What are the methods to solve engine oil burning without disassembly?

The methods to solve engine oil burning without disassembly are: 1. Replace the exhaust valve to ensure the crankcase vacuum reaches the standard value; 2. Use specialized equipment and professional materials to perform deep cleaning of piston rings and carbon deposits in the cylinder; 3. After completing the entire treatment process, the vehicle needs to be re-inspected after driving 6,000 kilometers according to standard requirements. Engine oil burning refers to the situation where engine oil enters the combustion chamber of the engine and participates in combustion along with the air-fuel mixture. If a vehicle exhibits engine oil burning, it can lead to rapid damage of the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idling, weak acceleration, increased fuel consumption, excessive exhaust emissions, and other adverse effects. In severe cases, insufficient engine lubrication can cause irreparable damage or even complete engine failure, significantly increasing repair costs and posing potential safety hazards.
Last time my old car was burning oil quite badly, so I used a no-disassembly repair method without opening up the engine: adding piston ring restoration additive. This stuff is mixed into the engine oil to help soften aged seals and piston rings, reducing oil entering the combustion chamber. After driving 500 km, I checked and found the oil level had stabilized significantly. But it's not a cure-all—if the engine is severely worn, it might not work. I also paired this with more frequent oil changes, switching to high-viscosity oil every 5,000 km to reduce flow risks. Cleaning internal carbon buildup in the engine is also crucial; I used a dedicated cleaner and let the engine idle for ten minutes before changing the oil. Overall, it's low-cost and convenient, suitable for DIY attempts.
As a daily driver, I've encountered the issue of burning oil several times. Solutions include: consistently using the manufacturer-recommended oil grade, such as 5W-30, and changing the oil every six months to maintain cleanliness; in terms of driving habits, avoiding sudden acceleration and prolonged high-speed driving to reduce engine load; additionally, adding some engine repair additives can temporarily seal gaps. Regularly checking the air filter and PCV valve, and replacing clogged parts can improve oil consumption. These can be done without engine disassembly, saving money and hassle, and proper maintenance can also extend the vehicle's lifespan.
Oil Burning No-Disassembly Repair Options or Maintenance Adjustments: Adding piston ring repair products can provide temporary fixes; switch to thicker oil such as SAE 40; perform engine cleaning to remove carbon deposits; inspect and replace the PCV valve.
