To end the confusion of what I meant, the opinion of one person versus the reality of a mass of millions of unsaid experiences is a pretty patch of thin ice to put all one's weight on.
I have had "gumming issues" with alcohol laced gasoline, even when using a Racor N-series element in a fuel water separator filter in gasoline service. I will kiss someone's moonie if they can find a filter that has a finer filtration than 1 micron, and is made for automotive use.
None of the "Top Tier" gasoline sources of sale are to be found in Central Texas or East Jesus, without alcohol? Chevron or Shell or Union only with alcohol added?
The ONLY reason alcohol is used as an additive is that it apparently combusts, has no hydrocarbon emissions issues, and has bought and paid for just about everyone in government regulatory positions. Doubt it? Look at corn futures versus the timing of introduction of booze into gasoline. Go to foggy bottom or your state capitol. Peruse the strategic location of the corn/alcohol industry's office to your legislature.

Then attend a midget sprint car race or the Indy 500. Your tears of joy cannot possibly be related to exhaust emissions of alcohol fueled race cars. The emissions the cars spew are NOT ANALYZED, or categorized in government emission categories.
Ethyl Corporation wanted to introduce HI-TECH 2000 Manganese component additive for fuel but no studies were ever conducted by the government. Why? The bulging pockets of legislators "lubricated" by Archer Daniels Midland and the corn lobby were so huge it did not allow Ethyl Corporation to get within earshot.
