Fixing a car that burns oil involves identifying and addressing the underlying cause. Common issues include worn piston rings, valve seals, or a damaged engine. Start by checking for easy fixes like a loose oil cap or a leaking oil filter. If these aren't the culprits, consulting a professional mechanic is advisable. They may recommend a compression test to diagnose the problem further. In many cases, engine repair or replacement might be necessary, although using a thicker grade oil or oil additives can sometimes reduce oil consumption temporarily.
