This is from my L96 GMC 3500 CC, 4wD. This truck is used under heavy service, a bunch of towing 12000 lbs over varying terrain. A few things of note........
Red column is AMS Signature Series 5w30. This 5500 mile run included two RV trips to NC mountains and NC beach. Various high way and city driving, I suppose average cruising RPM was 3000, loaded. Not sure of the actual full loaded miles
Blue and Yellow column are AMS OE, and Napa Syn, 5w30. Both with various city and highway, towing my 12-13k gooseneck with my excavator, along with unloaded trips also. Not sure of the actual full loaded miles.
OCI for the Napa syn was 5-5.5k, just forgot to write it on the test sheet when i sent it off.
If there are any questions or comments, let me know
