I forget which forum I usually post these in... :shrugs: Anyway, as I have been doing for every oil change, below are my oil test results for anyone interested.
Oil: Amsoil Signature Series 0W-30
Filter: Amsoil EA15K10, 98.7% 15 micron filter
About 6 months and 5,000 miles
Some notes: My fuel...
As usual, I run an oil analysis on a sample of my oil around every 5,000 miles.
Below are the results.
(Note that Sample #1 is Royal Purple, the rest are Amsoil's Signature Series)
This most recent sample I didn't run it as long because I wanted to send the sample in at 100,000 miles...
