I still believe I'm the only person with this engine posting UOAs so there is nothing to compare my numbers to. 6300 miles on this fill. 23,800 on the vehicle. Fuel has mostly been commercial Shell B5 with RLI summer additive. Driving habits were mostly local as opposed to highway on my previous UOAs. Iron is lowering nicely. Aluminum slower to respond. High copper reading is component of the oil. The green reference numbers at the bottom are not exact since the formulation has changed somewhat since that VOA was done. I'm still showing some potassium and I still don't know why. I have not lost any coolant. It may be from the bio my local jobber is blending into the D2. Soot is up which disappoints me. I'm either going back to FPPlus or cocktail that with the RLI. Soot could be higher due to short trip driving; I mostly get up to operating temps, but not always. I have changed out the oil filter and will take this fill out closer to 10K, refill with the latest RLI blend and do the next analysis when I have 5K on that fill.
