What oil for my new engine

I disagree with most of what these posts say. Awhile back our wonderful government cut back on the amount of zinc that could be in oil due to that Al Gore thing. This includes Rotella which use to be great. Speciality oil used for racing (like VR-1) was excluded. Alot of guys run Brad Penn oil with great success and love it. I always ran VR-1 10/30 even on break-in. I would not consider syn. oil until it's completely broke in, say 20K. Syn. oil is so slick that it stops the break-in due to reduced friction. Wipeing a cam on break-in sucks. Of course all the concern over zinc is a non-issue if you build using a roller cam. There's alot of info out there if you google-up "ZDDP in motor oil".

That's my $.02 but as they say opinions are like assholes.....everyone has one.
