This is a request for information about the use of de-carbonizers (gas tank added liquid.)
The first time I ran into this was when I bought a used boat and the previous owner said I should add so and so much of that stuff from the little bottle (which he supplied) every few tanks or so; it would keep the engine clean.
That boat has a 70HP 3-cylinder 2-cycle engine (with automatic oil mix.)
Now I have repaired the generator and and the question arises whether it might be a good idea to use it there also since carbon build-up seems to be unavoidable.
My question is triggered by some statements that don't quite mesh.
First, it is not sold as de-carbonizer, and I don't have fuel injectors in boat or generator.
What I bought seems to be the middle line of agressivenes and is called
GUMOUT (concentrated) Fuel Injector Cleaner.
Claim: "removes carbon build-up."
Salesman (Autozone) advised against higher strength version of the same stuff "because it burns too hot and therefore wouldn't be good for aluminum engines."
Other brands are also available (STP)
So my question is: who has any experience with this stuff and how does it work?
Is that hotter-burn true?
Some of these bottles claim their contents will PREVENT carbon build-up; this one says it will REMOVE carbon build-up.
Another one stated "contains jet fuel" (????)
