Because it has Ethanol in it. The Ethanol increases the octane and lowers the price.AnswerBecause it has ethanol in it. Ethanol actually decreases the power of gasoline, and subsequently decreases mileage as well. Interestingly, it also makes gasoline more expensive- BUT - this is Iowa, and the government is subsidizing the addition of ethanol to gasoline. In Missouri, where the government does not subsidize, gasoline with ethanol is MORE expensive than its Iowa Counterpart. Long story short, its cheaper because of government subsidies.
No, its bad for your engine Sure you can mix them as long as your vehicle has a flex fuel engine. You can also mix then in a non flex fuel engine as long as you do not mix more than 10% ethanol with plain gasoline.
Honda does not recommend anything more than 10% ethanol blend. All gasoline now is E10, and Honda says E10 is fine as long as it is the same or higher octane as 100% gasoline. I use E10 in my 1991 Accord with zero problems.
Expect around a 15% decline in fuel mileage over conventional gasoline. Ok, so if I'm paying $4.00 / gallon for 10 % ethanol gas and loosing 15 % mileage that means if I can find 100 % gasoline with no ethanol at $4.60 / gallon I'm getting basically the same thing. So if I pay $4.10 / gallon for real gas without ethanol, I just saved $.50 / gallon over the ethanol low output gas. This should make shopping allot easier, as long as the stations are required to post how much ethanol they are selling versus real gas.
that could be a pretty long list. I will cover the big ones. There is approximately 20% less energy in ethanol than there is in gasoline. It is possible that the computer module notices the difference and cannot compensate in the air fuel mix adequately to get a clean, efficient burn. Ethanol is a corrosive, or at least much more corrosive than gasoline or blended gasoline. Over time, ethanol will eat through rubber based gaskets, seals and hoses. That will cause all kinds of problems for your car from the fuel pump, right down to the injectors.
While not as a chart, this is an idea about combustion energy values: Ethanol 77,000 Btu per gallon, Gasoline 125,000 Btu per gallon, Diesel 135,000 Btu per gallon and Biodiesel 130,000 Btu per gallon. Grades of fuel imply differences in composition and thus differences in combustion Btu values. Combustion values for ethanol will not depend on source of ethanol as long as ethanol content/composition is the same. Ali Hamza A_Hamza@yahoo.com
Ethanol stays as long as you want it to ;)
I have been running my car on E10 for as long as it has been available without any bad effect. The rumour that ethanol was bad for your engine was started by the fuel companies because they lose money when you are not pumping CO2 and CO3 into the atmosphere. In Australia they even managed to have a maximum mix put in place, 10%. In some of the older cars ethanol did have an effect on some of the fittings in the fuel system but that problem has been overcome now.
If we're talking about gasoline/petrol, then yes as long as it meets the minimum octane required for your car. If you consider "boat fuel" as ethanol free fuel then yes absolutely you can. Using fuel containing ethanol in boats however creates problems.
Ethanol, long an additive to gasoline, is by itself an alternate car fuel which burns more cleanly than fossil fuels. Most internal combustion engines, however, cannot burn pure ethanol so it is used as an additive. Biodiesel is similar, made from oils of plants such as soybeans or animal fats, then added to traditional diesel fuel. Hydrogen cells and electric batteries are other sources of alternative car fuels.
pluses: ethanol is an altenitive energy. this means that if we use ethanol we become less dependant on petrolum. minuses: if more and more people become dependant on ethanol we, the US, will have to grow more corn to satisfy that demand.
