Engine oil is absolutely essential for your car (engines can run without oil for less than 30 minutes). And it's not just the quantity of oil that's important. It's also vital that the oil quality is good.
"Dark colored, cloudy or gritty textured oil is a sign the lubricating components of the oil have been exposed to heat for too long and needs to be changed. Adding oil instead of an oil change at this point could cause engine issues. This used oil needs to be removed to allow new oil to lubricate your engine's parts." Global Automotive Jan 17 2020
In short, you need to check your oil regularly, and top up or change as required.
