ethenol, cornjuice, crapgas whatever you call it, it's all CRAPOLA!
I hate running it but it's just so hard and expensive to find real gas anymore, I gave up lookin for the real stuff and run ethenol in everything. My wife and I have 3 autos we drive constantly so the fuel in them gets burned out so I don't put stabilizer in it every tank. My oldest son and my daughter are teen aged drivers as well so their autos likewise don't sit. I just run a bottle of B12Chemtool in each a couple times a year. (which is mainly acetone and MEK so it's STOUT stuff, but you don't want it sittin in the tank or fuel system. I put it in my stuff only when it's going to all be burned out in a day or two)
I do however have some toys and equip that DO sit between uses so I do keep the fuel in them treated. On my farm I have my Lowe 160, a 1980 K10 pickup and my 70hp 4x4 Kubota (turbo diesel) so I keep Stabil Marine in the Lowe and pickup (1oz per 5gals). In the Kubota I keep Stabil's diesel treatment in it and likewise run a bottle or two of Diesel Kleen in it a couple times a year. At home in the garage I have my Allison and next to it sits my 1972 SS454 Chevelle (yes, real W-code 454 car). I keep the Allison tank treated with Stabil Marine and then use the B12 a couple of times a year. In the Chevelle I don't run it enough to trust using the gas in it most of the time. (It was my dads, I bought it from him in 2008 and I guess I'll keep it forever just because it was his. Despite a few close calls, he's still around luckily!) Most of the time when I run the Chevelle I drain the entire tank (which I keep treated with Stabil Marine as well) and end up dumping that fuel in one of our daily drivers. I see Stabil has a new "360 whatever" stabilizer that coats the entire tank, I might get a bottle of that for the Chevelle starting this spring.
My bro Todd Bucknell of Hydromotive Props is a distributor for ACES additives and they've had AMAZING results in their 2.5 and Drag motors so I might hafta start using some of that ACES in some of my toys!
