There is no difference in additives between the different octanes. Take a look at your local gas stations and see how many tanks they have to store fuel. I'll bet you find more than one that have only 2 tanks, one for regular(87) and one for super(93). They use a blend valve to get mid grade(89). So are they combining crappy 87 with great 93 to make ok 89? No. With your experiment if you see any dirt or debris or impurities then I suggest switching brands or stations, cause that should not happen. Any fuel left over time is gonna break down especially race gas!! The only things that make fuel break down is light, air, moisture, contaminents and time. The best octane to run is the lowest that your motor will allow. By that I mean smooth power, no detonating or pre ignition. Manufacturers recommend running Super for one reason, all motors can run it with no issues. They just CYA with that statement....
And as far as impurities goes, you can't see them with your eyes, really, but they are there and they are too big by comparison. They leave combustion residue that super does not.

SS97 good stuff you know your stuff "in chemical words" i do agreee with you because with expirence of me going from regular to super that super is better.But quick question you know those lil packets you put into the gas that boost up the octane can i use that is it a waste just curious?

You guys must have some really suped up 400s[img]i/expressions/face-icon-small-smile.gif[/img] the manual that came with the bike says to run 87 octane. From my real world experience, if you start getting the "diesel" effect, then, jump to the next octane level. Now, if you've done some decent mods to it, you might need to jump up your octane. Outside of those scenerios, your just pouring money down the tail pipe[img]i/expressions/face-icon-small-sad.gif[/img]
As far as the 400ex, IIRC, Honda recommends a high octane to be burned in it.

Not totally true. As you said the super and the regular are in different tanks, so there you have it. The plus will then still have the addatives that the super contains right? And no Super DOES NOT break down like regular. You are obviously not speaking from experience. Regular will form a ring of water at the top in almost no time at all.
And as far as impurities goes, you can't see them with your eyes, really, but they are there and they are too big by comparison. They leave combustion residue that super does not.
