I'm not telling you to throw your fuel away--that is the last thing I'm telling you to do. HOwever, all I'm saying is that if you truely aren't going to be flying for SIX months, then don't expect a previously open container of fuel to satisfy that saito. I've had fuel go bad that sat for only a couple of months. And, it really didn't "sit," but rather it just took me that long to use it--flying was slow for a period. Sure, the OS 40 LA's would run it fine--but they'd run on FAI fuel just fine. However, the saito wouldn't even start on it. Just my .02!
