My logic was, if it was water, it would surely freeze now, and the thing would either run better or not at all.
I took it out early this morning and it did run better than before. But, it did still miss a time or two
Anyone here use SeaFoam?
It says 1 oz per gallon of gas... I'm doing that.
I'm also thinking of trying to find a way to direct feed a pint into the injectors. I just haven't been under the hood yet with that in mind to figure out what vaccuum line I can use to suck it in.
If it were water, it would settle at the bottom of the tank, but may not freeze!
I've used seafoam for about 15 years with great success with one exception, sadly that one exception was my sporty. As the seafoam burnt off it 'confussed' about all the sensors on the sporty and triggered a few CEL's but nothing that wasn't cleared up by resetting things (either by using a code reader or un-hooking the battery for 10 minutes)
To correctly use seafoam, pour 1/3 of the can into the tank, 1/3 into the crank, then take a length of vaccum hose and hook it up to the vaccum port on the intake manifold, put the other end of the hose in the seafoam can with the remaining 1/3 in it. Now start the engine, the seafoam will be drawn into the intake manifold, it should stall out, if it does let it. If not once the seafoam can is empty shut the engine off.
Now wait 15 to 20 minutes. start the engine it will be sluggish at first and create a huge cloud of white smoke, so close the doors and windows to your house and warn the neighbors. Seriously there will be alot of white smoke. The smoke should start getting less and less and will take 10 to 20 minutes to totaly clear up, although you may still see traces of white smoke for a while after in the exhaust gasses.
Once the engine stops pumping out most of the white smoke the engine should be nice and warm, shut it off and change the oil, the seafoam that you put in the crank would have removed most of the carbon and varnish build up in the engine and oil, so you will want to change both, remember to change the filter.
The seafoam you put in the tank will run thru in time, and should remove any water and build up in the fuel lines and injectors.
Like I said I've been using this stuff for decades and this is how I use it, I have used it on Cars and trucks from the 40's, all the way up to todays cars. Everything from everyday drivers, to 60's Mopar muscle cars, heavy duty trucks and small high reving sports cars. It also works great on lawn mowers and snow blowers, basically any 2 or 4 stroke engine.
You can also go to the seafoam web site they have a video on how to use it on both fuel injected and carburated engines.
