What is the method for managing oil burning without dismantling the engine?

The method for managing oil burning without dismantling the engine is: heating the cleaning agent while the piston moves up and down slightly, allowing the cleaning agent to penetrate deep into the piston rings for cleaning. The reason for oil burning is: after the engine has been running for a certain period, the width of the piston rings decreases, their elasticity weakens, and the gap between the rings increases, leading to more oil in the gaps. When the piston moves upward, the oil is scraped into the combustion chamber and burned along with the air-fuel mixture, resulting in oil burning. Oil burning in a vehicle can cause the oxygen sensor to fail prematurely, increase carbon deposits in the combustion chamber, lead to unstable idling, reduced acceleration, increased fuel consumption, and excessive exhaust emissions. In severe cases, it can result in insufficient engine lubrication, causing irreparable damage or even complete engine failure, significantly increasing repair costs and posing potential safety hazards.
Oh, let me talk about this topic. As someone who frequently repairs cars, oil burning issues are quite common, and there are several no-disassembly methods. First, use specialized oil additives, such as piston ring restorers, which can seep into and seal gaps to reduce oil leakage. I've seen many car owners experience reduced oil consumption after adding them. Second, switch to higher viscosity oil, like using 5W-40 instead of 5W-30, which better resists burning. Third, perform internal engine cleaning—no-disassembly carbon cleaning products are quite effective—just pour them into the oil system to clean where piston rings get stuck. Fourth, check the PCV system; a clogged ventilation system increases oil consumption, and cleaning or replacing the PCV valve can fix it. Finally, driving habits are also key—gentle acceleration and avoiding high RPMs help protect the engine. These methods work well for mild to moderate oil burning, but if it's severe, you’ll need a professional technician for disassembly and repair. Give them a try—they can save you a lot of time and money.
