When I started running A's 45 years ago the debate was HD or plain 30 wt. I have been confused about the whole thing over the years but the info on this posting has cleared things up some, at least for a while until something new comes out. I have a rebuilt motor that I will be starting so my question is what to put in the fresh motor? I have read that you want a little friction during the break in period until the cylinder walls smooth out some.
