re: Avgas 100ll vs. Truefuel

I have been using avgas on my 2 stroke motors for 20 years and have mentioned it several times on this forum plus a few others. Oddly no one has taken me seriously.

weedeater 20 years old and going strong.
Chain saw 18 years old and going strong.
blower 12 years old and going strong.

All Shindaiwa products

Ever change the fuel lines or primer bulbs with ethano?

Aviation fuel isn't exactly as available as E0, E10, or even pre-mixed stuff. I can buy a few gallons of Sunoco turbo blue easier than buy avgas where I am. I personally would not run any leaded fuel in my yard equipment. I've got a mid-90's Stihl 025 and an even older Craftman hedge trimmer and they both have run on E10 mixed fuel and still going strong. Proper seasonal maintenance matters more than anything else.

Ethanol won't damage fuel lines and carburetor parts in equipment made in the last 15 years or so, just like automobiles they've been using fuel system parts that do not degrade simply because of ethanol. What does damage fuel lines still is age and exposure to sunlight, I just replaced the primer bulb on a Shindaiwa T242 that a yard guy keeps on his trailer. Guy uses E0 and good 2-stroke mix and the bulb still split in the middle, hardened with exposure. Fuel lines were still good because the are mostly shielded by the plastic housing around the air filter and carb.
