This was my first OCI with this vehicle, I ran the GC 0-40 and it seemed to have worked well through a PA winter. My real concern was "what was in there from the past", that is the main reason I pulled it @ 4500mi. A good bit rural-driving, some hi-way with MANY warm up sessions (idle). The 4.0 probably used less than a 1/4 of a qt during this OCI. My guess is that this was the first time it has seen synthetic oil. Whats up with the titanium ? I think Castrol uses it in there USA stuff, but not GC...maybe I am wrong. I would think there would be other indicators if it was valves or bearings..... But I'm no expert.
