Well this little 4 hp evinrude seems to be running good now. But i recall when i fuel up the tank it said that it was a 3 gallon tank, not true it was all i could do to squeez in 2.5 gallon. so i think i might of been off on my mix along way. because i added 8 oz. of super tech tcw3. so my question is this if i put in 2 exact gallons of fuel how many ounces of tcw3 oil should i be adding for a 50 to 1 mix ratio.? thx Joe
