Read below. Kind of long, but a lot of the ingredients are similar between fuel injector cleaners and lacquer thinner.

From Bob is the Oil Guy, followed by ingredients of lacquer thinner.

Bob:
MSDS data:

Techron Concentrate
Distillates, hydrotreated light < 50 %weight Aka: Paint thinner(oil based)
Stoddard solvent < 35 %weight Aka: dry clean solvent, white solvent
Solvent naphtha, light aromatic 5 - 10 %weight : zippo lighter fluid
Benzene, 1,2,4-trimethyl- 95-63-6 1 - 5 %weight : powerful toxic solvent
Xylene , powerful solvent

Techron is naptha and 3 kinds of benenze.
---------------------------------------------------------------------
GUM OUT INJECTOR CLEANER (WINTER GRADE)

Chemical Percent
Trade secret or proprietary formula < 1 ( secret #1)
Petroleum distillate(s) (unspecified) 40-70 ( most likely paint thinner)
Detergent/Inhibitor mixture 1-10 ( secret #2 )
Isopropanol 30-50 (rubbing alcohol, GAS DRYER "CH3CHOHCH3")

I can not begin to guess why we need more alcohol when all gas has it already.
Gasoline, must contain 2% oxygen by weight, in most smog chocked areas of the USA.

---------------------------------------------------------------------
Seafoam ingredients:
1 PALE OIL 4229 40-60% = A base or process oil refined until its color = yellow.
2 NAPHTHA 20 25-35% solvent powerful , common in all good injector cleaners. Zippo juice !
3 IPA 125 10-20% = Isopropyl Alcohol (rubbing alcohol), Useless in gas , cuz it already has tons.

in my opinion , putting oil into your gasoline is not too smart. Think about it? fouls plugs, makes lots of carbon , and messes up OXy sensors. You decide.
---------------------------------------------------------------------
"GM TEC" ingredients:

2-BUTOXYETHANOL, a paint and ink solvent , used even in Clorox cleaner 409
Naptha, , raises octane rating of gas, , simular to Zippo ligher fluid. Coleman camp fuel.
4-METHYL-2-PENTANOL, (aka:Methyl isobutyl carbinol) used as a lacquer paint tinner
9-OCTADECENDIC ACID.(aka:Oleic acid, found in Olive oil) ( this acid is interesting)
---------------------------------------------------------------------
BG-44k: ( madly popular but little different than old Chevron Techron)

Light Aromatic Solvent Naphtha , ( Zippo lighter fluid)

1, 2, 4-Trimethylbenzene , commonly found in up to 7% by volume already in Gasoline.

Xylene ,(1,2-dimethylbenzene & 1,3-dimethylbenzene & 1,4-dimethylbenzene), xylol , powerful solvent

Cumene ,(isopropylbenzene, ) powerful solvent,raises octane of gasoline.
---------------------------------------------------------------------
GUNK , RADIATOR SPECIALTY COMPANY, FUEL INJECTION AIR INTAKE CLEANER
2-Propanone 30-60 % aka: Acetone
Ethylbenzene >10 % a powerful solvent
Hydrotreated Heavy Paraffinic Distillate 1-10 % weak solvent
Methanol 1-4% , solvent.
Propane 10-30% , gas
Toluene 15-45% ,powerful solvent
Xylene (mixed isomers) 5-20%
---------------------------------------------------------------------
Red Line SI-1
1-5% Alkenylamine - (a detergent ,even used sometimes,in baby shampoo)
1-10% Isoctanol - ( C8H18O , aka, 2-ethylhexan-1-ol, or Octyl alcohol)
1-10% 1,2,4 Trimethylbenzene , (C9H12 )
5-20% Aliphactic Napthta , zippo lighter fluid. , aka: white gas, low octane)
--------------------------------

Valvoline Complete Fuel System Cleaner
52 - 62% Kersosene
28-38% Light hydrotreated petroleum distillate
6-16% Stoddard Solvent ( stoddard is the name of the man who invented dry cleaning)

Warning, some of the chemical names have 20-30 synonyms."

Good info but I still won't put that canned **** in my gas tank.

 

MY POINT EXACTLY... to those who have never used it, and don t even know whats in it, and yet know all about it, I say... don t use it... I don t really care.. I know it works as do all who have actually tried it, and not just speculated....I do recommend the #1 or fast thinner it cleans better..
