Well, this is from my coworker's truck, who was very lax on changing his oil this time around. He went about 11,300 miles on Valvoline Maxlife Synblend. He didn't add any make up oil on the run and only 4 of the 6 qt capacity was left.
ANTHONY: There's quite a bit of metal here. Averages show typical wear for this type of engine after about
5,700 miles on the oil. You're getting a lot more metal in your oil than we'd expect, even for a long oil run
like this. Aluminum, chrome, and iron can show upper-end wear, and iron and lead can show bearing wear.
Nickel is probably a steel alloy. Check the air filter in case silicon is abrasive, though maybe some of this is
wear-in, if you've had work done recently. The sodium is oil additive in this case. Try just 3,000 miles next
oil to flush metals and monitor.
