Thanks I will look into that I don't want to be taking apart and cleaning my carb regularly.
You're welcome, anytime.
Even if you know how to service carbs (many don't, today), there are other things most of us would rather do !
Growing up in the North, I was taught to park with a full gas tank. The condensation issue seems intuitive if you have to deal with Winter, but the reality is that unless you live in the middle of the Mohave, you probably have to worry about condensation in fuel tanks. This issue mattered even with olde school gas, but it became ultra critical once the ethanol dilution game came along.
Another thing to consider is that as the % ethanol climbs, the lubricating properties of the "gas" declines. To combat that issue, I run Lucas Upper Cylinder lubricant in the road vehicles that I run E10 in.
These new fuels definitely remind me of the "Ounce of Prevention....." saying.
If you really want to scare yourself, read through this material about the impact of E15 - one of the links on that page takes you to a very detailed test of fuel pumps (2001 and newer). Not pretty.
Tests show E15 use may harm fuel systems in millions of vehicles
