20 views

Not changing your oil for a year can be harmful to your engine, especially if you've driven more than the recommended oil change interval (typically 5,000 to 7,500 miles for most vehicles). Old oil becomes less effective at lubricating and cleaning the engine, potentially leading to increased wear and damage. To protect your engine, check your car's manual for the recommended oil change schedule and consider getting an oil change soon if you're overdue.
