just saw this on Exped. Portal. The poster has career experience with large truck's so it's possibly not a random internet "truth with no validity"
Exped. portal said:Just as an FYI for anyone with a C7 there is an upgrade to the HEUI system that includes another oil filter. May pay to check with Caterpillar regarding a retro fit. They don’t release something like this for a mothballed engine for no reason.
