The oil dipstick of the BMW X5 is located next to the engine, with a pull ring. Pull out the dipstick, wipe it clean with a towel (or soft paper), then reinsert it into the dipstick slot in the engine. Push it all the way in, then pull it out again to check the oil level. Below is a step-by-step guide on how to read the oil level: 1. Locate the oil dipstick handle in the engine compartment and prepare a piece of tissue. 2. Pull out the dipstick and use the tissue to completely wipe off the oil stuck to the dipstick head. At this point, take note of the position of the dipstick's markings (usually marked with MIN and MAX). 3. Reinsert the cleaned dipstick all the way in, then pull it out again. The oil now sticking to the end of the dipstick can be used for observation. 4. Observe the oil level on the dipstick to determine the highest point of the engine oil inside the engine.

As a seasoned BMW driver with over a decade of experience, let me teach you the most reliable way to check engine oil. The BMW X5 has two methods: mechanical dipstick and electronic detection. For older models, simply open the hood, pull out the orange dipstick, wipe it clean, reinsert it, and then check the oil level. Newer models with electronic oil level display are even simpler: start the engine and drive until it reaches normal operating temperature, then turn off the engine and park on level ground for five minutes. Use the central control knob to navigate to 'Vehicle Status' - 'Engine Oil Level', and wait for the progress bar to complete; it will display the oil level. Key point to note: a yellow warning light doesn’t indicate low oil but rather a detection system malfunction. Last time, my buddy didn’t wait for the engine to warm up before checking, resulting in a false alarm of being one liter short, leading to an unnecessary trip to the dealership.

Last week I just helped my wife check the oil level in her X5 and discovered there's actually a trick to the electronic measurement. You need to wait until the coolant temperature gauge reaches the 90-degree midpoint and then turn off the engine - checking immediately gives inaccurate readings. When navigating to the 'Oil Level' option in the iDrive menu, remember you must press the brake pedal to activate the measurement. Seeing all four bars filled indicates healthy oil level, three bars means it's time to top up, and two bars requires immediate refill. Once before a long trip I noticed it was one bar short, poured half a bottle of 0W-40 into the filler neck, and it showed normal the next day. BMW's design is much more convenient than older cars.

Practical experience tells you three steps to get it done: 1. Park the cold car on level ground and turn off the engine. 2. Press the ignition switch to power on but do not start the engine. 3. Turn the iDrive knob to enter 'Oil Measurement'. Key point: When the progress bar completes, 'OK' indicates it's within the safe range, while 'MIN' means you need to immediately add 1 liter of oil. Hybrid versions are particularly prone to misjudgment. Last time, I got a 'MIN' reading on a garage slope, but after moving to level ground and retesting, it was normal. It's recommended to always keep a 1-liter bottle of LL-04 certified oil in the trunk for emergencies.
