I purhcased this vehicle used a few months ago. This is the first analysis I have done on it. As Blackstone suggested, the high sodium may be from the previous oil fill. I have no idea what oil was used previously. The wear looks good and the coolant level is stable, so I expect to see lower sodium on the next analysis. I am currently running GC 0w-30 in this vehicle. The engine runs smoother and quieter with the GC with no discernable change in mpg. I am doing short runs (4K miles) of several oils to see how they perform in this vehicle. After the GC, I will be running RTS 5w-40.
