How much seafoam?

[M1Tanker]

I see that a lot of folks use seafoam as a stabilizer rather than stabill.

How much do you use per 1 gallon of gas?

The can says 1 oz. per gallon as a maintenance additive but I am sure most folks using it on this board have enough experience/experimentation to know how much to use.

I put in an ounce per gallon.

If you use Jiffy oil you don't need to add a stabilizer because it already has it. That's basically the difference between Jiffy and Strikemaster oils. I use it year around, it works great in my chainsaw in the summer.

When mixing a gallon of gas, I use "not quite" and ounce. Just enough to try to keep condensation out of the gas can. Auger gas can sit for so long fluctuating between fridged to "warm" conditions condensation can be a problem.

One ounce per gallon is all that is needed

I switched to the New Marine Blue StaBil formula last season. It has 5 times the carb cleaners and protects the engine from ethanol fuel cylinder problems of moisture contamination or rusting internally.

I use 1.5 to 2 oz Marine Blue StaBil per gallon with the recommended oil/gas ratio.

I also run a dose in my vehicles, really seen a difference in the fuel injection system, she has more response and idles and starts much better in cold weather.
