You should not be running 8k miles on Delo...switching to Mobil 1 Turbo Diesel Truck Oil (Synthetic) will do wonders for your engine and longevity. It will quiet down your lifters and make the engine run much more smoothly. I change mine every 9-10k. Others on the forums have done oil analysis on this oil at 10k and it was okay so 10k is fine.
