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?
The GM Engineers design the car but the lawyers wrote the break-in instructions.

Drive it hard! As a mechanical engineer who slept in a Holiday Inn Express I will trust the race car engine mechanics.
