To this question, http://www.fuelsystemguide.com/what-is- ... treatment/ has a claim. I have been using the mentioned magical Lucas Oil Ethanol Fuel Treatment for a few years with nothing to complain about - it starts and runs as it should with no performance degradation that some have noticed after prolonged 10% ethanol fuel usage. Perhaps it successfully counters the negative effects of ethanol, or perhaps it vaporizes immediately after you pour it in, I can't really say. The claim in this article for the Lucas treatment is:Post by colin7673 » Thu Nov 09, 2017 1:31 pm

Is there a additive that can be added while filling up.. and which is best to use..
"Lucas Ethanol Fuel Conditioner is one of the “fan favorites” for ethanol fuel treatments. It was designed specifically to treat ethanol fuels. It is an extremely potent blend, so make sure you do the math before you use it: one ounce treats five gallons of fuel, so one bottle will treat up to 25 gallons. The conditioner works to prevent rust, stop separation, and inhibit corrosion that ethanol fuels so often cause. But unlike some of the other brands, it doesn’t stop there, it also cleans injectors, valve seats, and combustion chambers. This particular Lucas safeguard ethanol fuel conditioner is also recommended by the marine industry, as it works well with boats. If you want a fuel stabilizer for storing your fuel then you might be better using Star Tron Enzyme Fuel treatment instead, as this is specifically formulated for storage. However if you run your engine regularly and fill up your gas tank more often then we highly recommend this product."
As most things in print are assuredly true, I assume this must be, too. All I can say is that after several years of using it, I have noticed no negative changes. Can't say the same for the anti-aging vitamins.
