Well i changed the oil this weekend during the 4 days its taken us to get correct brake shoes and everything put together. It had Rotella T6 5-40 in it, with around 3k miles, and its been in there since i think last May or April. In that time i blew up a converter, swapped HPOP's, and swapped injectors. Anyways i changed to Valvoline Premium Blue 15-40, not the synthetic stuff. Truck runs better and is quieter than before. Also had a racey idle and the RPM's constantly went up and down, and it seemed to smooth that out a little bit.
So IDK if the difference is going from somewhat worn out oil to fresh oil, or from Rotella to Valvoline, but i actually noticed a difference this oil change compared to changing the Rotella and never noticing a difference. :shrug:
