No such thing as break in oil these days... Same oil in a new rig as a used rig... More about HOW YOU DRIVE IT.... Easy starts... mediocre speeds.... ramp up RPMs..... Couple hard pulls on the torque band.... NO LONG RUNS...... But oil is the same... Have you checked your fluids? Do you have heat? If so, have you tried running it with the heater on? Maybe it is overheating? And the light is not coming on??? I JUST HATE ELECTRICAL ISSUES!!! SO HARD TO DIAGNOSE!!!
