All in all, I'm quite pleased with the new CJ4...so I guess I truly believe now that it is as good as the oil companies claim. It was tough to gauge over the last few years with all the skepticism though. 1 Quart added...it was CI4+ (oops).

Blackstone's comments:
DEREK: The low temp viscosity read 119.664 at 40ºC. The high-temp viscosity you can read in the
physical data. You ran this oil a lot longer than the last, and iron improved quite a bit. We are not sure what
sorts of changes you've made sine January 2007, but we certainly like how this engine is wearing. Metals
are properly balanced and everything read within the average range for the Cummins 6BT engine. The oil
was in good shape physically, containing no moisture, fuel, or signs of coolant. You could run the oil longer, if you wanted! Nice engine.
