How to Add Engine Oil for BMW?
3 Answers
BMW engine oil addition method is: 1. Lift the car, remove the protective plate, and place a container of about 10 liters under the oil drain screw; 2. Unscrew the oil drain screw, use an air gun to blow at the oil filler port for two minutes, tighten the oil drain screw after draining, and wipe it with a tissue to check for oil leakage; 3. Reinstall the protective plate and lower the car, then use a funnel to add oil at the oil filler port. The functions of engine oil are: 1. To alleviate friction and high temperature; 2. To reduce gas leakage and prevent external pollutants; 3. To prevent contact between water, air, acidic harmful gases, and parts; 4. To buffer the pressure rise at the engine cylinder port; 5. To flush away dirt generated on the working surfaces of parts.
As a new BMW owner, I would first park the car on a flat surface and turn off the engine, waiting for it to cool down to avoid burns. Then, I would open the hood, locate the dipstick hole, pull out the dipstick, wipe it clean with a tissue, reinsert it, and then pull it out again to check the oil level marks. If it's below the Min line, I need to add oil. I would open the oil filler cap and pour in new oil, using a small funnel to prevent spills. I would add the recommended type, such as 5W-30 or 10W-40, not pouring it all at once but adding small amounts—about 0.5 liters at a time—then stopping to recheck the dipstick. The goal is to keep the oil level between the Min and Max lines. Since engine oil degrades quickly, it's best to check the oil level monthly to prevent excessive engine wear. Finally, I would start the engine for 30 seconds to check for leaks before finishing up. I recommend buying BMW-specific engine oil to ensure brand compatibility.
I've been driving a BMW for over a decade and am quite skilled at handling oil top-ups. After turning off the engine, wait for it to cool, then pull out the dipstick to check the level - the middle position is ideal. When the oil is low, I use a funnel to pour it in slowly, always using the manufacturer-recommended oil specified in the manual, like BMW's own branded oil containers, avoiding random other brands. Take your time during the topping process - don't pour too much, as overflow can pollute the environment and damage the engine. Regularly check the oil color; if it's too dark or foamy, replace it entirely rather than just topping up. Remember to adjust the topping frequency based on mileage - I check the oil level every 5,000 kilometers. Combining this with regular oil filter changes provides better maintenance for the entire system and extends its lifespan.
