I've heard that more and more places around the country, that REAL gasoline is getting rare, and I think you are being smart by asking...
Here's my thoughts. Use a good stabilizer..... I've heard that Briggs/Strattons is the best, but there are more and more of these products out there... so there maybe some better. Make sure that tank is full..... as ethanol will collect some moisture with an air space. With that, I'd go out and mount the beast and shake it side to side occassionally, to keep it from separating (ethanol does that), as when it does, that's when it gets ugly.
I have plenty of real gas in our area, so I really don't have to deal with that issue. I'm a very proud owner of my lil beauty..... with that in mind, I'd probably drain the tank myself. And no that isn't exactly convenient, but I don't want to deal with the liner coming out, and plugging the fuel pump and injectors. I realize that I may sound like an alarmist... but that's just where I'm coming from, dealing with 2 other X's in the past year with ethanol and storage...
