AVOID all Gas Additives & Fuel System Treatment Products that contain alcohol

and/or attract or absorb water with E10 gasoline.

Products that contain strong solvents and emulsifiers should also be avoided with E10.

Carefully review ALL ingredients of fuel treatment products before use in E10 gas.

Avoid gas additives and fuel system treatment products that:

Are water soluble. Terms "hygroscopic" and "miscible" describe the ability to attract and absorb water.
Are listed as "not compatible with strong oxidizing agents or alcohol".
Claim they will stop phase separation or remove water - Impossible, if any ingredient existed that removes all water it would already be in all gasoline sold.
False claims that product will "prevent, fix repair and/or reverse" all ethanol-related fuel problems. No such miracle products exist.
In high risk situations, certain additives will offer some benefits with E10. Ignore the marketing slogans and focus on whether or not the ingredients listed will help with the specific problems you are having. No retail product will remove water. Many products just contain solvents and cleansers.

Since ethanol is a very strong solvent and cleanser, use of additional gas additives with E10 is often unnecessary.

Following simple precautions should be enough to safely manage E10 in most (newer) engines, while replacing fresh gas every 2-3 weeks.

Learn the names of alcohols to avoid using fuel additives containing alcohol in E10 gasoline.

COMMMON NAMES OF ALCOHOLS:

Isopropanol Alcohols: 1-Methylethanol, 2-Hydroxypropane, 2-Propanol, 2-Propyl alcohol, Dimethylcarbinol, Isopropyl alcohol...

Names of chemicals similar to ethanol: 2-Butoxyethanol, Butoxyethanol, Butyl cellosolve, 2-butoxy- Ethylene glycol, mono-n-butyl ether, Ethylene glycol monobutyl ether, Monobutyl ethylene glycol ether, n-Butoxyethanol...

NOTES

Information contained in above chart primarily obtained from product manufacturer official MSDS and product literature.

If you believe any information is inaccurate send documentation to fuel.testers@yahoo.com

General Comments: The brand of gasoline and type of engine should always be considered when choosing to use any gas additive product.

Gasoline already contains many of the same ingredients used in many fuel additive/gas treatment products.

- Often the 10% ethanol in E10 replaces the need for any additional fuel system cleansing agents or solvents. -

The information listed on the products above is solely to inform you which products contain alcohol and or attract/absorb water so you are better informed to chose an appropriate E10 additve, when necessary -

Over the years we have received numerous reports from consumers who have experienced engine damage from contaminated (E10) gasoline. There are many varied reasons for actual cause of damage, including poor quality gasoline, improper E10 fuel management, misuse of gas additives. and more...

We chose to refrain from recommending any specific products, since engine details and use are necessary in choosing an appropriate additive or not, but we wish to state:

Warning: Because we have received so many reports of gas problems from consumers who have used either K100 or Ezorb, we feel obligated to mention this here. Our conclusion that these 2 products are contraindicated for use in E10 gasoline is based on a large number of consumer reports and information contained on company's website and MSDS, when available.

There are several other products listed in chart above that we believe are contraindicated for use in E10 fuel (based on ingredients) - We will add them to our warning list if and when we receive many reports from consumers who believe additive was primary/sole cause for problem.

Hint: You do NOT want to force excess water back into gas; You do NOT want to add ethanol alcohol to manage E10 side effects;

Strong emulsifiers will not only force alcohol/water back into petroleum gas, they may also solidify engine lubricating oils and gasoline ingredients, causing clogging, gelling and gunk throughout the engine.

Notes:

(1) Shellsol is an industrial solvent chemical found in many products. Shellsol D60 chemical name = Solvent Naphtha (Petroleum) Medium Aliphatic. Shellsol is a registered trademark of Shell.

(2) Seafoam MSDS lists "IPA" under ingredients. The only commonly used term for abreviation IPA =Isopropyl Alcohol. Isopropyl alcohol is soluble in water. Seafoam Sales Company did not respond to our request for more information.
