BMW X5 4.4L Changed oil out at 3K and also at 7K with Redline 5W30. Car is a bit past 12K (5000 miles) and I'm planning to do a oil change this week. I'm planning a UOA on this oil and the next. On this oil change, I will once again use Redline 5W30. Should I try this with LC or not ? On my next OCI, (late November), I will be change it out with GC 0W30. I'm planning a UOA of the Redline with TBN and then I'm going to follow the same steps as above with the GC. Any benefits with LC in the oil ?
