Excessive engine oil consumption means the engine is consuming more oil than it should during operation. This could be due to several reasons:

Possible Causes:

  1. Worn Piston Rings or Cylinders:

  2. Turbocharger Issues:

    • A faulty turbo seal can allow oil to leak into the intake or exhaust, burning off in the process.
  3. Valve Seal Problems:

    • If the valve seals are worn, oil can seep into the combustion chamber and burn with the fuel-air mixture.
  4. PCV (Positive Crankcase Ventilation) System Failure:

    • A clogged or malfunctioning PCV valve can cause oil to be sucked into the intake manifold.
  5. Oil Leaks:

    • External leaks (gaskets, seals, or turbo oil lines) could also contribute to oil loss, even if it's not being burned internally.

What to Look For:

  • Blue Smoke: If oil is being burned, you may notice blue smoke from the exhaust, especially when accelerating or starting the engine.
  • Low Oil Level: You may need to top off the oil frequently between oil changes.
  • Loss of Power: Turbo issues can also affect engine performance.
  • Oil Residue or Leaks: Check for visible oil leaks under the car or near the turbo.

What You Should Do:

  1. Inspect for Leaks:

    • Ask your mechanic to check for any external oil leaks around the engine, turbocharger, and gaskets.
  2. Check Compression and Turbo Condition:

    • A compression test or leak-down test can help diagnose worn piston rings or valve issues.
    • Inspect the turbocharger for oil leaks or damage to the seals.
  3. Monitor Oil Usage:

    • Regularly check your oil levels and keep track of how much oil is being consumed over time.
  4. Repair as Needed:

    • Depending on the issue, repairs may include replacing worn piston rings, valve seals, or repairing/replacing the turbo.
