MPG Increase - Non-Ethanol Gas - What to Expect?
My wife, son and myself will be taking a road trip from MA to TN this weekend for a total of 920 miles each way. I'm making it a point to only fill up with ethanol free gas and I'm wondering how much my mpg will increase.
We're driving in her 08 Nissan Versa SL Hatchback with CVT. Normal highway without applying any hypermiling techniques is 35mpg.
How many mpg do you think I will gain? I know someone is dying to tell me ethanol has 90% the energy of gas so a gallon of E10 has 98% the energy of real gas, etc. I'm looking for some real world advice, not btu calculations!
Thanks!!!!  |

Hi Mightymouse13:
Most likely about 2% although in some rare instances, some receive upwards of 6 + % for some unknown reason. Ignition timing is not the answer here either.

The change in your mileage under otherwise identical conditions should be close to proportionate to the difference in energy content per gallon, which is about 3%. So, 35mpg/.97=36.1, theoretically. You'll probably actually get some other number, due to uncontrolled variables. |

Re: MPG Increase - Non-Ethanol Gas - What to Expect?
I did something similar in my 98 GMC K1500. last year I drove down to Daytona for Bike Week, and got 16 MPG on E10. I made the same trip this year, making sure I only purchased ethanol free, and averaged 18 MPG. That's a 2 MPG difference on a V-8 4wd pickup truck with one ton of weight in it. My Escape Hybrid gets about 6 MPG better on E0 than E10. I'm guessing the Versa will be 3-5 MPG difference on the highway.

Everybody go to pure-gas.org for the growing number of addresses, details, & great zoomable map to the minority of 5300 stations(11 in every 350) that sell 100% pure gasoline in the U.S. & Canada. With accurate 'before & after' line-graph records, our 3 cars' mpg increased 8+%, 7-8% & 5%. All engines were smoother, quieter, & needed less downshifting to ascend hills.
For-ethanol designed engines(with much higher compression ratios than gasoline engines) get their best efficiency using 100% ethanol(duh). Gasoline engines get their best efficiency using 100% gasoline(more duh).

No, he's starting with E10 and going to E0.

Re: MPG Increase - Non-Ethanol Gas - What to Expect?
This topic makes me want to ask if Premium grade (91-93) has less ethanol than does Regular 87 E10. Anyone know what the industry does? Numerous posts on the subject still leave me wondering if switching to Prem will negate the need to search out the ethanol-free stations (of which there is none in my area).
Thanks

Re: MPG Increase - Non-Ethanol Gas - What to Expect?
Here is MA all grades at all stations are E10 year round as far as I can tell. Might be a state regulation?

Re: MPG Increase - Non-Ethanol Gas - What to Expect?
Is there any reason to think that E10 occasionally isn't E10 ?
Any motivation to sell E15 as E10-?
Who actually does the mixing-
If it is done at the refinery-they won't cheap-no motivation,and someone would rat them out.
I'm just wondering why I read some many complaints-here and other places -about BIG drops-10%-in FE one they switch to E10
