Here is a UOA from my 2009 BMW 328i (E90) with the N51 engine and 5,000 miles on Valvoline Euro 5w40. Car had 90k miles at the time of the sample. Interesting about their note on the fuel, since this car now sees mostly short trips. My commute to work is about 6 miles, where the previous samples were done while I was commuting 100+ miles daily.
