Oklahoma → Texas · Interstate 35 / Interstate 40
Returning from Oklahoma City, Oklahoma, back to Houston, Texas, the itinerary retraces the same 785 km (488 miles) of the outbound segment, predominantly via Interstate 35 / Interstate 40, adding another 7h 29m to the corporate odometer. Unlike the outbound leg, the homeward journey is usually executed at the close of the business day, when heavy truck traffic, accumulated fatigue, and dropping daylight all demand sharper focus. Anyone hoping to ease the arrival back into Houston, the fourth-largest US city and energy capital of the world, may consider an overnight stop in a midpoint town and splitting the haul into two shorter stints. Fuel expense holds steady near $65.69, totalling roughly 142.8 liters for the entire trip when added to the outbound segment. The return reimbursement reaches $337.55, doubling the aggregate payout for the full journey. Log each leg separately in the Clara receipt, with distinct timestamps, so the paperwork accurately mirrors the vehicle's actual movement.
