MMO has a boiling point of ~170F (depending on which MSDS is correct) so dilute your engine oil with MMO and what happens? When the engine reaches normal operating temperatures, MMO boils off and is gone. Probably leaves some residual trace contamination in the oil. So when one hears a claim that MMO provides long term engine protection between oil changes (and the reality suggests it exits the engine breather or exhaust pipe in the first 15 min. of engine operation), some skepticism about that claim may be warranted. Perhaps another marvelous "mystery" ingredient suspends the laws of physics.....? I dunno.
Another issue, MMO flash point is close to kerosene. So mixed in with fuel at the ratio of 1-2 oz per gallon, or roughly 100:1, perhaps slows down the combustion process by 1/1,000,000 of a second? That makes the engine run noticeable smoother, cooler, more power, etc.? Really? And since it quickly burns up during the combustion process, not sure what hangs around to "lubricate" upper cylinder components. Seems like whatever function MMO claims to provide as a fuel additive could be duplicated close enough with kerosene or diesel. Regulating bodies will classify it as fuel contamination but what the hey.
The credibility of 99% of MMO testimonials rank right up there with the urban legend about the car with a 50mpg carburetor. We wanna believe it's true......and it's tough getting through the initial denial stage. Kinda like when reality convinces a kid the easter bunny, tooth fairy and santa clause are not real even though his parents perpetuated this myth for the first several yrs of his life. It's tough to let go.
