i was thinking about this. if you mix one gal. at a time the differance is only around $.20. that's not much. if ya can't spring for the extra you should probably be working more OT and spend less time fishing. however. the small engines are already working very hot. if you use the high octane wouldn't that put more wear and tear on the parts? just a question. i really don't know. i'm not smart enough to figure this stuff out!
