This is the same oil as my previous 5100 mile UOA with another 2600 miles of mostly highway miles. Houston-Indianapolis Saturday 06/06 and Indianapolis - Houston 06/13 about 1050 miles each day. Cruise control set to about 5 over speed limit with an occasional jump to 80-90mph passing. Oil temps about 100-110 over outside air temp. (62-97F)
I pulled about 1/2 a quart for the 5100 mile UOA - replaced it with Red Line 5w-40 (old formula). The oil was changed this time with fresh 5w-40 from Red Line (from Racer Parts Wholesale in Indianapolis).
The copper was only 4 ppm after almost 50% (2600+) more miles compared to the original 5100 mile UOA.

Blackstone comments - no oil cooler on the car-
Copper continues to increase, reading more than 3-times higher than universal averages, which
are based on 6,700 miles of oil use. Your oil was in use 1,086 miles longer, but copper is not a metal that
typically increases with miles of oil use. So it appears your M54 has a bushing that is wearing poorly. One
other source could be a crack in an oil cooler, if your car has one. Oil viscosity was in the 10W/40 range.
The TBN was 1.3, showing very little active additive. We suggest short (4K-mile range) oil changes. That
can help control accumulation of copper in the oil.
I pulled about 1/2 a quart for the 5100 mile UOA - replaced it with Red Line 5w-40 (old formula). The oil was changed this time with fresh 5w-40 from Red Line (from Racer Parts Wholesale in Indianapolis).
