Hello Vanagon lovers!

I just bought a rebuilt engine for my van.The person , who works at a
local VW dealer as a tech,rebuilt it 2 years ago and it has zero miles
on it.Since I'm on a low budget, this was my only option ....and the
price was right!Would it be smart to use mobil 1 oil at this time or use
a regular type oil for break in purposes? Maybe a little marvel mystery
oil down the spark plug holes at start up?Let me now your thoughts and
feedback.
Thanks!!!
Kevin
