Buick Regal shows 40% oil life remaining, which means maintenance is not immediately required. Oil life is not the same as oil quantity; it's merely a maintenance reminder. If the maintenance reminder was reset after the last service by the technician, you can continue driving until the oil life drops below 10% before scheduling maintenance. Below is an introduction to car maintenance: 1. Introduction to car maintenance: Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of a vehicle, also known as vehicle upkeep. 2. Scope of car maintenance: Modern car maintenance primarily includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and more. 3. Purpose of car maintenance: The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the vehicle's service life.
