Anyone running E85 in their 6.0?

Anyone running E85 in their 6.0?

Postby stretchssilverado [OP] » Aug 23 2012, 4:25am

My 2012 2500HD is a flex fuel vehicle, and was curious if anyone else with this has tried putting e85 in the tank. I know I will lose gas mileage by runnning e85, but might make a few more hp's but really just wondering if anyone was brave enough to try it yet.

If I'm not mistaken I think you lose horse power as well with ethanol.

I thought you gained power with ethanol. I see a lot of people with engines built running it cause they can add more timing. I ran it threw my 5.3 and it seemed to have more power. Lost 3-4 mpg but at the time E85 was 3.14 and gas was 4.40. So I saved some money.

Yes. you gain HP because E85 is about 95 octane. But ethanol has less engery than gaoline so you lose mileage.

Although GM Powertrain does not show any gain in the 6.0L L96....

I am going to experiment. Gonna use half e 85 and half 87 octane and check mileage against using total 87 octane and against using total e 85. It will take a while to draw a conclusion but its an experiment.

From my understanding you need to run the tank almost empty before putting e85 in. That way the computer can adjust properly other wise you might have a issue with the way it runs.

You may be right but I have an 08 Impala with Flex Fuel, I have mixed it at times when the price was right and never worried about being almost empty. The DIC will show less gas mileage over time but the engine runs just as good as ever. i use the idea of a 15 to 20 % loss in mileage, so the price needs to be 15 to 20 % less to justify the E 85. It don't happen often.

from owners manual...................................

Fuel E85 (85% Ethanol)
Vehicles that have a FlexFuel badge
and a yellow fuel cap can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
For all other vehicles, use only the
unleaded gasoline described under
Recommended Fuel on page 9‑74.
We encourage the use of E85 in
vehicles that are designed to use it.
The ethanol in E85 is a “renewable”
fuel, meaning it is made from
renewable sources such as corn
and other crops.

Many service stations will not have
an 85% ethanol fuel (E85) pump
available. The U.S. Department of
Energy has an alternative fuels
website (www.afdc.energy.gov/afdc/
locator/stations/) that can help you
find E85 fuel. Those stations that do
have E85 should have a label
indicating ethanol content. Do not
use the fuel if the ethanol content is
greater than 85%.

At a minimum, E85 should meet
ASTM Specification D 5798 or
CGSB Specification 3.512. Filling
the tank with fuel mixtures that do
not meet ASTM or CGSB
specifications can affect driveability
and could cause the malfunction
indicator lamp to come on. As the
outside temperature approaches
freezing, ethanol fuel distributors
should supply winter grade ethanol,
the same as with unleaded
gasoline. Winter grade blends
typically do not exceed 70%
ethanol (E70).

The starting characteristics of
ethanol make it more difficult to start
below 0°C (32°F), which may lead
to longer start/crank times. Engine
start on ethanol fuels down to
−30°C (−20°F) is possible,
provided a winter grade ethanol
blend is used.

It is best not to alternate repeatedly
between gasoline and E85. If you
do switch fuels, it is recommended
that you add as much fuel as
possible — do not add less than
11 L (3 gal) when refueling. You
should drive the vehicle immediately
after refueling for at least 11 km
(7 mi) to allow the vehicle to adapt
to the change in ethanol
concentration.


E85 has less energy per liter
(gallon) than gasoline, so you will
need to refill the fuel tank more
often when using E85 than when
you are using gasoline. See Filling
the Tank on page 9‑77.
Notice: Some additives are not
compatible with E85 fuel and can
harm the vehicle's fuel system.
Do not add anything to E85.
Damage caused by additives
would not be covered by the
vehicle warranty.

The ECM has a sensor that determines the alcohol content of the incoming fuel (if you have a way to read it).
