Not tried 360, but a friend turned me on to using the stabil marine which supposed deals better with ethanol problems. No issues since I started using it years ago. Both my challenger and my GSXR have sat for months on end with no noticeable ill effects. Just recently rebuild the holley on the challenger and there was zero crud.

I will back up and say I had an issue with the motorcycle from dumping a bottle of seafoam or something in the tank after storage. Barely ran to the point of not being safe to drive (stalling, no power) pulled the plugs and they were fouled some weird red color. Changed plugs and it ran like a champ again. Note to self - don't mix and match fuel additives in the same tankful.
