Carbon Buildup...Removal of said buildup and main

[Da Game]

"If you are really concerned about this, then maybe once a month add either Seafoam or 12 ounces or so of transmission oil to one tankful of gas during fill-up. I personally add a few ounces of ATF to every tankful. This will minimize CC build-up and promotes ring and valve guide/seat lubrication."

The above was posted on another site. I was wondering if this is reccomended by you guys or is this a NO NO... Some has suggested the Seafoam method added regularly. I was thinking one of the LC & Auto-RX products will work better. This is the first I heard of adding trans oil in the gas tank. Suggestions please.

The ATF thing in the tank is old school. The problem with that old school thinking is that there are things like oxygen sensors and catalytic converters to poison nowadays. I wouldn't be putting ATF in my tank.

The seafoam seems to be okay. I've use Chevron Techron additive, Duralt, and my recent favorite is FP3000 and FP60 (can't get the FP3000, but you can still get the FP60).

It would seem to me that adding oil to your gas would create a problem with deposits on the top end, especially in a DOHC engine. Not to mention shorten the life span of your gas filter and O2 sensors.

If you must use a gas additive to assist in keeping injectors clean, i would use valvoline synthetic gas treatment. It's the only gas additive i've ever used that i felt actually did something positive.

WOT acceleration to red-line is the most fun way to keep injectors clean in my opinion

Pure BeeAasss!

ATF in gas tank is downright stoopid, esp. these day and age where there are sensitive, O2 sensors pre and post cat convertor downstream, and most automanufacturers have to swallow a lot of warranty and emissions compliance by honouring/warrant a lot of emissions components for 8~10yrs and one screwup on any of these sensors will pretty much brings your car to it's knees.

If you want (I personally against these, citing the "so-called" benefits from old-schools), you can try Lucas UCF or MMO but I doubt if that's gonna do you anything.

If you want something in a long run that would keep your fuel systems clean and trouble-free, consider using FP3000.

IF you are the kind of person like yours-truely that constantly monitors and maintains his vehicle in tip-top conditions and only need some "helper" additives once in a while, Pennzwax's Regaine and Chevron Techron concentrate get my votes.

Also: WOT accelertation to red-line will not keep your injectors clean BTW for your injectors only runs on full-open pulses and nothing will remove those organo metallic deposits other than proper FI cleaner or ultrasonic cleaning with liquid FI cleaners.

acetone baby!




... at 0.23% by volume

MMO religiously in the gas. Keeps the motor CLEAN and
have never had a cat or O2 sensor problem

Water treatment.

Fix the causes of the carbon. Otherwise, you'll need to constantly use a band-aid that has negative side-effects.

Seafoam appears to be mainly Naptha and Pale oil, there seem to be a large number of products with these ingrediants. MMO would seem to be very similar, seems you could mix some that would be way less expensive. If I'm going to spend as much on a can of seafoam, Techron or Regane seem like better buys for the PEA ingrediants.

Chevron Techron, and better yet, BG44K are the only products that I know of that actually work to remove carbon from the combustion area.

jmac-

naphtha, stoddard solvent and the likes are mainly being used as a "carrier" agent that eventually gets burned along as the chemical does it's work.

Casually mixing up some stoddard solvent and "carrier" agent in hopes if it will does the job (sans the secretive ingredients) will not get the desired result, period.

manufacturers will do their best to hide their trade secrets from prying eyes/competitor's reverse-engineering, and the only thing that they are willing to release out in the public in the MSDS section are mostly just common chemical ingredients. Don't expect a weekend DIYer or backyeard engineer can get the same kinda results by simply copycat the MSDS sheets...

My 2c's worth

What? Don't burn gasoline or diesel in your engines?

I guess we could all convert to natural gas, but even it produces some carbon when burned.
