My first oil analysis in this car. About a 50/50 blend of city and highway driving, approximately 300 miles per week. The car was at the dealership getting some warranty work done which resulted in multiple starts, so that is probably to blame for the fuel dilution and low flashpoint. I normally shift around 3,000 rpms until the car is fully warmed up with occasional spirited driving after that. Thoughts?

Blackstone's comments:
Your Volvo is wearing well at 15,200 miles and is apparently past break-in here in the first sample. We did find some fuel, present at 0.8%, but it's likely from the city driving you mentioned and it hasn't affected wear, though we'll keep an eye on it next time. Universal averages are based on an oil run of 5,500 miles. Your oil run was just short of this and wear looks much better and in the proper balance to indicate normally wearing parts inside your engine. The TBN read 2.8, showing some active additive left. 1.0 is low. Try 6,000-7,000 miles next time.
