Been using Rotella T6 synthetic 5w40 (with minimal troubles this far. dealer said synthetic blend, I went full synth) every 8k miles (book mileage for biodiesel blend fuel 10k oil changes for full D2 diesel)The main bearings are unlikely to fail on the V6 if you use 5w40 oil, which is what the manufacturer intended. Chrysler tried to coax better EPA numbers out of the truck and specified 5w30. That didn't work so well. They've since switched to 5w40.
I have noticed the engine has an odd clatter when no load rolling at times, (only heard windows down on the road at idle passing a bridge or building)
I drive past a concrete wall coming up to a stop sign on my way home, hear almost metallic clunking, but do not feel or hear anything in the drive train. acceleration quickly takes away the noise. the sound is different from the no fuel injection idling.
