Excessive oil consumption can result from:

Worn Piston Rings o r Valve Seals: These allow oil to seep into the combustion chamber and burn off.

Turbocharger Issues: If the turbocharger’s seals o r bearings fail, oil can leak into the intake system.

Poor Quality o r Wrong Oil: Using non-recommended oils o r cheap substitutes accelerates wear and oil burn.

Irregular Servicing: Delayed oil changes and poor engine maintenance cause sludge buildup and wear on engine parts.

Driving Conditions: Stop-and-go traffic and high engine loads in Pakistan’s climate can increase oil consumption.

Monitoring oil levels regularly and servicing with genuine parts and recommended oils help prevent major damage.
