Sea Foam Question

[csogbk]

I picked up a bottle of Sea Foam at Wally World. It says auto and marine, gas and diesel. Is the right stuff? It's a 20oz metal "bottle" do I use a full half or should I use less on my 09 RSV? Thanks everyone!

[jemorrisonjr]

about one oz per gal of gas is what I use

What about marine outboard 2 stroke motors ? Does seafoam do them more harm than good ?? I have a little sputter in my 60hp Johnson, don't know if it's moisture or the carbs needing attention.

You could put Seafoam in an oil burning furnace and probably help it.

 

If it burns oil or gas, you can use Seafoam in it.

:sign yeah that:

We put the stuff in EVERYTHING! Cars, bikes, mower, weedeater, chainsaw, if it has a motor it will benefit from a little Sea Foam. Just pay attention to the directions and measure accordingly.

Thanks guys - I have a lawn boy 2 stroke also, guess I'll put some in that as well. I was concerned that the seafoam would 'clean' the cylinder and perhaps lead to a bigger problem.

when using it in a 2 stroke /aka 2 cycle engine, you want to be sure to put it in place of gasoline before you add your mix oil, or you will be screwing up your math on your mixture...ya know what i'm sayin?? don't want to thin out the mixture!!

 

yes i have used it for years in 2 cycle engines.

UH-OH - My Johnson outboard has it's own oil tank with a pump, so the oil and gas is not mixed until it reaches somewhere in the motor. The gas is a 12 gallon separate tank, so I guess I would just add seafoam as per recommended ratio ?

 

The lawn boy mower mixes, and I only mix 2 1/2 gallons at a time so a few drops is probably going to handle that. It's been hard starting lately so something is amiss, not the plug, I changed that.

[eusa1]

if you add it to the fuel, it doesnt matter about the ratio.... it's the products that you mix yourself, that are at risk... why?? because if you add the seafoam after you have the propper mixture, the seafoam will be just like adding more gas to the mix... thus dillutting the mixture

[Hummingbird]

understand what you are saying but I can't sort out the difference between putting 1/2 oz seafoam in 2 1/2 gals of gas and doing the same thing to 2 1/2 gals of gas and with 8 oz. of oil already in it.

 

It's STILL 1/2 oz of seafoam no matter when you put it in.

 

is it that the seafoam will 'cut' the oil after the oil is already in the gas and not cut it by putting it in before the oil ?

 

It'll be pretty difficult to mess up the outboard, it's got it's own gas tank.

 

This is getting waaaaay too complicated - probably should bite the bullet and go to a 4 stroke lawn mower, it's just that those old 2 strokes are really reliable - (sometimes )

[eusa1]

real easy... pretend the seafoam is gas.

 

put the seafoam in the fuel can, then fill the fuel to the whatever gallon mark, then treat that amount of fuel with the propper amount of oil.

[Hummingbird]

got it - the reason I was thinking about seafoam in the lawn boy was when I changed the plug I noticed a lot of black stuff on top of the piston - cuts down on the combustion chamber

( more compression ?) but also isn't right.

you will never damage that engine from too much oil in the mix, just foul a few plugs... your mix is too heavy with oil---thats still safest mix.. however if you thin out the oil too much, it will burn up the piston/rings

Thanks Mike - would you suggest just leaving the lawn boy as it is but check my oil ratio a little closer ?

[eusa1]

yup thats what i'm saying!
