This is good information.A fuel filter has little bearing on the real problems with ethanol. When the ethanol/alcohol becomes saturated by the moisture in the environment it becomes heavier than the gasoline and falls to the bottom of the tank where the fuel pick up tube is located. This is known as Phase Separation. The moisture laden ethanol then becomes extremely corrosive causing rusting in a metal tank. Any engine that is subject to long periods of no use should absolutely avoid E-10 fuel if at all possible. Every small engine manufacturer makes this info readily available and recommends against the use of ethanol. Corn subsidies are a very powerful political force and the early primary states such as Iowa are major benefactors of these subsidies. Think about it this way. If E 10 fuel is OK for use in our motor vehicles then why is it that E 15 will void the warranties on any vehicles not specifically rated to use it? You are only talking a few more ounces of ethanol/alcohol in a gallon of gas so why should 10% be OK while 15% is not? The truth is that 10% generates a lot of votes and 15% will generate more.
I prefer my corn with butter on my dinner table or feeding the animals I eat but keep it out of my tank.
Here is my recommendation for keeping your ride during off-peak times of the year. (This goes for lawn mowers, etc. too) Here in the PNW, you never know when you'll get a nice day where you just want to ride.This is good information.
For those who cannot avoid booze-corrupted gasoline...what's the best plan? I thought about emptying the gas tank. Of course, condensation will hit it; but I'm wondering if leaving it open with some sort of breathable cover to keep out dust - like a plastic disc on spacers, leaving a gap at the fuel neck...if that would let it breathe enough to avoid inside condensation during winter weather temperature fluctuations.
Right NOW it's not a problem - I can get straight gas. But in the future...enquiring minds want to know.
If you go through a 5 gallon can of gas in your TW in a week then you don't need to do anything! The Seafoam won't hurt anything but it does not do all that much in fresh, Pure fuel that you are burning up pretty quick. The guys and gals that have to pay strict attention are those who live where their bikes are stored for months on end and usually in an unheated environment like a shed or garage. Much worse if all you can get is E-10 fuel because it will surely Phase Separate while in storage and I don't care what additive you put in it.I fill up the five gallon jug with ethanol free gas, regular. Mid grade and super are for high compression engines. I might start running mid grade when I get my 10.5:1 piston. Before I go fill it up I pour a couple glugs of Seafoam in the jug. I go through one a week, at least, so I don't worry about it. I can't afford to run that stuff in my POVs (car and truck).
