Here is the real composition of MMO (as best as has been discovered through oil analysis) and MSDS filings - not all the heresay we always get:
70% Light Aromatic Oil (Pale Oil)
29% Mineral Spirits
38 parts per million (ppm) Boron
900 ppm Phosporous
1/2% 1, 2 ortho-Dichlorobenzene
1/4% 1, 4 para-Dichlorobenzene
Oil of wintergreen - for the scent
Red Dye - for the color
MMO is so vilified around here by so many that do not even accurately understand what it is - granted, it is hard to get details on it, so here it is, for better or worse.
For my two cents, I have used it for some time in the fuel and it works great to give the engine pep, clean things up over time (not designed to be a one-time cleaner), and to keep things well protected/lubricated.
As for use in the oil, I am not totally adverse to this in small quantities (1/2 quart per oil change, not the full quart they recommend), but prefer LC20 and use it regularly in all my vehicles.
Easy killa! I don't know why anyone should be impressed with the results of this analysis. I mean, it's cool that someone did an analysis. But the MSDS is nothing new. It's been widely discussed for years on here. The boron and phosphorus is certainly a nice little surprise. I have to say I AM impressed with that one part. But it's not like they or any other exotic compound are doing the cleaning. It's the stoddard solvent and di-chlorobenzene that are doing that. I can report that I used the "substitute for a quart of oil" method all the time in the crankcase of my old Probe. I don't guess it hurt but I don't know that it did anything either.
What I'd like to know while we have the great Mola watching this thread, and forgive me if this is a stupid question, is why is there phosphorus even though there is boron present? I thought the phosphorus was the real booger in zddp? Why would you toss the zinc and leave the phosphorus?
