Adding Sea Foam to 2-stroke pre-mix fuel [SOLVED]

Hi Sea Foam

For a pre-mix 2-stroke engine, is it best to add Sea Foam after you mix your gas to oil ratio? I also noticed that the instructions show to add 1 once to every gallon for maintenance, but also shows to add 2 ounces of Sea Foam for pre-mix 2-stroke engines.  Why is the ratio more for 2-strokes?

Hey Lance. You can add Sea Foam to fuel before or after the 2-stroke oil has been mixed. We also recommend two ounces per gallon for pre-mix 2-stroke fuel to help with minimizing oil residues that form in carburetors and chamber areas.

How often should I use Sea Foam Motor Treatment in my 2 cycle engine?

What if I have already added a fuel stabilizer to my 18 gallon tank of oil and gas?

Can you add too much? There is already some gas in the tank, but I’m not sure how much. I’m about to add 5 more gallons of gas.
