I'm new to the board and apologize if this has been covered elsewhere in the forum; I searched around but could not find anything specifically.
I'm no motor oil expert and need to determine whether two marine oils are functionally equivalent (or at least similar), in the view of folks who know more about oils than I do.
Would anyone be wiling to take a look at the PDS data that I have extracted below for each of the two products, and let me know your quick thoughts? It seems to me that given the sizable differences in viscosity, flash points, and ash content, that these are NOT comparable marine oils--but like I said I'm new to the board and to motor oils, so I could be overblowing the differences in those attributes. I don't want to make this about brands but if the brand names/product names are needed to answer the question, I can certainly provide them.
Thank you very much!
