The legends are true! SeaFoam is great for preventing gunk and degunking engines.

Reviewed in the United States on January 28, 2021

Size: 1 Pack (16 Ounce)Verified Purchase

Decades ago, I had heard the lore of SeaFoam for engines from an old car guy. Its virtues were described as being part carbeurator cleaner, part fuel stabilizer, part gunk remover. Over the years I have used this in all manner of engines, but it has been my go to for years now for small engines. It keeps my snow blower, lawn mower and pressure washer engines clean and extends the time between tuneups. I will usually start and end the season with a mixture of straight gas and SeaFoam as directed and then I will run the engines. SeaFoam will produce that satisfying puff of white smoke as it burns and in turn it lessens the residue in the small engines and helps them run better. I have noticed less gunking in my carbeurators (especially the little bowl ones with the pinhole sprayer) and the engines run smoother without hiccups.
Seafoam’s formula is nothing space age, it is just a marine gasoline cleansing mixture that also helps keep small engines running smooth and hopefully prolongs their life. The price is very reasonable as I get maybe five or ten treatments out of a can, depending on the size of the engine. I would recommend it for seasonal maintainence and even as an option for a nonstarting or rough running small engine. Good luck.

Mechanic Recommends Sea Foam -- Best Gas Treatment for All Engines

Reviewed in the United States on August 19, 2015

Size: 1 Pack (16 Ounce)Verified Purchase

We have a small-engine mechanic who turned us onto SeaFoam motor treatment -- and against most gasoline preservatives and treatments. He said he'd drained, or seen inside, thousands of gasoline tanks, and the stuff sold as gasoline storage additives was often still there, sitting as gel on the bottom of the tank. Just gunk. He also said most brands of engine treatment weren't worth the money. However, he swore by SeaFoam, which I'd never tried at the time, and my experience since has proved him out. I've had many rough-running engines find their power and performance again, with nothing different, but a shot of SeaFoam in the gas tank (and the crankcase).

We own a number of vehicles and equipment with small engines, from a compact backhoe, to a ride'em Husqvarna mower, weedwacker, chainsaw -- and on the larger size, a Honda SUV and Ford F150 pickup. All of them have benefited greatly from the regular use of SeaFoam. However, when we're running the road vehicles a lot, especially in the summer, we go through gas and don't necessarily add SeaFoam with every fill. Recently, the Ford began to run rough. It stalled as I pulled up to corners and lights. In the past, that would have meant a mechanic and an expensive tune-up. All I did was go for a fill-up, and started by adding a full can of SeaFoam. Problem solved, just like that.

The Terramite (made in the USA) backhoe is not used a lot -- and as with most motors, that is a problem. It's bad for an engine not to run it -- and especially, in most cases, for it to sit with gas in the tank. The backhoe has a Kohler Command 25-horse gasoline engine that powers the hydraulics that run the wheels, steering, front-loader, and backhoe. I change the spark plugs each season, but it, like my Stihl chainsaw, and 6500 watt backup (gasoline) generator, and for that matter, all the small engines, can be hard to start after a hiatus. And even when they get going, they'll run rough. I used to drain the tanks frequently, then run them dry, then fill again before use, and hope for the best. But SeaFoam has changed all that. Throughout the summer, I can leave treated gas in the tank, and have little problems with starts or rough running.

In the smaller equipment, I dose the gasoline with each fill (1 oz per gallon), as SeaFoam cleans both carburetors and full injection systems. It is good for gasoline and diesel engines. Added to your crankcase (1.5 oz per quart of oil), it cleans deposits and quiets noisy lifters.

These days, most gasoline is mixed with ethanol and that's a bad thing for small engines. Ethanol goes hand in hand with water -- and as we all know, water in the gas is anathema to motors. Again, my small engine mechanic told me, 90% of the no-start problems he had to deal with were caused by ethanol-caused water in the fuel system. SeaFoam actually controls moisture and prevents this problem. It also de-ices and is anti-gel.

In my opinion, when it comes to gasoline and diesel engines, large and small, SeaFoam is THE Silver Bullet. My equipment is often running, while my neighbors are running with theirs to the shop. I've told many about SeaFoam, but some people seem to want to do it the hard way.

By the way, I also swear by PRI-G fuel additive for long-term gasoline storage. I keep 100 gallons of gas in tanks for emergency use. We are in a rural, wilderness area. I was introduced to that by survival expert, Steve Harris. He said he's had gasoline that was 10 years old still run equipment, because he'd added PRI-G to it (you can buy here on Amazon). Of course, you have to remember to add more PRI-G each year -- that's the catch.

So our rule of thumb is, PRI-G for long term fuel storage -- and SeaFoam for month to month. Also -- this price is right! Of course, when you compare the cost of equipment breakdown, and having to take anything to a mechanic, this is almost free. However, apples to apples, this price is cheaper than Walmart -- and up to $4 cheaper per can than many auto supply and hardware stores.

Can't say enough good things about this product! Highly recommended.

! I took my used Audi TT with 68,000 miles on it to my race shop in West Palm Beach. I wasn't sure if I could trust this product but these guys said buy more of it and keep using it it's an excellent product!

Orbit racing is probably the best race shop and all of sudden Florida. Gunner racing is also an excellent shop and they did a restoration on my 73 RS Carrera lightweight which I actually sold to Jerry Seinfeld.

The guys at orbit racing recommended that I continue using this product and they even told me I can put it in the oil tank!

I'm a very happy customer!

I use it in all my small engines

Reviewed in the United States on January 4, 2020

Size: 1 Pack (16 Ounce)Verified Purchase

I have a tiller, 2 push mowers, garden tractor, edger, 2 generators and a pressure washer that have their own engine. I don't use some of them very often so they can get gummed up from lack of use. I run some SeaFoam in the gas, certainly has helped me numerous times with poor running performance. You'll read reviews where they say it didn't do anything, etc, etc. You need to remember this is going to slowly clean the fuel system, it's not an instant thing. As the engine is running some of this is running through the fuel lone, fuel pump if equipped, carb/injectors and combustion chamber. As it's flowing through it's removing 'gunk' that has built up. For instance my garden tractor was surging pretty bad last spring from setting a bit over the winter. I put some seafoam in the gas tank and mowed the yard (several hours as my yard is big). By the time I finished the engine was running perfectly. Same thing for any engine you put it in. You'll need to run a tank of fuel with seafoam to begin to see any change. If you have a problem other than a fuel restriction this isn't going to fix it. Some people also put this in their oil. I never have and don't plan on it so I can't speak to any performance there. But if you need your fuel system cleaned up, this will do it. Just remember it takes a while for this to work while the engine is running. For really bad conditions I've added more than specified without any problems. Might even run it in a couple tanks to get the fuel flowing as it should be. Just remember it takes a little time to do it's job. Note: I have no affiliation with the company, just a satisfied used of the product.
