean that Pentosin can be mixed with ATF?
MB 236.3 ATF is your standard Dex 3. People in the BMW and Porsche world have complained for years that CHF and ATF will eat seals and hoses when mistakenly mixed together. CHF is also a much thinner viscosity and a popular choice in cold climates.
