Is 4 liters of engine oil enough for the Roewe RX5?
2 Answers
Adding 4 liters of engine oil is sufficient. The user manual for the Roewe RX5 specifies that the engine oil filling capacity is between 4 to 5 liters, so as long as it falls within this range, it is acceptable. Precautions when adding engine oil: Select engine oil based on the engine's requirements: Do not use high-grade oil in a lower-performance engine, nor use low-grade oil in a high-performance engine. Choose oil that matches the engine. The oil level should be slightly below the mark on the dipstick; do not overfill: Excessive oil not only increases the crankshaft's rotational resistance but also reduces the engine's output power. Moreover, the excess oil may enter the combustion chamber and participate in combustion, leading to oil burning, blue smoke emission, and increased fuel consumption.
I remember when I was driving the Roewe RX5, adding engine oil was something you couldn’t take lightly. Generally, this car comes with either a 1.5T or 2.0T engine, and the standard oil capacity ranges between 3.5 to 4.5 liters, depending on the model year. I once tried adding 4 liters myself, thinking it would be enough at first, but after starting the engine and checking the dipstick, the oil level was still below the MIN mark—not ideal. Later, I learned that when adding oil, you need to account for the residual loss of old oil, so it’s best to drain it completely during an oil change. Adding too much can cause issues like pressure leaks in engine seals, while too little can lead to piston wear. I usually follow the vehicle manual’s recommendation of 4 liters, but after each refill, I make sure to park on level ground, let the engine cool for a few minutes, and check the dipstick to ensure the level is between MIN and MAX. I’d suggest keeping regular maintenance records of oil usage to avoid last-minute surprises. Sticking to this routine long-term saves both hassle and money.
