I jsut read, any fuel injection cleaner can also be used via your intake, to clean combustion chambers ect. Is this true? So that means, one could use redline SL1, MMO, berryman b12 chemtool(toluene), valvoline ,maclife or synpower complete fuel sytem cleaner, Lucas UCL, Fp 60,

via the brake line or throttle body? I would asume, they were more desigend to be run trough your gas tank, tempting idea though:)
 
I think it will be about the same as having a 20 gallon fuel tank full of 5 gallons of gas, to 15 gallons of cleaner. It'll just be a higher concentration of the chemical in the combustion chamber.

Terry has stated that FP60 is a great cleaner when used through the brake line. I used Amsoil PI through the brake line once, and until the cleaner burned completely out, the car would make an awful knock at high RPMs.

I used a mixture of FP60 (2 ounces) & distilled water (6 ounces) and had no ill effects. I had just gotten done with a 17 mile drive with the engine HOT, and had my brother-in-law hold the throttle open while I slowly sucked in the mixture. Engine didn't bog down, and I saw a few puffs of smoke come out the back, and then there were big water marks on the ground from where it came out the exhaust. I then took it out for a highway drive at 70+ mph to make sure all the water/FP60 burned off.
 
I've done MMO through my PCV valve a bunch of times. Probably just as good doing it that way as putting it in your gastank. Makes nice smoke clouds too! I think I'll go do it to my 88 Corolla tomorrow.
 
ziggy,
You shouldn't have any problems with the berryman product, a few others on this site have used it before. Do raise the RPMs a little bit while the intake vacuum sucks it in, incase the engine begins to bog down.
 
Berryman's B12 is commonly used in the manner you are asking about. I have used it many times.

I'm sure that the others you have listed will work fine too, but Berryman's really works well and it is my first choice, just as RedLine SI-1 is my first choice for adding to the tank to clean injectors.
 
Hmmm... what about Schaeffer's Neutra 131 throught the intake?

When I ran a pint of water through the Aerostar intake, I simply poured it slowly into the throttle body. I would think this should give as good or better distribution than a vacuum line as the vacuum line may be off to one side of the manifold.
 
TallPaul is correct that sometimes the vacuum lines may be off to one side. When I put my FP60-Water mixture through the brake booster hose, I noticed a much larger water mark on the passenger side than the driver side.

So it may be a lot better to pour it down the throttle body, I'll try that next time.
 
I never thought of running this stuff through the intake! Wow! Wish their instructions would add that.
So, what does everyone think then. Does running the products through the intake, do as good a job, as it would in the gas tank? And compared ot pouring distilled water into intake?
 
I personally believe it would be more effective as you will get a less diluted mixture in the combustion chamber. Putting it in the gas will keep the injectors clean, so it still has a good use there, and to my understanding, will still clean the combustion chamber, but will take longer.

With water, you are basically steam cleaning the engine. This is effective as well, but you must take precautions to prevent hydrolocking the engine. It was recommended to me to raise the RPMs to 2500-3000 while doing it. Water won't lubricate the upper cylinder area, which is why I did a mixture of FP60 (even though it's been debated whether or not it is a upper cylinder lubricant) and water.

Is there a particular cleaner in general you are planning on using for this method?
 
I just use 2 cans walmart brand tech carb cleaner. 1 can spray in the intake while car is running, the other spray entire contents into gas tank when tank is 1/4 full, drive till its on E and fill up. Thats it I'm done, $2.28 for 2 cans, cheap and easy!
 
Don't forget, you want the engine really hot for the water decarbon process and I would think really hot for any of these cleaners.

What about shutting the engine off while it is inhaling the cleaner, letting it sit for a while (hour, overnight ??), then firing it back up?

you SPRAY the stuff in your tank???????????
why not just buy the bottle you pour in?
 
I'd do a brew of solvents and light oils into the sparkplug holes first, a piston soak. Pour in 2-3oz and crank it w/o spark. That will splash the oil around. When it soaks into carbons, they don't disslove as much as just break off the metal surface. It does something with the rings too. Then do the intake cleaning to clear the valves.
