Your Car's Oil
The oil in your car's engine acts as a lubricant for the pistons, cylinder walls, crankshafts, and connecting rods. These parts are essential to your vehicle's performance and the oil that keeps them functioning. Routine checks of your car's oil level combined with oil changes will ensure your vehicle continues to run smoothly and efficiently.
Over time, these parts begin to wear, causing the oil to leak into the combustion chamber and the oil to burn. You'll know when your car is burning oil as you'll notice signs such as a burning odor, blue-colored exhaust coming from the tailpipe, or a decrease in your car's performance. Another warning sign can come from a change in your vehicle's fuel economy.
Though it's quite normal for your vehicle to burn oil, too much burning may be a signal that your car needs attention. If your car is burning oil, the first place your service technician should check is under the hood to assess if certain parts such as the piston rings are worn.
