Hard to install as instructed.
Size: 32 oz
Nearly impossible to get it in the tire through the valve. Yes I removed the valve core.
Broke the bead on the tire and dumped it in. That worked great! So far no leaks.
They should definitely redesign the installation method.

Been using it for 15 years! Not sure where the Neg reviews come from?
Size: 16 oz
I've been using Liquitube since around 2010. I use it religiously in my ATVs and lawn tractor tires. Since I've been using this stuff, I've never had a flat before. I've pulled out nails and slivers of steel out of my ATV tires but yet none of them lose air or go flat.
I think some of the negative reviews come from improper use of the product or not enough of the product is being used in the tires. I think this come from variance in formula charts that Liquitube has had in the past on their bottles and on their website. The chart on their website wouldn't match the formula that was provided on the bottle. So I think alot of people get mixed up and not knowing the correct amount to add to each tire. Now Liquitube just puts pictures on the side of the bottle with an ounce measurement below each picture to tell people how to use it. But even that can be confusing. For instance, take the picture of the ATV that they show. Below the ATV it says 32oz. Now some people probably think the 32oz is for the entire ATV. Well that isn't the case. They want you to use 32oz Per Tire! Years ago Liquitube even used to say on the bottle to use 32oz per tire on an ATV. Now they just show a picture with an amount below it.
Now you'll come to find out that the 32oz they recommend doesn't match up to the formula they tell you to use to calculate how much each tire is supposed to get. So if you use the formula provided, you come to find that it calculates out to use less product per tire than what the bottle tells you to use. So that's very confusing as well.
So if you use it long enough, you'll be able to know how much each tire will need from experience. Just make sure there's enough on the inside of the tire to coat the entire inside as well as leaving a bit left over to circulate in the tire so it can be ready for a large puncture if that ever happens.
All in all, it's a good product that does what it claims. It lasts for as long as the tire does and it doesn't freeze up in the cold either! 5 stars!

The Ultimate Multi-Use Motor Treatment – A Must-Have for Any Vehicle!
Color: Pack of 4
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!

Engines run smoothly and efficiently
Color: Pack of 2
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.
