I try not to use E anything... Don't really like the bio-diesel thing either...  See what it has done to grain, fertilizer, farm land and farm equipment prices.... Wonder why horse feed is sky high..??

Think they tried using the higher Ethanol in the midwest testing school buses and turns out the stuff freezes.  They couldn't get them started in winter.

Don't have that option around here but would never use it anyway.

This ethanol issue just makes me angry...

I don't buy gasoline, I buy energy to run my vehicle.  Ethanol cheats me out of energy since I buy it by the gallon instead of BTU.

I own vehicles more than 20 years old.  Ethanol has already cost me $$ in fuel related problems.  (fuel pump, injectors, hoses, strainer, level sender, so far ..)

Gov't mandates in the marketplace are good for the few, bad for the many.

Examples... mandates shuttered the last US light bulb plant, increased electricity costs by subsidies for renewable energy, increased diesel costs by EPA rules, increased telephone service costs by paying for free obamaphones, plus more too many to list.

Retento ... You can't avoid E-10.  It is mandated in all gasoline.

If that's the case, there's alot of pumps in North Carolina that are not labeled...

 You can't avoid E-10.  It is mandated in all gasoline.

In upstate NY are many marine, snowmobile and RV dealers, that specialise in selling ethanol free gas. It is also 91 octane. You will find them in almost any tourist area.

Retento .. Maybe in your area E-10 is rare.  According to the state, 95% of NC stations sell E-10.  New labeling rule took effect only 6 months ago (June 1, 2012).  Previously, E-10 labeling was not required. 

The mandate is percentage based.  But, ethanol is cheaper to produce than 100% gasoline.  Just like watering drinks when the patron isn't looking... In this case, NC consumers were blinded by their legistlature. Previous sessions had allowed the labeling requirement to expire.

Two stores near me with gas without ethanol, one is 87 and the other is/was 93 octane.. Old country store a mile east of me HAD premium 93 gas with no "E-10" ... He's been unable to get that same fuel for about 2 months now, that's what we had been using in the Benz until he ran out, got the pump nozzles bagged. I guess that may be part of the slight drop in mileage now that we've been buying fuel all over, alot of 92 and 91 octane rather than the 93...

The other store is across the river from me carries 87 octane, I don't do business with them..... LOL!!

Don't see any Bio-diesel around here in my area, filled up in Asheville a while back with some B-20... Truck seemed to run OK.

North Carolina - NC     (House Bill 187 passed in 2011 now requires labeling but "not enforced".)

 How had is it to place a "STICKER" on a gas pump...?!!

Found this formula.  As you can tell by the price points it's dated, but just double the per gallon number to get close to current prices.

How much should you pay for E10 and E85?
If regular gas is $3.00/gallon you should pay
$2.90 / gallon for E10 (10% ethanol).
$2.13 / gallon for E85 (85% ethanol).
If regular gas is $2.00/gallon you should pay
$1.93 / gallon for E10 (10% ethanol).
$1.42 / gallon for E85 (85% ethanol).
Then you will be paying the same amount per mile driven.

The formula is this: For EX, where X is the percent ethanol

Ethanol price should = Gasoline price times (100 – X + X/1.52)/100

Notice that 100 – X is the percent of gas and X/1.52 is the percent of ethanol adjusted down by about 2/3 because it has less energy.
