				 Ethanol in Fuel 
 Quick question for the group. Do you run ethanol free gas or does it matter. This would be for a 427 ERA with a 427 FE Shelby aluminum block and aluminum heads, normally aspirated and carborated car. In my area I can find ethanol free 90 octane, but cannot find ethanol free 93 octane around. Your expertise and experiences are much appreciated. |
