Your car can run for a while if it’s burning oil, as long as you keep adding engine oil when it gets low. There are, however, issues that will come up. The engine will run rough, because oil doesn’t burn properly in the cylinders. Spark plugs will become fouled by oil, turning on the Check Engine light.
It is a fact that most engines will burn some oil. The majority of manufacturers consider one quart of oil in the range of 1,500 miles to be acceptable. It should also be pointed out there are some performance vehicles that will consume a quart of oil in less than 1,000 miles and is also considered acceptable.
