Sea Foam and CNG?

[EdWaRdW818]

Hi:

Since my own car (gasoline) worked wonders when I made a complete Sea Foam treatment (e.g. 2 bottles with 3/4 brake booster, 1/2 crankcase and the rest into the tank), I was wondering if Sea Foam is safe for CNG cars... I know you obviously can't pour that or other additives into the CNG tank, but I have a some questions:

1. Are you able to Sea-Foam a CNG car?

*The following questions only apply if #1 is "yes"
2. Aside from again, not putting it into the CNG tanks and common sense stuff like not doing it in a closed garage, is there any precautions that should be taken?
3. If anybody has tried it, is the difference significant enough to warrant Sea-Foam treating a CNG vehicle, or have any side effects?

Thank You,

Ed

I hope someone can answer this for all of us. It works wonders to get rid of check engine lights and improve performance, but other than the crankcase and the gasoline tank, how could the cng system get flushed?

I had a fuel system cleaning done on a dedicated Crown Vic and Ford's ingredients for their flush kit are similar to Seafoam. But I don't trust myself to work on Fords, I'd probably make matters worse.

LOL yeah... The car in question IS a '91 Ford Taurus.

If you think about what a fuel system flush does, which is clean the valves and interior ingine parts of carbon build-up, then there would be no real reason to do this on a dedicated vehicle. The lack of carbon in the engine is a key benefit of CNG. On the other hand, a bi-fuel vehicle that see's some use of gasoline would stand to benefit from a periodic cleaning. In a bi-fuel vehicle the cleaning process would be the same as on a regular gasoline vehicle.

Oh OK... I just haven't taken apart his car to see, but 1. According to the previous owner, the car was ran on gasoline for some time before it was converted to CNG, 2. there might be some dust build-up that could've been missed by the carburetor filter, and 3. I'm also kinda trying to figure out a throttle response issue on his car; my car's throttle response went from barely functioning to the throttle response of an Italian race car after I Sea-Foamed it.

But my main concern is: To do this on a pure CNG vehicle, is there any volatility issues? I don't want to pour it into the brake booster line and have the engine explode on me or something LOL.

Thanks for your help!

Even the dedicated Fords get dirty from time to time. There's a TSB and a special Motorcraft solvent used to clean out the injectors.

The problem with bi-fuel is that many don't have a vacuum line to the brake booster going only to the intake. So for those, you'd have to pour into the throttle body.

what is sea foam?

It's a liquid that cleans out the engine.

As in the intake's vacuum line, or actually spraying it in through the butterfly valve?

Re: Sea Foam and CNG?

you can fill the CNG filter bowl with it, but I think it has too much oil in it for these injectors. if you use seafoam you should follow with an alcohol type injector flush, like Motorcraft injector flush.

Re: Sea Foam and CNG?

Sea Foam works great on CNG vehicles. We take the CNG filter off and fill it 1/2 way with Sea foam then dump the rest in the gasoline tank. This will help with a stickey CNG injector. I have not had any problem letting it pull into the vacume system on a 01 GM 6.0. We use it on every thing. It is magic. As a mater of fact I am doing it to a truck this week end....Mine.

On a duel fuel, I guess. I'd rather have the injectors removed and cleaned off the car myself.

Tom,

Have you ever used seafoam in the filter bowl on a Civic GX? I am wondering if the injectors and regulator would be too finicky for running it through them.

Re: Sea Foam and CNG?

We use it on our bi-fuels works great.

Re: Sea Foam and CNG?

If I'm going to add sea foam to the filter bowl, is there a way to shut off the gas at the tank so I still have some gas to run the seafoam through the system after I fill it? I have an 02 Chevy Silverado C2500. I don't want to be smoking like crazy at the fill station.

Re: Sea Foam and CNG?

Im new to CNG vehicles but my brother-in law uses sea foam on his company trucks and swears by it. Ill be adding some myself.
