How Many Liters of Engine Oil Does a BMW 525 Need?
2 Answers
BMW 525 requires approximately 5 liters of engine oil. Engine oil, also known as motor lubricant, serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing to prevent leaks, rust and corrosion protection, as well as shock absorption. The BMW 525 is a mid-size sedan produced by BMW. Taking the BMW 5 Series 2021 525Li M Sport Package as an example, its body dimensions are: length 5106 mm, width 1868 mm, height 1500 mm, with a wheelbase of 3105 mm. The BMW 5 Series 2021 525Li M Sport Package is equipped with a 2.0T 184 horsepower L4 engine, delivering a maximum power of 135 kW and a maximum torque of 290 Nm, paired with an 8-speed automatic manual transmission.
I've been driving a BMW 525 for several years, and it usually takes about 5.25 liters of engine oil for each maintenance. Mine is a 2015 model with the N20 engine. If the oil filter isn't changed, it requires slightly less, around 4.8 liters. A special reminder: don't rush off after an oil change. Once, the mechanic added half a liter too much, and the next morning during a cold start, the engine felt sluggish—the oil level was above the max mark on the dipstick. Checking it yourself is actually quite simple: turn off the engine, wait five minutes, pull out the dipstick, wipe it clean, reinsert it fully, and if the oil mark is between min and max, it's just right. Interestingly, the older B48 engine in the 525 only requires 4.8 liters, so it's best to check the user manual for your specific model before maintenance. By the way, 0W-30 full synthetic oil is the most suitable for this car—never use mineral oil.
