I break in with regular 10-30 oil and then switch over to Mobil I 10-30.
It is up to the individual as far as using 10-30 or some other weight
and brand, I have found the 15-50 good when running hard on drag strip
but for just every day driving with the occasional punch I personally
stick with the 10-30, in my 330hp and 500hp cars. I buy the Mobil I
cause that is what Sam's carries and I buy my shop oil there. Again,
that is just what I do.

I'd like to hear your thoughts on breaking in your freshly rebuilt engine using
synthetic oil...
Also, if you use synthetic oil in your daily driver or Chevelle, what brand and
viscosity do you use?
Thanks,
