I need to schedule an oil and filter change for my autos either every 7,000 km or every 12 months.
Currently, I own three automobiles. Unfortunately, the one valued at 7,000 currency units is absent. Consequently, I plan to spend a duration of 12 months doing maintenance on one of my vehicles while it undergoes a Ministry of Transport examination. It is worth noting that my acquaintance, who goes by the name of "m8," is the proprietor of the automotive repair establishment. During this time, I will take a short break while the oil is being drained from the vehicle.
