Default Combustion Chamber Cleaner

Sup guys I have been trippin out about something lately. My friend added some Wynn's combustion chamber cleaner to my car. And he said everything would be fine, but the bottle says "DO NOT ADD TO FUEL TANK" and thats exactly what he did.

I know you're thinking I'm an idiot for letting him do it but hes a mechanic and good friend so I trusted him. Should I be freaking out???

never heard of combustion chamber cleaner, but i'm assuming he thought it was the same as fuel injector cleaners so he just added to the gas. what does the instructions say to do?

probably something like seafoam or b12. yes it most likely is safe in the gas tank.

directions say... "Apply only through P.C.V. system with Wynn's Induction Cleaning Tool"

Maybe it says not to use in the gas tank because they want you to buy more of their product?? lol

I am confused as to why an '07 needs to have a cleaner run thru it

i seafoam my engine quite a bit to keep it running in great condition, i hadn't seafoamed it for about 15k miles and when i did my oilchange + seafoam it ran alot better.

From the Wynns MSDS:
ethyl benzene [100-41-4] <10%
isopropanol [67-63-0] 10-<30%
xylene [1330-20-7] 10-<30%
petroleum naphtha [64742-89-8] <10%
petroleum distillate [64742-47-8] 10-<30%
proprietary additives 10-<30%

Yeah... that probably shouldn't have gone into the tank. This isn't a Seafoam-type product. Seafoam is a detergent pack in a light oil base. This is a 100% VOC solvent. The closest I could compare it to is GM Top Engine Cleaner, which also has a warning against dumping it into the fuel tank.

Corrosion is the concern. Isopropanol is quite corrosive. Ethyl benzene is as well, to a lesser extent. Much like the addition of methanol into gas back in the day (which is specifically called out as a no-no by most auto manufacturers these days because of corrosion), it tends to eat away at the little metal bits in your fuel system, specifically the fuel pump.

Will it destroy your car? Probably not, but I wouldn't make a habit of dumping it into the tank. Plus, you'll get much greater benefits introducing it to the engine straight through the PCV hose instead of diluting it in the fuel.

I'm guessing this Wynns stuff is very similar to the stuff that GM has long time ago. Do they look milky and sticky?

Water is nearly the best combustion chamber cleaner you can get. You wouldnt believe how clean the combustion chamber is with the right headgasket leak.

The same can be done by sticking a vacuum line into a cup of water while keeping the engine running after its been thoroughly warmed up.

Water? could clean carbon build-up???
Never heard of that before????

I've heard of hydrolocking tho.

Yep. If I had read this 6 hours ago I could have even given you pictures. This was on an Audi 1.8t and the two middle pistons looked brand new, the outer two had the normal buildup of crap. I've seen it first hand at least 20 times when doing HG jobs. Its a common gearhead trick to feed water into a running engine to clean up the piston tops and valves.

I'm laughing at you right now. The volume of the combustion chamber at TDC and the vacuum the engine creates means not enough water through a vacuum line to hydro lock unless you tried really hard. Besides remember the engine is running at operating temp and water turns to steam at much lower temps than those of the combustion chamber. I've seen more hydrolocked engines from failed injectors than ingestion of water...

Did you forget about the Subarus on this forum who are using water injection to effectively increase the octane of the fuel and push higher boost pressures?

edit: In fact after a little digging I finally found the car i was looking for - the Saab 99 Turbo S had water injection stock. Many aircraft used water injection to improve performance temporarily sorta like a nitrous shot. I invite you to read this http://en.wikipedia.org/wiki/MW_50

okok, I guess if you do it right with a small portion of water wouldnt hurt the engine. I believe water injection system is a precisely measured system, if you telling me just by unplugging a vacuum hose and randomly pouring water into the cylinder will increase performance, I aint buying that. I've taken engines apart, carbon build-ups are hard as rock. Even seafoam is only good for cleaning up the greasy oil that sticks to the top end, and it's not even 100% efficiency. Water??? I've never tried that, but I could only imagine if I try to clean my greasy stove with plain water........

I swear to you just today (5/22) I touched the piston tops of an Audi and piston two and three looked like they were new out of the box. The head gasket was leaking coolant and it easily cleaned 80k miles worth of crap off it.

Why would I lie?

We used to do this with the old muscle cars all the time. Just would drizzle a cup of water down the carb. while someone else worked the linkage to keep it running. You could almost shave in the pistons when you were done. (Of course you could actually take a spark plug out and see the piston easier then.) RP

Thank you I was hoping some old gear head would give me backup
