How badly do you suppose ethanol would gum up this old engine?

It’s pretty well established that motorcycle engines and ethanol do not play nicely together, particularly when the proportion of ethanol in the gas get beyond a certain point. And using high-ethanol gas can reputedly even invalidate your warranty on the bike.

So it should not be a surprise that ABATE of Colorado opposes E-15, which is a newer ethanol fuel that has 15 percent ethanol, vs. the 10 percent we have had for many years. E-15 crosses the line.

I got the following alert from Stump, who keeps track of legislation for ABATE and does what he can to promote or oppose bills. That is to say, he’s a lobbyist, our lobbyist.

On Monday, 3/28, SB16-175 (E-15 Gasoline Income Tax Credit For Retail Dealers) was introduced in the Senate and assigned to the Senate Finance Committee. The Senate Finance Committee Members are: Sen. Neville (chair); Sen. Hill; Sen. Holbert; Sen. Johnston; and Sen. Kerr. I requested a meeting with the sponsor of the bill. I also plan to get a letter out to the Senate Finance Committee members and possibly meet with a couple of them before the committee meets on this bill which is scheduled for Thursday, 4/14. Now would be a good time to write / e-mail the Senate Finance Committee Members and urge them to oppose SB16-175. I’ve attached some talking point about E-15 Fuel to use in your letters. Please forward this to your district members ASAP and encourage them to e-mail the Senate Finance Committee Members.

Thanks,

Stump

You can read that letter with talking points that he mentioned here.

There are two issues as far as I see it. First there are the detrimental effects, of which Stump lists four:

PROBLEM 1: DEBRIS IN FUEL
Gums rapidly form in the fuel tank and fuel delivery systems as ethanol fuels age. However, ethanol is also a powerful solvent that will strip away and disperse this build up back into the fuel as large, performance-robbing particles. This leads to clogged filters, injectors and carburetors.

PROBLEM 2: EXCESSIVE WATER IN THE FUEL AND PHASE SEPARATION
Ethanol attracts moisture from the atmosphere, forming an ethanol/water solution mixed in the gasoline. Ethanol-blended fuel will naturally hold .5% water in suspension, but when water levels exceed this threshold, or when the fuel cools significantly, the water/ethanol mix drops out of suspension. This is phase separation. Excessive water in the fuel tank causes engines to run rough, stall, and can lead to internal damage to engine components. Ethanol provides a significant amount of the fuel’s octane, so when the ethanol/water solution separates and drops to the bottom of the tank, the remaining fuel is left without enough octane to properly operate the engine. Additionally, the ethanol/water solution can become partially combustible, which can lead to engine damage.

PROBLEM 3: ETHANOL FUELS BREAK DOWN QUICKLY
Over a short period of time ethanol fuel begins to break down. As ethanol and other components evaporate, the fuel loses octane and becomes “stale.” This causes hard starts, pinging and engine knock, which robs your engine of power and can cause damage.

PROBLEM 4: ETHANOL CAUSES LOST POWER, PERFORMANCE AND DECREASED FUEL ECONOMY
Ethanol fuel does not produce as much energy as traditional fuel. This results in inefficient combustion, decreased performance, reduced throttle response and poor fuel economy.

The other is that the only reason this whole ethanol thing has not died is because of the political pull of the corn farmers. Like so many other people I supported the idea of adding ethanol to gas originally, but like so many others I have now come to see that the whole things is a waste. It takes nearly as much energy to produce the stuff as you get from burning it and it’s not good for your motor. We tried it. It failed. Let’s kill the program and move forward. Oh, no–now we have vested interests.

At least if we could get SB 16-175 killed we wouldn’t be giving a tax credit to the stations that sell the stuff.
