And it only uses 1 quart max in about 11-12,000 miles. I use 15w40 in the warm months and 10w30 in the cold months. The truck runs only in the upper midwest all year long including the Dakotas, Minnesota, Wisconsin, Michigan, etc, but primarily Nebraska to Ohio, staying north of I-70.
Yeah, it may have a green tint, but it sure does the job. Mobil1, or really Delvac1 since we are talking about diesels here, wouldn't be any cheaper than the Schaeffer CK-4 syn blend I am using and I have yet to find any Mobil dealer that will ship product to my house free of charge like Schaeffer does. I cannot even get the Delvac Extreme syn blend in my area at a better value.

That sounds like a good enough reason to me for sticking with the product.
Roger that!
