I will not say a lot about this subject except I agree with Denny and Harold on this. I have ran E-10 for many years thru farm tractors, cars, new and classic pick up trucks, lawn mowers , 2 cycle chain saws and weed whips ETC with out issues. IF and that little word is HUGE, You start out with old dirty fuel storage tanks and dirty gas cans, gas tanks on the vehicles, YOU ARE GUARANTEED to have problems as Ethanol will remove old varnish, crud, ect and release it to foul up your fuel filters, and carburetors. Also, Keep fuel containers tightly closed as Ethanol will absorb moisture from the outside air and that is the cloudiness you see in the fuel filter picture posted earlier in this discussion. Try this as an experiment. Take 2 baby food jars and fill both with E-10 or even higher E content. Close one tightly with its cover. Leave the second jar's lid off, exposed to the atmosphere. Report back what you see in a few days depending on the relative humidity . Once you have a fuel storage system and storage tanks cleaned you WILL NOT have any further problems with Ethanol.Other than a small decrease in fuel mileage, ethanol is good for this country's economy. It puts Americans to work rather than foreigners. It keeps more family farmers in business who purchase YOUR PRODUCTS. I am now getting into touche territory so end of my rant. Jerry
