Oil consumption without visible leaks may be due to internal engine issues, such as worn piston rings or valve seals, causing oil to burn within the combustion chamber. Another possibility is a PCV (Positive Crankcase Ventilation) system malfunction, allowing oil to enter the intake manifold and burn. A thorough inspection by a professional mechanic can diagnose and address these internal concerns effectively.
