The BMW 525 does not have an oil dipstick. You can check the oil level on the dashboard inside the cabin. The functions of engine oil are: 1. Reducing friction and high temperatures; 2. Cooling and temperature reduction; 3. Cleaning and purifying; 4. Shock absorption and cushioning; 5. Rust and corrosion prevention. Taking the BMW 525 2021 Sport Package as an example, its body dimensions are: length 5106mm, width 1868mm, height 1500mm, wheelbase 3105mm, and fuel tank capacity 68 liters. The BMW 525 2021 Sport Package is equipped with a 2.0T turbocharged engine, with a maximum power of 135kW and a maximum torque of 290Nm, paired with an 8-speed automatic transmission. The front suspension uses a double-wishbone independent suspension, and the rear suspension uses a multi-link independent suspension.

As a long-time owner of a BMW 525, let me share some experience. The oil dipstick location is actually quite obvious—after opening the engine hood, it's located at the front right side of the engine, near the engine block, usually marked by a yellow plastic ring. Pull it out, wipe it clean, reinsert it, and then check the oil level line. However, I must remind you that many newer BMW 525 models now use an electronic system where the oil level can be directly displayed on the dashboard—my 2015 model automatically detects it this way. If you can't find a physical dipstick, it might be due to upgraded technology, so don’t waste time searching hard. I frequently check the oil—every few thousand kilometers—to ensure timely top-ups if the level is low. Otherwise, engine overheating can damage internal components, which could lead to costly major repairs. I recommend confirming your model year first; for newer models, simply use the central console menu options for a more hassle-free and efficient check, ensuring safer driving.

As a mechanic who frequently works on BMWs, when dealing with models like the 525, the oil dipstick is typically located near the oil pan in the lower right corner of the engine bay. After parking, ensure the engine has cooled down, then open the hood to locate the small plastic handle, pull it out, wipe off the old oil residue, reinsert it, and check if the oil level is between the MIN and MAX marks. In reality, car owners often overlook this step—oil buildup can obscure the marks or a loose dipstick may lead to misreading. Modern BMW 525 models, especially those post-2010, mostly use electronic monitoring, allowing you to check the oil level with a single click in the iDrive system menu. If you insist on manually locating it, it’s usually at the front of the engine, but avoid touching hot components to prevent burns. In short, oil maintenance is crucial—regular checks can prevent engine damage due to low oil levels, saving you the hassle and cost of major repairs. If you’re unsure, always refer to the manual or visit a professional shop rather than taking risks.

As a new owner of a used BMW 525, let me share my experience. Initially, I didn't know where the oil dipstick was. After opening the engine hood and searching around, I finally found a small pull ring at the front of the engine. The location can sometimes be hard to spot, especially when covered by dust in the engine compartment. But in my 2007 model, it's installed right there—just carefully pull it out, clean it, and check the oil level. However, I've heard newer models have switched to electronic displays, allowing you to check the oil status directly on the central control screen. A word of caution: always check after the car has cooled down post-parking—safety first. Don't be reckless like I was at first, fiddling around until a friend taught me the proper way. Regular checks are crucial; top up the oil when low to keep the engine running smoothly.
