Wont hurt.
Get ready for some smokeage

 

I've never used it to get rid of carbon, but I've heard it's very good at that as well. I've used it to unflood cars before. Last time we couldn't get my friends 12A to start, poured about half a bottle between the 2 rotors, started it and it filled my entire neighborhood with smoke.
It looked like a big warehouse fire. Fire dept came, one of the firefighter guys was laughing the whole time, he finally came up and said: "I had an RX-3, you guys still using ATF?"

 

Thats a pretty damn funny story...

now for the obvious novice question...

WTF is ATF? And what do you mean you poured it b/w the rotors!

I hate all these damn acronyms!

 

Automatic Transmission Fluid

use the search function bro

 

Are there any chemist here that can tell us WTF ATF does to carbon build up?

 

Burns it off! Chuckle chuckle chuckle.

 

I have been using Marvel Mystery oil as a Pre-mix in my gas tank. If you look up the contents I believe its basically ATF with other ingredients. It does put out a slight bit more smoke than say Pettit's Pre-mix....But it's not very noticeable.

 

What's the scoop on ProtekR from Pettit?

Is it really good?

My engine was just rebuilt and when I ordered parts from Pettit they included a "sample" size for one tank fillup.

Are they just trying to make some cash, or is it really better to put this stuff into the gas tank?

 

What is that stuff for?

 

Hmm maybe I'll wait on doing the ATF trick if Marvel's Mystery Oil does the job...I've been using that stuff for a while now and my engine runs silky smooth, I always put in 4 oz with every 10 gallons. I never noticed smoke whenever I use it (in the gas tank)

 

This reminds me of the carb cleaner that I use to clean out the throttle body/intake off piston engined cars. Here's a question, will the ATF fluid work the same as carb cleaner IF I put the ATF into the engine through the throttle body? Logically it seems the same. The carb cleaner dissolves deposits too so...will it work with the piston engine?

 

how much do I put in for a tank full?

 

OK, so back onto the ATF topic..I'm gonna be changing my plugs and wires this weekend. Should I pour some ATF in? Should this be a part of basic maintence?

If so, any particular kind of ATF?

 

from what i've read, it doesnt matter...the cheap stuff will do.. just pour it in, crank it, pour in some more, crank it again and then let it sit

2nd Gen Forum goes into it

 

I'm sure it wont hurt anything, god knows I've unflooded many a 12A with the **** and they all run fine. I'm just not sure of the gains you'll see.
I've heard it removes carbon deposits but to what extent I dunno.
This would be a good question for the big list.

 

Here's the links for anyone trying the ATF trick.

Only did this when the FD was flooded, I'll try it this weekend and post any observations.

 

I remember someone stating that .....to perform the ATF trick, just pull off the hose from the upper intake manifold that goes to your boost controller and place the end into the ATF bottle. Now just start the car until it dies. The engine vacuum will suck in the ATF. Let it sit overnight. The longer the better. Reconnect hose and start it up. Make sure you do this outside. Lots of smoke.

Hmm.... so it's safe to just pour ATF in your engine.. and it helps it.. I may have to try it?? You're positive it won't mess it up??
Thanks

DO THIS AT NIGHT, I REPETE, DO THIS AT NIGHT! WAKE UP YOUR NEIGHBORS IF YOU MUST. YOU DO NOT WANT THE FIRE DEPARTMENT, LEAST OF ALL THE POLICE, TO COME TO YOUR HOUSE.

 

ATF is primarily for older engines that have been sitting. You see the biggest difference on the older 1st gens because by design and because of age they tend to have more carbon buildup (not many 3rd gens have 150K miles am I right?).
It works because ATF has chemical detergents that will dissolve carbon if given enough time to work on it. The carbon gets stuck behind the apex seals, by the springs, and over time it can cause the seal to get stuck inside the groove and you lose compression. Dissolve carbon and restore compression and power. Simple as that.
I don't think 3rd gens really benefit much they are, umm, "cleaner" engines but give it a try. As with any DIY use some common sense.

 

Can anyone confirm that this is a safe alternative method to put ATF in the system? Sounds kind of screwy, but also a lot easier than cranking and reapplying to each leading plug. The plugs will need to be changed no matter what...just a few less steps

 

this is a very old trick to help "build" compression in an old motor to help get it started. in carbed cars you just dump it right in the carb. in FI cars, i always used a turkey baster and shot a squirt into the spark plug holes.
i dont see how putting it through your TB would hurt anything, but i also dont see how it will help.
Do you people realy think this is good for regular maintence? why use it if your car starts? and how much are you guys using that the fire dept. is coming to your house. a few drops is enough for the whole engine. i always have more than 3/4 of a quart left over when i do it. i drop a bit in, crank, repeat about 3 times to ensure it gets to each chamer. smokes...but come on! fire dept? jesus christ? how much do you use?
oh and pettit proteck R is just a Polaris jetski synthetic 2cycle oil.
