This is my third sample on this vehicle. The truck had 26592 on it when the sample was taken, I did not change the oil just the fleetguard stratapore and add one quart of oil. The truck has TST powermax on it with the amsoil ea air filter. My first two changes I was using rotella dino and the iron ppm was 46, so it looks like the amsoil is working good. Also note copper in the first uoa was 4, 7 in the second UOA with 4800 miles on the oil. Anything not shown was zero. I am open to discussion and I am waiting for my hard copy in the mail for the complete particle count. I did the particle count mostly because I am waiting on an amsoil bypass and wanted a comparison when I did my first uoa with it installed. Truck is driven mostly on weekends towing 5-8k and running around here and there during the week. I plan to sample again at 12k on the oil.
