This is a sample pulled from my Durango 3.6L with 117,000 miles total and 5,000 miles on the oil. The oil is HP 5w-20 by High Performance Lubricants in Manteno, IL. This oil is intended for extended drain intervals. It's not inexpensive, but it's clear that it holds up very well. I will sample again at 10,000 miles. Filter is a Fram Ultra, which was not changed at this sample. Consumption was zero, which improved from about 0.25qt every 5,000 miles.
