Mobile 1 10W/30, 4450 miles on the oil. 13 months since previous change.
2000 Nissan Frontier 3.3L V6 with 52,700 miles on vehicle
Daily driver, Less than a 10 mile commute plus errands, occasional longer trips on the weekends.
This last winter it was parked outside, not plugged in, and started readily every morning in all Montana weather including -25F (-32C).
Kinda looks like I need to get a block heater, and switch to an oil that can better handle cold starts. 0w-20, and something other than Mobile 1 maybe?

Wear metals were quite high in this sample from your Nissan. Universal averages show typical wear levels for this type of engine after about 4,400 miles on the oil. There's no obvious explanation for the wear, so it's hard to say what's causing it. Aluminum is from the pistons and iron is from steel parts. Copper and lead generally show bearing. Copper can also be from any other brass/bronze part. No coolant was found and the trace of fuel isn't an issue. If the engine saw any hard use or recent work, that might explain it.
Resample in around 3,000 miles.
