This sample is from a friends Tundra with the 4.7 v6. He went 13 months and 21,500 miles on AMSOIL's OE 5w-30 with a Car Quest Blue filter,(pictures in another thread of filter cut open). He kept meaning to come in for an oil change but with his job time got away from him. I need to check his air filter. Here is the Blackstone report.
Code:
Derick's Tundra doesn't look too bad, but there was more aluminum in the sample than we like to see. Iron's up,
too, but that's an element that tracks with miles and is actually good on a per mile basis. Universal averages are for an
oil run of 6,800 miles. Aluminum tends to stick closer to the average, so there was some extra piston wear. The silicon
could show dirt getting past the air cleaner, which would account for the piston wear. The TBN was very low, showing
the oil's additive package was depleted. Drop the interval to 15,000 miles and check back.
