Hello: Just a routine UOA for our 2011 BMW E90 328i, N51. 12/10/2014 sample = German Castrol 0W-30, 4147 miles on oil 04/10/2016 sample = Liqui-Moly Leichlauf 5W-40, 128 miles on oil 09/20/2019 sample = BMW TPT 5W-30, 4913 miles on oil Hengst oil and air filters. It is my belief the BMW TPT is Shell/Pennzoil GTL. Mostly warm to hot summer temperature highways miles. Easy duty for both engine and oil, but the motor seems to like the TPT oil. For an explanation of why I had only a 128 mile OCI for the Liqui-Moly oil, see my earlier thread. I reposted the original VOA and UOA results on 09/27/2019 (page 3). https:/
Just so it makes it easier to follow, let's talk about the BMW TPT oil here, and Liqui-Moly on the other thread.
