so I know this is old but I am not finding this topic covered with my specific questions answered, Ford used to say never to run Mercon V in a Mercon equipped transmission then one day poof it was backward compatible which is against the tsb from before.
With the trend towards lighter fluids, I had always assumed Mercon v went to a lighter base stock ie I higher grade as well. But searching on the various Mercon/dexron II fluids they seem to hover around 7.1-7.3 cst @ 100 and 34-35 cst@40. However, I cannot find a ford pds on the original Mercon M2C185-A.
The Mercon V 7.5cst@100 and 33.2@40, so it would seem the opposite that it's indeed heavier?
So does anyone have any hard data comparing the two and maybe some actual pds from the actual Motorcraft Mercon? What are the differences between these two besides viscosity?
