Yes, too much oil can cause a seized engine. Excess oil can lead to increased pressure in the crankshaft, causing foam and reducing lubrication. This results in friction and overheating, potentially leading to a seized engine. To avoid this, always maintain the correct oil level as recommended in your vehicle’s manual. Regularly check your oil and drain any excess promptly.
