So a few problems I experienced with this product. First, I doubt that this is an isolated issue, I found it incredibly painful to keep it spraying for 7+ minutes in order to empty the content into the throttle body when 1. Itβs hard to keep it pressed down for that long to begin with but 2. The location of the throttle body manifold and the fact that you have to get the car to operating temperature means that you have to keep your darn hand 7-10 minutes right over or near the cooling fan. This means that every 45 seconds or so, you get a nice blast of volcanic heat on your fingers for 20+ seconds. It was really unbearable. Second, it is pretty difficult to spray this thing in an upright position so the aerosol is blasted out before the full content of the bottle. I was able to use about 607-70% of it in my estimation before the aerosol ran out. Lastly, be prepared to let the car sit for longer than the 10 minutes that they suggest. I had to take the car home afterwards and the engine was doggin it all the way home. What is usually a 15 minute ride, took me 35 minutes with people behind me cursing me up and down. I thought I might of had some spray back into my MAF sensor and that was causing a poor air to gas mixture ratio. But after I took my wifeβs car to the autozone and got some cleaners to take it to task, I came home to move the car and it ran fine. That was about 3 hours after the fact so I donβt really know how long exactly it would take you but I read online a bunch of people experiencing the same result. Now, My intention for using this product is to solve my problem of oil burning off in my car. Honda Accords had an infamous issue with the piston rings getting stuck and burning oil. In fact they had a service memo out on these vehicles to fix the issue for you for free, I missed that memo. So, I will come back and re-rate this product based on whether that issue improves or is resolved.

I’m rewriting this review weeks after my first use of SeaFoam. My first review was about the smoke, the car running smoother, etc, etc… The normal stuff. As of now, this product has done so much for both our cars…I see alot of debate online about its’ effectiveness. People either love SeaFoam or consider it “snake oil”. They also criticize saying the smoke is actually the product burning off, not carbon. To the smoke part, I say what difference does it make?We have two high-mileage cars. A 2009 Jeep LIberty with 143,000 miles and a 2013 Kia Forte with 94,000. The Jeep has had its’ Check Engine light on for almost a year – P0430 code, “Cat Inefficiency, Bank 2.” The timing chains and guides have been replaced along with the Thermal Intake Sensor (what Jeep calls the MASS Airflow Sensor), MAP Sensor, and EGR valve. The car has been through alot, running very rich for years as we worked out problems and I lived near the ocean for a long time so I began to accept the Catalytic Coverter was history from abuse and salt. I did run CatAClean through (not cheap), cleared the code repeatedly and the Check Engine light just came back on. I tried Techroline (and others), and SeaFoam in the gas tank, same thing. Two shops handed me $2,200 estimates for an entire Catalytic Converter Y-pipe because the second cat was sure to be next. I’ve also been told all along that the Jeep’s motor looks all carboned up on a scope.I ran this product in the intake, did the whole hot soak and smoke thing, cleared the codes, and the Check Engine light has stayed off for weeks! It never stayed off for more than a day before; returning the moment the car got hot. No more P0430 code for the first time in almost a year and I’ve driving the hell out of it!!! I wasn’t even trying this for this problem, I just wanted the idle to smooth out… this was an unintended consequence and is saving us $2,000 because had the light stayed on, I was going to have to replace the cats just to SMOG It. I couldn’t even sell it if I wanted to.Now the KIA… we’ve had problems with the car pinging LOUD on hard acceleration. I hadn’t tried much to remedy it but it was getting very bad. I figured I’d deal with it at the 100K tune up.But because of the experience with the Jeep, I ran this in the KIA’s intake and let it hot soak for fifteen minutes – really out of curiosity. When we started it back up, there was no smoke – NONE. For miles nothing and it was still pinging! Then all of a sudden on the freeway accelerating, the car kind of paused for a second (which scared me a little) and suddenly started blowing blue smoke out the back – making it difficult to even see the car behind. It gradually recovered and the pinging was completely gone. It idles so quiet now I have to keep checking it is actually running.Just like everyone, I’ve wasted so much money on miracle cures hoping to luck out. It never happens. Honestly, I’ve run a lot of regular SeaFoam in the gas tank and it never seemed to do anything. (although I just ran it in the oil and yes it really helped). But this product is really great. Chrysler sells something identical (for $40 a can) and the guys at Valvoline said they have theirs too. It seems safe for the car as long as you keep it away from your MASS Airflow Sensor.I probably won’t use it on the Kia again for a very long time but I’m going to incorporate this into my normal 30,000 mile tuneups on the Jeep. I think many of the people who consider this “snake oil” are people who had more serious issues the than product could help with, or never had any problems at all and expected there to be something spectacular. What I’ve seen are very real, tangible, quantifiable results and a major repair bill narrowly avoided.

Thereβs numerous videos on YT showing legitimate results (e.g., Project Farm). However, I used this on my 2014 Craftsman Lawn Tractor with a 19hp B&S engine. I noticed carbon build up on the piston and in the chamber (used borescope). I decided to clean up the combustion chamber when I did the next tune up. I followed the directions to a T. Smoke was suppose to come out of the exhaust as it burned off the carbon deposits. When it came time to mow the next time, it continued to bellow out white/gray smoke. It would burn oil the entire time until the level was past the dipstick. I thought it maybe it was still clearing out the deposits. It did for a year. Iβve changed the oil every season. Always did a yearly tune up. I decided to remove the cylinder head which revealed a blown head gasket. The βknockβ from spraying the cleaner through the carb apparently detonated enough to burn a hole in the head gasket. Oil would pour from the pushrod/lifter valley into the combustion chamber through the blown out section. Now this product has worked for other people. Just proceed with caution.

When I first opened the air intake, it was dirty and grimy, so I cleaned it off with paper towels. Even with that, after spraying the seafoam, the intake looked like it was new. Not only was it smooth, but it also had a rich color and was nicely lubricated. It’s an absolute must have.My only complaint is that you’re going to need a second person. Holding down the spray button is really tiring and after 8-12 minutes of holding it you get tired of it. Sure, you can just tape it down, but you want to keep the can away from heat sources, so someone should really be holding it.The second problem is the RPM. The manufacturer states to keep the engine at 2’000 RPM while spraying, and in my car at least, the position of the throttle control and the air intake would have put me right over the spinning fan blades.So, you want someone in the cabin holding down the throttle and you might want to switch hands and be ready to hold it in place for a while.But gosh darn are the results worth it.
