Loving my E85 right now

[Dustin Jackson]

First tank of E85 I went 214 miles using 19.01 gallons which is about 11.2mpg. Pretty good considering my “average MPG” on the cluster was 13.7mpg.

Just filled up again, drove 195.8 miles using 18.27 gallon of gas comes out to about 10mpg

Then it must actually be 85% Ethanol instead of the "minimum 50% to maybe somewhere in the 70s but likely 60s percentiles" like everyone else sells. I'm gonna make it a point to get out to that Chevron where I saw this to see if they have the same.

@iamdub Ill keep you posted if the button continues to change depending on the batch of E85 they are selling, that’s pretty cool they did that if that’s the case

E85 will only get to 83% as the other 2 percent are chemicals so it will not be palatable. E85 can be anywhere from 51% to 83%.

@Dustin Jackson You're doing pretty good on it, mine averages 11.7 mpg between city and highway use on E85.

Dammit! I was looking to save some money on vodka.

I thought that's why the 15% gasoline was in the mix.

You're making too much sense for Washington!

I went by that Chevron today and they cut out E85 altogether. Maybe they just let the RaceTrac across the street be the sole local provider for it. They've replaced it with Ethanol Free 87 ("Not a Chevron Product").

Good deal!

I am defrosting the Tahoe in the morning now that it is cold I am down to 9.85mpg

For those of you who are running E85 almost 100% of the time are you guys adding any fuel additives?

Something like this:

I ask because I've been running E85 pretty consistently for over a year (in that time frame maybe 4-5 tanks of 93). I have experienced a few symptoms specifically on start up during the winter and colder mornings here in Ohio.

 

[Marky Dissod]

'E85', mathematically, is never E85.
In the summer, it can be as much as 83% ethanol.
In the winter, it can be as little as 51% ethanol.

I wonder how the gasoline additives behave in varying proportions of ethanol?

Good deal!

I've been running it exclusively for about a year now. I'll pour a can of Berryman's B12 in every couple of months when I think about it just for the hell of it. Hard starts/extended cranking and rougher cold start idle are normal with E85 in cold weather. We don't have enough cold weather here for that to even be a factor. My E85 sources here are consistently ~62-65% actual alcohol content.

Don't need the additives. Hard start in cold weather is normal with E85. It's not due to a problem with the fuel or your car, just the nature of the beast (E85).

Mine will do it on the first remote start when it is in the 50s or colder but not the second.

If yours performs worse, you might think about diluting the E85 with some gasoline, like 50/50, 60/40, whatever.

I have not noticed any hard starts in the north on E85.

I’ve been running exclusively E85 for several months now. I bought a small tester kit and keep it in the glovebox. My local Speedway station E85 tests at 80%!

I did notice a little over 15% decrease in fuel mileage, but I had my 5.3 professionally tuned for both fuel maps.

What seems to kill my gauge-reported fuel mileage reading is remote starting and letting the vehicle idle, lol.

I’m in the upper midwest and only noticed the longer start crank with the first tankful. The advanced timing maps on E85 can make it take some extra spins to start in cold weather.

I love the fact that I’m not carbon-ing up my intake passages or valves.
