MIXING E85
 

Does anyone know if you can mix Ethenal with pump gas e85 to raise the eth. level? right now its all winter blend (78%) i would like to stick with true e85 or a little more if possible.

If I could get E98 I would run it instead of E85, unless price was a big factor. However the answer is yes, E98 can be blended to bring the levels back up. Just do not mix leaded fuel or any metallic fuel additives to ethanol, makes the knock rating go down.
