Sea Foam Motor Treatment Fuel & Oil Treatment, 16 oz+14 oz

I removed O2 Sensor and splay about half to 3/4th can to catalic comberter and waited about couple of hours then run the engine with high RPM for about 20 minute or untill smoke disapared from tailpipe to clean. Now my car run like new and very powerfull. Also, at the same time I changed my 2009 Escape Hybrid transmission fluid with original brand(Ford) , Now fixed hybrid battery module problem too and running like new

I threw this pack into a Honda 2003 crv with 101k miles that I recently bought, and it instantly made a difference. it took closer to 15 than 7 minutes to empty my spray can in cold weather, but my motor after only 2 quick drives sounds completely new and has better throttle response. for me personally, this was worth the money

Completely blown away!!! (My husband's review) Have a 2010 Tacoma, 170k miles. Done oil changes and services throughout - taken care of the truck really well and consistently. Have put Seafoam in the fuel tank plenty of times, use it in every small engine too. Was not prepared for how much better my engine would run! Start with a warm motor too. I unclipped a vacuum line, had my wife hold the gas to 2k rpm, and sprayed the entire can in. Heads up, your engine is going to make a LOT OF HEAT while you stand there and spray the can into the motor, took about 10 minutes. Did this instead of hooking the hose up at the air intake of the motor. Can said it should take about 7 minutes, took a little longer. Then I let it "hot soak" for 10 minutes. When you've emptied the spray can into your motor, turn it off and set a 10 min timer. Cranked it and OH MY GOODNESS - white smoke POURING out the exhaust, then blackish smoke that smelled like burning metal. Got in, drove to get the rpm going - would get up to 3k-3500 or so, up to about 60mph - then let off the gas and coast. Did that over and over for about 15 minutes on a 2 lane road. That knocked off a ton... HERE IS WHAT YOU NEED TO KNOW NEXT - change your oil immediately. Either run your truck and drive straight to get it changed, or change your oil immediately. I did this treatment right when I needed an oil change, the oil that came out was black as crude oil. Tons of buildup cleaned off the motor and fuel system. THEN ALSO - drive your truck for 100 miles or so - and change your oil again. I drove mine for about 40 miles and checked the color and it wasn't clear at all, didn't look like melted butter, was brown and dirty. Had to drive about 400 miles for a weekend trip, changed it when I got back and it looked like black coffee. That's how much residual crud was in the system plus whatever else got cleaned off on the trip. Do not miss that added step ^ - commit to 2 oil changes if you get this product. Follow the directions - it's easy. And my 170k Tacoma engine runs as smooth as a brand new Lexus. Not exaggerating, it is wild how butter smooth it runs now.

Add is deceiving, states 3 units, but one of the "units" is a rag. Product is fine, discription should be written more clearly

Ive used this stuff on all my cars for the last 25 years. It does really good. Not necessarily the strongest you can get. If your motor has years of neglect & carbon build up, get something stronger then use this as a maintenance product. Follow the directions

I love this stuff, works really well. I've used it in several vehicles and it worked as advertised.

Used it on a 09 rav4. Cleared some vvt codes. Rough idle went away. 1 month after use and all is good. Will keep using.

It is a reliable product. However, be advised that the Combo pack arrives without the small tube to attach to the spray nozzle on the top engine cleaner and lube can. (That is the way my delivery arrived.) You will probably need that for automotive applications. I have the nozzle so it is no big deal for me. But if it is your first purchase or you don't have the tube and you are using it for a car or truck you won't be able to properly use it. Sea Foam has videos on how it is to be used.
