I run the least expensive 87 octane gas with 15% alcohol that I can find in my neighborhood on Long Island. My Coupe, which needs refreshing (restored in 1980) has gasoline in it that is several years old, an it starts right away. The is no additive in its gasoline and there is no separation that I can see.
I am not a believer in using gas tank sealer, add-on gasoline filters, and additives of any kind in the gasoline and motor oil used in my Model A's. I cannot recall ever having a gasoline issue.
