What to Do When a Gasoline Engine Burns Engine Oil?

Replacing key components such as piston rings, pistons, main crankshaft bearing shells, connecting rod bearing shells, and crankshaft thrust washers will resolve the issue. Below is a related introduction: 1. Cause: Excessive wear of engine-related components can lead to excessive clearance, causing an excessive amount of engine oil to splash onto the cylinder walls, far exceeding the oil ring's scraping capability. Excessive clearance in the crankshaft bearing shells can result in engine oil leakage from one or more pressure-lubricated bearing shells, leading to engine oil burning. 2. Burning Engine Oil: 'Burning engine oil' refers to engine oil entering the engine's combustion chamber and participating in combustion along with the air-fuel mixture. The occurrence of 'burning engine oil' in a vehicle can cause rapid damage to the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idling, reduced acceleration power, increased fuel consumption, and excessive exhaust emissions, among other adverse effects.
Last month, my old car started burning oil, but I didn't pay much attention at first until I noticed blue smoke from the exhaust, which prompted me to take immediate action. At the repair shop, they diagnosed it as leaking valve stem seals due to aging. Replacing them cost some money, but it solved the problem. Burning oil not only wastes money but can also damage the engine's core components, leading to doubled repair costs in the long run. I recommend regularly changing to high-quality engine oil and keeping the crankcase ventilation system clean to slow down component wear. Before long highway trips, I always check the dipstick. If I notice the oil level dropping quickly, I send it for repair early. Prevention is better than cure—don't skimp on regular maintenance to avoid bigger troubles later.
