There are a few things you can do to check if your car is burning oil. The most common way to test this is to drive the car around and see if it makes any noise when the oil is hot. If the noise is consistent, then your car may be burning oil. Another way to check this is to use a fuel-testing kit that you can buy at a store or online. This kit will test the fuel in your car and give you an idea of how much oil it’s using.
