Pennzoil Gumout Regane
60-70% kerosene
30-40 Polyether amine
Analysis: I don't see anything in them that would harm a car
Gumout Xtra
90-95% kerosene
5-10% detergent
Analysis: I don't see anything in them that would harm a car
Chevron Techron:
30-50% hydrotreated petroleum distillates
10-25% Stoddard Solvent (similar to kerosene)
5-10% Naptha
1-5% Benzene
.1-.5% Xylene
Analysis: Naptha, Benzene, and Xylene are strong solvents, but I do not believe they are used in enough volume to cause problems.
Valvoline Complete Fuel System Cleaner:
52 - 62% Kersosene
28-38% Light hydrotreated petroleum distillate
6-16% Stoddard Solvent
Analysis: A good formula, should have no negative affects on seals, similar to Techron but without the stronger solvents.
Amsoil Performance Improver
80% petroleum distillates
No other compounds identified
Analysis: Safe, but without full disclosure of any other compounds, one must reserve judgement against the other, more technically advanced cleaners like Techron and Red Line SI-1.
Red Line SI-1
1-5% Alkenylamine
1-10% Isoctanol
1-10% 1,2,4 Trimethylbenzene
5-20% Aliphactic Napthta
Analysis: A very complete formulation: detergent/dispersant, corrosion inhibitor, fuel additive. It has an alcohol which will help disperse any water, several strong solvent cleaners, and a detergent. Very comparable to Techron, perhaps a bit stronger, so be sure to use it full strength only when properly titrated, or in smaller amounts for continuous cleaning
PEA is what's in Gumout Regane. Nice stuff. It was in BG44K until about November when it was removed.
