I like the oil used on the 1/2024 run mo better. Nice report.
Same oil. It’s been PP 5-20 since I drained the factory fill at 2500 miles.
I did notice it looked like this round showed less additives past sodium.
Assume the lower cooper is just the oil cooler continuing to shed less metal as it ages. Iron seems about the same across the board and in line with universal averages (those I believe are based on a 5k interval) so I’d be a bit lower if I changed at 5k vs 7500.
