From the VOA analysis shown for the BMW VOA in the pdf, this cannot be the Pentosin fluid I mentioned earlier: The fluid in the VOA is a 75W90.
As I recall it is another Low Viscosity MTF with a 100C vis of around 5.9 cSt, and similar to the BMW (Pentosin) MTF-LT-3
In the analysis shown in the VOA pdf it is stated as, "BMW MTF L-4" which I assume was the exact nonmenclature on the bottle?
Notice, the Pentosin fluids state, "MTF-LT-X." The VOA analysis says "L-4."
Again, what fluid was shown in "2009 JCW CLUB-TR" UOA pdf? Was this the factory fill? The fluid shown here would be very similar to the Pentosin MTF-LT-3 or a 70W80 or thereabouts.
Bottom line: I don't think the fluid shown in UOA was the BMW MTF L-4 as I have never seen a 75W90 shear down to 7.x cSt.
Another question: How many miles on the transmission and how many miles on the fluid shown in the UOA?
