I don't need cleaning. None of my engines leak or burn or need top-ups between changes. I'm more concerned with HTHS and the demand older engines with looser clearances demand at start-up. Pennzoil Ultra Platinum seems to be designed around engines built tighter than Fort Knox. I'll use it up in a 2014 Pentastar but won't buy it again.I think it’s a good oil. I wouldn’t kick yourself. It’ll do fine. It won’t clean but should run clean.
