Thanks for posting the VOA's, PiperOne!
I'm currently using Delo 400 SDE 15W40 in my 12.7 liter Detroit Series 60. I have a UOA sample from my last PM service, that I haven't sent to the lab. After this run, which will be in another 8000+ miles, I'm switching over the Delo 400 XLE 10W30, which I use through the coldest months of winter.
I'm not familiar with the Klondike brand, on paper it looks very solid.
Thanks again!
