Re: ? difference btwn 2strk marine oil tcw-3
Two stroke oil for air cooled engines is formulated differently. It is for air cooled engines that run at various rpm. Marine oil is for liquid cooled more-or-less constant speed engines.
I wouldn't mix them, and I would only add MMO to the mix AFTER you mix your gas and oil to 32:1, not as part of the mix.
Now I can almost guarantee you will get at least 5 differing opinions and debates about this.
They make two different oils for the differing applications for a reason.
