Worked For Me..

It Works.. I like to add an ounce per every qt of oil to the crankcase every oil change.. Usually pour what's left over in the tank. Then use the spray as directed on the can to soak the engine. I've even heard of ppl removing the upstream fuel/air O2 sensor and soaking the catalytic convertor to clean that as well. Read full review...

I Don't See a Difference in using SeaFoam

I really can't say that I can tell a difference when using this SeaFoam Motor Treatment. I've put it in my car, van, lawnmower and motorcycle and except for the lawnmower letting out the white smoke from the SeaFoam, I don't see a difference in using this product. I guess overall I would not recommend this product. I'm not a mechanic but from my point of view, it does nothing. Read full review...

Great Product

I was told of the superior fuel stabilizing provided by using Sea Foam by a small engine technician. She told there was none better on the market and she had tried them all over 20 years in her trade. She mentioned it was great for fuel injector cleaning and also as a crankcase additive. I know for me it has never caused any gumming-up or fuel problems that some StaBil products caused. And it worked great at eliminating rough idle in my '08 Toyota Camry and '97 GMC 350 V8. I also use it in my boat motor fuel to keep it running smoothly and to stabilize my Mercury's fuel through the winter..
Highly recommended.Read full review...

Im sold

I never believed that something in a can , can improve a vehicles engine performance. But this product did. I put it in the crankcase of my 4.7litre Toyota V8 with 270,000 miles on it. Took away all the engine noises. And I've added to gas several times and my engine is running so good now , after running and sounding like it was time to retire vehicle. Now I'm going to keep it for another 200,000 miles because of how excellent sea foam has made it sound and run, no bull. Stuff really works. Read full review...

Belief comes with Use

You must try this before pulling heads for valve work or leaking rings... I have saved myself and others many headaches with this product.

Awesome product

I added 2 cans of this to my gas tank since my vehicle has a carburettor and holds 22 gallons of gas. I took it out on a 70 mile run and noticed a change after about 20 miles. I drive a 1972 Ford Galaxie 500 with 265K actual miles. This is a product that I will use again.Read full review...

Amazing

I'd never heard of Sea foam until a friend suggested it to clean out the weed eater. Now I'll be using it on all my engines.
