So I had put PYB 5W-20 in my Pentastar equipped Pacifica at about 3k miles. Was noisy right from the get go and I wasn't too happy with it. Put 2k miles on the PYB and drained it out today. Filled with 6 quarts QSUD in the 5w-30 flavor and boy it is whisper quiet now. I run the Fram Ultra in both my Pentastar engines, seems like the best bang for the buck for this engine.
The Pacifica calls out 0w-20 for whatever reason but it will never see that as long as I own it. So far very pleased with the QSUD. I'll report some long term results as I put on miles.
How is the QSUD working out for you? That is what I have just purchased and plan to use in the future.
