What happens if too much engine oil is added to a car?
1 Answers
Adding too much engine oil to a car can lead to increased fuel consumption. During operation, the crankshaft and connecting rod big end will undergo intense agitation, increasing internal power loss in the engine. Additionally, more oil will splash onto the cylinder walls, potentially causing oil burning and exhaust issues. Therefore, the oil level should be maintained between the upper and lower marks on the dipstick. Below is some relevant information about engine oil: 1. Engine oil significantly impacts the performance and lifespan of the engine, so it is crucial to strictly follow the vehicle's manual to select oil of the same series, service grade, and viscosity grade. The oil recommended in the manual is determined based on the engine's performance and the ambient temperatures in the sales region, providing essential guidance for oil selection and leaving a considerable safety margin. It is also one of the prerequisites for warranty claims during the engine's warranty period. 2. Select the viscosity grade based on the engine's technical characteristics. For new engines, choose oil with lower viscosity to ensure proper break-in during the initial use period. For older or more worn engines, opt for higher viscosity oil to maintain the required oil pressure and ensure adequate lubrication.
