I put a can in the boat tanks every fill up. Truck once in a while. Any engine (chainsaw, atv...) that doesn't want to run. Boat diesel heater too. Love the stuff.

Seafoam is good stuff. Also run my share of Marvel Mystery which apparently is solvent and spearmint oil.

The gentleman that owned my boat before me used Lucas Engine treatment. I tried it too and noticed that if I got fuel out of the overflow, it was green. I had to take the boat to a mechanic in Anch. and as he went through the check list, he felt he should call me. He asked: "Why is your fuel green?" I told him about the Lucas. I could envision him shaking his head even over the phone. I switched to Sea Foam. It took two years for the green to disappear. Best thing I ever did for the engine.

Another seafoam lover here too.

Read the can or go to their website and learn about its other uses

I'm a believer and use in everything from lawn mower, atv, boat, car or anything with a motor. Really helped smooth out the ATV.

I have been making my own for the past 2 years using diesel, naptha and iso-heet in a 4:2:1 ratio by volume. Cant tell the difference from the original.

Will try and post a link to a guy who tested different combinations of making seafoam and his results.

Do you mix a batch and store it till needed or just mix up what you plan on using? If you store it, in what type of container?

I read the "Make it Yourself" link. With my knowledge and grades in Chemistry class..... I'm going to buy it as long as prices allow.

Another use: It is hard to suck all the oil out of an I/O engine. My "certified" boat mechanic that I trust way more than any of the ex-wife's said: Just before getting back to port, like 3-5 minutes out, dump 6-oz. into the engine. I've done it twice so far and if I suck the oil out right after I get back to the dock it really comes out easily. I have also notice that my oil is cleaner during the year.

No idea what type of Lucas product Dave used (there are many), but the upper cylinder/injector cleaner additive is recommended by some very qualified mechanics and I run it in my Yukon a few times yearly. The only green fuel I have seen is old. A product called mechanic in a bottle has worked well on mowers and generators that have been sitting for a while and running rough- they literally run smoother within minutes. I found out about that product on the snowblower forums. Like any product, you can find praise and warnings for anything online depending what people are promoting. There are places that sell crappy gas and I spoke with a tanker driver who admitted to adding water to the fuel to
make more profit. I am sure it is rare, but it does happen. I like to buy fuel from the same stations recommended by Different Strokes who service my diesel, and I put Stabil 360 and Red Heat (antifreeze and water remover) in anything I may not be running in the next month.

Love the stuff, I put 1 can in every time I fill up my boat tank. It keeps everything clean. For my truck and tractor I use Marvels Miracle Oil, but they’re both Diesel engines.

I mix it up a batch at a time and keep it around till i use it. I store it in old growler bottles since they are glass and tinted to help keep the light out.

What about all the guys who never run any magical mystery additives and have clean, perfectly running engines? Are they all just lucky?

I'm mixed it in with my mix oil for my chainsaw and power ice auger.
Put about an ounce of seafoam per gallon of gas.
I'll store it all winter in just a one gallon gas can.
I just put some colored electrical tape on it the handle so I know which can has the mixed gas in it.

I believe much depends on use and climate. It has rained so much over the past two months in Valdez that everything has moisture on it and is sweating. Most of my tools are wet just sitting in the work shed. I open up my boats engine cover and it is just sweating moisture. My chainsaw gets tied down on the back of the sled, 2-3 miles across the river, used, hauled back and forth about 4-5 times a day when I'm cutting. Some years I've cut 8-9 cords. There is just no end to the moisture over here. Lowe River is lapping at the highway again. Creek behind the house is the highest I have ever seen since the 100-year flood back in 06(?)

I listen to my boat mechanic as he deals with issues way more than I do. Like tank full/tank empty in the winter for the boat. He says that over 3 months that the gas loses octane. So, leave them empty. But we get so much moisture over here, I opt for full with Stabil. I run half a tank empty in the spring and fill it with fresh. Then switch and repeat. I won't run a tank empty until I'm sure I have fresh tank in the other one.

Many claim that they get water in their gas at the fuel dock here. I have poured out and inspected my fuel filters for the past several years and I can say that that is false. I might have a tiny bit, but nothing worth mentioning. Even when you have to fuel up in the rain, nothing in the fuel. BUT, does the Seafoam help that. Can't say for sure.

Agreed. Living in condensing atmosphere is fun times. But I typically don't run any kind of additive and I've never received any water from the harbor fuel dock.

You should try a bottle of seafood and see if it makes a difference in any your high milage, "perfectly running engines", then report back to us

Living life the right way?

I don't use seafoam regularly, but I will use it with an engine that isn't running smoothly. Sometimes it works and sometimes it doesn't. To me it's worth the 8 or 9 bucks find out.

I don’t think it’s as simple as that, for one thing I think the octane level in the fuel you use has something to do with it among other things. I use 90 in my boat in conjunction with with sea foam. I mostly use it just to clean out the injectors. I am lucky if I put 100 hours a summer on my motor. Is it necessary probably not but I can tell you when I change the oil and plugs every fall, there is little build up and the oil isn’t as dirty as it was before I tried. As for using Marvels I heard it lubricates the valves and stuff since they came out with that cleaner burning diesel fuel. Again no way of knowing for sure but I would rather not find out by having to rebuild my top ends on my truck or tractor.

Seafoam is amazing stuff.
Years and years ago my little sister had a car that she abused the heck out of.
Well it developed a serious and obvious knocking problem.
So one of my dad's co-workers suggested he try seafoam in it.
Dad took off the oil fill and by the time half the can of seafoam was in it the engine had quit knocking.
I like to use it a little bit in my small engines as it really seems to help keep the carburetors clean and keep them running well.
Normally in my daily driver I don't add seafoam unless I'm having engine issues.
But I can say it is very good stuff!
