Hi everyone, this is my first UOA so any helpful advice is appreciated.
The car in question is an X5 M50d with the N57D30S1 tri-turbo engine that has been ingesting diesel since the last oil change. That's getting fixed as soon as the timing tools arrive. It's the presence of diesel in the oil that prompted me to get a UOA done as I was concerned about elevated bearing wear due to the diluted oil (which was already quite thin to begin with...), but the copper & aluminium levels look OK. The iron levels are concerning me though.
Oil is Fuchs Titan GT1 Flex23 LL04. Oil change interval history is below, see if you can spot where someone who cares about maintenance (i.e. me) bought the car:
24,046
34,108
49,015(!!)
10,833
9,428
11,442
11,564
In the latest oil change, I've switched to to Penrite Enviro+5W40 LL04.
Cheers
