This is a 3.5L I5/auto. K&N replacement filter, 89 octane. A/C delco filter swap at 5K added 1/2qt make up oil. Previous oils were M1 5w/30. Since summer is almost here, I'm thinking filter @4K, oil @8K to bring down the iron number...
The 10,004 mile oil run produced higher wear metal readings in most categories with iron from steel parts being the leader. That is because iron "tracks" with miles of oil use more than any other metal. It reads 2x's the universal averages which are based on a 5500 mile oil run for this engine. The TNB was 2.1, some active additive left. No contaminants were found and air and oil filtration (see silicon and insolubles) were normal. If the iron doesn't bother you, resample at 10K.
