Correct, I have never had a reason to try it. My vehicles magically stay running perfectly well without any exotic concoctions through the miracle of regular maintenance.

But then, what do I know? Obviously I'm clueless about building and modding RX-7s, as well as keeping them on the road and running reliably.

 

I think that there may be more of a benefit on older cars, which lack the tight fuel control that the newer cars do. Maybe running a carb results in faster carbon buildup.

What I do know, is that in my carb'd '85, you can feel an increase in power within minutes of adding a bottle to the tank (assuming it hasn't been treated in a month or so).

Maybe in a FD you wouldn't really notice anything like that...

 

Well, I should know better by now than to get involved in religious arguments like additives. My own fault for opening my big yap.

 

Hardly a waste of time Aaron , It is important that people state their opinions + or - so that our members and visitors can make their own decisions on any matter .. What bothers me is it seems like no matter who says what , someone doesn't like what they hear and get all pissy faced . About every week or so or it is either Seafoam or Alumiseal . The same old **** in the same old pile .. There must be 100 or more threads on both subjects and good informative threads .. Why keep pulling the dogs tail ?? Possibly the main players in these subjects could point new folks to the search area and let them make their own decisions without the conflict and repeated irritation. Remember God grant me the serenity to accept the things I cannot change , to change the things I can and the wisdom to know the difference.. IMO most additives suck but there are some products that do work if only temporary , PLEASE You gentlemen are far to valuable players to waste your time bickering .. Like you could spend some hair pulling time teaching me how to set up my bike with the very bare necessities for fuel injection !! With all due respect to everyone .. Gerald m

 

lol, kinda like asking if Blondes or Brunettes are better.

 

I don't think I'd try this?

 

yah i wouldnt either seafoam is SKETCHY

 

if any of the folks wanting to clean up their fuel system and fuel system deposits have tried BG 44K.

It seems like Seafoam is the "Forum Favorite", perhaps because BG is not sold in parts stores, I dunno.

I do know I would not be wanting to use a product that claimed to clean fuel systems, AND oil systems.
Fuel deposits and oil system deposits are very different from each other and require completely different chemistry.

The "smoke show" typical of some fuel cleaning deposits is primarily steam from a glycol base. Not much cleaning going on, and if it is, it's not the kind you want.
With steam you are basically taking huge chunks of carbon off, shocking them free to go where? Straight to the catalytic converter is where.

That's why we no longer pour water down a carb; back then there were no cats or O2 sensors or any type of emission control system for that matter that would now get wiped out from a water douche.

A good reason to run a professional product through the fuel system periodically (10k miles) is to keep the carbon knocked down to as close to "factory new" as possible.

Octane Requirement Increase is something that (over time) will happen, unless you are running 100 Oct Unld, you will get fuel system deposits from any brand or grade of pump swill.

Full disclosure - "This guy" sells this stuff 5 days a week.

 

I've seafoamed all my cars. Love the stuff.

 

I heard it was bad in rotaries...but I feel like I want to give this a try. I'll be swapping a TII this year anyways and the engine my car came with was RIDICULOUSLY neglected. Thanks for the info, everyone!

 

On the contrary, Sir. I took an automotive introductory class at college and the instructor specifically said that all vehicles need injector cleaner every oil change.

I am still skeptical about putting anything in my rotary but carbon buildup generally is not good for engines. With a Rotary engine burning loads of oil on purpose, I would imagine there is quite a heavy amount of carbon buildup.

When I disassembled my 6pi system to clean it, It was very gummed up and took a ton of carburetor cleaner, clean rags, and q-tips to clean. I was premixing the oil 100:1 ratio with 2 stroke marine oil but it looked like it had been accumulating for a long time.

 

This thread is two years old or so but now it is open again I have a story about sea foam from this winter .. Snowblower of course they sit for long periods of time with out running . My blower finally got to the point where when it was working a bit would just quit couple pulls it would start and go a bit more . finally went to town and bought a can of the **** and poured about 1 OZ. in the tank less than 1 gal. of fuel . started it went in for coffee left it run about 1/3 throttle for 20 minutes , went back out and blew snow ,, it quit twice the rest of the job . when finished I filled it with fuel and added about another 1 oz. (( just poured a little in then added the fuel . the next time I used it it quit a couple times . by the time I burned 2 gals of fuel it ran like new ,, needed to take carb apart again to reset float after screwing with it before the sea foam .

i have never been a believer of additives because most are useless but yes seafoam does work for plugged up carb passages and what not , but it's not a miracle product that fixes things but if things are plugged up in fuel systems it seems to have the ability to clean the internals . Mostly you will find that it is the petroleum distillate in the product that has the ability to dissolve fuel related varnishes etc.

So my apologies to Kentetsu it does the job for neglected and plugged carburetors and so on as far as fuel injection is concerned I know or have had nothing to do with . But no it won't fix a fuel tank full of dam rust .

 

Every can of Seafoam comes with Mini Magical Mermaids that scrub the internals of your engine Making the engine feel all Giddy and fabulous.
Only THEN does the owner notice that the car has a new attitude but the tendency to backfire small fish that talk like Ellen Generous..

Actually I like the stuff..I tried it years ago in addition to flushing the fuel system out..After I had pulled the pump,changed the filter(s) and cleaned the injectors.I figured it would help with the stuff I couldn't see.

 

Hey mister have you got a couple extra of them mermaids ?? all we have around here is bridges with trolls snapping at my butt .

 

Man that's good to read. I talked to a rx7 guy yesterday and apparently it actually is best to get the "Magical Mermaid" Bottle with the vacuum plug to run it through vacuum. "It will suck the whole bottle up by itself and go directly to the engine."

Honestly though I am trying to find an additive that will effectively clean my catalytic converter. Here in California smog rules are extremely strict and I have been fooling around with this car for months trying to get it running correctly.

Has anyone tried Mr. Gasket Cataclean on a rotary? It is supposed to clean Oxygen Sensors, Fuel Injectors, And Catalytic converters. It is a complete fuel system cleaner as well. I am still unsure about using Ethanol from the race track to pass smog. It sounds like it could really hurt the car.

 

IMO Seafoam is snake oil, promises the cure to cancer but gives you the flu. You are better off doing the water injection treatment, it's nearly free and hurt nothing when done right. Seafoam is just an alcohol and petroleum blend. I have used it once but I don't trust additives nor fuel injeector "cleaners"

 

What is the water injection treatment method?

 

You can refer to Aarons website, but in short the idea is to have your engine fully warmed up. Choose a vacuum hose that does the best job at evenly distributing water through the front and rear rotor. Use that vacuum line with an extension to allow your car to carefully ingest small amounts of water through the intake manifold. The water will hit the rotor and flash steam, the resulting pressure and moist environment breaks down carbon cleaning your engine from the inside. This method has helped me cure idle and misfire problems in my GTU.
