Good thread.

70% Light Aromatic Oil (Pale Oil)
- It is a Naphthenic Oil, so while it oxidizes faster than a Paraffinic oil, it does clean and dissolve sludge and carbon well and cleans up after itself from any oxidation. serves as base oil as well. [Naphthenic oils have more solvency and are more polar (they are attracted to metal more), but oxidize faster.

29% Mineral Spirits
- Cleans Varnish very well. General cleaner. Also acts as an antioxidant.

38 parts per million (ppm) Boron
- AW/EP agent, friction reducer, antioxidant

900 ppm Phosporous
- AW/EP agent

1/2% 1, 2 ortho-Dichlorobenzene
- EP agent as it interacts with Iron to form an Iron chloride barrier under any ZDDP or other AW additives. Also very good cleaner/solvent, and friction reducer

1/4% 1, 4 para-Dichlorobenzene
- EP agent as it interacts with Iron to form an Iron chloride barrier under any ZDDP or other AW additives. Also very good cleaner/solvent, and friction reducer

Oil of wintergreen - for the scent
- Not just for the cent, is also a cleaner. may aid lubricity.

Red Dye - for the color
- well this one just colors the stuff

I have never done an injector cleaning on any of over 150 cars I have owned. But then I never had any problems that were related to injectors. So I guess as someone says, I must be doing something right, right? To me injector cleaning, if you dont have injector problems, is like Tiger Powder.
I sprinkle Tiger Powder all around my yard here in South Texas and I have never seen a Tiger in my yard. I have seen Jaguarundi and Chupacabra. But I haven seen powder for those breeds. Must be doing some good, right?

You’ve owned more than 150 cars? Typo?
