Sea Foam Motor Treatment Fuel & Oil Additive, SF16, 16 oz, Pack of 12

This fuel conditioner is hands down the best choice of any. I have run it in every single vehicle and motorcycle I have owned. Treats fuel for storage, and cleans your engine and keeps it running smoothly and efficiently.

I've used Sea Foam for years in all of our vehicles. Always for preventative purposes but had slacked off. My F150 started skipping/missing when I accelerated onto the interstate. Dirty turbo injectors. I ran the Sea Foam through my truck in two tanks of gas and the problem is 95% eliminated. Just ordered 12 more cans and will treat the truck again when those cans get here. My truck has 177K miles on it and never had any engine issues. Am sure this recent issue wouldn't have happened had I used the Sea Foam just a few times. Anyhow, this stuff is magical. Definitely try it for engine issues, or just for preventative care.

I have been adding Sea Foam to my gas about once every two months or whenever I am taking a long road trip, for a few years now. It has kept my car running smoothly and clean. You would actually hear your engine running quieter after you used this for the first time. I have been recommending this to family, friends and colleagues and every time they came back to me testifying how much better their car is running. One good friend had bought a used car and found the engine cutting off when idling. After using Sea Foam once and taking a long drive, the car has never again had that problem. It saved him hundreds of dollars if he had gone to have that fixed at a mechanic. Highly recommend it!!!

Great product

However....tends to drop your mpg about 3 miles. Ish. Use it every other fill up.

I been using sea foam for many years and works wonders in my car engine oil and gas tank. I also add it to my lawn mower and snow blower. It keeps the gasoline fresh and keeps the engines clean. Going back to adding it to my engine oil: A few hundred miles before I am going to have an oil change, I add approximately 3 ounces to the oil. I continue driving my vehicle on a daily basis. When it’s time to change my oil, it comes out super dirty. ( this is by design and you want your oil to look like this) what is happening is the Sea Foam cleans out all the oil varnish buildup and carbon inside your engine. (This is a good thing) Sea foam is also super for cleaning dirty throttle bodies too! Carbon / varnish get all gunked up on the throttle body and can make your car run like crap. Rough idling, stalling etc. Purchase Sea Foam spray with the cleaning tube. Sea Foam will clean out your throttle body and make your car run new again. (Make sure your car is running when you do this)

Works very well I use it in all of my fuel tanks

Performs as should.
