The best solution to fix high oil consumption in a Changan Karvaan depends on the severity and cause of the issue. If the oil loss is due to internal engine wear — such as worn piston rings, valve seals, o r cylinder walls — then a complete engine overhaul o r rebuilding the affected components is the most permanent and effective solution.

Switching oil brands o r using slightly thicker oil like 20W-50 may temporarily reduce oil burning, but this is only a short-term fix and not a cure for worn engine parts.

For a permanent fix, Karvaan owners should have a trusted mechanic:

Inspect valve seals and piston rings.

Check for PCV Positive Crankcase Ventilation valve issues.

Perform a compression o r leak-down test.

If significant wear is found, an engine rebuild o r replacement is recommended to stop oil burning permanently.
