Q&A for How to Remove Ethanol from Gas

E85 or 85% Ethanol (highest amount of ethanol sold in large quantities in the United States) can hurt the performance of your motor if it is not specifically designed for it. The best way to tell is if your fuel cap is yellow. However, most gasoline sold in America is regulated at E10 or 10% ethanol and has been that way since 2008 (unless specifically designated rec fuel). Your factory fuel lines and injectors are able to withstand that amount of ethanol as it doesn't have a terribly large effect of the stoichiometric ratio at which it burns (i.e., E 10 Stoich AFR = 14.1 versus pure gasoline, which is around 14.7).

Some mechanic shops have safe containers for disposing of gas and oil. Autozone stores (among others) offer free disposal of fuels and oil. Avoid pouring them into the general environment.

All liquid fuels should be properly stored or taken to a safe disposal place such as an auto parts store or a mechanics shop.

Probably not. It might even improve perfomance and help keep an engine running longer. Just be aware of the possibility of the fuel pump getting clogged.
