Make sure you shake the gas can well after adding the oil. I always filled my 5gal gas can first and then added the oil, some added the oil first and then the gas but I found it stayed on the bottom too much.........Irv

Thanks you guys for all your help I really do appreciate it.
So TCW III oil for the mix?
Am I looking for a specific brand, I don't know exactly what TCW III oil is...
Sorry I am such a rookie, I just don't want to make any mistakes!
Can I get this at Fleet Farm?

And while I am at Fleet Farm should I get a 5 gallon gas container?
Then at the gas station should I fill the 5 gallon container with gas, add the 28 oz. of oil shake it up a little and then add 5 more gallons from the gas pump into the boat? Because I have a place to just put the nozzle of gas pump right into the boat?

Thanks again I really appreciate it!
Have a great weekend on the water
