Has anyone here had any experience with seafoam engine treatment?

 

not me but I'm going to pay attention. something is just not right to me about pouring a liquid down the intake....lol

 

I've used it on all my vehicles. Works great, once you pour about 2/3 of the bottle in the brake booster line(easiest way and due it kinda fast) you let it sit for 10-15 minutes, fire it up and WATCH OUT!!!!!! Your gonna get one hell of a smoke show coming out the tail pipe. Your nieghbors might call 911 thinking your trucks on fire. It cleans out all the carbon build up on the vavles and such. It's also probably a good idea to change your plugs afterwards although you dont have to.

 

My fear is the cat getting plugged... but I have used it in the fuel system. Whats your guys thoughts? I have seen it dumped the way you are talking about. It looks like a fire and its hilarious. My buddy did his Civic Si once... talk about SMOKE!

 

I did my truck, and got nothing lol, not the tiny bit of smoke. I thought, Maybe not enough KM, try again later.
I had it to actually do the 2000 3.7 CC I had before my 05, it had 165,000 km

 

What is the point of doing this again?

If the engine is well maintained, why does it need to be cleaned out? On an older engine, couldn't this cause potential issues?

 

I heard older ones can develop issues when its cleaned.
Im the 2nd owner of my truck. I dont know how well it was kept before I bought it. haha
Lady almost didnt sell it to me. Her words where "If it was a nicer truck, I wouldnt sell it to you." Note its only a ST to.

 

The problem is the damn ethanol they are putting in the fuel, it leads to more deposits, not to mention eats the sh*t out of rubber, seals, lines, etc. That's why a vehicle has to be built with all different fuel delivery components to be certified to run flex fuel (85% ethanol). You'll notice the trend for all the major oil companies to advertise "detergents" in their gas, this is to clean up the mess caused by ethanol.

I was having to replace the primer pumps and fuel lines in my yard stuff YEARLY and rebuild the carbs about every two years and I NEVER had to do this in pre-ethanol gas days!

I SeaFoam my gas once every 3000 miles and I put 1 oz. per gallon in my yard equipment and ATV gas as soon as I buy it. I do the intake thing about once a year. I don't use it with my oil in the crankcase.

I also used to put TCW3 (boat engine lube) in my gas in my truck and Jeep at a ratio of 1 oz. per 5 gallons of gas and gained about 2 mpgs by the third tank I did this on. It makes up for the lack of lubrication the ethanol "steals" from the gasoline. The only reason I don't do this anymore is that I now buy all my gas from one of two stations in my area that sell NON-ETHANOL gasoline.

I get the same roughly 2 mpg increase using non-ethanol that I got when I put the TCW-3 in the 10% ethanol gas.

I can tell you first hand, the crap you hear about the TCW-3 fouling plugs and clogging cats is BULLSH*T, as a matter of fact, my plugs never looked better than when I was running TCW-3 at a 1 oz. to 5 gal. ratio...

 

It only develpos issue's if you put it in the crankcase to clean out the oil passages. Despite what that directions say DO NOT put it in with your oil. It will eat away any of the build up the oil seals which in turn cause it to leak. There is a thread like this on a jeep forum I'm on and it's probably 50 pages long with more good then bad (90%good vs 10%bad) stories about seafoam. As with any product there is always going to be some negative things about it. BUT this stuff does a decent job if used properly.

 

Not babying your stuff will help prevent carbon buildup in the first place. My friend bought a 4.0 Ranger that pinged very baldy, it's original owner was an old man and the person he bought it from was a one-armed lady (the truck is a 5 speed) so it wasn't getting driven very hard. After a couple of Seafoam treatments the pinging was GONE! And he drives it hard so it hasn't had an issue with carbon buildup since. I once did a treatment on my truck and didn't really notice any difference, but it wasn't pining or anything to begin with.
