How Many Liters of Engine Oil Should Be Added During Maintenance?

Small-displacement vehicles require approximately 3.2~3.6 liters of engine oil per maintenance, while larger-displacement vehicles need around 4.5 liters. The specified oil volume varies by manufacturer and model, so always refer to the vehicle's owner's manual. Additional information about engine oil is as follows: 1. Engine oil is a specialized lubricant used in internal combustion engines, serving functions beyond lubrication, including cleaning, rust prevention, and cooling. 2. Overfilling engine oil can increase the amount of oil splashed onto the cylinder walls by the crankshaft and connecting rods, raising crankshaft rotation resistance, reducing engine output power, and increasing fuel consumption. 3. It is advisable to maintain the oil level slightly below the MAX mark on the dipstick. Engine oil dipsticks have upper and lower limits, and the oil level should always be between these two marks.
I remember during my last car maintenance, I checked the owner's manual and found it required 4.8 liters of engine oil. This is definitely not something to take lightly, as every vehicle is different. My engine is a 1.8T, with compact cars generally needing around 4 liters, while larger SUVs may require over 6 liters. The manual specifies it clearly—it's best to follow the exact amount, not estimate. Too little oil can cause engine overheating and accelerated wear; too much oil increases pressure, potentially leading to leaks or foaming. During maintenance, I make it a habit to check with the dipstick: after running the engine for a few minutes and turning it off, the oil level should be between MIN and MAX, ideally in the middle. Seasonal changes also matter—thicker oil in winter requires extra attention. Regular oil checks prevent major issues, extend engine life, and save on repair costs. Developing this habit keeps your car running smoothly and reliably for years.
The amount of engine oil added is crucial—even a one-liter difference can cause engine issues. Once, during a long drive, I added 4.5 liters when the manual specified 4.8 liters, and the car suffered from insufficient oil pressure halfway. Now, for every maintenance check, I always confirm with the manual: small cars usually require 4-5 liters, while SUVs or high-performance vehicles may need up to 6 liters. After adding oil, let the engine idle for 2-3 minutes before checking the oil level—don’t rush to hit the road. Too little oil can lead to overheating and friction, while overfilling strains the oil pump and may cause leaks. Since vehicle conditions vary, checking the oil level every 5,000 km or six months is the safest practice. This habit prevents unexpected issues, ensures safety, and makes driving smoother. Don’t be lazy—details determine success.
