I don't have 93oct so i run 91oct and 3 gallons of E85 to bump my 91 to 93 and it's been driving great! I wouldn't get on it and bring the car to redline too much on map2 or higher without a higher octane like 96+ but for normal driving and pushing it here and there we should be fine

Is there a chart anywhere that tells me what 3 gallons of E85 does to total octane level with 17 gallons of 93 octane premium? thanks.

You can use this chart below as well, i usually change the e85 octane to 105 since it's supposed to be anywhere from say 102-108 so i go right about middle at 105 on the chart. 3 gallons with 17 of 91 nets you 93.1oct, with 93oct 3 gallons would put you at right about 95oct. I would not exceed 3 gallons of E85 as it is a different viscosity than regular gasoline and the pumps have to work harder to move it is my understanding of it.
