A good practice is to back off clicker type torque wrenches to zero after use to avoid having the wrench go out of calibration.
Just saying but it is not advisable to oil bolt threads prior to torquing unless the spec value specifies "wet torque".
For this size bolt oil would add another 3000-4000 pounds tensile load to the bolt, possibly exceeding the yield strength...causing clamping failure, particularly for bolts of unknown origin.
On the flip side..make sure internal and external threads are clean..and dry.
