All I run is E85. It didnt require anything special tuning wise.

Why E85?

Performance and cost. Been running it 100% for over 3 yrs now

You're also supporting American farmers and not people who want to kill us. I wish I could run it, but the mods dictate otherwise. Something about superchargers and detonation and boom.

Did you compare 93 octane to E85?

How so? Nothing substantiated with numbers

I have never tried E85. I read that it get less mpg so I only run 93. Just wondering why you are only using it? Thanks

[RyanbabZ71]

Yea I get less MPG but I basically break even with the cost difference/milage loss.

[ChevyTech77]

Which is weird because every time that I've run E85 vs premium I always loose out big money spent, wise. I loose 3-4 mpg on ethanol It would take over a $1.00 difference in price to break even and ethanol is rarely more than .$60 a gallon cheaper than premium here. Not to mention, there is only one pump in my area and 0 up north where I usually travel.

[MikeNH]

I figured about 75 cents/gallon was needed for me to break even and as of late it has been around that in the Jackson area. Ann Arbor has an even bigger cost advantage but I'm not out there too often and I'm not driving 80 miles round trip for gas.

At the station by my house that has it, E85 is 3.13 where 93 is or was 3.79. I remember reading somewhere about a guy tunning his 6.2 on E85 and was maintaining his mileage in the mid 16's. (but cant remember who or which forum i read it on)

So if you were to tune specifically for it and pull down mid 16's it would easily be worth it. Everyone that runs it seems to love how their truck perform with it.

Plus comparing it to 87 there isnt much of a cost difference but compaing it to 93 there is a pretty substantial difference.

Just to throw my math out here.......

 

15,000 miles last year driven.

 

Averaged 14 mpg over that mileage on premium.

 

15,000 / 14 = 1,072 gallons of fuel (I rounded up).

 

Premium here averaged $4 a gallon last year.

 

1,072 gallons at $4 a gallon would cost $4,288

 

Averaged 11 mpg on E-85

 

15,000 / 11 = 1,364 gallons of ethanol.

 

Ethanol averaged $3.40 a gallon here last year.

 

1,364 gallons at $3.40 a gallon would cost $4,637.60.

 

$4,637.60 / 1072 = $4.33 a gallon.

 

So, premium, would have to be $4.33 a gallon, with ethanol staying at $3.40 a gallon, for me to break even. I've never seen premium take a significate spike in price without ethanol following it, in my area. Premium is currently $4 a gallon here. Ethanol is currently $3.35.

 

I'll continue to run premium.

E85 has been runnin 2.50 - 2.90 here the last month. Makes me

I've never seen it under $3.29 a gallon around here, in the past 3 years.

[RyanbabZ71]

Lowest I have paid has been $2.29. I have 4 stations all within about 5 miles here

[BlueZ01]

Has anyone put a programmer on the 6.2? If so which one and how do you like it? Extra HP extra mileage?

[VMaxtastic]

I'll be tuning mine with BlackBear... Just breaking it in a bit first. I got em to do a tune for my 07 Vmax and it was quite beastly after.
