I went a tad early for my first free oil change at just a hair over 3K miles instead of the recommended 3750. The tech took a sample for me as I requested. It was taken from my car and mid stream during the drain. I watched so there was no dipping in the mystery fluid container.
Sent the sample in and here are the results.
I am due in again at the 7500 mile point to get the tires rotated and another oil change so this batch of Subaru 0w20 will get about 4500 miles. After that the 7500 mile OCI is what is prescribed. That will kinda depend on the results on the next couple UOA results I get. I think I'd feel better with 5K OCI.
