This was my first run with CI-4+ Delo 400 in my '04 GMC Sierra, & I'm pretty pleased, to say the least. 8,345 on the oil, & ~96k total actual miles on the engine.

Mobil 1 oil filter & AC Delco air filter. No make-up oil added or needed. I didn't feel like spending the extra $10 on a TBN this time, since it's always been in good shape during the previous 6 UOAs on this truck.
With Delo 400 giving me such good results, I'm going to hate to put in 5w-40 synthetic when the weather starts getting colder.
