One type is not "better" than the other, but there is a difference in air cooled and water cooled 2 stroke oil. Air cooled motors typically run at higher temps than water cooled ones, so the additives are different. For long engine life don't mix and match, just get what's needed for each type. For ten bucks he can get a gallon of TCW3 oil at Wal-Mart and since the mid 60's it's been 50 to 1 for most outboards.
I didn't mean this to say anything about synthetics, it was to the statement that air cooled 2 stroke oils are better than water cooled ones. They're different so that they don't leave deposits at the different operating temps, there are good oils in both categories.
