How Many Liters of Engine Oil Should Be Added During Maintenance?
2 Answers
During maintenance, approximately 3.5 to 5.0 liters of engine oil should be added. Engine oil serves functions such as lubricating and reducing friction in the engine, assisting in cooling, sealing to prevent leaks, preventing rust and corrosion, and cushioning vibrations. The purpose of maintenance is to keep the vehicle clean, ensure normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. Precautions for car exterior maintenance include: 1. Use automotive-specific cleaners and mild soap for washing; 2. When cleaning polished metal parts, use carbon-based cleaners and avoid using hard tools to scrape off dirt; 3. Wax regularly to prevent oxidation of the coating; 4. Pay attention to the welds and seams on the car body, and apply rust-proof treatment to these areas and other parts prone to rust after scratches over time.
The amount of oil required for maintenance varies for each vehicle, primarily depending on engine size and model. For example, my compact car only needs 4 liters, while my friend's midsize SUV requires 5.5 liters, and his full-size pickup truck even needs over 6 liters. It's essential to consult the owner's manual, which provides precise recommendations, typically ranging between 4 to 6 liters. Overfilling can cause excessive pressure, leading to foaming and lubrication failure, while insufficient oil increases friction and damages components. I always go to a professional shop for maintenance, where technicians accurately add oil according to the manual, draining the oil pan before refilling with fresh oil. Checking the oil level is simple: after parking and letting the engine cool for a few minutes, pull out the dipstick, wipe it clean, reinsert it, and ensure the oil level is between the Min and Max marks for safety. Also, make sure the oil type, such as 5W-30, is correct to protect the engine and extend its lifespan.
