Here is asummary of MSDS data plus other information I have gathered on forums. The MSDS shows max and min values for ingredients but I have also included what I think is a good guess for the actual percentage based on some math and logic. The Schaeffer's stuff is clearly different stuff so I didn't attempt to rank it relative to the others. The others are ranked based again on logic and opinion where PEA content is the top priority. I also gave preference to cleaners with a diversity of cleaning agents. Some of these clearly do not add up to 100%. Redline SI-1 and Amsoil PI probably have an ester based lubricant as the final ingredient so they are a cleaner and upper cylinder lubricant. I was surprised by the quality of both the 3M product and the Slick 50 product. The 3M product "probably" has the highest PEA content. The Slick 50 wins the contest for the most cleaning agents. BG 44K is an odd one. I "guessed" that the missing ingredient was PEA. But it is hard to estimate the percentage. However, I doubt it is more than 40% and most likely closer to 33%. Not really all that impressive for the price. If the PEA content is the optimistic guess then it comes in at #2. If not, it comes in much lower at #6.
