Yes, overfilled oil can cause low oil pressure. Excessive oil can cause aeration or foaming, leading to the oil pump struggling to maintain pressure. This aerated oil doesn't lubricate the engine components properly, potentially causing engine damage. Always check the dipstick and consult your vehicle's manual to ensure you're maintaining the correct oil level for optimal engine performance.
