Gasoline VS Ethanol -Plus Shop Tour & Small Engine Winterization and Care

What happens here

Begin by understanding the primary issue: modern gasoline, especially ethanol-blended fuels, has a significantly shorter shelf life, typically staying fresh for only 30 to 45 days in a can. After this period, the fuel loses its combustibility, leading to starting problems in small engines. More critically, ethanol actively degrades rubber and plastic components such as seals, gaskets, needles, seats, and diaphragms within the carburetor and fuel lines, turning them into a 'mushy' substance. This breakdown causes fuel system blockages and eventually engine failure.

Goal: Recognize how modern gasoline and ethanol impact small engine performance and lifespan.

oxygenated gas crit correct non oxygenated no ethanol fuel okay and so what do you run in your equipment we run non oxygenated 92 octane um regular unleaded gasoline Okay so tell me about how the fuels have changed and what it's doing to small equipment today with the small equipment with the ethanol Blended fuel the the gasoline only lasts about 30 to 45 days in a can before it loses its freshness okay so what happens when it loses freshness what does that mean it doesn't it doesn't combust as well in a cylinder okay so if someone has a can that they've left over the winter and they dump it into their trimmer or their chainsaw and it doesn't start right away it doesn't have that com Buble cuz the ethanol is breaking down okay so so but more important than that isn't the ethanol in there destroying the seals yes it's it it breaks the rubber down and the rubber on the little needles and seats inside of and the diaphragms inside of the carburetor and makes them almost like mush same thing with the fuel lines um if you see something that sits for a couple years you can grab the fuel line and it's just much so that's like if you store your equipment if you're going into the fall and you're putting it away for the season yes and you have just standard gasoline in your equipment don't be surprised if it's not going to run right in the spring exactly yes cuz it it gums up it gets almost gooey inside of the carburetor okay so again I've seen that I've seen hoses where it's just like why do this hose like feel like it's just yeah yeah like it's broken down okay yeah it's mush and what it does is it plugs all the little Port holes and all the little um I'm trying to think out lost for words now plugs all the little passageways in the carburetor so that the fuel can't get okay let's walk over and look at
