All info here is from the package.
Fuel is made from many components, in the combustion process the lighter components, which burn to fast at the beginning of the combustion process causes preignition and the heavier ones, which burn to slowly causing both smoke and carbon buildup. Getting a more complete burn of the fuel resulting in cleaner,better running engine that will start easier, and burn less fuel with increased power and performance.
Claims also that no need to put stabilizer in for winter storage. Only looke like 4 lead discs in a plastic sleeve.
I have no connection to the product or endorse it. Only looking for others thoughts or anybody using it.

Another snake oil... no interest!

 

Call it snake oil if you want but a buddy of mine sells these and I put it in my tank. I am particularly grateful OP posted this as I have a 7 gallon tank going on my bike and need to remember to get it out and put in in the new tank.

 

OK, Snake Oil.
WTF, if there is/was some glorious magic fix to all fuels,, why on earth isn't it added to all fuels?
Mandated by the Government to protect all of us un-knowing consumers from the foul fuels we're given at every pump,,
My God,, how have we been able to live without this product!!
I'm going out to my gas tank and engine right now and look for damage!!

 

Did the Google. Read through several indy tests. All said no improved results.
Snake oil.

 

A definitive answer, here; LOL.

1) Use Top Tier fuel only and change fuel brands ever-so-often.
2) Use a strong dose of Techron before engine oil changes.
3) Use Stabil if storing for over 3 months.

Everything else is "Snake Oil"

 

Gas costs enough already. No need to add worthless trinkets.
In small engines, 2 years seems to be the storage limit, at least from my own experience.

 

A "mikelikesbikes" sighting, plus a nine-year old thread resurrection - this thread delivers!

 

What specific, measurable benefits have you seen?

 

Dude is banned, so unless he sees this under a different user context, your question will go unanswered (to the degree there was an answer to be had anyway)
