Time for gasolin summer mix yet?

Page 1 of 4  
Anybody knows when the US refineries are supposed to switch to summer mix? Getting tired of ethanol.

On this side of the pond we only get one standard of fuel year round. However, we have our priorities right, most decent breweries do summer and winter ales. Down at the pub a pint goes down very nicely.

Gonna be kind of stuck with it. The Feds want it in the tank. So it's in the tank. Just be glad the corn farmers don't get their way and go to 20%.

I live in California and the other incentive, for the state, to want more ethanol, is that we pay taxes on the gallon, and ethanol reduces gas mileage, so one has to buy more gas, for the reduced mileage and pay more taxes on "watered-down" fuel. The more ethanol they can get into the fuel means more tax dollars to them.

with ethanol, fuel gets watered down for real too - ethanol allows real water absorption. it's not a lot per gallon, but you multiply the volume by the number of gallons of fuel used per day/month/year across the state and you're talking significant dough. enough to pay a few political contributions and some bonuses.

On the plus side ethanol in the fuel stops condensed water collecting in the fuel tank.
Yes ethanol mixed in the fuel will reduce the mileage some, but the effect is not that big. About 2% http://en.wikipedia.org/wiki/Gasoline_gallon_equivalent
Since something needs to be added as an octane enhancer, the other common alternative is MTBE, which has about the same effect on mileage as ethanol, and MTBE has worse environmental problems than MTBE.
The effect of ethanol in the gas mix, is far less than environmental factors temperature, rain or snow on the road, and is far less than the effect of driving style.

so i'm enjoying a 2% price reduction for my gasoline, right? oh, wait, through my elected "representatives", i'm giving tax subsidy to farmers, i'm giving tax subsidy to ethanol producers, giving tax write-offs the oil companies, and through my reduced mpg's, /increasing/ my state gasoline tax revenue.
and 2% is "not that big"? we consume >175 billion of gallons of gasoline a year. 2% of that at $3.80 a gallon is $13 billion a year, excluding all the tax bullshit. to put that in perspective, nasa gets $9 billion a year and the national science foundation gets under $7 billion. a spectacular misallocation of funds with spectacular long term negative impact.

I think that 20% would be more accurate in real life situations. That "2%" is a figure having about the same accuracy as the old EPA mileage estimates...

"2%" is the rough [rounded down] difference based on calorie content for traditional gasoline and that same gasoline with pure ethanol in it.
but that presumption is huge. in reality, there is water content, because ethanol allows miscibility, and ethanol also allows lower grade hydrocarbon fractions to be used because of ethanol's knock suppression. so, while i doubt it's 20%, it does indeed seem to be somewhat more than 2%.

I think another factor is brand of gasoline. The discount brands are definitely noticable with regard to lowered mileage. OTOH, I've been using Shell mostly and there's not a huge difference.
But I sure heard a lot of howling from my "el cheapo" friends that buy only discount gas...

so, the $3.89/gallon gas is really $3.97/gallon equivalent when you end up doing the math.
"not that big", eh?

No not big. Weather effects run much larger (25%). It is commonly reported that driving habits are big, and many people (not all) could get 10-30% improvement with a combination of proper maintenance and change of driving habits.
Also you miss the point, something is needed to give the octane rating need by car engines. Traditionally lead was used, but that had serious drawbacks and was withdrawn for good reason.
The alternatives seem to be: MTBE or ethanol, both of which will cost cost 2% or so in mileage. MMT which may or may not have environmental/health problems, but does gum up catalytic converters, and engine control systems (eventually resulting in worse mileage).

MTBE in our winter fuel here in Alaska. It didn't even last the first winter. They were told by our Governor at the time, after about two or three months, that MTBE was a health hazard and increased fuel consumption by such a degree that any emission reductions were lost, in fact reversed and it would NOT be used any longer. The fuel vendors were directed to cease putting it in the fuel immediately, which they did....

And the more grain is used for ethanol production the less is available for food, driving up food prices. Let's say thanks for that to our well-meaning politicians.

I read in the paper that some 40% of corn production is being diverted for use as fuel. Absolutely insane.
