Ashton, here is my latest one. Previously you were kind enough to give me some advice here.
I ended up changing my oil then, at about 37,868 miles. At that time I also cleaned my air filter out. My latest analysis with 10,200 miles on DEO & AeO52 shows copper at an elevated level, though not as high as before. 296 now vs 414 previously. I am in the process of justifying a bypass filter setup to my father, for both of our trucks.
Looking at the two side-by-side it would appear that all of my wear metals are lower than before. I went and looked up DEO and they have it's Total Base Number as 10.4, mine is 5.02. If I learned anything from you last time I don't need to do anything, my TBN is higher on this analysis and all of the wear metals are lower.
