Why is my car buring oil? When you start to think your vehicle is burning oil, don't hesitate to bring your vehicle to our shop. When your vehicle starts to burn oil, it usually is a result in worn out parts. Worn out seals or piston rings can lead to a vehicle burning oil. The vehicle's seals and piston rings work to keep the engine oil out of the combustion chamber. The combustion chamber is the area where fuel and air mix is ignited. It is also possible that your car is burning oil on the outside of your vehicle. This is because your vehicle's engine oil is leaking out and landing on a hot surface. Call us today if you suspect your vehicle is leaking oil to schedule an appointment. Our service team is ready to serve you!
