It would be better to see this spreadsheet history when I list the newest oil sample. Early results start on the left & latest samples to the right or just look at the dates towards the top. This truck blew the notorious EGR cooler but was fixed right before I bought it. You can see the Sodium decline over time & the Potassium is less clear since I use different UOA labs. Towards the right I have universal averages for this engine along w/Avg's of each sample.
