How Many Milliliters of Engine Oil Should Be Added?

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.

I often get asked how many milliliters of engine oil to add, but it really depends on the specific car model and engine size. Having driven many cars myself, I've found that regular sedans or compact SUVs typically require about 4 to 6 liters of oil, which is 4000 to 6000 milliliters. However, don't just guess—the best approach is to check the owner's manual, where it's clearly stated. Can't find the manual? No worries, you can use the dipstick—just fill it to the middle mark between the lines. Adding too much can cause oil foaming or leaks, while too little leads to faster engine wear. I recommend using an electronic scale to weigh the empty oil container during each oil change, keeping in mind that 4 liters equal 4000 milliliters for easier estimation. Beginners should follow these steps carefully and avoid rushing, or else the repair bills won't be cheap.

Speaking of engine oil quantity, I've changed oil many times myself, from old Fords to new electric vehicles. Most cars take between 4-6 liters, roughly 4000-6000 milliliters. Once I only added 3 liters to my small Toyota, and after just 100 kilometers, the dashboard light came on. Checking the dipstick showed it was too low, so I had to top it up immediately. The lesson is: don't rely on guesswork, always check the new car's manual; for older cars, if unsure, start with 4 liters and then add slowly while checking the dipstick. Adding too much oil can dirty the engine compartment, and oil stains are hard to clean. Finally, a reminder: when changing oil, drain the old oil completely before adding new oil, and don't mix different brands.

I'm the hands-on type, how many milliliters of oil to add? Simply put, it depends on the car model. Sedans usually take 4-5 liters (4000-5000 ml), while SUVs or high-displacement engines might need 6 liters. No manual? Use the dipstick as your guide: after adding oil, the level should be between the upper and lower marks. Remember, overfilling can cause foaming and oil leaks, while underfilling leads to insufficient lubrication and accelerated wear. In practice, I often use a 5-liter oil jug as reference. Newbies, take it slow and follow step by step.
