Can worn-out piston rings cause high oil consumption in my Suzuki Alto Lapin?

One of the primary reasons for excessive oil consumption in any vehicle is worn-out piston rings. How do faulty piston rings contribute to oil burning, and how can this problem be diagnosed and repaired in the Suzuki Alto Lapin?

Yes, worn-out piston rings are one of the main causes of high oil consumption. The piston rings seal the combustion chamber, ensuring that oil doesnt seep into the cylinder and get burned during combustion. When these rings wear out o r become damaged, oil can pass through into the combustion chamber, causing it to burn off and result in increased oil consumption.

Symptoms of Worn Piston Rings:
Blue smoke from the exhaust when accelerating o r decelerating.
Increased oil consumption without visible leaks.
Loss of engine power o r poor performance.
Diagnosis:
To confirm if the piston rings are worn, a compression test o r a leak-down test is required. These tests measure the pressure within the cylinders and check for leaks. A significant in pressure indicates that the piston rings are failing.
Solution: If worn piston rings are the cause, replacing them requires a major engine overhaul, which can be costly. However, this is the most effective way to stop excessive oil consumption in this case.
