And by diluting gas with it; the supply can be larger due to the blend; meaning less gas per gallon, which in turn burns less, meaning we (the driver) pay more, quid pro quo; more money to be made

The biodiesel practically not only saves money, but pays since some will pay to remove the grease and ---- (and you can undercut larger trucking prices; both sides win)

Yeah, the only problem with biodiesel is its gel point, and biodiesel is hydrophilic. At around 18ºF weather it needs to be blended with kerosene. And fuel lines and tanks have the possibility of rusting because of the small amount of water in the biodiesel. Also the water in the biodiesel cools combustion. But the water situation can be avoided. The problem with diesels is the strict particulate material laws were put on by the EPA as a means to curb diesel cars being more popular in the united states.

got gas today and the pump said "no ethanol" so I guess its better

Isn't pre-ignition (i.e. detonation) what kills a lot of engines? Even if you have to run more fuel through the engine, wouldn't you theoretically be able to run with more timing than you would a lower octane fuel?

Re: Ethanol in gasoline...how does it affect?
 

yeah you make less power with more ethanol, you need a richer mixture with more ethanol and it does kill your milage. The thing i dont like about ethanol is that is corrosive as hell... like E85 bleck

That's what I was referring to.

Re: Ethanol in gasoline...how does it affect?
 

I had to do alot of research for a FSAE team I was on (we were running E85, and we had to run a 19mm restrictor vs the 20mm for gas).

E85 IS corrosive to aluminum, but it's not that big of deal. Many people run it on stock fuel systems. It is recomended to only use it w/ hard anodized aluminum or stainless steel though. It contains less energy than gasoline, but it is an oxygenating fuel. So you can make more power with the same amount of air as a system running gasoline, though you need more fuel so the MPG drops. It burns cooler than gasoline, so you won't need as big of a radiator on a system that only runs E85. It also is cleaner than gasoline, so fuel system problems are less likely on systems that have always run gas, though if you are switching from gas you may have problems because it will break down deposits left by gas in the tank, lines (and anywhere else) and they will probably get deposited in the injectors or filter.

Re: Ethanol in gasoline...how does it affect?
 

Having to run 10% ethanol is actually increasing gas prices. As we all know, ethanol production is limited. The fact that we need to use 10% of it in every gallon means we need to produce a lot of it. Guess what, not enough resources! So now we have a bunch of Americans at $12.00 an hour working over time which ends up increasing our gas prices any more. Nevermind that the price of oil is increasing as well. So basically we are fucked. If you are going to make me use ethanol atleast give me that E85 ---- so I can run gobs of boost on a high compression engine. This 10% ---- is worthless. I suggest people who are tuning now, run even leaner in part throttle. You should be able to run leaner AFRs more easily with ethanol.

if it eats away at steel and alum what the hell they gonna make the motor out of straw and mud :8
