Congress ends corn ethanol subsidy

Ahh, I don't think so. We've had 10% ethanol in CT & NE for over 12 years. Not one single problem with any car, heads, carb, fuel lines, etc. Every one in perfect shade, including '40 Chev, 62' Vette with modified engine, '68 Impala wagon, and a few others I've sold. Just because a subsidy ended doesn't mean ethanol is going away. In fact, it will be mandatory in all states. With subsidy ended, price of gas should go down now.
We've had it in Wa. State for 30+ years. No problem here either.

The discussion was to use more corn and subsidize more to create more ethanol. A blend of 15% is considered by most to be destructive to older engines. That's where all this started. So the fact they are suspending subsidies will likely cause the same fuel to rise in price if the mandate remains to keep at least 10% Ethanol.
All I know for sure is what 3 engine builders have told me, and they are seeing significant cracking in the valve seats if higher concentrations of Ethanol is used. I am no chemist, all I am doing is repeating what these guys have said. At the same time they report gasket breakdown and gas lines off gasing.

Is sugar ethanol superior? I think Brazil has switched over to 100 percent sugar derived ethanol for vehicle fuel.
They have wanted to export to the USA, but the corn lobby has blocked that. Maybe we'll have a choice now?

You've yet to state who 'they' is other than mentioning an anonymous bunch of engine builders. Since E15 does not yet exist in a commercial sense, how have these three builders amassed sufficient experience to conclude that it does harm to older Corvette engines?
Many of us here have decades of experience using E10 in our older Corvette engines and have seen no such deterioration.
Did 'they' also recommend installing hardened valve seats when leaded fuels were discontinued?

I say eat the corn and drill for oil. Our food would cost less, we wouldn't need mid east oil and there would be thousands of jobs. Of course we would ruin the earth and all die in a blaze of global warming according to the EXPERTS.

Modern engines all use hardened valve seats because the cylinder heads are aluminum, not because of any concerns about ethanol; hardened seats aren't required with iron heads.

I thought hardened valve seats came into the picture when lead was being removed from our fuel? Talk of sunken valves etc...
