Does E10 offer better detonation properties? You bump your timing and have more performance and better MPG. Does E10 offer any water absorbing properties to remove any water in your tank and keep it free of moisture? Does E10 offer any octane advantage or is that reduced or off-set by the gas distiller mixing crappier gas to make your 93 octane? Does E10 burn slightly cooler helping to keep exhaust temps down? I don't know these answers so I thought I would ask. It's like for every 10 gallons of gas you put in your car 1 of those gallons was moonshine What's wrong with that? |
I'm not going to pretend that I'm an expert on ethanol, but here's some stuff I found mixed with a good dose of stuff I think I know from reading other stuff over the last few years.
The first four are from the Wikipedia article on ethanol. The rest are the things I think I know.
1. Ethanol contains approx. 34% less energy per unit volume than gasoline, and therefore in theory, burning pure ethanol in a vehicle will result in a 34% reduction in miles per US gallon , given the same fuel economy, compared to burning pure gasoline.
2. Since ethanol has a higher octane rating, the engine can be made more efficient by raising its compression ratio.
3. Based on EPA tests for all 2006 E85 models, the average fuel economy for E85 vehicles resulted 25.56% lower than unleaded gasoline.
4. The total amount of energy input into the process compared to the energy released by burning the resulting ethanol fuel is known as the
energy balance (or "
Net energy gain"). Figures compiled in 2007 by
National Geographic Magazine[49] point to modest results for corn ethanol produced in the US: one unit of fossil-fuel energy is required to create 1.3 energy units from the resulting ethanol. My note - which is then between 25% and 30% less fuel efficient and makes it close to one to one which means it's a waste of time, money, and energy.
5. Ethanol is corrosive to rubber and plastic that are not designed for ethanol use.
6. Ethanol is added to gas at the shipping terminals immediately before the gas is sent to the stations because of both the corrosive nature of the ethanol and the fact that it does absorb a fair amount of water from the atmosphere.
7. In this country the vast majority of ethanol is made from corn. That's food and it's just a bad idea to use that as a source.
8. It's bad for our checkbooks. We pay subsidies to corn farmers to grow the corn, and then we subsidize the ethanol production in the form of tax breaks for the ethanol producers. After all that, we're taxed by the feds and our local governments on whatever comes out of the pump.
I think that's about it. I'll put the soapbox back in storage for now
