I have just bought a 1989 Merc 45hp (Classic 50). I don't know much about mercs except that they used to say to only use Merc 2 cycle oil. I assume that the previous owner was using regular merc 2-cycle oil.
I've used synthetic 2 cycle oil in some of my other equipment and it burns clean and the engines seem to last longer. Can I use synthetic in this Merc?
