Does adding 0.5 liters less engine oil have any impact?

Adding 0.5 liters less engine oil has no impact as long as the oil level is between the upper and lower marks on the dipstick. Insufficient engine oil: If the oil level is below the minimum mark, even though there is still some remaining oil in the oil pan, it is necessary to top up the oil as soon as possible, either by visiting a 4S shop or doing it yourself. Additionally, it is important to avoid aggressive driving. When the engine operates at high speeds, the temperature rises significantly. With insufficient oil volume, this can easily lead to engine overheating issues. In severe cases, the engine may even be completely damaged. Excessive engine oil: Adding too much engine oil is also problematic. The excess oil can easily enter the combustion chamber (due to excessive internal pressure) and form sticky carbon deposits. Over time, these carbon deposits will worsen, potentially clogging the catalytic converter, causing excessive exhaust emissions, and in severe cases, leading to oil burning issues.
With decades of car repair experience, I've encountered many such cases. Being short by 0.5 liters of engine oil has limited impact, but it depends on the specific vehicle condition. If your engine's total oil capacity is around 4 liters, being 0.5 liters low might still keep the level between the min and max marks on the dipstick, not causing immediate issues. However, engine lubrication relies on oil circulation - insufficient oil increases friction, leading to premature component wear. Over time, this shortens engine lifespan. I recommend checking the oil level immediately. If it's below the min mark or the oil pressure light comes on, it's best to stop and top up. Develop a habit of checking with the dipstick monthly, maintaining the oil level in the middle range for optimal safety. Remember, engine oil is like human blood - a slight shortage may not cause immediate harm, but should never be taken lightly.
As an average driver, I recently encountered a situation where the engine oil was underfilled during my last service. After driving for a few days, I noticed some unusual engine noises. Upon checking the dipstick, I found the oil level was just slightly above the MIN line, so I bought some oil to top it up myself. Being half a liter short might not significantly impact short-distance driving, but during high-speed driving or continuous uphill climbs, it could lead to higher temperatures, increasing the risk of fuel consumption and wear. Don't panic—as long as the oil level is within the safe range, you can drive to a repair shop for a top-up. Regular checks are crucial; I usually glance at the dipstick every two weeks to ensure everything's normal. Here's a little tip: if the oil is low, the car might start a bit slower with louder noises, which serves as a warning signal.
