Here are the results of my first UOA on my 2012 Nissan Xterra Pro4X 4x4 4.0 Truck, Truck had 86,179 miles at this OC, I have owned the truck since new and am looking at extending my OC intervals because I now drive about 2000 miles a month with very little stop and go, I also want my timing chains to last a good long time as the truck is paid off now.. The previous 2 runs were also M1EP 5w30 SN with Purolator PureOne filter's (Yellow with grit) (Bought a case a few years ago) . I refilled it with more M1EP 5w30 and a Fram Ultra. I am glad that the Insoluables look good as we live in an Extremely dusty dirt road neighborhood and I have run an AEM Brute Force Intake (non-oiled) since around 10k miles on the truck. The truck also has Hypertec programming and a Magnaflow Exhaust. The oil in this sample also had some very rough off-roading on it as well.. The truck parks outside every night so it gets some cold, cold starts as well...
This OCI was 3 months time-wise...
