Combustion chamber cleaner recommndations

[Pablo]

I think Fuel Power Works pretty good as a combustion chamber cleaner. I also think Amsoil Power foam works well.

I'm not telling you to do this, but I use FP a bit stronger than they (LC/Otis) recommend if the car has heavy deposits. A few ozs of anything in 20 gallons of gas is not going to blast 250,000 miles of cc deposits.

Also, it takes longer to clean than the miracle claims. A high mileage car with lots of deposits didn't get that way in 15 minutes and it's probably going to take longer than 15 minutes to clean!

I also second careful use of direct ingestion....I have seen water, various OTC solvent solutions, Amsoil Power foam directly sucked in, mosquito fog out and clean cc's (visible with borescope) result!!!

Or you could just get it done properly and professionally at a fuel injection specialist.

It's marketed as "Carbon Clean" here, but I'm sure it has other names elsewhere, it costs a bit more, but nothing works as well, or is as proven to work on high mileage cars.

I remember cleaning my motor, just running the hose all over it unconvered. this was a 92 seville, 4.9 engine

I started it, and it had white smoke for a few minutes driving around! I think water got in there. The idle was REMARKABLE smoother for awhile!

Fuel Power. A "kinder, gentler" combustion chamber cleaner.

My girlfriend's Explorer was knocking like a tea kettle under WOT from the carbon deposits in the combustion chambers. 3 tanks of Fuel Power later, no trace of knock is left, even after running a couple of tanks with no FP in them. The stuff flat works. I much prefer it to "shocking" the deposits out of there...

I have used FP in four vehicles. In the three higher mileage, V-8 powered vehicles, the idle was considerably smoother, and was much less harsh. I know that subjective. I attribute that to a cleaner combustion chamber, whether right or wrong. The fourth vehicle is a 2000 GMC Sonoma, with a 4 cylinder, which is a buzzy engine to begin with, hence I notice not much difference.

I'd actually attribute it to reduced intake valve deposits...
