Is it ok to run seafoam with everytank or is it just used for cleaning once in awhile? Also I use marine sta-bil in every tank, should I use seafoam as well to keep it clean or is the sta-bil enough?

Re: Seafoam

What kind of gas are you running that you need an additive in every tank to clean your fuel system?

Re: Seafoam

if your fuel system is that dirty you need to repair it properly and not depend on some additive to do a partial job at best at it.

Re: Seafoam

the fuel sys aint dirty, I run the stabil to help with ethanol stuff, it was recomended by my mechanic as added protection.

Re: Seafoam

Just make sure you leave enough room in the tank for actual gasoline.

Re: Seafoam

reddog--you have a legitimate question---I run Seafoam 1st & last tank of the year and Stabil every tank---
Seafoam is kinda expensive for every tank-but if you suspect water in your gas you need to try & figure it out--
maybe install a inline fuel / water separator.

The ethanol stuff doesn't need any help, it is one of the best fuel system cleaners available.

Re: Seafoam

Seafoam is great stuff, I use it to fog my engines in the fall. Works well for un-gumming old dirty carbs run in the fuel, but I don't think I'd use it with every tank. Wont hurt anything, but thats money better spent on beer.

Re: Seafoam

None of it needs to be used in every tank, and Stabil is not going to help a great deal, or do much at all if the boat is used with any frequency. You are wasting money, but it may you feel better.

Re: Seafoam

I live and boat in a hot and humid area, I keep Stabil in my tank all of the time, I use Seafoam a couple times a year, I always keep my tank full of gas. I am not sure any of it is necessary at all, my old boat sat for 2 years one time with a full tank of Ethanol gas, when I got so I could use it again, I changed the fluids, tuned it up, started it up on the trailer, ran about 30 min on the muffs, put it in the water and ran it near the dock and all was well. Trailer boaters have been using Ethanol gas for many years it they pulled into the average gas station and filled up. I use the treatments to make me feel better, they can't hurt anything.

Re: Seafoam

while it's true that treatment/additives are seldom needed IF the entire tank of gas turns over every 30-45 days, I believe stabil/startron is still beneficial in hot humid areas where the boat is left in the sun--it's breathing in a lot of moisture daily. At a dollar an ounce it's pretty cheap protection, compared to the cost of the gasoline. I also use Yamaha ring-free year round; haven't used sea foam and don't know that I would use it regularly.

the advice concerning ethanol and fuel treatment has to always be taken in context of the conditions of the location where the advice comes from. What works in dry, cold areas doesn't in hot humid areas.

Neither stabil/startron will prevent phase seperation from occuring once the conditions of phase seperation are met so what's the point?

Exactly. The real issue is phase separation, Stabil can do nothing to help that, Startron makes some claims, but doesn't go as far saying it will stop it. Although I think they say it will rejuvenate old stale fuel, which if you think about it doesn't actually seem possible.

Re: Seafoam

how about the stabil for ethanol treatment??

it is different than just stabil (which I understand is for longer term gasoline storage)

will the constant use of the blue MARINE ETHANOL STABIL , help in an outboard that is used weekly???

I had heard it helped prevent hose and gasline damage, as well as carb gasket damage

Re: Seafoam

It can do very little other than help keep the fuel fresher, same as the normal stuff, the label says it doubles the amount of some ingredients, none of which really do much.

The one thing in common to all of the miracle ethanol treatments is their hope that you live in fear of E10 and continue to spend money based on that fear.

The one treatment that works to help prevent phase separation due to ethanol, is more ethanol. With more ethanol in the fuel more water can be absorbed before it separates.
