It's futile to try and convince people that have not experienced Seafoams graces.........especially if they don't understand a bit of chemistry........simply put today's fuels turn to varnish in short order and Seafoam dissolves that varnish........

You can take a fuel system apart and scrape, flush and clean out all of the varnish at $150.00 per hour or.......you can, over a few days or weeks use a product that will do it for you............either method arrives at the same conclusion........

If you're wondering... seafoam is

1. Mineral Oil 40-60%
2. Naptha 25-35%
3. Isopropyl alcohol 10-20%

Ahhhh yes... Ive been handed the swift justice of a seafoam "shock" and fuel system cleaning on my 97 Vista 278.

Fair warning: If your fuel system is very varnished and/or pretty contaminated, be prepared for potential problems.

My case might be unique, or not... but either way I bought my 1997 Vista 278 with 90 hours early spring 2012. Read: very very little usage over 15 years, and fuel sitting in the tank/lines/engine/generator for months/years perhaps with little or no use.

I was having no problems that I could remember and used sea-foam as a preventative. Ive used it for years in my yard equipment, cars, etc. Well, it loosened up all kinds of crap in my fuel system. It did its job, absolutely. Filled up my generator carb bowl with crud, I am also pretty confident the crap is what I picked out of my low pressure fuel pumps when they both sh*t the bed.

Worked for me!!! LOL Wish I had known I had such a dirty fuel system BEFORE I ran the sea foam... ended up costing me 2 new low pressure fuel pumps, a generator fuel pump, and countless fuel filters/water separators. Now I'd run it without worry but I learned my lesson... I didnt know my fuel system was that dirty.

Snake oil, like many other brands of additives.
If this technology was that proven, don't you think oil manufacturer's would mix this in to their blends?
Additives and their effectiveness on engines is almost impossible to gauge, which is where clever Marketing takes over!

The potency of in-tank injection cleaners is too weak to remove most contaminants.
If it was a harsh enough solvent to actually do anything, the crud removed will block the tiny orifices in your injectors.
If you feel all proud by playing backyard mechanic, all the power to you.
p.s. Most Mechanical workshops buy these types of products as an up-sell technique.

No seafoam (naptha) is documented to clean up gasoline varnish. Not one can in 50 gallons though. More like one can in 5 gallons. Sitting for a few weeks.

LOL, sorry friend but at what point did you think a 1997 boat with 90 hours wouldn't have a fuel system that was ruined? Low hours on old boats = more problems than high hours on old boats.

I cant say it was varnish... I dont know what it was. I do know I had to clean the carb bowl of my genset 3 times though. Also right after the seafoam treat, I changed the fuel filters which I had just installed and emptied a bunch of weird crap (looked like sediment).

And of course the risks of having a boat with low hours was a big consideration... I figured heck, Ill run some seafoam through a tank at the "shock" level ... what harm could it do? Well, it definitely cleaned out the system...lol.

I'm not complaining - I mean, it was an unexpected series of events that occurred after the seafoam; I still use seafoam in my outboards, cars, atv's and lawn equipment. But methinks I will hold off using it on a boat that *might* have a dirty fuel system in the future without considering the potential consequences of its cleaning ability.

Wow, this is all new to me. (seafoam)

I had heard of Seafoam being used as part of the Winterization process, and assumed it was some kind of engine fogger. How does one use it for winterization?

Some feel it's a suitable alternative to Sta-bil. Personally I don't think it is and wouldn't (and haven't) used it for winterization.

It's not available in the UK , but neither is Budweiser. Hang on a minute, Budweiser is available here, someone must buy it, it's the really very good American beers that aren't available here !

You guys have the Budweiser equivalent: Stella. You'll laugh knowing that here in the USA it's considered a "Premium" beer and quite expensive. My favorite is Guinness, Smithwicks, and Chimay so in all reality I'm just drinking what you guys drink. Although right now I'm drinking a Pabst Blue Ribbon, you can get a 4 pack of 16oz cans for $3. Actually good flavor too, better than Budweiser.

Ric,

Are you referring to Stella Artois or the Egyptioan Stella ? Re the latter, when we had a Nile cruise vacation there some 25 years ago there were 2 types; "Stella Export", a consistent, strange smoky tasting light brown beer and the very much cheaper "Stella Local", which varied a huge amount; from a very pale Bud type colour to a brown colour like Smethwicks, with varying degree of cloudiness ! Avoid , it was cheap for a reason ( Egyptian public toilets near Luxor are not recommended, even in emergencies, believe me !)

Stella Artois is a strange one here; the original was 5.2%, dropped to 5.0% for the UK market (brewed here), than to 4.8%. Nowhere as nice as it used to be, always on special offer in the Supermarkets, it's lost it's original upmarket reputation.

I liked the Samual Adams ales when I was last in Florida, I know they are not local but who cares !.

+1 on sea-Foam. I have used it on a lot of equipment. I swear by it. On big stuff we put it in a separate small tank (guaranteeing a good mix) and run it.

Most recently we used it on a 1990 four Winns 2.3L that sat untreated for 5+ years. We used a separate fuel tank again, plus we poured it straight in the carb through top vent and let it sit for a few days. We did end up disassembling the carb later for other reasons and it was honestly clean as though it never had an issue in the first place.
