I have been going through the chemistry of this list though,l and the one striking feature is that so many of the chemicals listed are teh same thing with different names.  I'm betting a can of xylol from home depot is much cheaper than buying a case of  FI cleaner, and that adding a few available chemicals to an oil base (marvell, lucas or bllendzall) might result in a really good mixture for the chemically inclined.

I could not find a complete list, but here are common additives by class.  To check a particular product, google it with "msds" after the name and you will get quite a bit of information, though companies are allowed to list ingredients as "proprietary.


    Oxygenates
        Alcohols:
            Methanol (MeOH)
            Ethanol (EtOH)
            Isopropyl alcohol (IPA)
            n-butanol (BuOH)
            Gasoline grade t-butanol (GTBA)
        Ethers:
            Methyl tert-butyl ether (MTBE), now outlawed in many states of the U.S. for road use, mostly because of water contamination.
            Tertiary amyl methyl ether (TAME)
            Tertiary hexyl methyl ether (THEME)
            Ethyl tertiary butyl ether (ETBE)
            Tertiary amyl ethyl ether (TAEE)
            Diisopropyl ether (DIPE)

    Antioxidants, stabilizers
        Butylated hydroxytoluene (BHT)
        2,4-Dimethyl-6-tert-butylphenol
        2,6-Di-tert-butylphenol (2,6-DTBP)
        p-Phenylenediamine
        Ethylene diamine

    Antiknock agents
        Tetraethyllead, now banned almost everywhere for causing brain damage and violent crime.
        Methylcyclopentadienyl manganese tricarbonyl (MMT)
        Ferrocene
        Iron pentacarbonyl
        Toluene
        Isooctane
        Triptane

    Lead scavengers (for leaded gasoline)
        Tricresyl phosphate (TCP) (also an AW additive and EP additive)
        1,2-Dibromoethane
        1,2-Dichloroethane

    Fuel dyes, most common:
        Solvent Red 24
        Solvent Red 26
        Solvent Yellow 124
        Solvent Blue 35

    Fuel additives in general
        Ether and other flammable hydrocarbons have been used extensively as starting fluid for many difficult-to-start engines, especially diesel engines
        Nitrous oxide, or simply nitrous, is an oxidizer used in auto racing
        Nitromethane, or "nitro," is a high-performance racing fuel
        Acetone is a vaporization additive, mainly used with methanol racing fuel to improve vaporisation at start up
        Butyl rubber (as polyisobutylene succinimide, detergent to prevent fouling of diesel fuel injectors)
        Picrate improves combustion, increases fuel mileage
        Silicone is an anti-foaming agent for diesel fuel, but may damage oxygen sensors in gasoline engines
        Tetranitromethane can increase the cetane number of diesel fuel, improving its combustion properties

A riding buddy of mine is a big enthusiast of Seafoam.  I've never used any additive, though--never had a problem for which that seemed a solution.  Just lucky, I guess.  Or maybe my carburetor (singular) and old-fashioned type of engine are more forgiving than higher-tech, more modern equipment?
 
Barry, why do you add Seafoam for the first 300 miles of a long trip?

Since the main purpose of the stuff is injector cleaning (jet cleaning of you have a carb), 5 or 6 hours straight of high flowrate satisfies my engineer's desire for a "blowdown".  Ironically, with a carburetor you have the opposite concern, the place you are apt to get the most fouling is in the low speed or idle jets.  My last bike was carburated, and needed either to be ridden constantly, or have additives.

 Did you run ethanol based fuel!? If so that is the problem. I'd trust 3 month old NON ethanol fuel in a carbed bike then 3 week old ethanol WITH cleaning additives! Ethanol is crap no matter what garbage the EPA saids! I remember running it by accident in my FI bike when we were up in Vermont both me and my buddy thought our fuel gauges broke while also noticing our bikes ran like TOPS! Then we eventually figured out we must have gotten Ethanol free gas!

I get much better mileage when using the ethanol free, but hard to come by in CT.

Barry,

I didn't think ethanol free gas was availabe in CT?

It is not, I have gotten it in other states.  I can tell because my gas mileage goes above 70 mpg.

To clarify, not available at the pump, but there are places you can buy it in a very expensive can.

from MCN:
I have a 2008 Yamaha Majesty, and I was told to add a product called Marvel
Mystery Oil to my gas tank—1.5 oz. for 3 gal. of fuel. I get decent gas mileage, and
I did have a problem with the scooter, but it is being fixed now. Marvel Mystery Oil
will supposedly help the injectors and the many parts of the fuel system. I read one
guy has used it since he’s owned his 2007 Majesty, and he just got done riding from
Connecticut to California and back. He also stated that he has 60,000+ miles on
the scoot, my question is, are there any opinions or information out there that
oppose this practice? I don’t want to screw something up by doing this.
Bob from Michigan No worries here, Bob. This is an age-old practice with an old-school product.
Marvel Mystery Oil will not harm anything—it may not help, but it won’t hurt.
Adding Marvel Oil to the gas has been a practice since forever. The ideas behind it
are to limit rust in the fuel tank, provide some carburetor lubrication, top-end
engine lubrication and possibly increase fuel longevity by helping to keep the gas
from going stale. You are fine with this practice.
On a similar note, some other folks I know and I will often run a high-quality
two-stroke oil at 100:1 or 200:1, for the same purpose in our four-stroke
motorcycles. My personal favorite is the old-school Blendzall #485 “Gold
Label” Racing Castor/Power Booster (www.blendzall.com), as it boosts octane,
provides top-end lubrication and smells really good coming out the exhaust. I get
comments on this from time to time: “What are you running in that bike? It
smells like an XR750 dirt track racer!” Fun stuff! It is, of course, much more
expensive than Marvel Mystery Oil, but it does more. The Blendzall would not
be worth the expense for your Majesty scooter unless you are having detona-
tion/engine knocking under load from poor-quality gasoline.
