Who would you trust?
Sorry, but GM's break in instructions have never failed me in 40 years, I am not going to go against them now...
Anyone that says GM Engineers don't know what they are talking about, remember who designed the Camaro? I think it was GM Engineers...You bought the car designed by a bunch of engineers you don't trust, so who here is the dummy?

With you all the way, im an automotive engineer myself and GM break-in instructions are 100% correct.
Darin and the rest of the C5 crew have their opinions and trials, which im not saying its incorrect but notice that engine oil intervals are changed earlier and more frequently than the GM Manual instructions. This is their own way in maintaining their engines.
Be safe, go GM manual.
