Monitoring your oil level frequently using the dipstick and noting a consistent drop between scheduled changes can also reveal a problem before it becomes severe. Worn piston rings are a primary culprit, as they fail to scrape excess oil off the cylinder walls effectively, allowing it to enter the combustion chamber.

Similarly, deteriorated valve seals can leak oil past the valves into the cylinders, where it is burned off during operation. The accumulation of carbon deposits within the combustion chamber can degrade engine performance and reduce fuel efficiency.
A simple test involves checking the color and density of the smoke; blue or gray smoke typically indicates burning oil, while white smoke suggests coolant burning and black smoke points to a rich fuel mixture. Depending on the findings, repairs may range from replacing faulty valve seals or piston rings to addressing more complex issues like a malfunctioning PCV valve or a clogged oil filter housing.

This visible sign often indicates your engine is burning oil, a condition that requires prompt attention to prevent further damage. A mechanic can perform a differential pressure test or a leak-down test to determine if the issue lies with the piston rings or the valve guides.
