This is a UOA on Formula Shell 5W-30 SM run for one year and 7000 miles in a 2006 Nissan Frontier 4x4 with the VQ40DE engine. The truck has 19,350 miles on it in mixed driving conditions including frequent 4x4 usage. Its most strenuous service included one run up to the top of Mauna Kea (13,900 ft ASL) and back down, with WOT in 2nd gear for much of the drive up and 5000-6000 rpm engine braking coming back down. Added 1/2 qt. of make-up oil. Wix oil filter and OEM air filter. Blackstone did the analysis. Here are the data:

Blackstone's comments: No problems at all showed up in the initial sample from your Frontier, even though you ran this oil longer than you meant to. All wear metals read at or below average for this type of engine, which is a very good indication or normally wearing parts. Universal averages show typical wear after 5,600 miles on the oil. You've gone longer than that so it's impressive that your wear is so much lower. The viscosity was low, but it wasn't due to any fuel, so it's not a problem. The TBN was good at 2.9. Overall, a nice report. You could routinely go 7K miles.
My comments: I had planned to run this oil only 5K miles but got lazy. Looks like no harm done. Considering this oil is SOPUS' bottom shelf brand, I'm pretty happy. Only thing not to like is its falling out of grade.
