How Many Milliliters of Engine Oil Should Be Added?
1 Answers
During maintenance, the amount of engine oil to be added at one time depends on the type of the engine. Generally, small-displacement vehicles require 3.2~3.6 liters of engine oil per maintenance, while larger-displacement engines need around 4.5 liters. The engine oil level should neither be too low nor overfilled. Below are the impacts of overfilling or underfilling engine oil: 1. Overfilling engine oil: This increases the resistance of the crankshaft rotation, reduces the engine's output power, and the excess oil may enter the combustion chamber and participate in combustion, leading to oil burning, blue smoke emission, increased fuel consumption, and accelerated wear of cylinders and pistons, thereby shortening the vehicle's lifespan. 2. Insufficient engine oil: Some engine components, such as the cam tappet and valves, may not receive sufficient lubrication, resulting in component wear and even severe accidents like cylinder scoring or bearing seizure.
