I've read on here that some companies (Honda, ect) use a special break-in oil (high content of moly) and that you shouldn't change it for a while. I just bought a new GMC Sierra 2500HD with the 6.0L and was wondering if GM uses a break-in oil? Also was planning on running Schaeffer 5W-30 with a Napa Gold Filter, does that sound good?
Thanks,
Jeff.
