Best oil??

I know there is a huge post on here somewhere on this subject, but of course now cannot find it now that I need to buy some.

If someone could post the link, or let me know what people use that would be great.

I remember reading the the best oil has zinc in in for our old engines, and there were many different types, but which ones are actually "good", a some of them just seem to have better marketing than actual product.

I just broke in my fresh engine with basic oil, now that it is broke in I'd like to change it with the oil that it should be running.

Thanks a lot!!!
