Since the days of unleaded becoming the standard, I have read accounts of people trialing various additives to help preserve engine components. Most of these are designed for larger engines such as cars, but some report successful results in smaller 4 stroke engines as well. Others say to add a drop or two of 2-stroke oil to their fuel can each fill up.
I have personally noticed that plugs and valves get blackened in no time with unleaded fuel and I am forever cleaning plugs.
But what are we all going to do when they introduce Ethanol blended fuel as the standard? We can expect new additives will instantly appear on store shelves, but whether any of these products live up to our expectations is the question. I wonder if there is anything the every day mower enthusiast can do to ward off the bad effects of ethanol fuel? Would adding some more 2-stroke oil to the fuel help to reduce the negative effects by providing more lubrication and maybe cooling things down a fraction (in theory)?
