Used this for the first time in two very old and well used small engine carburetors with outstanding results. The first one was a 23 year-old John Deere lawn tractor that always was hard to start after sitting for a few days. I thought for sure I either needed to rebuild the carburetor or replace it, but decided to try this instead. I followed a pretty simple how to video I found online, poured this stuff straight into the carburetor through the air intake, and now it starts on the first tap of the starter every time. I don’t want to say this stuff is magic but it saved me a lot of work. The second was a 35 year old push Toro lawnmower with the original carburetor. Although it was running pretty good before hand, you can clearly hear a difference after using sea foam now it starts smoothly on the first pull and runs better than most new machines. I highly recommend sea foam for anyone who’s having similar issues or just wants to maintain their equipment. I’m now adding it to every gallon of fuel that I use in my lawn equipment.

The Sea Foam SF-16 Motor Treatment is an outstanding product that truly delivers on its promises. After using it in multiple applications for my vehicles, I’m convinced this is a must-have for anyone looking to maintain and enhance engine performance. The 4-pack is an excellent value and ensures I always have some on hand for routine maintenance. Why Sea Foam Stands Out Multi-Use Versatility: This product is a game-changer! I’ve used it as a fuel additive, an oil treatment, and even to clean out stubborn deposits in my carburetor. It works flawlessly across applications, making it an all-in-one solution for keeping engines running smoothly. Improved Performance: After adding Sea Foam to my fuel tank, I noticed a significant improvement in my vehicle’s fuel efficiency and a smoother idle. It’s particularly effective at removing deposits and buildup that can reduce performance over time. Easy to Use: The instructions are straightforward, whether you’re using it for fuel, oil, or cleaning purposes. The precise measuring cap ensures no mess or guesswork, making it simple to get the correct dosage every time. Great for Long-Term Maintenance: Regular use of Sea Foam has made a noticeable difference in prolonging the life of my engine. I’ve also used it to revive an older lawnmower engine, which now runs like new! This product pays for itself by preventing costly repairs. Packaging and Value The 4-pack is perfect for multi-vehicle households or anyone maintaining more than just a car. I’ve used it in my truck, car, and small engines like my generator and lawn equipment, and I still have plenty left. Pro Tips Add Sea Foam to your fuel before a long drive to maximize its cleaning effect. Use it regularly in oil changes to keep sludge buildup at bay. It’s also great for seasonal storage—just add it to your gas tank to stabilize fuel and protect the engine. Final Thoughts Sea Foam SF-16 is the real deal for anyone who values vehicle performance and longevity. Its multi-use functionality, ease of application, and proven results make it a standout product. I’ve already seen noticeable improvements in my vehicles and equipment, and I’ll continue to use it as a staple in my maintenance routine. Highly recommend it to anyone who takes pride in keeping their engines in top shape! Pro Tip: Whether you’re a DIY mechanic or just looking for a reliable maintenance product, Sea Foam is a must-have. It’s one of the simplest and most effective ways to protect your investment and extend the life of your engine. Don’t hesitate—this 4-pack is worth every penny!
