I tried a lot of things and not many worked as advertised.

Water works, but you have to use a lot of it and you have to use it for a long time to clean an engine.
It has the potential to do more harm than good sometimes.

A chemical company in Montreal made some stuff called CV-100 you mixed in your fuel it worked too ( after miles of driving ), but it also clogged all your filters and parts as it cleaned everything and it worked so well cleaning the fuel systems that today I am scared to think of what might be in it...
MY GOD it cleaned things, even removed the paint from your fender.
The inside of diesel engines were shockingly clean after a few hundred miles of it.
Seems to me your fuel economy improved too.
And it turned your nail bed a funny green colour and dried out your skin real bad if you got it on your fingers...

Loctite gasket/paint remover works.
But you have to pull your head off after you spray it in the combustion chamber and let it soak overnight.
Then the carbon come off like old paint... exposed to paint remover....

Nothing I have seen you pour into a running engine seems to do much.
At least not with one treatment, but non of it seems to do any harm....
Anything that does work well comes with risks.

there is the xyl*** (fill in the blank) in the fuel. Boosts octane and cleans exceptionally well. but don't want to be around the exhaust pipe when you do as its toxic to humans the gases it puts in exhaust. Instant casket!

I did a thread on cleaning combustion chamber using just about all products recommended and some never thought of including human piss. None cleaned better than removing the head and doing a good old fashion cleaning using elbow grease.

If the Onan 4C is anything like Delco X66, it works great for cleaning out carbon. Look at the back and see what it is in it.

There is already Xylene in gasoline, these are products from the crackers and reformer, but they are expensive so Mogas does not have a lot of them.
100LL however is loaded with the stuff.....

I used use Xylene as a co solvent to blend with methanol and other products in my racing fuel.
The ring hydrocarbons do a very good job of devolving one thing into another thing and keep the mix together.

When I worked for Cummins/Onan, i carried a few cans of it in my service truck and used it regularly.

Good stuff and works well. BUT....... Read the directions before using it and follow them for best results.

Most of my service work was on large commercial equipment, used it there at times too, works well on diesels too that had been wet stacking and were badly coked.

For loose carbon that sounded like a piston knock, dad would warm up the engine. At idle pour 1/2 a spray paint cap of gumout? down carb, then suddenly dump rest down it. Then if engine wasn't stalled yet, quickly shut off engine. Sometime next day he'ld run the car and knock was gone. Guess the stuff softens the carbon and allows it to break up and blow out the exhaust. Sounds like it was de-carboning the cylinder also.

Don't remember well, but he may have also used marval mystry oil instead.
