What type of engine oil is used in the BMW 5 Series?
2 Answers
The BMW 5 Series uses 5W30 engine oil. Engine oil, also known as motor lubricant, serves multiple functions such as lubrication, friction reduction, auxiliary cooling, sealing, rust prevention, and shock absorption. Taking the 2021 BMW 5 Series as an example, its body dimensions are: length 5106 mm, width 1868 mm, height 1500 mm, with a wheelbase of 3105 mm and a fuel tank capacity of 68 liters. The 2021 BMW 5 Series is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 184 HP and a maximum power output of 135 kW. It is paired with an 8-speed automatic transmission. The front suspension features a double-wishbone independent suspension, while the rear suspension utilizes a multi-link independent suspension.
I've been driving a BMW 5 Series for several years, and engine oil is quite particular—it depends on the model year. Generally, for older models like my 2015 version, BMW recommends using fully synthetic 5W-30 oil that meets the LL-01 standard. It ensures proper engine lubrication and protection, preventing excessive friction. For newer models post-2020, they’ve shifted to LL-04-standard 0W-30 or 5W-40 oils, which are more eco-friendly and fuel-efficient. I always change the oil on time, roughly every 8,000 kilometers—don’t delay too long, or the oil degrades, leading to carbon buildup and increased engine noise. The manual spells it out clearly; flipping through it before doing anything is a must. For city driving, avoid overly high viscosity. In colder regions, consider 0W-30 for quicker, smoother starts. Stick with reputable brands like Shell or Castrol—long-term use extends engine life and keeps driving hassle-free. Oil quality directly impacts power output, so don’t skimp and buy subpar products.
