Refilling e85

n54SQUAD · 04-25-2015, 01:38 PM

So, quick question. So im just about to finish my 1st Tank running 4 Gallons of e85 to a full tank, and was wondering if i were to fill up again to another full tank. what would be the ratio to get around e30 again, i have a quarter tank left.

Get the E85 Mix Calculator app. worth the $1 or whatever it is.

The E85 mix calculator app will become your best friend. You need around 3.2 gallons of E85 for a 30% mix.

I see you're putting in 10% ethanol content for 93 octane as well. I wonder how often 93 pump has 10% e in it. Are we all just assuming this is correct?

You can always get an ethanol tester. I know Steve from Fuel-It has them if you want to be certain.

E30 is easy. However many gallons you're filling up, 1/4 of those should be E85 and the rest E10. Assuming you're starting with E30 of course.

Our tank is 15.9 gallons including the reserve right ? I usually pump 4.2 gallons of e85 on a nearly empty tank. If gets confusing when there is fuel still left
