[oletrucks] Synthetic for break-in

[CLLLSLS@aol.com]

Hi everyone,

I've heard for the longest time that synthetic oil should not be used during 
an engine's initial break in, but I've just read that GM has been putting 
mobil 1 synthetic in Corvettes right off the asembly line since 1992! What's 
the deal here and what's the real nitty-gritty scientific reason for using 
natural over synthetic for break-in?
