Naphthenic Hydrocarbons, Mineral Spirits, Chlorinated Hydrocarbons.
Can someone tell me what these are, and what their purpose is?
I might use some in my brother's car, was just curious as to what these ingredients are.
I noticed that if you get a small amount on your hands it smells like a certain brand of mint flavored candy I used to eat as a kid back in the 70's. I can't remember the name of the candy.
No mystery to the MMO smell: oil of wintergreen. As hokey as it may sound that stuff is a very aggressive cleaner. It is good for freeing stuck mechanisms at room temperature. I really like it for stiff and neglected door hinges. As for what happens to wintergreen oil in the crankcase or combustion chamber I can't say.
