Thanks for letting us know about track use being a factor. Aluminum is more than twice average and iron could also be considered high for mileage on the oil, but harder use and maybe also lingering wear-in could explain these results. We certainly wouldn't rush to assume a problem in this low-mileage engine - rather, just try an oil change soon and check back in about 2,000 miles for a good comparison. For reference, averages are based on a 2,900-mile run. The TBN is strong, and no contamination showed up. Moly is just from anti-wear additive in the oil.
