The Differences Between Ethanol and Gasoline. 1  A gallon of gasoline provides one-third more energy than a gallon of ethanol.  Blending ethanol and gasoline at a ratio of 85 percent to 15 percent (E85), the blended fuel is nearly thirty percent less powerful than pure gasoline. Ethanol is similar in acceleration, power, and cruising ability, but ethanol miles per gallon are less than pure gasoline.
A. I have been etching stainless steel for over 30 years. The etchant is ferric chloride, temp 130 Â°F. around 37 baume works best. Etch rate is about 1.25 mil per minute in an oscillating spray etch. Stainless does not pit in ferric chloride unless you rinse with water and then etch more.
