How Many Liters of Engine Oil Should Generally Be Added?

[Calvin]

The amount of engine oil to be added at one time depends on the type of engine. Generally, small-displacement vehicles require 3.2~3.6 liters of oil per maintenance, while larger-displacement engines need about 4.5 liters. Measure by observing the dipstick—the oil mark should be between the upper and lower lines on the dipstick, slightly above the middle line. Each car model has a different capacity, so the amount of oil added varies and should be slightly below the upper mark on the dipstick. Here is some relevant information: 1. Adding too much oil increases the resistance of the crankshaft's rotation, reduces the engine's output power, and causes excess oil to enter the combustion chamber, leading to oil burning, blue smoke emission, and increased fuel consumption. It also accelerates wear on the cylinder and piston, reducing the vehicle's lifespan. 2. If the oil level is too low, some engine components, such as the cam tappet and valves, may not receive sufficient lubrication, resulting in part wear and even severe incidents like cylinder scoring or bearing seizure.
