I'm a little confused on what oil mixture to use after break in. Forum member deacon and a few other places have suggested a 32:1 but most places I see, say a ratio of 16:1. A lot of things people do are just out of preference, but those are two opposites ends of the spectrum. Which one is correct? I'm using 20:1 right now, but once I get my engine broken in I'll need to switch.
