  • SeaFoam SF-16 Motor Treatment 16 oz. Can (3)

Description

Sea Foam Motor Treatment is a 100 percent pure petroleum product that safely and effectively cleans internal fuel and oil system components, helping your gasoline or diesel engine run cleaner and more efficiently. Sea Foam is an EPA-registered product, and will not harm engine components, seals, gaskets, catalytic converters or oxygen sensors. Liquefies gum and varnish deposits or internal engine contaminants, removing carbon deposits, freeing sticky valve lifters and rings, improving idle quality, pinging and hesitation problems. By using Sea Foam to eliminate varnish and carbon buildup, mechanics can more accurately diagnose mechanical problems that may exist. That is why Sea Foam has been so popular with professional mechanics for over 65 years. As a fuel system additive, Sea Foam will clean carburetors, fuel injectors, clean carbon, gum and varnish deposits, adds lubricity to fuel, stabilize fuel for 2 years and control moisture. As an oil system additive, Sea Foam controls moisture, gum, varnish and residue deposits.

  • Engines run smoothly and efficiently
Style: 16 oz Size: 2 pack
I’ve been using Sea Foam SF-16 in both my outboard motor and sailboat, and it has proven to be an invaluable product for maintaining engine performance. This motor treatment is incredibly versatile and effective, making it a staple in my marine maintenance routine. One of the standout benefits of Sea Foam SF-16 is its ability to clean and lubricate the entire fuel system. It effectively removes harmful deposits and residues that can build up over time, ensuring that my engines run smoothly and efficiently. This is particularly important for marine engines, which can be prone to issues due to the harsh operating environment. I also appreciate how Sea Foam stabilizes fuel. This is crucial for my sailboat, which sometimes sits unused for extended periods. By adding Sea Foam to the fuel tank, I can be confident that the fuel remains fresh and free from moisture, preventing potential engine problems when I’m ready to hit the water again. Another great feature is its ease of use. Simply adding the recommended amount to the fuel tank is all it takes to start seeing the benefits. I’ve noticed a significant improvement in engine performance, with smoother idling and better throttle response. It also helps reduce emissions, which is a nice bonus for the environment. Overall, Sea Foam SF-16 is a fantastic product that I highly recommend to anyone with an outboard motor or sailboat. It keeps engines clean, running smoothly, and protected from the elements, making it a must-have for any boat owner. ... show more

  • Works Great
Style: 16 oz Size: 3 pack
Somebody told me about this product several years ago, and I used it on my four wheeler because the carburetor was gummed up. It cleaned the carburetor to almost new condition and it runs great now. I put it in my vehicles to clean the fuel systems. After use, expect to get better, gas mileage, and better performance. I don’t know why it works. It just does. It is a little pricey, but you get what you pay for. ... show more
