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

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)

Great product. Satisfied Customer.

Been using this for years, especially on my motorcycle, keeps fuel system clean. No fuel issues for start ups. Seems to give better performance. Highly recommended and this is a great price

Excellent product! Helps with gas mileage too.

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

Use in all my vehicles and small engines. Make a rough engine smooth!

Worked fine

This is an amazing additive for keeping varnish from forming in small engines. I use in fuel for lawn mowers, gasoline power tools, and generators. It will eliminate the hard-starting of small engines after use.
